Pulling a stack dump from a live resource manager

You can create a stack dump from a live resource manager on Linux® on System x or System z®, and AIX® 5.3 or higher. To obtain a stack dump of a currently running IBM.RecoveryRM or IBM.GblResRM, proceed as follows:

1. Get the PID. Enter

   ps –ef | grep RMd

   or

   lssrc –l –s <resource manager>

2. Send the SIGUSR1 signal to the resource manager process, enter

   kill –SIGUSR1 <pid>

3. The resource manager creates a stack dump file for each thread named stackdump_<resource manager>_tid_-<thread ID>.xml and locates the file in its default run directory /var/ct/<domain>/run/mc/<resource manager>. The stack dump files are XML files containing information about the execution state of the resource manager. This file is used by for IBM® support.
