Records containing zero CPU time
Records are sometimes produced that contain zero CPU time in the QMACCPUT field. These records occur when long running tasks identified to WebSphere MQ either terminate or are prompted to output accounting records by accounting trace being stopped. Such tasks exist in the CICS adapter and in the channel initiator (for distributed queuing). The number of these tasks with zero CPU time depends upon how much activity there has been in the system:
- For the CICS adapter, this can result in up to nine records with zero CPU time.
- For the channel initiator, the number of records with zero CPU time can be up to the sum of
Adapters + Dispatchers + 6, as defined in the queue manager attributes.
These records reflect the amount of work done under the task, and can be ignored.
