Re: Similar processes use different memory heap space in PA_RISC and Integrity Servers
It could be that java works differently on Integrity to get more performance. And for garbage collection.
How much different are the values?
Do you have maxdsiz the same on the two machines?

Re: Similar processes use different memory heap space in PA_RISC and Integrity Servers
Please find below the details of the memory used by both the processes.
PA_RISC2.0 :-
Total RSS/VSS - 131.3mb/1.14gb
Mem - 83%
Swap - 42%
Test - 48kb/64kb
Data - 7.9mb/7.9mb
IA64N :-
Total RSS/VSS - 588.1mb/1.23gb
Mem - 32%
Swap - 14%
Text - 148kb/164kb
Data - 7.8mb/7.8mb
I could'nt know how to check the maxdsiz.And also i have already found out that jdk1.5 uses more memory basically the garbage collector as you mentioned.I wanted to know does the PA_RISC and integrity servers have any impact too on the processes and if yes, what is the possible reason for it.

Re: Similar processes use different memory heap space in PA_RISC and Integrity Servers
The differences are totally normal... Are you running, for instance, the same Java application on both servers?
I've even seen the same application using different amounts of memory on the same server, just by using a different compiler.
In your case, you didn't only use a different compiler, but also a different piece of hardware.

I'm not sure IBM has something to do with HP-UX.
Unix operates with beer.

Re: Similar processes use different memory heap space in PA_RISC and Integrity Servers
You should download the gdb/wdb tool for debugging the application core file. See this thread:
http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1373999
and look at the attached doc on how to analyse a core dump with gdb.
