installation of Weblogic and always get the Sun JVM in Development mode. If you
have installed Weblogic in Development mode but want to run it in the
Production mode, Start the weblogic as follows:
$./startWebLogic.sh
-Dweblogic.ProductionModeEnabled=true
The
key-value pair "weblogic.ProductionModeEnabled=true" will start the
weblogic server in Production mode. The key difference between Development mode
and Production mode (by default, without any JDK installations specified in the
installation) is that the Development mode runs with Sun JVM and Production
mode runs with JRockit JVM.
JRockit is
enhanced JVM and enhanced for its performance. Its one of the best and fastest
JVM until now (as claimed by Oracle). If you install JRockit Mission
Control, then you can measure the performance of your Weblogic server (JRockit
also supports Sun JVM and other JVMs).
