I have tried to use the heap dump analyzer off the ISA before, but had trouble with it never giving me anything useful (probably me not knowing how to use it correctly). I found I had a lot of the same objects, but could never get it to show me the name of the object. If there were things to look for from the WAS perspective under java, that might also help.

My plan for 2008 is to see if I can get the idea of "official"courses and/or presentations on how to debug z/OS Java abends (tools, techniques), Out-of-Memory (Java and native), how to read verbosegc etc. Obviously you may well get to the point where you need access to the code, which is where we come in, so that is as far as you go. If you had a wish list (it is almost Christmas after all), what would you like to see? Websphere have a really cool Technical Exchange Webcast site: http://www-306.ibm.com/software/websphere/support/supp_tech.html Very interesting presentations! Maybe I need to talk to the owner. There are already presentations and even Redbooks out there that cover a fair percentage of this subject , but to my mind there is no real structure to locate them. How do you guys look for Java stuff (outside the ever-present Google of course), how could IBM anchor this kind of information? ------------------------------------------------------------------------ ------------------------------------------ Mike Poil Java z/OS Level 3 Service IBM United Kingdom Limited, Hursley Park, Winchester SO21 2JN Internal: 246824 External: +44 (0)1962 816824 Java debugging: http://www.ibm.com/developerworks/java/jdk/diagnosis/ ------------------------------------------------------------------------ ------------------------------------------ Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
