Concerns and issues relating to all versions of WebSphere Application Server

Friday, July 8, 2011

 

On an intel linux platform, what are the default java parameters that are used when starting WebSphere Application Server ? java -Xmx… etc ?

You will find below ALL the user arguments used with the WAS 8 JVM. 

This was taken for a javacore triggered on WAS8 on a Windows 2003 Server 64 bit WAS install.

2CIUSERARG               -Xms50m

2CIUSERARG               -Xmx256m

How to take a javacore

wsadmin>set objectName [$AdminControl queryNames WebSphere:type=JVM,process=server1,*]

wsadmin>$AdminControl invoke $objectName dumpThreads

Look for Javacore filename:   C:\WebSphere8\m1116.12\profiles\AppSrv01\javacore.20110708.115112.4824.0001.txt
