2350 (092E) (RC2350): MQRC_CONN_TAG_NOT_USABLE
Explanation
An MQCONNX call was issued specifying one of the MQCNO_*_CONN_TAG_* options, but the call failed because the connection tag specified by ConnTag in MQCNO is being used by the queue manager for recovery processing, and this processing is delayed pending recovery of the coupling facility.
This reason code occurs only on z/OSĀ®.
Completion code
MQCC_FAILED
Programmer response
The problem is likely to persist. Consult the system programmer to ascertain the cause of the problem.
