UDS 5.1.3 application hang : how to force a process backtrace

I need to take a thread dump on a Forte_Executor partition.

I have SunONE UDS Version 5.1.3, on SunOS 5.9.

I read on the Forte Technote ID 10398 (it's a old one : 05/14/1998) that :

"On UNIX, you can send a process a signal to get it to print a backtrace.

This is good to diagnose a hang or a spin. This is done with SIGUSR2 in the following manner:

kill -USR2 process_id".

I tried it on a UDS 5.1.3 Forte_Executor process, but the process crashes.

Does anyone know what's the signal I have to send to the process to produce a backtrace ?

I wouldn't like to use escript/econsole (showpart, dumpstatus) or solaris pstack command.

Thanks in advance

Best regards

Rob
