We are getting a lot of heapdump and javacore file from our Websphere 5.1 running on Windows XP. I am getting the files sent to me. I was going to use the Heap Analyzer from IBM and perhaps the H.A.T.(Heap Analyzer Tool from Sun). Any other suggestions of tools to use or ideas to troubleshoot?
You should probally first look at why it is dumping an generating javacore files. Watch the entries of the GC to see the memory behavior od the environment, e.g. memory leak, heap size too small or not enough native memory. Starting with analyzing the heapdump is most of the times not useful.
