Manually generating heap dump

You can use the WSAdmin script to generate heapdump for the JVM. Use this Jython script to do that

def generateHeapDump(serverName):
serverJVM = AdminControl.queryNames("type=JVM,process="+serverName+",*")
print serverJVM
AdminControl.invoke(serverJVM,"generateHeapDump")


generateHeapDump("server1")


Just call the generateHeapDump() function with name of the server that you want to generate heap dump for.

Once this script is executed open the native_stderr.log file to find out the location of heap dump file. In my case i see these lines in the native_stderr.log file

JVMDUMP007I JVM Requesting Heap Dump using 'C:\Cert\WebSphere\AppServer\profiles\AppSrv01\heapdump.20090705.140924.8660.0001.phd'
JVMDUMP010I Heap Dump written to C:\Cert\WebSphere\AppServer\profiles\AppSrv01\heapdump.20090705.140924.8660.0001.phd


You can open the file name ending with .phd in the HeapAnalyzer tool
