在WebLogic中如何設定使用JRockit JVM

How to tell Our WebLogic to use JRockit JVM ?

Step-1). Set the JAVA_HOME environmental variable in
< MIDDLEWARE_HOME>/common/bin/commEnv.cmd (commEnv.sh) to the appropriate path.
Example Location: C:\Bea1033\wlserver\common\bin

Step-2). Set the JAVA_VENDOR environmental variable in
< MIDDLEWARE_HOME>/common/bin/commEnv.cmd (commEnv.sh) to BEA.

NOTE: Above two Steps are required only when you want that All your Newly created Domains as well should automatically pick the JRockit JVM Only.
If you already have some Existing Domain then you can do this in your ”\bin\setDomainEnv.sh” set the Correct JAVA_HOME and Correct JAVA_VENDOR Like below:
