How do you analyze Heap Dump? How to create it in WebSphere?

A. Through Heap Analyzer Tool you can analyze Heap Dump and the extension of
Heap Dump will be .phd ( portable heap dump)
• From here you can suspect the memory leaks of the packages and class files.
• First you need to create a variable called IBM_HEAPDUMP = TRUE….
• In App servers -> server -> Java Process Mgmt -> Process Definition ->
Custom Properties---Click New -> then Give the value as :
