2103 (0837) (RC2103): MQRC_ANOTHER_Q_MGR_CONNECTED


Explanation

An MQCONN or MQCONNX call was issued, but the thread or process is already connected to a different queue manager. The thread or process can connect to only one queue manager at a time.

  • On z/OS, this reason code does not occur.
  • On Windows, MTS objects do not receive this reason code, as connections to other queue managers are allowed.


Completion code

MQCC_FAILED


Programmer response

Use the MQDISC call to disconnect from the queue manager that is already connected, and then issue the MQCONN or MQCONNX call to connect to the new queue manager.

Disconnect from the existing queue manager closes any queues that are currently open; it is suggested that any uncommitted units of work are committed or backed out before the MQDISC call is issued.
