Usage notes

 

1. If there is more than one queue with a name that satisfies the generic q-name, all those queues are reset.

2. Issue this command from an application, and not the z/OS console or its equivalent, to ensure that the statistical information is recorded.

3. Each queue manager in a queue-sharing group maintains its copy of the following performance statistics independently:

   MSGIN

   Incremented each time a message is put to the shared queue

   MSGOUT

   Incremented each time a message is removed from the shared queue

   HIQDEPTH

   Calculated by comparing its current value for HIQDEPTH with the new queue depth it obtains from the coupling facility during every put operation.

   To obtain full statistics for a shared queue, you should specify CMDSCOPE(*) on RESET QSTATS to broadcast the command to all queue managers in the queue-sharing group.

   The peak queue depth approximates to the maximum of all the returned HIQDEPTH values, and the total MQPUT and MQGET counts approximates to the sum of all the returned MSGIN and MSGOUT values respectively.

4. If the PERFMEV attribute of the queue manager is DISABLED, the command fails.
