Locate the SET JAVA_OPTIONS parameter.
Change or add the –XmxZZm parameter, where ZZ equals the amount of RAM, in MB, to allocate.
The following example shows the parameter set to a maximum of 128 MB.
SET JAVA_OPTIONS=-hotspot -ms1m -mx128m

5) How do you troubleshoot Application messages staying in Working status?
Possible cause:
1. Message Handler has crashed.
2. The Message Handler processing the message is on another machine, and either the machine or the application server domain is down. The Message handler working on the message is “blocked”. The service will timeout, and the Message Dispatcher will retry the message.
