Determining when messages are successfully requeued

Messages that are successfully requeued by the Queue Control Facility/Message Requeuer are logged to the OLDS with an identical 01 (input) or 03 (output) log record as the original, except when MSGCFLG3=MSGC3MRQ (that is, message+19=45) is set to indicate that this message was requeued by the Queue Control Facility/Message Requeuer.

This flag is propagated to other messages that originate from this message. (That is, if the message is an input transaction message the flag is propagated to the output response messages when the transaction message is processed. Or, if the message is an MSC message, it is propagated to messages in other IMS/MSC systems when the message is sent across the MSC link.)

The following figure shows an input transaction to TRANCODE=TRAN31V0 from LTERM=IMSUS02 that was requeued by QCF.
