How to analyze core dumps in java.

[sunnyday singh]

How to get the root cause of Hung thread from java core dump?
I have attached the sample core dump file. Please help me resolving the root cause of it and help me understand how to debug such issue quickly.
Any help regarding this is highly appreciated.





Thanks n regards,

Sunny kumar.

Welcome to CodeRanch!

I'm unable to see the attachment.

Moreover, I didn't understand the question.

Do you mean to say core dump thrown by JVM? In this case, you can check it via any standard debugger like gdb. The problem is, JVM libs mostly do not contain debug information, and it is very difficult to debug it. Apart from this, it is pretty rare scenario.

If you mean thread dump or heap dump, then yes, it can be analyzed (though, 'debugging' is not proper term here).

A standard way of obtaining thread dump is to send SIGQUIT signal to JVM - it should print thread dump on standard console (may be actual console, or a file).

Heap dump of running Java process can be obtained via jmap utility - further, the heap dump can be analyzed via jhat utility.

Please TellTheDetails - which exact dump you need to obtain.

Not a “beginning” question: moving discussion.

You can't attach such files here. Text editors are not the best way to look at such files. Websphere possibly comes with its own tools, but otherwise try VisualVM, which comes with the JDK. It can visualize thread dumps in a more useful way.

I think I'm missing something here?

Is this some different kind of dump? Maybe created via some WAS tool?

The thread dumps I'm familiar with - those are simple readable text - and those only give the status (and call stack) of all live threads in JVM (e.g. running, waiting, runnable, timed_wait etc.)

[sunnyday singh]

Its ok i got the tool to analyse the same.I got this tool IBM thread and Monitor analyzer for java and yes its WAS logs.I think i only have to work this out.
Thanks for reply and suggestion.I work in a bank so i think i must not be sharing java dump files.
Thanks anyways.

I think I'm missing something here?

Is this some different kind of dump? Maybe created via some WAS tool?

The thread dumps I'm familiar with - those are simple readable text - and those only give the status (and call stack) of all live threads in JVM (e.g. running, waiting, runnable, timed_wait etc.)

You're probably not missing anything. Thread dumps are indeed text files, but no text editor I'm familiar with has facilities to analyze them; other tools (like VisualVM) do.
