Tip: Before modifying the JVM arguments, consider
making a backup of the file. If you enter arguments that are not valid, and
then update the master configuration, you might have problems starting the
server again. If you cannot start the server, you cannot modify the JVM arguments
using the WebSphere Application
Server administrative console. The settings are stored in a file similar to:
/u/WebSphere/V6R1/AppServer/profiles/default/config/cells/TST1
/nodes/TST1/servers/server1/servant.jvm.options
TST1 should
be substituted with your mainframe node. If you cannot restart the server
after applying the JVM arguments, use the backup file to recover.
Use
the WebSphere Application
Server administrative console to set these properties.
