WASX7209I: Connected to process “WebSphere_Portal” on node wcl using SOAP connector; the type of process is: unManagedProcess; WASX7029I: For help, enter: “$Help help”
wsadmin> set jvm [$AdminControl completeObjectName type=JVM,process=WebSphere_Portal,*]

IBM’s support assistant (ISA) is an Eclipse based tool with quite a number of plugins to analyze heapdumps – a good developerworks article can be found here (part I) and here (part II).
