For more information on JVM, see Tuning Java Virtual Machine.
Click Config Profiles from the Lifecycle Manager navigation menu.
Click the edit icon for the configuration profile you want to edit, or click Add config profile if you have not already added a config profile.
In the Config Profile pane under the Lifecycle Manager section, click jvm-server.options.

Adjust the default settings as appropriate for your environment.
