MDBOC (10-digit signed integer)

Backout counter.

This is a count of the number of times the message has been previously returned by the MQGET call as part of a unit of work, and subsequently backed out. It is provided as an aid to the application in detecting processing errors that are based on message content. The count excludes MQGET calls that specified any of the GMBRW* options.

The accuracy of this count is affected by the HardenGetBackout queue attribute; see Attributes for queues.

This is an output field for the MQGET call. It is ignored for the MQPUT and MQPUT1 calls. The initial value of this field is 0.
