Oracle Database Error Messages (ORA-00000 - ORA-01999)
ORA-00000: normal, successful completion
Cause: Normal exit.
Action: None

ORA-00001: unique constraint (string.string) violated
Cause: An UPDATE or INSERT statement attempted to insert a duplicate key. For Trusted Oracle configured in DBMS MAC mode, you may see this message if a duplicate entry exists at a different level.
Action: Either remove the unique restriction or do not insert the key.

ORA-00017: session requested to set trace event
Cause: The current session was requested to set a trace event by another session.
Action: This is used internally; no action is required.

ORA-00018: maximum number of sessions exceeded
Cause: All session state objects are in use.
Action: Increase the value of the SESSIONS initialization parameter.

ORA-00019: maximum number of session licenses exceeded
Cause: All licenses are in use.
Action: Increase the value of the LICENSE MAX SESSIONS initialization parameter.

ORA-00020: maximum number of processes (string) exceeded
Cause: All process state objects are in use.
Action: Increase the value of the PROCESSES initialization parameter.

ORA-00021: session attached to some other process; cannot switch session
Cause: The user session is currently used by others.
Action: Do not switch to a session attached to some other process.

ORA-00022: invalid session ID; access denied
Cause: Either the session specified does not exist or the caller does not have the privilege to access it.
Action: Specify a valid session ID that you have privilege to access, that is either you own it or you have the CHANGE_USER privilege.

ORA-00023: session references process private memory; cannot detach session
Cause: An attempt was made to detach the current session when it contains references to process private memory.
Action: A session may contain references to process memory (PGA) if it has an open network connection, a very large context area, or operating system privileges. To allow the detach, it may be necessary to close the session's database links and/or cursors. Detaching a session with operating system privileges is always disallowed.

ORA-00024: logins from more than one process not allowed in single-process mode
Cause: Trying to login more than once from different processes for ORACLE started in single-process mode.
Action: Logoff from the other process.

ORA-00025: failed to allocate string
Cause: Out of memory.
Action: Restart with larger sga heap.

ORA-00026: missing or invalid session ID
Cause: Missing or invalid session ID string for ALTER SYSTEM KILL SESSION.
Action: Retry with a valid session ID.

ORA-00027: cannot kill current session
Cause: Attempted to use ALTER SYSTEM KILL SESSION to kill the current session.
Action: None

ORA-00028: your session has been killed
Cause: A privileged user has killed your session and you are no longer logged on to the database.
Action: Login again if you wish to continue working.

ORA-00029: session is not a user session
Cause: The session ID specified in an ALTER SYSTEM KILL SESSION command was not a user session (for example, recursive, etc.).
Action: Retry with a user session ID.

ORA-00030: User session ID does not exist.
Cause: The user session ID no longer exists, probably because the session was logged out.
Action: Use a valid session ID.

ORA-00031: session marked for kill
Cause: The session specified in an ALTER SYSTEM KILL SESSION command cannot be killed immediately (because it is rolling back or blocked on a network operation), but it has been marked for kill. This means it will be killed as soon as possible after its current uninterruptable operation is done.
Action: No action is required for the session to be killed, but further executions of the ALTER SYSTEM KILL SESSION command on this session may cause the session to be killed sooner.

ORA-00032: invalid session migration password
Cause: The session migration password specified in a session creation call was invalid (probably too long).
Action: Retry with a valid password (less than 30 chars).

ORA-00033: current session has empty migration password
Cause: An attempt was made to detach or clone the current session and it has an empty migration password. This is not allowed.
Action: Create the session with a non-empty migration password.

ORA-00034: cannot string in current PL/SQL session
Cause: An attempt was made to issue a commit or rollback from a PL/SQL object (procedure, function, package) in a session that has this disabled (by 'alter session disable commit in procedure')
Action: Enable commits from PL/SQL in this session, or do not attempt to use commit or rollback in PL/SQL when they are disabled in the current session.

ORA-00036: maximum number of recursive SQL levels (string) exceeded
Cause: An attempt was made to go more than the specified number of recursive SQL levels.
Action: Remove the recursive SQL, possibly a recursive trigger.

ORA-00037: cannot switch to a session belonging to a different server group
Cause: An attempt was made to switch to a session in a different server group. This is not allowed.
Action: Make sure the server switches to a session that belongs to its server group.

ORA-00038: Cannot create session: server group belongs to another user
Cause: An attempt was made to create a non-migratable session in a server group that is owned by a different user.
Action: A server group is owned by the first user who logs into a server in the server group in non-migratable mode. All subsequent non-migratable mode logins must be made by the user who owns the server group. To have a different user login in non-migratable mode, the ownership of the server group will have to be changed. This can be done by logging off all current sessions and detaching from all existing servers in the server group and then having the new user login to become the new owner.

ORA-00039: error during periodic action
Cause: An unexpected error occurred while executing a periodically invoked
Action: Check the error stack for detailed error information.

ORA-00044: timed_statistics must be TRUE when statistics_level is not BASIC
Cause: The user attempted to set timed_statistics to FALSE when statistics_level was not BASIC. timed_statistics is required to be TRUE to collect meaningful statistics when statistics_level is set to TYPICAL or ALL.
Action: Either set timed_statistics to TRUE or set statistics_level to BASIC.

ORA-00050: operating system error occurred while obtaining an enqueue
Cause: Could not obtain the operating system resources necessary to cover an oracle enqueue. This is normally the result of an operating system user quota that is too low.
Action: Look up the operating system error in your system documentation and perform the needed action.

ORA-00051: timeout occurred while waiting for a resource
Cause: Usually due to a dead instance.
Action: Check for any dead, unrecovered instances and recover them.

ORA-00052: maximum number of enqueue resources (string) exceeded

Cause: The block size specified was too small. Space for the system overhead is required.
Action: Specify a larger block size and retry the operation.

ORA-00213: cannot reuse control file; old file size stringstring required
Cause: To reuse a control file, it must be the same size as the one previously used.
Action: Either do not specify REUSE, or specify a matching combination of MAXDATAFILES, MAXLOGFILES, MAXLOGMEMBERS, MAXLOGHISTORY, and MAXINSTANCES clauses in the CREATE DATABASE or CREATE CONTROLFILE statement.

ORA-00214: control file 'string' version string inconsistent with file 'string' version string
Cause: An inconsistent set of control files, datafiles/logfiles, and redo files was used.
Action: Use a consistant set of control files, datafiles/logfiles, and redo log files. That is, all the files must be for the same database and from the same time period.

ORA-00215: must be at least one control file
Cause: No control file is specified or the control file specified does not exist.
Action: Specify at least one valid control file and retry the operation.

ORA-00216: control file could not be resized for migration from 8.0.2
Cause: The control file created by release 8.0.2 was missing some record types. These record types are automatically added by resizing the control file during mount. The resize has failed.
Action: Look in the alert log for the reason that the resize has failed. If indicated in the alert log, give the control file more space. Otherwise, use the CREATE CONTROLFILE script dumped to the trace file to create a new control file.

ORA-00217: control file could not be resized for new record types
Cause: The control file was missing some new record types supported by this release. These record types are automatically added by resizing the contol file during mount. The resize has failed.
Action: Look in the alert log for the reason that the resize has failed. If indicated in the alert log, give the control file more space. Otherwise, use the CREATE CONTROLFILE script dumped to the trace file to create a new control file.

ORA-00218: block size string of control file 'string' does not match DB_BLOCK_SIZE (string)
Cause: The block size as stored in the control file header is different from the value of the initialization parameter DB_BLOCK_SIZE. This might be due to an incorrect setting of DB_BLOCK_SIZE, or else might indicate that the control file has either been corrupted or belongs to a different database.
Action: Restore a good copy of the control file. If the control file is known to be clean set the DB_BLOCK_SIZE to match control file headers block size value.

ORA-00219: required control file size (string logical blocks) exceeds maximum allowable size (string logical blocks)
Cause: An invocation of CREATE DATABASE or CREATE CONTROLFILE was executed specifying a combination of parameters that would require the control file size in blocks to exceed the maximum allowable value.
Action: In the case of CREATE DATABASE or CREATE CONTROLFILE, use a different combination of MAXDATAFILES, MAXLOGFILES, MAXLOGMEMBERS, MAXLOGHISTORY, and MAXINSTANCES clauses.

ORA-00220: control file not mounted by first instance, check alert log for more info
Cause: The specified control file has a different mount ID than the other control files that are being mounted. This means that the first instance to mount the database did not use this control file.
Action: Find and install the correct control file.

ORA-00221: error on write to control file
Cause: An error occurred when writing to one or more of the control files.
Action: See accompanying messages.

ORA-00222: operation would reuse name of a currently mounted control file
Cause: The filename supplied as a parameter to the ALTER DATABASE BACKUP CONTROLFILE command or to cfileSetSnapshotName matches the name of the specified currently mounted control file.
Action: Retry the operation with a different filename.

ORA-00223: convert file is invalid or incorrect version
Cause: An Oracle7 to Oracle8 convert file contains invalid data or was created with an different version of the migration utility. This error can also be caused by incorrect ORACLE_HOME environment variable when ALTER DATABASE CONVERT command is issued.
Action: Use a correct version of the convert file or regenerate it with the migration utility. Make sure that the migration utility is the same version as the Oracle8 RDBMS executable and that the ORACLE_HOME environment variable is properly set.

ORA-00224: control file resize attempted with illegal record type (string)
Cause: An attempt was made to expand or shrink the control file by calling cfileResizeSection using an invalid value for the RECORD_TYPE parameter.
Action: Use a value for the RECORD_TYPE parameter that specifies a valid record type other than type 0 (valid range is 1-16).

ORA-00225: expected size string of control file differs from actual size string
Cause: The expected size of the control file as stored in its header was different than the actual operating system file size. This usually indicates that the control file was corrupted.
Action: Restore a good copy of the control file.

ORA-00226: operation disallowed while alternate control file open
Cause: The attempted operation could not be executed at this time because this process had an alternate control file open for fixed table access.
Action: Retry the operation after calling cfileUseCurrent.

ORA-00227: corrupt block detected in control file: (block string, # blocks string)
Cause: A block header corruption or checksum error was detected on reading the control file.
Action: Use the CREATE CONTROLFILE or RECOVER DATABASE USING BACKUP CONTROLFILE command.

ORA-00228: length of alternate control file name exceeds maximum of string
Cause: The specified filename, which was supplied as a parameter to cfileSetSnapshotName or cfileUseCopy, exceeds the maximum filename length for this operating system.
Action: Retry the operation with a shorter filename.

ORA-00229: operation disallowed: already hold snapshot control file enqueue
Cause: The attempted operation cannot be executed at this time because this process currently holds the snapshot control file enqueue.
Action: Retry the operation after calling cfileUseCurrent to release the snapshot control file enqueue.

ORA-00230: operation disallowed: snapshot control file enqueue unavailable
Cause: The attempted operation cannot be executed at this time because another process currently holds the snapshot control file enqueue.
Action: Retry the operation after the concurrent operation that is holding the snapshot control file enqueue terminates.

ORA-00231: snapshot control file has not been named
Cause: During an invocation of cfileMakeAndUseSnapshot or cfileUseSnapshot it was detected that no filename for the snapshot control file had previously been specified.
Action: Specify a name for the snapshot control file by calling cfileSetSnapshotName.

ORA-00232: snapshot control file is nonexistent, corrupt, or unreadable
Cause: The snapshot control file was found to be nonexistent, corrupt, or unreadable during an invocation of cfileUseSnapshot.
Action: Call cfileMakeAndUseSnapshot again (or for the first time).

ORA-00233: copy control file is corrupt or unreadable
Cause: The specified copy control file was found to be corrupt or unreadable during an invocation of cfileUseCopy.
Action: Before retrying cfileUseCopy, use the ALTER DATABASE BACKUP CONTROLFILE command and specify the same filename that was specified for cfileUseCopy.

ORA-00234: error in identifying or opening snapshot or copy control file
Cause: A snapshot or copy control file of the specified name could not be found or opened during an invocation of cfileUseSnapshot, cfileMakeAndUseSnapshot, or cfileUseCopy.
Action: Re-create the snapshot or copy control file using cfileMakeAndUseSnapshot or ALTER DATABASE BACKUP CONTROLFILE, respectively.

ORA-00235: control file read without a lock inconsistent due to concurrent update
Cause: Concurrent update activity on a control file caused a process to read inconsistent information from the control file without a lock.
Action: Retry the operation.

ORA-00236: snapshot operation disallowed: mounted control file is a backup
Cause: Attempting to invoke cfileSetSnapshotName, cfileMakeAndUseSnapshot, or cfileUseSnapshot when the currently mounted control file is a backup control file.
Action: Mount a current control file and retry the operation.

ORA-00237: snapshot operation disallowed: control file newly created
Cause: An attempt to invoke cfileMakeAndUseSnapshot with a currently mounted control file that was newly created with CREATE CONTROLFILE was made.
Action: Mount a current control file and retry the operation.

ORA-00238: operation would reuse a filename that is part of the database
Cause: The filename supplied as a parameter to the ALTER DATABASE BACKUP CONTROLFILE command or to cfileSetSnapshotName matches the name of a file that is currently part of the database.
Action: Retry the operation with a different filename.

ORA-00239: timeout waiting for control file enqueue: held by 'string' for more than string seconds
Cause: The specified process waited the maximum allowed time for the control file enqueue.
Action: Restart the blocking instance indicated in the incident trace file or reboot the blocking node.

ORA-00240: control file enqueue held for more than string seconds
Cause: The current process did not release the control file enqueue within the maximum allowed time.
Action: Reissue any commands that failed and contact Oracle Support Services with the incident information.

ORA-00250: archiver not started
Cause: An attempt was made to stop automatic archiving, but the archiver process was not running.
Action: No action required.

ORA-00251: LOG_ARCHIVE_DUPLEX_DEST cannot be the same destination as string string
Cause: The destination specified by the LOG_ARCHIVE_DUPLEX_DEST parameter is the same as the destination specified by an ALTER SYSTEM ARCHIVE LOG START TO command.
Action: Specify a different destination for parameter LOG_ARCHIVE_DUPLEX_DEST, or specify a different destination with the ALTER SYSTEM command.

ORA-00252: log string of thread string is empty, cannot archive
Cause: A log must be used for redo generation before it can be archived. The specified redo log was not been used since it was introduced to the database. However it is possible that instance death during a log switch left the log empty.
Action: Empty logs do not need to be archived. Do not attempt to archive the redo log file.

ORA-00253: character limit string exceeded by archive destination string string
Cause: The destination specified by an ALTER SYSTEM ARCHIVE LOG START TO command was too long.
Action: Retry the ALTER SYSTEM command using a string shorter than the limit specified in the error message.

ORA-00254: error in archive control string 'string'
Cause: The specified archive log location is invalid in the archive command or the LOG_ARCHIVE_DEST initialization parameter.
Action: Check the archive string used to make sure it refers to a valid online device.

ORA-00255: error archiving log string of thread string, sequence # string
Cause: An error occurred during archiving.
Action: Check the accompanying message stack for more detailed information. If the online log is corrupted, then the log can be cleared using the UNARCHIVED option. This will make any existing backups useless for recovery to any time after the log was created, but will allow the database to generate redo.

ORA-00256: cannot translate archive destination string string
Cause: The destination specified by an ALTER SYSTEM ARCHIVE LOG START TO command could not be translated.
Action: Check the accompanying message stack for more detailed information. Then, retry the ALTER SYSTEM command using a different string.

ORA-00257: archiver error. Connect internal only, until freed.
Cause: The archiver process received an error while trying to archive a redo log. If the problem is not resolved soon, the database will stop executing transactions. The most likely cause of this message is the destination device is out of space to store the redo log file.
Action: Check archiver trace file for a detailed description of the problem. Also verify that the device specified in the initialization parameter ARCHIVE_LOG_DEST is set up properly for archiving.

ORA-00258: manual archiving in NOARCHIVELOG mode must identify log
Cause: The database is in NOARCHIVELOG mode and a command to manually archive a log did not specify the log explicitly by sequence number, group number or filename.
Action: Specify log by filename, by group number or by thread and sequence number.

ORA-00259: log string of open instance string (thread string) is the current log, cannot archive
Cause: An attempt was made to archive the current log of an open thread. This is not allowed because the redo log file may still be in use for the generation of redo entries.
Action: Force a log switch in the instance where the thread is open. If no instances are open, open the database so that instance recovery can recover the thread.

ORA-00260: cannot find online log sequence string for thread string
Cause: The log sequence number supplied to the archival command does not match any of the online logs for the thread. The log might have been reused for another sequence number, it might have been dropped, the sequence number might be greater than the current log sequence number, or the thread might not have any logs.
Action: Check the ARCHIVE statement, then specify a valid log sequence number. Specify a valid log sequence number.

ORA-00261: log string of thread string is being archived or modified
Cause: The log is either being archived by another process or an administrative command is modifying the log. Operations that modify the log include clearing, adding a member, dropping a member, renaming a member, and dropping the log.
Action: Wait for the current operation to complete and try again.

ORA-00262: current log string of closed thread string cannot switch
Cause: The log cannot be cleared or manually archived because it is the current log of a closed thread, and it is not possible to switch logs so another log is current. All other logs for the thread need to be archived, or cleared, and cannot be reused.
Action: Archive another log in the same thread first, or complete the clearing. See attached errors for the reason the switch cannot be completed.

ORA-00263: there are no logs that need archiving for thread string
Cause: An attempt was made to manually archive the unarchived logs in this thread but no logs needed archiving.
Action: No action required.

ORA-00264: no recovery required
Cause: An attempt was made to perform media recovery on files that do not // need any type of recovery.
Action: Do not attempt to perform media recovery on the selected files. Check to see that the filenames were entered properly. If not, retry the command with the proper filenames.

ORA-00265: instance recovery required, cannot set ARCHIVELOG mode
Cause: The database either crashed or was shutdown with the ABORT option. Media recovery cannot be enabled because the online logs may not be sufficient to recover the current datafiles.
Action: Open the database and then enter the SHUTDOWN command with the NORMAL or IMMEDIATE option.

ORA-00266: name of archived log file needed
Cause: During media recovery, the name of an archived redo log file was requested, but no name was entered.
Action: Mount the correct redo log file and enter its name when it is requested.

ORA-00267: name of archived log file not needed
Cause: During media recovery, the name of an archived redo log file was entered, but no name was requested.
Action: Continue media recovery, but do not enter a new log name.

ORA-00268: specified log file does not exist 'string'
Cause: The given redo log file does not exist.
Action: Check the spelling and capitalization of the filename and retry the command.

ORA-00269: specified log file is part of thread string not string
Cause: The given redo log file is not part of the given thread
Action: Check that the thread of the redo log file matches the thread on the command line. If not, use a redo log file from the appropriate thread. Retry the command after correcting the error.

ORA-00270: error creating archive log string
Cause: An error was encountered when either creating or opening the destination file for archiving.
Action: Check that the archive destination is valid and that there is sufficient space on the destination device.

ORA-00271: there are no logs that need archiving
Cause: An attempt was made to archive the unarchived redo log files manually, but there are no files that need to be archived.
Action: No action required.

ORA-00272: error writing archive log string
Cause: An I/O error occurred while archiving a redo log file.
Action: Check that the output device is still available and correct any device errors that may have occurred. Also, make certain that sufficient space for archiving is available on the output device.

ORA-00273: media recovery of direct load data that was not logged
Cause: A media recovery session encountered a table that was loaded by the direct loader without logging any redo information. Some or all of the blocks in this table are now marked as corrupt.
Action: The table must be dropped or truncated so that the corrupted blocks can be reused. If a more recent backup of the file is available, try to recover this file to eliminate this error.

ORA-00274: illegal recovery option string
Cause: An illegal option was specified for a recovery command.
Action: Correct the syntax and retry the command.

ORA-00275: media recovery has already been started
Cause: An attempt was made to start a second media recovery operation in the same session.
Action: Complete or cancel the first media recovery session or start another session to perform media recovery.

ORA-00276: CHANGE keyword specified but no change number given
Cause: The CHANGE keyword was specified on the command line, but no change number was given.
Action: Retry the command using a valid change number after the CHANGE keyword.

ORA-00277: illegal option to the UNTIL recovery flag string
Cause: Only CANCEL, CHANGE, CONSISTENT and TIME can be used with the UNTIL keyword.
Action: Correct the syntax.

ORA-00278: log file 'string' no longer needed for this recovery
Cause: The specified redo log file is no longer needed for the current recovery.
Action: No action required. The archived redo log file may be removed from its current location to conserve disk space, if needed. However, the redo log file may still be required for another recovery session in the future.

ORA-00279: change string generated at string needed for thread string
Cause: The requested log is required to proceed with recovery.
Action: Please supply the requested log with "ALTER DATABASE RECOVER LOGFILE " or cancel recovery with "ALTER DATABASE RECOVER CANCEL".

ORA-00280: change string for thread string is in sequence #string
Cause: This message helps to locate the redo log file with the specified change number requested by other messages.
Action: Use the information provided in this message to specify the required archived redo log files for other errors.

ORA-00281: media recovery may not be performed using dispatcher
Cause: An attempt was made to use a dispatcher process for media recovery. Memory requirements disallow this recovery method.
Action: Connect to the instance via a dedicated server process to perform media recovery.

ORA-00282: UPI string call not supported, use ALTER DATABASE RECOVER
Cause: The given UPI call is no longer supported.
Action: Use the ALTER DATABASE RECOVER command for all recovery actions.

ORA-00283: recovery session canceled due to errors
Cause: An error during recovery was determined to be fatal enough to end the current recovery session.
Action: More specific messages will accompany this message. Refer to the other messages for the appropriate action.

ORA-00284: recovery session still in progress
Cause: An error during recovery was determined to be minor enough to allow the current recovery session to continue.
Action: More specific messages will accompany this message. Refer to the other messages for the appropriate action.

ORA-00285: TIME not given as a string constant
Cause: UNTIL TIME was not followed by a string constant for the time.
Action: Enter the time enclosed in single quotation marks.

ORA-00286: no members available, or no member contains valid data
Cause: None of the members of a redo log file group are available, or the available members do not contain complete data.
Action: If a member is temporarily offline, attempt to make it available. Make sure that the correct filenames are being used, especially if the redo log file is being accessed from a remote location.

ORA-00287: specified change number string not found in thread string
Cause: The given change number does not appear in any of the online redo logs for the given thread.
Action: Check the statement to make certain a valid change number is given. Perhaps try to use the NEXT option for archiving logs.

ORA-00288: to continue recovery type ALTER DATABASE RECOVER CONTINUE
Cause: During media recovery, a new log is not required but the continuation command is necessary to do a checkpoint and report errors.
Action: Type ALTER DATABASE RECOVER CONTINUE and recovery will resume.

ORA-00289: suggestion : string
Cause: This message reports the next redo log filename that is needed, according to the initialization parameters LOG_ARCHIVE_DEST and LOG_ARCHIVE_FORMAT. This message assumes that LOG_ARCHIVE_DEST and LOG_ARCHIVE_FORMAT are the same now as when the required redo log file was archived.
Action: Consider using this filename for the next log needed for recovery.

ORA-00290: operating system archival error occurred. See error below
Cause: While attempting to archive to a redo log file, the server encountered an unexpected operating system error.
Action: Correct the operating system error given in the messages and retry the operation. See also your operating system-specific Oracle documentation.

ORA-00291: numeric value required for PARALLEL option
Cause: A recovery command was specified incorrectly. The PARALLEL option must be followed by a numeric argument that specifies the degree of parallelism.
Action: Re-enter the command with a numeric argument specifying the degree of parallelism desired.

ORA-00292: parallel recovery feature not installed
Cause: A parallel recovery was requested when the parallel recovery option is not installed.
Action: Delete the PARALLEL clause from the RECOVER command. Also, delete the RECOVERY_PARALLELISM parameter in the initialization file.

ORA-00293: control file out of sync with redo log
Cause: The redo log file and control file are out of sync because a non-current controle file was specified when the instance was started.
Action: Retry the RECOVER command using the current control file, or retry the RECOVER command using the USING BACKUP CONTROLFILE clause.

ORA-00294: invalid archivelog format specifier 'string'
Cause: An invalid format specifier was found in the LOG_ARCHIVE_FORMAT initialization parameter. The only characters permitted following the % symbol are s, S, t, and T.
Action: Correct the initialization file and re-start the instance.

ORA-00295: datafile/tempfile number string is invalid, must be between 1 and string
Cause: An invalid file number was specified.
Action: Specify a valid datafile or tempfile number and retry the operation.

ORA-00296: maximum number of files (string) exceeded for RECOVER DATAFILE LIST
Cause: The RECOVER DATAFILE LIST command specified more datafiles than are allowed by the DB_FILES initialization parameter. This error occurs when doing recovery with Recovery Manager, and the instance has been started with a DB_FILES parameter specifying fewer datafiles than recovery manager needs to recover to satisfy the user's RECOVER command.
Action: Re-start the instance with a higher value for DB_FILES.

ORA-00297: must specify RECOVER DATAFILE LIST before RECOVER DATAFILE START
Cause: The RECOVER DATAFILE START command was issued, but no RECOVER DATAFILE LIST commands had been issued. This only happens when doing recovery with Recovery Manager, and is an internal error in Recovery Manager, because Recovery Manager should always issue RECOVER DATAFILE LIST before RECOVER DATAFILE START.
Action: Contact customer support

ORA-00298: Missing or invalid attribute value
Cause: A non-zero integer value is required when the following keyword attributes are specified: TIMEOUT, EXPIRE, DELAY, NEXT
Action: Correct the syntax and retry the command.

ORA-00299: must use file-level media recovery on data file string
Cause: The control file does not contain an entry for this file, so block media recovery cannot be done.
Action: Restore the data file and perform file-level media recovery.

ORA-00300: illegal redo log block size string specified - exceeds limit of string
Cause: The specified block size of the redo log is greater than the maximum block size for the operating system.
Action: Create the redo log on a device with a smaller block size

ORA-00301: error in adding log file 'string' - file cannot be created
Cause: The creation of the redo log file failed
Action: Check: 1) there is enough storage space on the device 2) the name of the file is valid 3) the device is online 4) an IO error occurred Also, it is possible REUSE was specified on the command line and a file of the incorrect size exists. Either do not specify REUSE or use a file of the correct size.

ORA-00302: limit of string logs exceeded
Cause: The maximum number of redo log files has been exceeded.
Action: Use the CREATE CONTROLFILE command with a larger value for MAXLOGFILES if the compatibility is lower than 10.2.0. Otherwise, allocate more storage space for the control file.

ORA-00303: cannot process Parallel Redo
Cause: A redo log containing Parallel Redo has been detected. The current Oracle release cannot process this format of redo.
Action: Use a later release that supports Parallel Redo. to process this log.

ORA-00304: requested INSTANCE_NUMBER is busy
Cause: An instance tried to start by using a value of the initialization parameter INSTANCE_NUMBER that is already in use.
Action: Either a) specify another INSTANCE_NUMBER, b) shut down the running instance with this number c) wait for instance recovery to complete on the instance with this number.

ORA-00305: log string of thread string inconsistent; belongs to another database
Cause: The database ID in the redo log file does not match the database ID in the control file. This redo log file is not from the current database.
Action: Specify the correct redo log file, then retry the operation.

Cause: Starting this instance would exceed the maximum number of instances allowed for this database. This message occurs only with STARTUP shared and multiple instances.
Action: You cannot start more than the lower of a) port-specific limit as to the number of instances b) the number of instances specified at create-database time

ORA-00307: requested INSTANCE_NUMBER out of range, maximum is string
Cause: The initialization parameter INSTANCE_NUMBER specified a number that was out of range.
Action: Change INSTANCE_NUMBER to a valid range and restart the instance. The minimum value is one and the maximum value is the lower of the operating system-specific maximum or the MAXINSTANCES option specified in the CREATE DATABASE statement. See also your operating system-specific Oracle documentation.

ORA-00308: cannot open archived log 'string'
Cause: The system cannot access a required archived redo log file.
Action: Check that the off line log exists, the storage device is online, and the archived file is in the correct location. Then attempt to continue recovery or restart the recovery session.

ORA-00309: log belongs to wrong database
Cause: The system cannot access the archived redo log because it belongs to another database.
Action: Specify the correct redo log file, then retry the operation.

ORA-00310: archived log contains sequence string; sequence string required

Cause: The log was written by incompatible version of Oracle.
Action: Recover the database with the compatible software, shut it down cleanly, then restart with current software.

ORA-00332: archived log is too small - may be incompletely archived
Cause: The log is smaller than the space allocated in it. May be the result of a shutdown abort while it was being written by the archiver.
Action: Get a complete version of this log and use it for recovery. There should either be an online version of it or a copy that was successfully archived.

ORA-00333: redo log read error block string count string
Cause: An IO error occurred while reading the log described in the accompanying error.
Action: Restore accessibility to file, or get another copy of the file.

ORA-00334: archived log: 'string'
Cause: Reporting filename for details of another error
Action: See associated error messages

ORA-00335: online log string: No log with this number, log does not exist
Cause: Reporting filename for details of another error
Action: See associated error messages

ORA-00336: log file size string blocks is less than minimum string blocks
Cause: The log file size as specified in create database is too small.
Action: Increase the log file size.

ORA-00337: log file 'string' does not exist and no size specified
Cause: An attempt to add a log found neither an existing file nor a size for creating the file.
Action: Specify a size for the log file.

ORA-00338: log string of thread string is more recent than control file
Cause: The control file change sequence number in the log file is greater than the number in the control file. This implies that the wrong control file is being used. Note that repeatedly causing this error can make it stop happening without correcting the real problem. Every attempt to open the database will advance the control file change sequence number until it is great enough.
Action: Use the current control file or do backup control file recovery to make the control file current. Be sure to follow all restrictions on doing a backup control file recovery.

ORA-00339: archived log does not contain any redo
Cause: The archived log is not the correct log. It is a copy of a log file that has never been used for redo generation, or was an online log being prepared to be the current log.
Action: Restore the correct log file.

ORA-00340: IO error processing online log string of thread string
Cause: An IO error occurred on the named online log.
Action: Restore accessibility to file, or restore file from backup.

ORA-00341: log string of thread string, wrong log # string in header
Cause: The internal information in an online log file does not match the control file.
Action: Restore correct file or reset logs.

ORA-00342: archived log does not have expected resetlogs SCN string
Cause: Recovery was given a log that does not belong to current incarnation or one of the parent incarnation. There should be another log that contains the correct redo.
Action: Supply the correct log file.

ORA-00344: unable to re-create online log 'string'
Cause: An I/O failure occurred when attempting to re-create an online as part of either ALTER DATABASE OPEN RESETLOGS or ALTER DATABASE CLEAR LOGFILE command.
Action: Correct the file/device as indicated by accompanying errors.

ORA-00345: redo log write error block string count string
Cause: An IO error has occurred while writing the log
Action: Correct the cause of the error, and then restart the system. If the log is lost, apply media/incomplete recovery.

ORA-00346: log member marked as STALE and closed
Cause: A log file member was no longer complete.
Action: Correct the underlying problem by referring to the other error messages found with this one.

ORA-00347: log string of thread string, expected block size string doesn't match string
Cause: On header read the blocksize indicated in the control file did not match the blocksize contained in the log file.
Action: Restore correct file or reset logs.

ORA-00348: single-process redo failure. Must abort instance
Cause: A failure occurred during a critical portion of the log code during single process operation. This error does not occur during normal multi-process operation.
Action: Shutdown abort and warmstart the database.

ORA-00349: failure obtaining block size for 'string'
Cause: The operating system was unable to determine the blocksize for the given filename.
Action: Consult the accompanying error message, and correct the device or specify another filename.

ORA-00350: log string of instance string (thread string) needs to be archived
Cause: The command cannot be done because the log has not been archived, and media recovery has been enabled.
Action: Archive the log or disable media recovery. If the command supports an UNARCHIVED option then it can be used. However this may result in making backups unuseable, and forcing the drop of some offline files.

ORA-00351: recover-to time invalid
Cause: The time specified in a recover-until statement must be after January 1st 1988.
Action: Specify a time after January 1st 1988.

ORA-00352: all logs for thread string need to be archived - cannot enable
Cause: Attempting to enable a thread with all logs needing to be archived, and media recovery has been enabled. There is no log that can be made the new current log for the thread.
Action: Archive a log for the thread or disable media recovery.

ORA-00353: log corruption near block string change string time string
Cause: Some type of redo log corruption has been discovered. This error describes the location of the corruption. Accompanying errors describe the type of corruption.
Action: Do recovery with a good version of the log or do incomplete recovery up to the indicated change or time.

ORA-00354: corrupt redo log block header
Cause: The block header on the redo block indicated by the accompanying error, is not reasonable.
Action: Do recovery with a good version of the log or do time based recovery up to the indicated time. If this happens when archiving, archiving of the problem log can be skipped by clearing the log with the UNARCHIVED option. This must be followed by a backup of every datafile to insure recoverability of the database.

ORA-00355: change numbers out of order
Cause: A change number found in the redo log is lower than a previously encountered change number. The log is corrupted in some way. The corruption may be at the earlier change or at this one.
Action: Do recovery with a good version of the log or do time based recovery up to the indicated time.

ORA-00356: inconsistent lengths in change description
Cause: A change record in the redo log contains lengths that do not add up to a consistent value. The log is corrupted in some way.
Action: Do recovery with a good version of the log or do time based recovery up to the indicated time.

ORA-00357: too many members specified for log file, the maximum is string
Cause: An add logfile or add logfile member command would result in a log with too many members. The number of members is set when the database is created.
Action: Use fewer log file members.

ORA-00358: Too many file members specified, the maximum is string
Cause: A create or alter statement specified too many members in a parenthesised file list.
Action: Specify a number of file members that is within the port-defined limit.

ORA-00359: logfile group string does not exist
Cause: An add logfile member or drop logfile request specified a logfile group number that does not exist.
Action: Check the configuration of the log files and reissue the command.

ORA-00360: not a logfile member: string
Cause: A filename was given to drop logfile member that is not a part of the database, or which is a data file.
Action: Supply a valid logfile member name.

ORA-00361: cannot remove last log member string for group string
Cause: An attempt has been made to remove the last member of a log file group.
Action: If desired, delete the entire log, by using DROP LOGFILE.

ORA-00362: member is required to form a valid logfile in group string
Cause: A request to drop a logfile member was denied because it would remove data required to form a complete logfile.
Action: If desired, delete the entire log (after archiving if required), by using DROP LOGFILE;

ORA-00363: log is not the archived version
Cause: d by failing to list the current log of an enabled thread in a CREATE CONTROLFILE command.
Action: Find the archived version of the log and supply its name. If this is media recovery immediately following a CREATE CONTROLFILE, be sure the current log for this thread was included.

ORA-00364: cannot write header to new log member
Cause: An i/o error occurred when attempting to write the header to a log member that is being added to an existing group.
Action: See accompanying errors. Fix problem or use another file.

ORA-00365: the specified log is not the correct next log
Cause: The specified log failed to pass checks to ensure it corresponds to the log that was just applied. This is probably the result of using a log that was generated against a cold backup image of the database.
Action: Find the log that was generated by this copy of the database and give that filename to recovery.

ORA-00366: log string of thread string, checksum error in the file header
Cause: The file header for the redo log contains a checksum that does not match the value calculated from the file header as read from disk. This means the file header is corrupted
Action: Find and install correct version of log or reset logs.

ORA-00367: checksum error in log file header
Cause: The file header for the redo log contains a checksum that does not match the value calculated from the file header as read from disk. This means the file header is corrupted
Action: Find the correct file and try again.

ORA-00368: checksum error in redo log block
Cause: The redo block indicated by the accompanying error, is not vaild. It has a checksum that does not match the block contents.
Action: Restore correct file or reset logs.

ORA-00369: Current log of thread string not useable and other log being cleared
Cause: Attempt to open thread failed because it is necessary to switch redo generation to another online log, but all the other logs are being cleared or need to be archived before they can be used.
Action: If the ALTER DATABASE CLEAR LOGFILE command is still active then wait for it to complete. Otherwise reissue the CLEAR command. If there are other online logs for the thread, that are not being cleared, then archive the logs.

ORA-00370: potential deadlock during kcbchange operation
Cause: Error code used internally by software. Should never be reported
Action: Treat as internal error. See error 600.

ORA-00371: not enough shared pool memory, should be atleast string bytes
Cause: Init.ora parameter shared_pool_size is too small
Action: Increase the parameter value

ORA-00372: file string cannot be modified at this time
Cause: attempting to modify the contents of a file that cannot be modified. The file is most likely part of a read only tablespace but may be in the process of going offline, or the database may be in the process of closing.
Action: check the status of the file and its tablespace

ORA-00373: online log version string incompatible with ORACLE version string
Cause: The online log was written by incompatible version of Oracle. Can occur when the log file was created by either a new or older version of Oracle.
Action: Recover the database with the compatible software, shut it down cleanly, then restart with current software.

ORA-00374: parameter db_block_size = string invalid ; must be a multiple of string in the range [string..string]
Cause: invalid value for db_block_size parameter
Action: adjust parameter and restart

ORA-00376: file string cannot be read at this time
Cause: attempting to read from a file that is not readable. Most likely the file is offline.
Action: Check the state of the file. Bring it online

ORA-00377: Frequent backups of file string causing write operation to stall
Cause: Backups are occurring too frequently on this file. Each time a new backup is started for a file, any writes which have been previously issued (but not completed) have to be re-issued. If hot backups are started very, very frequently, it is possible that some writes will be re-issued repeatedly and never complete.
Action: Increase the interval between begin hot-backup commands for this file.

ORA-00378: buffer pools cannot be created as specified
Cause: Either the number of buffers or the number of lru latches is too small to satisfy the specified buffer pool configuration.
Action: Either increase the number of buffers and/or number of lru latches or configure smaller buffer pools.

ORA-00379: no free buffers available in buffer pool string for block size stringK
Cause: All buffers in the specified buffer pool for the specified block size are in use and no free buffers are available.
Action: Increase the number of buffers in the specified pool for the specified block size

ORA-00380: cannot specify db_stringk_cache_size since stringK is the standard block size
Cause: User specified the parameter db_nk_cache_size (where n is one of 2,4,8,16,32), while the standard block size for this database is equal to n Kbytes. This is illegal.
Action: Specify the standard block size cache using db_cache_size (DEFAULT pool) (and db_recycle_cache_size, db_keep_cache_size if additional buffer pools are required). Do NOT use the corresponding db_nk_cache_size parameter for the standard block size.

ORA-00381: cannot use both new and old parameters for buffer cache size specification
Cause: User specified one or more of { db_cache_size , db_recycle_cache_size, db_keep_cache_size, db_nk_cache_size (where n is one of 2,4,8,16,32), db_cache_advice } AND one or more of { db_block_buffers, buffer_pool_keep , buffer_pool_recycle }. This is illegal.
Action: Use EITHER the old (pre-Oracle_8.2) parameters OR the new ones. Don't specify both. If old size parameters are specified in the parameter file, you may want to replace them with new parameters since the new parameters can be modified dynamically and allow you to configure additional caches for additional block sizes. Cache advisory can only be enabled with the new cache parameters.

ORA-00382: string not a valid block size, valid range [string..string]
Cause: User specified a value for db_nk_cache_size where n is one of {2, 4, 8, 16, 32}, but nk is not a valid block size for this platform.
Action: Remove corresponding parameter from the "init.ora" file and restart the instance.

ORA-00383: DEFAULT cache for blocksize string cannot be reduced to zero
Cause: User attempted to reduce db_cache_size to zero, or attempted to to reduce db_K_cache_size to zero while there were still online tablespaces with blocksize K. Note that since the SYSTEM tablespace cannot be taken offline, it is always illegal to set db_cache_size to zero.
Action: Offline any tablespaces with the corresponding blocksize and then perform the operation again.

ORA-00384: Insufficient memory to grow cache
Cause: The system could not allocate sufficient memory to grow the cache to the specified size.
Action: Attempt a smaller increase in the value of the parameter.

ORA-00385: cannot enable Very Large Memory with new buffer cache parameters
Cause: User specified one or more of { db_cache_size , db_recycle_cache_size, db_keep_cache_size, db_nk_cache_size (where n is one of 2,4,8,16,32) } AND use_indirect_data_buffers is set to TRUE. This is illegal.
Action: Very Large Memory can only be enabled with the old (pre-Oracle_8.2) parameters.

ORA-00386: use_indirect_data_buffers not supported
Cause: The system could not allocate sufficient memory to grow the cache to the specified size.
Action: Attempt a smaller increase in the value of the parameter.

ORA-00390: log string of thread string is being cleared, cannot become current log
Cause: An attempt to switch to a new online log for the redo thread failed because no reusable log could be found. This log is being cleared and will be useable when the clearing completes. The command that began the clearing may have terminated without completing the clearing.
Action: If the clear command is still executing then wait for its completion. If it terminated then reissue the clear command, or drop the log.

ORA-00391: All threads must switch to new log format at the same time
Cause: An attempt to switch the current log of a single thread is not allowed because the compatiblity requirements force a new log format version number. When changing log formats, all threads must switch to the new format at the same time.
Action: Open the database to cause the coordinated log switch. If that is not possible then return to the same software version and compatibility setting last used to open the database.

ORA-00392: log string of thread string is being cleared, operation not allowed
Cause: An operation encountered this online log in the middle of being cleared. The command that began the clearing may have terminated without completing the clearing.
Action: If the clear command is still executing then wait for its completion. If it terminated then reissue the clear command, or drop the log.

ORA-00393: log string of thread string is needed for recovery of offline datafiles
Cause: Log cannot be cleared because the redo in it is needed to recover offline datafiles. It has not been archived so there is no other copy available. If the log is cleared the tablespaces containing the files will have to be dropped.
Action: Archive the log then repeat the clear command. If archiving is not possible, and dropping the tablespaces is acceptible, then add the clause UNRECOVERABLE DATAFILE at the end of the clear command.

ORA-00394: online log reused while attempting to archive it
Cause: It has been detected that an online log that is being archived has been reused
Action: Cannot archive the logfile anymore since it has been overwritten

ORA-00395: online logs for the clone database must be renamed
Cause: A clone database open forces logfile renaming to avoid overwriting the primary logfiles
Action: Rename the logfiles manually or using the log_file_name_convert initialization parameter

ORA-00396: error string required fallback to single-pass recovery
Cause: The indicated error caused two-pass instance or crash recovery to fail. Recovery was retried with an alternate (slower) method to avoid the error.
Action: Correct the cause of the indicated error (also recorded) so that future instance or crash recovery can succeed with the two-pass algorithm. This usually requires making more main memory available to the recovery process.

ORA-00397: instance recovery process terminated with error
Cause: The foreground process doing instance recovery died.
Action: Check the foreground trace file for the cause of recovery failure.

ORA-00398: abort thread recovery due to reconfiguration
Cause: Global enqueue service reconfiguration occurred during instance/crash recovery.
Action: This is used internally, no action is required.

ORA-00399: corrupt change description in redo log
Cause: A change vector in the redo log failed validation checks.
Action: Do recovery with a good version of the log or do time based recovery up to the indicated time.

ORA-00400: invalid release value string for parameter string
Cause: The release level given for the specified init parameter is invalid.
Action: Correct the parameter value in the parameter file and retry.

ORA-00401: the value for parameter string is not supported by this release
Cause: The value specified cannot be supported by this release of the software.
Action: Choose an appropriate value, or remove the parameter value to use the default value.

ORA-00402: database changes by release string cannot be used by release string
Cause: Changes have been made to the database that require a newer software release or that violate the compatibility parameters.
Action: Use a version of the software that can understand the changes or relax the compatibility requirements in the init file.

ORA-00403: string (string) is not the same as other instances (string)
Cause: Another instance has set the compatible or compatible no recovery parameters differently than this instance.
Action: Change the parameters of the current instance to match other instances already running.

ORA-00404: Convert file not found: 'string'
Cause: The file used for converting the database from V7 to V8 could not be found.
Action: Verify that the migration process has been started on this database and that the convert filename is accessable.

ORA-00405: compatibility type "string"
Cause: Reporting a type associated with another error.
Action: See accompanying error

ORA-00406: COMPATIBLE parameter needs to be string or greater
Cause: The COMPATIBLE initialization parameter is not high enough to allow the operation. Allowing the command would make the database incompatible with the release specified by the current COMPATIBLE parameter.
Action: Shutdown and startup with a higher compatibility setting.

ORA-00407: rolling upgrade from release string.string to string.string is not allowed
Cause: Another instance executing software at a different point release already has the database mounted.
Action: Shutdown all instances then startup with the new software.

ORA-00408: parameter string is set to TRUE
Cause: Reporting the parameter that resulted in the compatibility error.
Action: Shutdown and startup with a higher compatibility setting.

ORA-00409: COMPATIBLE needs to be string or higher to use AUTO SEGMENT SPACE MANAGEMENT
Cause: This is due to migrating from an older release of Oracle with tablespaces created using AUTO SEGMENT SPACE MANAGEMENT. To open the database, the COMPATIBLE parameter needs to be set to the specified value.
Action: Shutdown and startup with the specified compatibility setting.

ORA-00437: ORACLE feature is not licensed. Contact Oracle Corp. for assistance
Cause: ORACLE feature is not licensed.
Action: Contact ORACLE for assistance.

Cause: The database name in the control file does not match your database name.
Action: Either find the correct control file or change your database name.

ORA-01104: number of control files (string) does not equal string
Cause: The number of control files used by this instance disagrees with the number of control files in an existing instance.
Action: Check to make sure that all control files are listed.

ORA-01105: mount is incompatible with mounts by other instances
Cause: An attempt to mount the database discovered that another instance mounted a database by the same name, but the mount is not compatible. Additional errors are reported explaining why.
Action: See accompanying errors.

ORA-01106: database must be closed before dismounting
Cause: Obvious
Action: None

ORA-01107: database must be mounted for media recovery
Cause: An attempt to perform media recovery was made but the database is not mounted.
Action: Mount the database.

ORA-01108: file string is in backup or media recovery

Cause: Attempting to drop a datafile when it is online
Action: Take file offline before dropping.

ORA-01121: cannot rename database file string - file is in use or recovery
Cause: Attempted to use ALTER DATABASE RENAME to rename a datafile that is online in an open instance or is being recovered.
Action: Close database in all instances and end all recovery sessions.

ORA-01122: database file string failed verification check
Cause: The information in this file is inconsistent with information from the control file. See accompanying message for reason.
Action: Make certain that the db files and control files are the correct files for this database.

ORA-01123: cannot start online backup; media recovery not enabled
Cause: An attempt to start backup of an on-line tablespace failed because media recovery is not enabled.
Action: Enable media recovery and retry this operation.

ORA-01124: cannot recover data file string - file is in use or recovery
Cause: An attempt to do media recovery found that the file was not available for recovery. Either it is online and the database is open in some instance, or another process is curently doing media recovery on the file.
Action: Do not do media recovery.

ORA-01125: cannot disable media recovery - file string has online backup set
Cause: An attempt to disable media recovery found that an online backup is still in progress.
Action: End the backup of the offending tablespace and retry this command.

ORA-01126: database must be mounted in this instance and not open in any instance
Cause: Obvious
Action: None

ORA-01127: database name 'string' exceeds size limit of string characters
Cause: Obvious
Action: None

ORA-01128: cannot start online backup - file string is offline
Cause: An attempt to start an online backup found that one of the files is offline.
Action: Bring the offending files online and retry this command or do a cold backup.

ORA-01129: user's default or temporary tablespace does not exist
Cause: The user's default or temporary tablespace was dropped.
Action: Reassign the default or temporary tablespace.

ORA-01135: file string accessed for DML/query is offline
Cause: Attempted to access a data file that is offline
Action: Bring the data file back online

ORA-01136: specified size of file string (string blocks) is less than original size of string blocks
Cause: A file size was specified in the AS clause of ALTER DATABASE CREATE DATAFILE, and the size was smaller the the size needed
Action: Create the file with a larger size.

ORA-01137: data file string is still in the middle of going offline
Cause: It was not possible to get the lock for a file that is offline when attempting to bring it online. The most likely cause is that the lock is still held by the instance that is took it offline.
Action: Wait a bit and try to online the file again.

ORA-01138: database must either be open in this instance or not at all
Cause: The requested operation can not be done when the database is mounted but not open in this instance, and another instance has the database open.
Action: Execute the operation in an open instance, open the datbase in this instance, or close the database in the other instances.

ORA-01139: RESETLOGS option only valid after an incomplete database recovery
Cause: The RESETLOGS option was given in ALTER DATABASE OPEN, but there has been no incomplete recovery session.
Action: Retry the ALTER DATABASE OPEN without specifying RESETLOGS

ORA-01140: cannot end online backup - all files are offline or readonly
Cause: All the files were found to be offline or readonly when attempting to end an online backup.
Action: None. Online backup does not need to be ended for this tablespace.

ORA-01141: error renaming data file string - new file 'string' not found
Cause: An attempt to change a data file's name in the control file failed because no file was found with the new name.
Action: Make sure that the data file has been properly renamed by the operating system and retry.

ORA-01142: cannot end online backup - none of the files are in backup
Cause: None of the files were found to be in online backup when attempting to end an online backup.
Action: None. Online backup does not need to be ended for this tablespace.

ORA-01143: cannot disable media recovery - file string needs media recovery
Cause: An attempt to disable media recovery found a file that needs media recovery, thus media recovery cannot be disabled.
Action: Recover the offending file or drop the tablespace it belongs to and retry this command.

ORA-01144: File size (string blocks) exceeds maximum of string blocks
Cause: Specified file size is larger than maximum allowable size value.
Action: Specify a smaller size.

ORA-01145: offline immediate disallowed unless media recovery enabled
Cause: ALTER TABLESPACE ... OFFLINE IMMEDIATE or ALTER DATABASE DATAFILE ... OFFLINE is only allowed if database is in ARCHIVELOG mode.
Action: Take tablespace offline normally or shutdown abort. Reconsider your backup strategy. You could do this if you were archiving your logs.

ORA-01146: cannot start online backup - file string is already in backup
Cause: When starting an online backup it was noticed that an online backup was already started for one of the data files.
Action: End the first backup before beginning another.

ORA-01147: SYSTEM tablespace file string is offline
Cause: A file belonging to the SYSTEM tablespace has been marked offline by the DBA. The database cannot be started until all SYSTEM tablespace files are online and openable.
Action: Bring the file online.

ORA-01148: cannot refresh file size for datafile string
Cause: An operating system or device error occurred when retrieving the file's size. The device on which the file resides may have been offline.
Action: Restore access to the device.

ORA-01149: cannot shutdown - file string has online backup set
Cause: An attempt to shutdown normally found that an online backup is still in progress.
Action: End the backup of the offending tablespace and retry this command.

ORA-01150: cannot prevent writes - file string has online backup set
Cause: An attempt to make a tablespace read only or offline normal found that an online backup is still in progress. It will be necessary to write the file header to end the backup, but that would not be allowed if this command succeeded.
Action: End the backup of the offending tablespace and retry this command.

ORA-01151: use media recovery to recover block, restore backup if needed
Cause: Error 1172 occurred.
Action: This is additional information for error 1172.

ORA-01152: file string was not restored from a sufficiently old backup
Cause: An incomplete recovery session was started, but an insufficient number of logs were applied to make the database consistent. This file is still in the future of the last log applied. The most likely cause of this error is forgetting to restore the file from a backup before doing incomplete recovery.
Action: Either apply more logs until the database is consistent or restore the database file from an older backup and repeat recovery.

ORA-01153: an incompatible media recovery is active
Cause: Attempted to start an incompatible media recovery or open resetlogs during media recovery or RMAN backup . Media recovery sessions are incompatible if they attempt to recover the same data file. Incomplete media recovery or open resetlogs is incompatible with any media recovery. Backup or restore by RMAN is incompatible with open resetlogs
Action: Complete or cancel the other media recovery session or RMAN backup

ORA-01154: database busy. Open, close, mount, and dismount not allowed now
Cause: Some operation is in progress that expects the opened/mounted state of this instance to remain the same.
Action: Wait for the operation to complete then retry. If attempting to do a shutdown, SHUTDOWN ABORT will work. If this is a shutdown of a standby database that is operating in NO DATA LOSS mode, you must shutdown the primary database first.

ORA-01155: the database is being opened, closed, mounted or dismounted
Cause: The requested operation needs the instance to be in a particular state but the state is being changed.
Action: Wait for the open, close, mount, or dismount to complete then retry the operation. If necessary, a SHUTDOWN ABORT will always work.

ORA-01156: recovery in progress may need access to files
Cause: Either media recovery or instance recovery is in progress. It may need the files this operation is being applied to.
Action: Wait for recovery to complete.

ORA-01157: cannot identify/lock data file string - see DBWR trace file
Cause: The background process was either unable to find one of the data files or failed to lock it because the file was already in use. The database will prohibit access to this file but other files will be unaffected. However the first instance to open the database will need to access all online data files. Accompanying error from the operating system describes why the file could not be identified.
Action: Have operating system make file available to database. Then either open the database or do ALTER SYSTEM CHECK DATAFILES.

ORA-01158: database string already mounted
Cause: Another instance has a database by this name mounted.
Action: Find which instance is still running. Perhaps you have not lost the control files after all.

ORA-01159: file is not from same database as previous files - wrong database id
Cause: Not all of the files specified in CREATE CONTROLFILE are from the same database. The database ID of this file does not match that from the first file specified.
Action: Please double check the list of files provided to the CREATE

ORA-01160: file is not a string
Cause: The named file in the DATAFILE or LOGFILE section of the CREATE CONTROLFILE command does not appear to be as stated.
Action: Please double check the mentioned file.

ORA-01161: database name string in file header does not match given name of string
Cause: The database name given at the command line does not match the database name found in the file header.
Action: Chance are good that the database name specified at the command line is incorrect. Resolve the descepency, and resubmit the command. If you are attempting to change the database name, be sure to use the SET DATABASE option.

ORA-01162: block size string in file header does not match configured block sizes
Cause: CREATE CONTROLFILE discovered that the block size for this file is incompatible with any of the configured cache blocksizes in the INIT.ORA file.
Action: Configure the appropriate cache for this block size using one of the various (db_2k_cache_size, db_4k_cache_size, db_8k_cache_size, db_16k_cache_size, db_32K_cache_size) parameters.

ORA-01163: SIZE clause indicates string (blocks), but should match header string
Cause: The size specified in bytes in the SIZE clause of the CREATE CONTROLFILE statement does not equate to the number of blocks recorded in the header.
Action: Specify the correct filename and size ( in bytes ).

ORA-01164: MAXLOGFILES may not exceed string
Cause: MAXLOGFILES specified on the command line too large.
Action: Resubmit the command with a smaller MAXLOGFILES

ORA-01165: MAXDATAFILES may not exceed string
Cause: MAXDATAFILES specified on the command line too large.
Action: Resubmit the command with a smaller MAXDATAFILES

ORA-01166: file number string is larger than string (string)
Cause: File mentioned in CREATE CONTROLFILE has a file number which is larger than that specified for MAXDATAFILES or MAXLOGFILES.
Action: Increase the maximum specified on the command line.

ORA-01167: two files are the same file/group number or the same file
Cause: There is an overlap of file numbers in the files specified on the command line or the same file is specified twice. If they are not the exact same file then one is likely to be a backup of the other. If they are two members of the same log they must be specified together in a group file spec. This message will also appear if the same control file appears more than once in the control_files parameter in the init.ora file. If this happens, check for additional error messages.
Action: Confirm that the file mentioned is not a repeat of a file already mentioned in the command. If they are different files then omit the earlier backup. If they are members of the same log, insure they are in the same group file specification. If this message appears because of a duplicate control file, check the control_files parameter in the init.ora file and see if a file is specified more than once. If all files names appear to be unique, check to make sure that the actual control files themselves are unique. For example, in UNIX check for a symbolic or a hard link to another control file in the list.

ORA-01168: physical block size string does not match size string of other members
Cause: The file is located on a device with a different physical block size than the other members in the group
Action: Use a physical device with matching block size.

ORA-01169: DATAFILE number 1 not found. Must be present
Cause: Datafile number 1 was not specified in a CREATE CONTROLFILE command.
Action: Locate datafile number 1 and resubmit the CREATE CONTROLFILE command.

ORA-01170: file not found 'string'
Cause: ALL datafiles and, if NORESETLOGS, ALL logfiles MUST be accessible by the process for CREATE CONTROLFILE.
Action: The file specified probably contains a typing error. Double check command and the existance of all files and then resubmit.

ORA-01171: datafile string going offline due to error advancing checkpoint
Cause: The checkpoint in the file header could not be advanced. See accompanying errors for the reason. The datafile will be taken offline the same as for a write error of a data block.
Action: See accompanying errors for details. Restore access to the file, do media recovery, and bring it back online.

ORA-01172: recovery of thread string stuck at block string of file string
Cause: Crash recovery or instance recovery could not apply a change to a block because it was not the next change. This can happen if the block was corrupted and then repaired during recovery.
Action: Do a RECOVER DATAFILE for the file containing the block. If this does not resolve the problem then restore the file from a backup and recover it.

ORA-01173: data dictionary indicates missing data file from system tablespace
Cause: Either the database has been recovered to a point in time in the future of the control file or a datafile from the system tablespace was omitted from the create control file command previously issued.
Action: For the former problem you need to recover the database from a more recent control file. For the latter problem, simply recreate the control file checking to be sure that you include all the datafiles in the system tablespace.

ORA-01174: DB_FILES is string buts needs to be string to be compatible
Cause: The maximum number of database files supported by this instance is not the same as for the other instances. All instances must be able to open all the files any instance can open.
Action: Change the value of the DB_FILES parameter to be compatible

ORA-01175: data dictionary has more than the string files allowed by the instance
Cause: The data dictionary is found to have more files than that which can be supported by this instance.
Action: Shutdown the instance and restart with a larger number of db_files

ORA-01176: data dictionary has more than the string files allowed by the controlfie
Cause: After a CREATE CONTROLFILE, the data dictionary was found to have more datafiles than that supported by the control file.
Action: Recreate the control file with a larger MAXDATAFILES.

ORA-01177: data file does not match dictionary - probably old incarnation
Cause: When comparing the control file with the data dictionary after a CREATE CONTROLFILE or OPEN RESETLOGS, it was noted that this datafile was inconsistent with the dictionary. Most likely the file is a backup of a file that was dropped from the database, and the same file number was reused for a new file. It may also be that an incomplete recovery stopped at a time when this file number was used for another datafile.
Action: Do a CREATE CONTROLFILE with the correct file or none at all.

ORA-01178: file string created before last CREATE CONTROLFILE, cannot recreate
Cause: Attempted to use ALTER DATABASE CREATE DATAFILE to recreate a datafile that existed at the last CREATE CONTROLFILE command. The information needed to recreate the file was lost with the control file that existed when the file was added to the database.
Action: Find a backup of the file, and recover it. Do incomplete recovery to time before file was originally created.

ORA-01179: file string does not exist
Cause: During datafile recovery, a file was listed which was not part for the database.
Action: Recheck the datafile name. Remember to use double quotes at the SQLDBA command line and remember that the file name is translated in the environment of the SQLDBA.

ORA-01180: can not create datafile 1
Cause: Attempting to create datafile 1 using ALTER DATABASE CREATE DATAFILE.
Action: Recover file from a backup or recreate database.

ORA-01181: file string created before last known RESETLOGS, cannot recreate
Cause: Attempted to use ALTER DATABASE CREATE DATAFILE to recreate a datafile that existed before the last known RESETLOGS.
Action: Find a backup of the file, and recover it. Do incomplete recovery to time before file was originally created.

ORA-01182: cannot create database file string - file is in use or recovery
Cause: Attempted to use ALTER DATABASE CREATE DATAFILE to recreate a datafile that is online in an open instance or is being recovered.
Action: Close database in all instances and end all recovery sessions

ORA-01183: cannot mount database in SHARED mode
Cause: Some other instance has the database mounted exclusive.
Action: Shutdown other instance then mount shared.

ORA-01184: logfile group string already exists
Cause: An ALTER DATABASE ADD LOGFILE command specified a log number for the new log which is already in use.
Action: Specify a different logfile number, or let the database choose an unused value.

ORA-01185: logfile group number string is invalid
Cause: An ALTER DATABASE ADD LOGFILE command specified a log number for the new log which is too large.
Action: Specify a correct logfile number.

ORA-01186: file string failed verification tests
Cause: The data file did not pass the checks to insure it is part of the database. See the accompanying error messages for the reason the verification failed.
Action: Make the correct file available to the database. Then, either open the database, or execute ALTER SYSTEM CHECK DATAFILES.

ORA-01187: cannot read from file string because it failed verification tests
Cause: The data file did not pass the checks to insure it is part of the database. Reads are not allowed until it is verified.
Action: Make the correct file available to the database. Then, either open the database, or execute ALTER SYSTEM CHECK DATAFILES.

ORA-01188: Block size string in header does not match physical block size string
Cause: A log file member given to CREATE CONTROLFILE is on a physical device that has a different block size than the device originally used to create the log.
Action: Move the file to a device with the correct block size or use the RESETLOGS option to CREATE CONTROLFILE.

ORA-01189: file is from a different RESETLOGS than previous files
Cause: In a CREATE CONTROLFILE command either this file or all previous files were backups from before the last RESETLOGS. This may also occur if this is a file that is offline and has been offline since before the last RESETLOGS.
Action: If the file was taken offline normal before the last RESETLOGS, and is still offline, omit it from the CREATE CONTROLFILE command. Rename and online the file after the database is open. Otherwise find the version of the mentioned file consistent with the rest of the datafiles and resubmit the command.

ORA-01190: control file or data file string is from before the last RESETLOGS
Cause: Attempting to use a data file when the log reset information in the file does not match the control file. Either the data file or the control file is a backup that was made before the most recent ALTER DATABASE OPEN RESETLOGS.
Action: Restore file from a more recent backup.

ORA-01191: file string is already offline - cannot do a normal offline
Cause: When attempting to do a normal tablespace offline it was discovered that one of the files in the tablespace was already offline.
Action: Either bring the datafile online first, or use another tablespace offline option.

ORA-01192: must have at least one enabled thread
Cause: You must specify at least two logfiles from at least one thread at the create contolfile command line.
Action: Find the missing logfiles and resubmit the command with the newly found logfiles included in the command line.

ORA-01193: file string is not the same file seen at start of recovery
Cause: A different copy of the file was accessed the last time media recovery looked at the file header. A backup of the file was restored or the meaning of the file name changed during recovery.
Action: Ensure the correct file is available, then retry recovery.

ORA-01194: file string needs more recovery to be consistent
Cause: An incomplete recovery session was started, but an insufficient number of logs were applied to make the file consistent. The reported file was not closed cleanly when it was last opened by the database. It must be recovered to a time when it was not being updated. The most likely cause of this error is forgetting to restore the file from a backup before doing incomplete recovery.
Action: Either apply more logs until the file is consistent or restore the file from an older backup and repeat recovery.

ORA-01195: online backup of file string needs more recovery to be consistent
Cause: An incomplete recovery session was started, but an insufficient number of logs were applied to make the file consistent. The reported file is an online backup which must be recovered to the time the backup ended.
Action: Either apply more logs until the file is consistent or restore the database files from an older backup and repeat recovery.

ORA-01196: file string is inconsistent due to a failed media recovery session
Cause: The file was being recovered but the recovery did not terminate normally. This left the file in an inconsistent state. No more recovery was successfully completed on this file.
Action: Either apply more logs until the file is consistent or restore the backup again and repeat recovery.

ORA-01197: thread string only contains one log
Cause: During CREATE CONTROLFILE all threads represented in the logs must be represented by at least two logs. A "last log" and a second log. The named thread does not contain two such logs.
Action: Either find more logs from the named thread. Or use the RESETLOGS option to CREATE CONTROLFILE.

ORA-01198: must specify size for log file if RESETLOGS
Cause: File sizes must be given for all logfiles if doing a CREATE CONTROLFILE with the RESETLOGS option.
Action: Resubmit the command with the appropriate logfile size.

ORA-01199: file string is not in online backup mode
Cause: Attempting to end an online backup for a file that is not in online backup.
Action: Do not enter command since it is not needed.

ORA-01200: actual file size of string is smaller than correct size of string blocks
Cause: The size of the file as returned by the operating system is smaller than the size of the file as indicated in the file header and the control file. Somehow the file has been truncated. Maybe it is the result of a half completed copy.
Action: Restore a good copy of the data file and do recovery as needed.

ORA-01201: file string header failed to write correctly
Cause: An I/O error was reported for the file header. The error was trapped and a second attempt will be made.
Action: The file probably will require recovery. Further error messages will indicate what is needed.

ORA-01202: wrong incarnation of this file - wrong creation time
Cause: The creation time in the file header is not the same as the creation time in the control file. This is probably a copy of a file that was dropped.
Action: Restore a current copy of the data file and do recovery as needed.

ORA-01203: wrong incarnation of this file - wrong creation SCN
Cause: The creation SCN in the file header is not the same as the creation SCN in the control file. This is probably a copy of a file that was dropped.
Action: Restore a current copy of the data file and do recovery as needed.

ORA-01204: file number is string rather than string - wrong file
Cause: The file number in the file header is not correct. This is probably a restored backup of the wrong file, but from the same database.
Action: Restore a copy of the correct data file and do recovery as needed.

ORA-01205: not a data file - type number in header is string
Cause: The file type in the header is not correct for a data file. This is probably a log file or control file. If the type is not a small non-zero positive number then the header is corrupted.
Action: Restore a copy of the correct data file and do recovery as needed.

ORA-01206: file is not part of this database - wrong database id
Cause: The database ID in the file header does not match the database id in the control file. The file may be from a different database, or it may not be a database file at all. If the database was rebuilt, this may be a file from before the rebuild. Note that if you see this error when the file is supposed to be plugged in from another database via the Transportable Tablespace feature, it means the database ID in the file header does not match the one expected.
Action: Restore a copy of the correct data file and do recovery as needed.

ORA-01207: file is more recent than control file - old control file
Cause: The control file change sequence number in the data file is greater than the number in the control file. This implies that the wrong control file is being used. Note that repeatedly causing this error can make it stop happening without correcting the real problem. Every attempt to open the database will advance the control file change sequence number until it is great enough.
Action: Use the current control file or do backup control file recovery to make the control file current. Be sure to follow all restrictions on doing a backup control file recovery.

ORA-01208: data file is an old version - not accessing current version
Cause: The checkpoint in the file header is less recent than in the control file. If opening a database that is already open by another instance, or if another instance just brought this file online, the file accessed by this instance is probably a different version. Otherwise, a backup of the file probably was restored while the file was in use.
Action: Make the correct file available to the database. Then, either open the database, or execute ALTER SYSTEM CHECK DATAFILES.

ORA-01209: data file is from before the last RESETLOGS
Cause: The reset log data in the file header does not match the control file. If the database is closed or the file is offline, the backup is old because it was taken before the last ALTER DATABASE OPEN RESETLOGS command. If opening a database that is open already by another instance, or if another instance just brought this file online, the file accessed by this instance is probably a different version. Otherwise, a backup of the file probably was restored while the file was in use.
Action: Make the correct file available to the database. Then, either open the database, or execute ALTER SYSTEM CHECK DATAFILES.

ORA-01210: data file header is media corrupt
Cause: The file header block is internally inconsistent. The beginning of the block has a header with a checksum and other data for insuring the consistancy of the block. It is possible that the last disk write did not operate correctly. The most likely problem is that this is not a datafile for any database.
Action: Have operating system make correct file available to database. If the trace file dump indicates that only the checksum is wrong, restore from a backup and do media recovery.

ORA-01211: Oracle7 data file is not from migration to Oracle8
Cause: The file is not a copy of the file LAST used under Oracle7. This datafile is either a backup taken from before the migration, or the database was opened by Oracle7 after the migration utility was run. When converting a database from Oracle7 to Oracle8, the migration program MUST be the LAST utility to access the database under Oracle7. Only the datafiles that were current when the migration was done may be accessed by Oracle8.
Action: Have operating system make correct data file available to database, or repeat the Oracle7 to Oracle8 migration. Make sure that database is NOT opened after migration utility is run.

ORA-01212: MAXLOGMEMBERS may not exceed string
Cause: MAXLOGMEMBERS specified on the command line too large.
Action: Resubmit the command with a smaller MAXLOGMEMBERS

ORA-01213: MAXINSTANCES may not exceed string
Cause: MAXINSTANCES specified on the command line too large.
Action: Resubmit the command with a smaller MAXINSTANCES

ORA-01214: MAXLOGHISTORY may not exceed string
Cause: MAXLOGHISTORY specified on the command line too large.
Action: Resubmit the command with a smaller MAXLOGHISTORY

ORA-01215: enabled thread string is missing after CREATE CONTROLFILE
Cause: A CREATE CONTROLFILE statement was given which did not list all the enabled threads for the database.
Action: Reissue the CREATE CONTROLFILE statement, including all enabled threads.

ORA-01216: thread string is expected to be disabled after CREATE CONTROLFILE
Cause: A thread that was given during CREATE CONTROLFILE is enabled, but the datafiles indicate that it should be disabled. This is probably because the logs supplied to the CREATE CONTROLFILE are old (from before the disabling of the thread).
Action: This thread is not required to run the database. The CREATE CONTROLFILE statement can be reissued without the problem thread, and, if desired, the thread can be recreated after the database is open.

ORA-01217: logfile member belongs to a different logfile group
Cause: A member of a multiple-member logfile group specified in a CREATE CONTROLFILE is not part of the same group as previous members.
Action: Group together the correct members for the CREATE CONTROLFILE command.

ORA-01218: logfile member is not from the same point-in-time
Cause: A member of a multiple-member logfile group is from a different point in time. One of the members specified may be an older (backup) copy of the log.
Action: Find the correct version of the log, or leave it out of the CREATE CONTROLFILE command.

ORA-01219: database not open: queries allowed on fixed tables/views only
Cause: A query was issued against an object not recognized as a fixed table or fixed view before the database has been opened.
Action: Re-phrase the query to include only fixed objects, or open the database.

ORA-01220: file based sort illegal before database is open
Cause: A query issued against a fixed table or view required a temporary segment for sorting before the database was open. Only in-memory sorts are supported before the database is open.
Action: Re-phrase the query to avoid a large sort, increase the values of the SORT_AREA_SIZE and/or SORT_AREA_RETAINED_SIZE initialization parameters to enable the sort to be done in memory.

ORA-01221: data file string is not the same file to a background process
Cause: When the database writer opens the data file, it is accessing a different physical file than the foreground doing the recovery. The timestamp set in the file header by the foreground was not found by the background. It may be that the background process could not read the file at all.
Action: Look in the DBWR trace file for the error it recieved when attempting to read the file header. Reconfigure the operating system as needed to have the file name successfully access the same file when opened by a background process.

ORA-01222: MAXINSTANCES of string requires MAXLOGFILES be at least string, not string
Cause: Attemping to create a database or control file that does not have room for at least two logs per thread of redo. A thread of redo must have two online logs in order to be enabled. It does not make sense to allow more redo threads than can be supported by the logs.
Action: Either reduce the MAXINSTANCES argument or increase MAXLOGFILES.

ORA-01223: RESETLOGS must be specified to set a new database name
Cause: The SET database name option was specified to CREATE CONTROLFILE, but RESETLOGS was not specified. The database name can only be changed when opening the database with RESETLOGS.
Action: Either add the RESETLOGS option or drop the SET option to CREATE CONTROLFILE.

ORA-01224: group number in header string does not match GROUP string
Cause: Group number specified at CREATE CONTROLFILE does not match the group number stored in the header. Most likely the specification is wrong.
Action: Omit the GROUP option or give the correct one.

ORA-01225: thread number string is greater than MAXINSTANCES string
Cause: The log is for a thread greater than the MAXINSTANCES argument.
Action: Increase the value for MAXINSTANCES and resubmit the command.

ORA-01226: file header of log member is inconsistent with other members
Cause: The log file member in the accompanying error is for the same group as the previous members, but other fields in the header are different. Either a file header is corrupted, or some file is a member of a deleted log.
Action: Find the correct log member or omit this member from the command.

ORA-01227: log string is inconsistent with other logs
Cause: The log file in the accompanying error is inconsistent with the contents of other logs given in the CREATE CONTROLFILE command. Either a file header is corrupted, or some file is an old copy rather than the current version. The problem may not be with the log listed since all that can be detected is that there is an inconsistancy. All log files listed in the command must be the current versions of the online logs.
Action: Find the correct online logs or use the RESETLOGS option.

ORA-01228: SET DATABASE option required to install seed database
Cause: The SET DATABASE option was not included in the CREATE CONTROLFILE command when installing a seed database. The database does not have a database ID because it is intended to be installed at multiple sites, and each site needs to be a different database with its own database id. Both the SET DATABASE and RESETLOGS options must be specified to create the control file for this database.
Action: Resubmit command with the SET DATABASE and RESETLOGS options.

ORA-01229: data file string is inconsistent with logs
Cause: The data file in the accompanying error is inconsistent with the contents of the logs given in the CREATE CONTROLFILE command. The most likely cause is that one or more of the online logs was missing from the command. It is also possible that one or more of the logs is an old copy rather than the current version. All online log files must be listed in the command and must be the current versions of the online logs.
Action: Find the correct online logs or use the RESETLOGS option.

ORA-01230: cannot make read only - file string is offline
Cause: An attempt to make a tablespace read only found that one of its files is offline.
Action: Bring the file online and retry this command.

ORA-01231: cannot make read write - file string is offline
Cause: An attempt to make a tablespace read write found that one of its files is offline.
Action: Bring the file online and retry this command.

ORA-01232: cannot start online backup - file string is being made read-only
Cause: An attempt to start an online backup found that one of the files is in transition to read-only mode.
Action: Wait for the transition to complete and then retry the command, if this is an ALTER DATABASE BEGIN BACKUP command, or take the backup without any begin or end commands, if this is an ALTER TABLESPACE BEGIN BACKUP command.

ORA-01233: file string is read only - cannot recover using backup control file
Cause: An attempt to do media recovery using a backup control file found that one of the files is marked read only. Read only files do not normally need to be recovered, but recovery with a backup control file must recover all online files.
Action: If the file really is read only, take it offline before the recovery, and bring the read only tablespace online after the database is open. If the file does need recovery use a control file from the time the file was read-write. If the correct control file is not available, use CREATE CONTROLFILE to make one.

ORA-01234: cannot end backup of file string - file is in use or recovery
Cause: Attempted to end an online backup of file when the file is busy. Some operation such as recovery or rename may be active, or there may still be some instance that has the database open with this file online.
Action: If there is an instance with the database open then the backup can be ended there by using the ALTER TABLESPACE command. Otherwise wait for the completion of the other operation.

ORA-01235: END BACKUP failed for string file(s) and succeeded for string
Cause: One or more of the files in an end backup command failed. Some other files given in the same command may have succeeded.
Action: See the accompanying error messages for the reason the backups could not be ended. Any files not listed in the error messages were successful.

ORA-01236: Error string occurred during initialization of file header access
Cause: The indicated error occurred while doing initialization processing of file headers.
Action: The error indicated should be corrected. An attempt is made to recover from this error by using a slower access algorithm.

ORA-01237: cannot extend datafile string
Cause: An operating system error occurred during the resize.
Action: Fix the cause of the operating system error and retry the command.

ORA-01238: cannot shrink datafile string
Cause: An operating system error occurred during the resize.
Action: The error is ignored, operation continues normally.

ORA-01239: database must be in ARCHIVELOG mode to use external cache
Cause: An online file uses an external cache, but the database is in NOARCHIVELOG mode. Since an external cache may require media recovery this can not be allowed.
Action: Change database to be in ARCHIVELOG mode or do not use an external cache.

ORA-01240: too many data files to add in one command
Cause: The command specifies adding more data files than can be done in one command. It is necessary to fit all the file names into one log entry, but that would make the entry too large.
Action: If this is a CREATE TABLESPACE command, create with fewer files then add the other files later. If this is an ADD DATAFILE command, break it up into multiple commands.

ORA-01241: an external cache has died
Cause: The external cache may have been restarted.
Action: Take the file mentioned in the error stack offline, perform media recovery, bring the file online, and retry the attempted operation. You may also restart all instances to make sure they access all data files through consistent external caches.

ORA-01242: data file suffered media failure: database in NOARCHIVELOG mode
Cause: The database is in NOARCHIVELOG mode and a database file was detected as inaccessible due to media failure.
Action: Restore accessibility to the file mentioned in the error stack and restart the instance.

ORA-01243: system tablespace file suffered media failure
Cause: A system tablespace file was detected as inaccessible due to media failure.
Action: Restore accessibility to the file mentioned in the error stack and restart the instance.

ORA-01244: unnamed datafile(s) added to control file by media recovery
Cause: Media recovery with a backup control file or a control file that was rebuilt, encountered the creation of a datafile that was not in the control file. An entry has been added to the control file for the new datafiles, but with the file name UNNAMEDnnnn, where nnnn is the file number. Attached errors describe the file names that were originally used to create the files.
Action: Rename the files to valid file names and resume recovery. If necessary the command ALTER DATABASE CREATE DATAFILE may be used to create a file suitable for recovery and do the rename. If the file is not going to be recovered then take it offline with the FOR DROP option.

ORA-01245: offline file string will be lost if RESETLOGS is done
Cause: Attempting to do an OPEN RESETLOGS with a file that will be lost because it is offline. The file was not taken offline with the FOR DROP option.
Action: Either bring the file online and recover it, or take it offline with the FOR DROP option.

ORA-01246: recovering files through TSPITR of tablespace string
Cause: The files named in the accompanying errors are backups that were made before a tablespace point in time recovery of this tablespace. They cannot be recovered to a time after the point in time recovery.
Action: Restore more recent backups and recover them.

ORA-01247: database recovery through TSPITR of tablespace string
Cause: Recovery of the whole database encountered redo indicating there was a point in time recovery of the tablespace. The new version of the files in the tablespace should be included in the recovery, but that was not done.
Action: If the tablespace should not be recovered, take its file offline for drop. If it should be recovered, then restore or rename as needed and restart the recovery.

ORA-01248: file string was created in the future of incomplete recovery
Cause: Attempting to do a RESETLOGS open with a file entry in the control file that was originally created after the UNTIL time of the incomplete recovery. Allowing such an entry may hide the version of the file that is needed at this time. The file number may be in use for a different file which would be lost if the RESETLOGS was allowed.
Action: If more recovery is desired then apply redo until the creation time of the file is reached. If the file is not wanted and the same file number is not in use at the stop time of the recovery, then the file can be taken offline with the FOR DROP option. Otherwise a different control file is needed to allow the RESETLOGS. Another backup can be restored and recovered, or a control file can be created via CREATE CONTROLFILE.

ORA-01249: archiving not allowed in a clone database
Cause: Attempting to archive an online redo log or enable archiving for a clone database.
Action: Do not attempt to archive from a clone. The archive log destination could easily be the same as the primary database destroying its archived logs. If archiving is needed then recreate database as not a clone.

ORA-01250: Error string occurred during termination of file header access
Cause: The indicated error occurred while terminating the processing of file headers. The error was other than a write error.
Action: The indicated error should be corrected.

ORA-01251: Unknown File Header Version read for file number string
Cause: Read of the file header returned a record but its version cannot be identified. Either the header has been corrupted, or the file is not a valid database file.
Action: Have the operating system make the correct file available to the database, or recover the file.

ORA-01252: cannot prevent writes - file string in recovery manager backup
Cause: An attempt to make a tablespace read only or offline normal found that a recovery manager proxy backup is in progress. If the file is made offline or read-only, then the file header cannot be updated when the backup is complete.
Action: Wait for the Recovery Manager backup to complete and retry this command.

ORA-01253: cannot start online backup - file string in recovery manager backup
Cause: The specified file is being backed up by Recovery Manager.
Action: Wait for the Recovery Manager proxy backup to complete before starting another backup.

ORA-01254: cannot end online backup - file string in recovery manager backup
Cause: The specified file is being backed up by Recovery Manager.
Action: Wait for the Recovery Manager proxy backup to complete. Recovery Manager backup mode cannot be initiated or terminated manually.

ORA-01255: cannot shutdown - file string in recovery manager backup
Cause: An attempt to shutdown normally found that a Recovery Manager backup is still in progress.
Action: Wait for the Recovery Manager proxy backup to complete and retry this command.

ORA-01256: error in locking database file string
Cause: The file is in use by another database instance.
Action: Determine which database instance legitimately owns the file.

ORA-01257: cannot reuse database file string, unknown file size
Cause: The size of the raw partion cannot be determined
Action: Add the datafile/logfile by specifying the size parameter.

ORA-01258: unable to delete temporary file string
Cause: A DROP TABLESPACE INCLUDING CONTENTS AND DATAFILES or ALTER DATABASE TEMPFILE DROP INCLUDING DATAFILES operation was not able to delete a temporary file in the database.
Action: Subsequent errors describe the operating system error that prevented the file deletion. Fix the problem, if possible, and manually purge the file.

ORA-01259: unable to delete datafile string
Cause: A DROP TABLESPACE INCLUDING CONTENTS AND DATAFILES operation was not able to delete a datafile in the tablespace.
Action: Subsequent errors describe the operating system error that prevented the file deletion. Fix the problem, if possible, and manually purge the file.

ORA-01260: warning: END BACKUP succeeded but some files found not to be in backup mode
Cause: END BACKUP completed successfully for all files that were in online backup mode. However one or more modifiable files were found not to be in online backup mode. Backup of those files (if it was done) can be invalid and, if restored, can result in an inconsistent database.
Action: Check the alert log for a list of the files that were found not to be in backup mode. If there is a possibility that those files have been modified during online backup, then replace their backups with new ones.

ORA-01261: Parameter string destination string cannot be translated
Cause: The value for the specified parameter contained a destination string that could not be translated.
Action: Use a valid destination string in the specified parameter.

ORA-01262: Stat failed on a file destination directory
Cause: Unable to get information about an Oracle managed files destination directory.
Action: Check the permissions on the directory or use a different directory name.

ORA-01263: Name given for file destination directory is invalid
Cause: The name given for an Oracle managed files destination does not correspond to a directory.
Action: Use a different name.

ORA-01264: Unable to create string file name
Cause: Unable to create an Oracle managed file name.
Action: , if possible, and retry the command.

ORA-01265: Unable to delete string string
Cause: An error prevented the file from being deleted.
Action: See the subsequent error messsages that describe the operating system error that prevented the file from being deleted. If possible, fix the problem and manually delete the file.

ORA-01266: Unable to create unique file name
Cause: Unable to create a unique file name for an Oracle managed file. Oracle tried several names but each file name was already in use in the default destination directory for the file type.
Action: Retry the operation. If that fails, also, it may be necessary to change the default destination directory for the file type and then retry.

ORA-01267: Failure getting date/time
Cause: Could not get date/time when trying to create unique file name.
Action: Internal error - contact Oracle Customer Support.

ORA-01268: invalid TEMPFILE clause for alter of permanent TABLESPACE
Cause: A TEMPFILE clause was specified for an ALTER TABLESPACE for a permanent tablespace.
Action: Retry with a DATAFILE clause.

ORA-01269: Destination parameter string is too long
Cause: The value for DB_CREATE_FILE_DEST, DB_CREATE_ONLINE_LOG_DEST_n or DB_RECOVERY_FILE_DEST parameter was too long.
Action: Replace the destination value for the specified parameter with a shorter character string.

ORA-01270: string operation is not allowed if STANDBY_PRESERVES_NAMES is true
Cause: An operation that renames or adds/drops a file was attempted at a standby database and STANDBY_PRESERVES_NAMES is true.
Action: Set STANDBY_PRESERVES_NAMES false if the operation must be performed.

ORA-01271: Unable to create new file name for file string
Cause: During standby database recovery an error occurred when trying to create a new file name for the indicated file.
Action: Use the ALTER DATABASE CREATE DATAFILE command with a new unique name and then resume the standby database recovery.

ORA-01272: REUSE only allowed when a file name is provided.
Cause: The REUSE parameter was specified in a command without a file name.
Action: Either supply a file name or remove the REUSE parameter.

ORA-01273: STANDBY_FILE_MANAGEMENT = AUTO needs COMPATIBLE = string or higher
Cause: Automated standby file management was disabled, so an added file
Action: Restart the instance with COMPATIBLE set to the correct release.

ORA-01274: cannot add datafile 'string' - file could not be created
Cause: Automated standby file management was disabled, so an added file could not automatically be created on the standby. The error from the creation attempt is displayed in another message. The control file file entry for the file is 'UNNAMEDnnnnn'.
Action: Use the ALTER DATABASE CREATE DATAFILE statement to create the file, or set STANDBY_FILE_MANAGEMENT to AUTO and restart standby recovery.

ORA-01275: Operation string is not allowed if standby file management is automatic.
Cause: An operation that renames, adds, or drops a file was attempted at a standby database and STANDBY_FILE_MANAGEMENT was set to AUTO.
Action: Set STANDBY_FILE_MANAGEMENT to MANUAL if the operation must be performed.

ORA-01276: Cannot add file string. File has an Oracle Managed Files file name.
Cause: An attempt was made to add to the database a datafile, log file, control file, snapshot control file, backup control file, datafile copy, control file copy or backuppiece with an Oracle Managed Files file name.
Action: Retry the operation with a new file name.

ORA-01277: file 'string' already exists
Cause: An ALTER DATABASE BACKUP CONTROLFILE TO TRACE AS 'filename' command specified a file name which is already in use.
Action: Either specify a different file name, or add the REUSE parameter to the command to overwrite the existing file.

ORA-01278: error creating file 'string'

ORA-01610: recovery using the BACKUP CONTROLFILE option must be done
Cause: Either an earlier database recovery session specified BACKUP CONTROLFILE, or the control file was recreated with the RESETLOGS option, or the control file being used is a backup control file. After that only BACKUP CONTROLFILE recovery is allowed and it must be followed by a log reset at the next database open.
Action: Perform recovery using the BACKUP CONTROFILE option.

ORA-01611: thread number string is invalid - must be between 1 and string
Cause: A thread number in a command is greater than the number of threads supported by the control file.
Action: Use a thread number that is valid, or resize the thread record and/or checkpoint progress record sections of the control file.

ORA-01612: instance string (thread string) is already enabled
Cause: An attempt was made to enable a thread that is already enabled.
Action: Either use this thread or enable another thread.

ORA-01613: instance string (thread string) only has string logs - at least 2 logs required to enable.
Cause: The thread cannot be enabled because it only has two online log files associated with it.
Action: Add logs to the thread or pick another thread to enable

ORA-01614: instance string (thread string) is busy - cannot enable
Cause: The mount enqueue for the thread could not be acquired when attempting to enable the thread. This probably means that another process has already started enabling this thread.
Action: Wait and try again, or find another thread to enable.

ORA-01615: instance string (thread string) is mounted - cannot disable
Cause: Some instance, possibly this one, has allocated the thread for its use. The thread can not be disabled while in use.
Action: Shut the instance down cleany using the thread.

ORA-01616: instance string (thread string) is open - cannot disable
Cause: The thread is not closed. The last instance to use the thread died leaving the thread open. A thread cannot be disabled until it is closed. It is still required for crash or instance recovery.
Action: If the database is open, instance recovery should close the thread soon - wait a few minutes. Otherwise open the database - crash recovery will close the thread.

ORA-01617: cannot mount: string is not a valid thread number
Cause: The INIT.ORA parameter "thread" is not between 1 and the number of threads allowed by the control file.
Action: Shut down the instance, change the INIT.ORA parameter and startup, or resize the thread record and/or checkpoint progress record sections of the control file.

ORA-01618: redo thread string is not enabled - cannot mount
Cause: The INIT.ORA parameter "thread" requests a thread that is not enabled. A thread must be enabled before it can be mounted.

ORA-01619: thread string is mounted by another instance
Cause: The INIT.ORA parameter "thread" requests a thread that has been mounted by another instance. Only one instance may use a thread.
Action: Shutdown the instance, change the INIT.ORA parameter and startup mounting a different thread.

ORA-01620: no public threads are available for mounting
Cause: The INIT.ORA parameter "thread" is zero, its default value. There are no threads which have been publicly enabled, and not mounted.
Action: Shutdown the instance, change the INIT.ORA parameter to a thread which is privately enabled and not mounted. If the database is open in another instance, then a thread may be publicly enabled.

ORA-01621: cannot rename member of current log if database is open
Cause: This is a rename command for a member of the current log for an open thread. If the database is open anywhere, the log may be in use, so the rename cannot be done.
Action: Wait until the log is not current, or mount the database exclusively.

ORA-01622: thread number must be specified - default not specific
Cause: The thread was not specified when adding a log, and the currently mounted thread was chosen by default at mount time. Since the current thread was not specified explicitly the user cannot know which thread the log will be added to.
Action: Explicitly specify the thread number either in the INIT.ORA parameter "thread", or in the add command.

ORA-01623: log string is current log for instance string (thread string) - cannot drop
Cause: A thread's current log cannot be dropped even if the thread is closed. A disabled thread usually does not have a current log, but a half completed disable may need to be disabled again.
Action: If the database is not open then disable the thread. If the database is open and an instance has the thread open, then the instance can be requested to switch logs. If the database is closed the log can be archived or cleared to force a switch.

ORA-01624: log string needed for crash recovery of instance string (thread string)
Cause: A log cannot be dropped or cleared until the thread's checkpoint has advanced out of the log.
Action: If the database is not open, then open it. Crash recovery will advance the checkpoint. If the database is open force a global checkpoint. If the log is corrupted so that the database cannot be opened, it may be necessary to do incomplete recovery until cancel at this log.

ORA-01625: rollback segment 'string' does not belong to this instance
Cause: Trying to shrink or take a rollback segment offline that does not belong to this instance.
Action: None

ORA-01626: rollback segment number 'string' cannot handle more transactions

Cause: The instance is trying to online an already online RS
Action: None

ORA-01637: rollback segment 'string' is being used by another instance (#string)
Cause: The instance is trying to online a RS already in use by another instance
Action: None

ORA-01638: parameter string does not allow ORACLE version string to mount cluster database
Cause: The recovery compatible parameter is set too low to allow this software version to mount in cluster database mode.
Action: Either use an earlier software release or advance the recovery_compatible parameter. If this happens when no recovery_compatible parameter has been specified then set it to the current software release.

ORA-01639: instance string has no thread assigned to it
Cause: There is no mapping from instance to thread for this instance in the control file.
Action: Make sure that this instance has a thread assigned to it by adding logfiles to this instance or by starting the instance with an existing thread which will automatically create a mapping.

ORA-01640: cannot make tablespace read only with active transactions
Cause: Attempting to make a tablespace read only while there are active transactions in the database. All transactions must commit or rollback to insure that there is no undo for a tablespace before it can be made read only. This includes in doubt distributed transactions.
Action: Prevent any more transactions from being started. Putting the database in restricted mode usually helps. If there are any in doubt transactions they must also be resolved.

ORA-01641: tablespace 'string' is not online - cannot add data file
Cause: Attempting to add a datafile to a tablespace that has been set to read only or offline.
Action: Make the tablespace online and read write then add the datafile.

Cause: Tried to allocate space in a read only tablespace
Action: Create the object in another tablespace

ORA-01648: log string is the current log of disabled instance string (thread string)
Cause: An attempt to enable the thread failed after it was half completed. This log was left as the current log even though the thread is still disabled. Since a log switch cannot be done until the thread is enabled, the log can not be cleared or archived.
Action: Complete the thread enable by issuing the enable command again.

ORA-01649: operation not allowed with a backup control file
Cause: An attempt is being made to perform a command that does not make sense when the control file is a restored backup.

ORA-01668: standby database requires DROP option for offline of data file
Cause: Attempting to take a datafile offline in a standby database without specifying the DROP option. Files that are offline in a standby database are not recovered, and are likely to be unusable if the standby is activated. Note that specifying DROP does not prevent bringing the file online later.
Action: Specify the DROP option or leave the file online.

ORA-01669: standby database control file not consistent
Cause: Attempting to activate a standby database with a control file that has not been recovered to the same point as the data files. Most likely the control file was just copied from the primary database and has not been used for recovery.
Action: Recover the standby database until all the files are consistent.

ORA-01670: new datafile string needed for standby database recovery
Cause: Standby database recovery noticed that a file was added to the primary database, but is not available on the standby.
Action: Either copy the file from the primary database or do an ALTER DATABASE CREATE DATAFILE command on the standby to create a file to recover.

ORA-01671: control file is a backup, cannot make a standby control file
Cause: The currently mounted control file is a backup control file, and attempting to create a control file for a standby database.
Action: Complete any needed recovery and open the database with the resetlogs option.

ORA-01672: control file may be missing files or have extra ones
Cause: Attempting to create a standby control file, but the control file was either recently created via CREATE CONTROLFILE or an incomplete recovery has been done. Thus the datafiles in the control file and the ones in the data dictionary may not match.
Action: Open the database, then retry the operation.

ORA-01673: data file string has not been identified
Cause: This data file was not in the control file after an incomplete recovery or CREATE CONTROLFILE. Since information from its header is needed for standby database recovery, we can not create a standby control file.
Action: Find the file and bring it online. If desired it may be taken offline again. If you intend to drop this file, then taking it offline with the DROP option will avoid this error.

ORA-01674: data file string is an old incarnation rather than current file
Cause: Recovery encountered redo that indicates this file was dropped from the database and another file was added using the same file number. This implies that a CREATE CONTROLFILE command was given the old file which was dropped rather than the latest file.
Action: Rebuild the control file using CREATE CONTROLFILE, and give the correct file.

ORA-01675: max_commit_propagation_delay inconsistent with other instances
Cause: The max_commit_propagation_delay INIT.ORA parameter is inconsistent with those in other instances.
Action: Make sure all instances have the same max_commit_propagation_delay.

ORA-01676: standby file name convert of 'string' exceeds maximum length of string
Cause: When the given file name is converted to the name used for the standby database, the converted name is bigger than the maximum allowed file name.
Action: Change initialization parameter DB_FILE_STANDBY_NAME_CONVERT or LOG_FILE_STANDBY_NAME_CONVERT to convert to a valid file name.

ORA-01677: standby file name convert parameters differ from other instance
Cause: The DB_FILE_STANDBY_NAME_CONVERT or LOG_FILE_STANDBY_NAME_CONVERT initialization parameters are not the same as in other instances that already have the database mounted.
Action: Change initialization parameters DB_FILE_STANDBY_NAME_CONVERT and LOG_FILE_STANDBY_NAME_CONVERT to match other instances.

ORA-01678: parameter string must be pairs of pattern and replacement strings
Cause: The initialization parameter does not have even number of strings for its value. The odd numbered strings are patterns to be found in file names. The even numbered strings are used to replace the corresponding patterns when found in file names.
Action: Specify even number of strings for the parameter, or omit the parameter.

ORA-01679: database must be mounted EXCLUSIVE and not open to activate
Cause: An attempt to activate a standby database was made when the database was not mounted EXCLUSIVE or was already open.
Action: Mount the database EXCLUSIVE and retry the ACTIVATE command.
