Monitoring and requeuing structures using the Queue Control Facility
You can copy and remove messages, and query shared queues for message counts and ages, using Queue Control Facility (QCF) two ways: by submitting a QCF BMP job to run on an IMS in the shared-queues group, or by using the QCF TCO/ISPF interface.
Removing messages can be useful for clean-up or for re-inserting and processing messages later. You can also select and re-queue lost messages to the shared queues for reprocessing.
Requeuing the cold queue using QCF
When an IMS is abended and then cold started, CQS places messages in progress at the abend on the cold queues of the CQS shared-queues structure. You can analyze or delete these messages on the cold queue structure using QCF. Additionally, with QCF, you can move the messages back to one of the processing queues for re-processing.
