2487 (09B7) (RC2487): MQRC_CALLBACK_LINK_ERROR

Explanation

On an MQCTL call, the callback handling module (CSQBMCSM or CSQBMCSX for batch and DFHMQMCM for CICS®) could not be loaded, so the adapter could not link to it.

This reason code occurs only on z/OS®.

Completion code

MQCC_FAILED

Programmer response

Ensure that the correct library concatenation has been specified in the application program execution JCL, and in the queue manager startup JCL. Any uncommitted changes in a unit of work should be backed out. A unit of work that is coordinated by the queue manager is backed out automatically.
