How to find native memory usage for a domain

Hi All,

We want to know how to find out current native momory utilization for a perticular weblogic domain. Basically we want to increase our current JVM heap size from 2 GB to 3.5GB because of 32 bit JDK restriction we are not having confident to increase at the memont. If we can get the current native memory utization then we will have a idea how to pregess and change in production env.

OS - Solaris 10
Weblogic - 9.2
Java - 1.5

Thanks and Regards
Dinabandhu

    You will have to define that term, because it doesn't have any meaning to me. You could find out the memory utilization for a specific JVM, if that's what you mean, but is it?

    Surprisingly enough to me that will not work. The maximum on solaris is 2G presuming you are running on a 32 OS.

    Memory is per process. Weblogic, the server, is one process (one VM.) Thus you can't increase the application memory for only part of it. I doubt weblogic has a way to limit it by app.
