2160 (0870) (RC2160): MQRC_CONN_ID_IN_USE

Explanation

On an MQCONN call, the connection identifier assigned by the queue manager to the connection between a CICS or IMS allied address space and the queue manager conflicts with the connection identifier of another connected CICS or IMS system. The connection identifier assigned is as follows:

For CICS, the applid
For IMS, the IMSID parameter on the IMSCTRL (sysgen) macro, or the IMSID parameter on the execution parameter (EXEC card in IMS control region JCL)
For batch, the job name
For TSO, the user ID

A conflict arises only if there are two CICS systems, two IMS systems, or one each of CICS and IMS, having the same connection identifiers. Batch and TSO connections need not have unique identifiers.

This reason code occurs only on z/OS .

Completion code

MQCC_FAILED

Programmer response

Ensure that the naming conventions used in different systems that might connect to the queue manager do not conflict.
