Diagnostics for use with synchronous APPC and OTMA with shared queues

Synchronous APPC and OTMA message processing in the shared queues environment introduces additional diagnostic considerations for the message flow.

In addition to the APPC and OTMA traces already used, other facilities include:

• IMS Resource Recovery Trace
• z/OS® Resource Recovery Trace
• z/OS APPC Trace
• Console memory dumps of the z/OS Resource Recovery Services and APPC address and data spaces.

If IMS is using z/OS cross-system coupling facility for communication, a memory dump of the RRS address space is unavailable.
