When you click the Oracle Application Server Name link on the Managed Homes page, the Management Console displays another page called Oracle Application Server Name.
To configure Oracle Application Server:
In the J2EE Containers section, complete this field for the instance you want to configure:
JVM Processes
Enter a numeric value specifying the number of JVM processes to simultaneously run within this container.
Click the Save button.
Tip:
Only the Oracle Application Server needs to be running in order for the Management Console to set this value. The OC4J instance does not need to be running.
