Committing changes using the MQCMIT call

 

As input, supply the connection handle (Hconn) that is returned by the MQCONN or MQCONNX call.

The output from MQCMIT is a completion code and a reason code. The call completes with a warning if the syncpoint was completed but the queue manager backed out the put and get operations since the previous syncpoint.

Successful completion of the MQCMIT call indicates to the queue manager that the application has reached a syncpoint and that all put and get operations made since the previous syncpoint have been made permanent.

Not all failure responses mean that the MQCMIT did not complete. For example, the application can receive MQRC_CONNECTION_BROKEN.

There is a description of the MQCMIT call in the Application Programming Reference.
