Any tools to analyze JVM Memory.

Posted: Jan 30, 2003 5:25 PM

Hi All,
In production box we have 12 JVM running inside the application server with Java options -Xms512m.
I got OurOfMemory exception from one of the JVM. I see the JVM process running in unix has HEAP size of 416M and total memory usage of 480m which throwed the exception. But other 11 JVM's have Heap of 80-90M and total memory usage of 140-160m.
Is there any tool which can connect to this live unix process in Sun Solaris 8 and give the details of the object which are loaded in the JVM so that I can isolate the problem.

Thanks in Advance.
JP
