You can
also use Enterprise Manager (EM) to create a duplicate (clone) database. You
can choose from the following venues for the clone operation:
•
Running
instance: You can
specify a running instance to be cloned.
•
Staging
area: A disk area
specified on the source and destination hosts. A backup is created and stored
here, then put in the destination staging area, and read from on that
destination host to create the clone database.
•
Existing
backup: If you
already have a backup that reflects the database in the state you want it
cloned, you can use that.
