Edit the JAVA_OPTS section in the JBOSS_HOME/bin/run.conf file.

Thanks. Generally how much should the minimum and maximum size of the heap be? Also the MaxPermSize?

I run Jboss 24x7 365 days.

That depends entirely on your application. You will need to do load testing and monitor the garbage collection statistics under load. From there you can determine how much heap you need.

For suggestions on how to gather GC data and analyze it, see these white papers:
