The /CQQUERY command displays information regarding a specific coupling facility list structure or all the coupling facility list structures holding IMS messages. The /CQQUERY STATISTICS command displays the statistics and status information for the coupling facility list structures specified by the STRUCTURE keyword. The following statistics information is displayed:
This command is valid only in a shared-queues environment.
In an IMSplex, /CQQUERY displays information regarding a specific shared queue coupling facility list structure or all the shared queue coupling facility list structures holding IMS messages. /CQQUERY does not display any information about resource structures.
When the /CQQ command is issued through OM, command processing is not serialized through the IMS CTL TCB.
Only primary, coupling facility list-structure names used by IMS for shared queues are valid.

Explanation: This command displays the structure statistics of the message queue and Fast Path EMH queue structures used by IMS. The list entries allocated (LEALLOC), the list entries in use (LEINUSE), the elements allocated (ELMALLOC) and the elements in use (ELMINUSE) show the usage of the structures. When CQS allocates a structure, it allocates a certain number of list entries and elements to manage data on the structure. A structure is full if all list entries are in use or if all elements are in use.

Explanation: This command displays the structure statistics of the message queue structure used by IMS and its associated overflow queue.
