How to increase JVM memory in HP UX
Hi,
Im using HP UX and tried to increase the JVM memory from 1GB to 2GB for the weblogic domain. but it did not work and started throwing errors. I would like to know if there is any OS level parameter that need to be checked and modified before making changes to JVM memory.

What version of OS?

Get hpjconfig:
https://h20392.www2.hp.com/portal/sw...mber=HPJCONFIG

My first impression is, that some of the kernel parameters might be set too
low (max_thread_proc). So please execute hpjconfig, and set the kernel
parameters according to the suggestions of the program.

You could compare...

But the best would be my above recommendation ( get and use hpjconfig...)
