nothing.

Hey Amgad,

Umm... the way sendsignal works ( believe) is it sends a 'signal' to the
JVM. The JVM then decides what to do.
I know in the IBM JVM that we have properties to determine if we pass the
signal to the OS (to get a OS dump) or if we handle it and dump our own
threads

I am not an expert in Oracle/Bea or their JVM (is it Jrockit) but they may
also have parameters.. ?
For instance, I found this
(http://edocs.bea.com/wls/docs81/cluster/trouble.html) and I am wondering if
this is what you are looking for ?
I presume you are using the BEA/Oracle application server right ?

Hi Christophe,

          I'm using sendsignal.exe and am passing the PID of the OC4J
instance under which am developing my application then I check the log and I
can't find any dump just the oc4j is forced to shut down and restarted
successfully.

Hey Amgad,
I usually create a dummy exception and printStackTrace so it lists my thread
You want a 'full jvm dump' ? If so, I usually sendSignal.exe to the PID or I
use the IBM JVM and I programmaticlaly call the dump method

Does it help ?

Hi,

         Does anybody know how to get a thread dump for the JVM. I'm
developing my application under oracle application server and java 1.4 and I
need a thread dump to trace logging problem.
