MQ Rollback

This WebSphere MQ tool executes the MQBACK call to tell queue manager that all of the message gets and puts that have occurred since the last syncpoint are to be backed out. Messages put as part of a unit of work are deleted; messages retrieved as part of a unit of work are reinstated on the queue. See the MQPUT call documentation in your WebSphere MQ Application Programming Guide for more information.

Inputs

Hconn

The connection handle to the Queue Manager. The MQConnect tool generates this connection handle. This value corresponds to the Hconn input parameter in the MQPUT call.

Outputs

Reason Code

For each call, a completion code and a reason code are returned by the queue manager or by an exit routine, to indicate the success or failure of the call. This value corresponds to the Reason code parameter in the MQBACK call. The WebSphere MQ Application Programming Guide contains a list of reason codes and their meanings.

Exit Paths

Success

This step takes the Success exit path if the completion code indicates success.

Failure

This step takes the Failure exit path if the completion code indicates failure. The reason for tool failure is contained in the Reason Code parameter.
