2131 (0853) (RC2131): MQRC_ADAPTER_DEFS_ERROR
Explanation
On an MQCONN call, the subsystem definition module (CSQBDEFV for batch and CSQQDEFV for IMS) does not contain the required control block identifier.
This reason code occurs only on z/OS®.
Completion Code
MQCC_FAILED
Programmer response
Check your library concatenation. If this is correct, check that the CSQBDEFV or CSQQDEFV module contains the required subsystem ID.
