Generating An IBM Heap Dump On Windows

I recently was trying to force a Java heap dump on windows running in IBM WebSphere Application Server. I clicked around, found a few sites, pieced it together and got it working. Here is what I did.

• In the windows task manager, add the PID into the view so you know what to kill
• Finding the server process is as easy as the java process consuming the most memory and CPU
• Add the following VM argument
• -XX:+HeapDumpOnCtrlBreak
• Add environment variables
• IBM_HEAP_DUMP=true
• IBM_HEAPDUMP=true
• IBM_HEAPDUMPDIR=C:\WCToolkitEE60\wasprofile\logs\server1
• This can be whatever you want really, this is where I see heap dumps put in general. 
• IBM_JAVA_HEAPDUMP_TEXT=false 
• I found that the heap analyzer reads the binary files quicker
• Download
• http://www.latenighthacking.com/projects/2003/sendSignal/
• Sends the "control+break" to the process on Windows
• A link
• http://jprobe.inside.quest.com/entry.jspa?externalID=1461&categoryID=127
• I stole a lot, or learned a lot from this reference link
• Then I just started the server and used the SendSignal
• All worked to get the dump

 Since its an IBM heap, you need the IBM heap analyzer to read the dump.
