java heap dump

Mohd Azahari — Thu, 11 Feb 2010 04:20:00 GMT

Hi,

I have IBM websphere running on my 11.23 itanium. What I found out the websphere java process (from glance) memory usage is 2.3Gb. Could someone tell me how to get the java head dump for this process.

from kill -3

You can get the dump of this process but this would kill the process as well.

You will get Java heap core dump if memory stack size(maxtsiz/maxtsiz_64bit)or swap size is smaller than what it takes.

There is a facility of taking live dump in HPUXv3.

But if every thing is fine you need to kill the process with signal 3.

ie kill -3
