/DIAGNOSE commands

Use the /DIAGNOSE SNAP command to retrieve diagnostic information for system resources such as IMS™ control blocks, user-defined nodes, or user-defined transactions at any time without creating a console dump. Use the /DIAGNOSE SET command to enable or disable diagnostic features such as the logging facility that captures events related to APPC and OTMA synchronous transactions in a shared-queues environment.

The SET and SNAP keywords are mutually exclusive.
