Re: JAVA USED 95% OF THE GC HEAP.

Forgot to change the jobnumber and ran it and I got:
JVAB612-Job contains a JVM which is not supported by this command.

Ok, my bad.

So I changed the job number and reran it. I still get that message.
Recovery . . . : Use the GENJVMDMP, PRTJVMJOB, and WRKJVMJOB commands
instead of this command.

Joblog says
Server starting with user profile QEJBSVR and JDK 1.6.0.

Picked the first off of the list, GENJVMDMP. Ran "successfully". However,
where is the output? The help on the command doesn't clue me in.
Something also tells me I should have changed the default from TYPE(*JAVA)
to TYPE(*HEAP) but if I can't find the output first, who cares?

So I ran PRTJVMJOB JOB(864283/QEJBSVR/AS70SVR) OPTION(*ALL)
That generates 631 pages of stuff. Around page 8:

Then it goes on to another GC Cycle Number...
