The MQ subtask is released at the end of request processing in subsystems with AUTOCOMMIT=N.


You can set the MQSUBREL parameter on User 0’s CCAIN line to affect all users. Or, a user can reset it to affect only a specific user. At login or a user restart the MQSUBREL parameter is returned to the value specified by the User 0 CCAIN parameter line.

0 Retain the subtask and preserve pre-V7R1.0 behavior.
1 Release the subtask to other users.

Set this parameter to 0 when you expect the same user to use MQ services soon after ending a request. Set it to 1 when you expect other users may be waiting for a free MQ subtask.
