WebSphere MQ uses the SYSPLEX Coupling Facility to facilitate shared message queues. Multiple queue managers running on different systems in the SYSPLEX can process the messages arriving in the Coupling Facility structures. Applications using shared message queues benefit from load balancing across the SYSPLEX. This query can be used to monitor structure use—a key metric shown is the Structure Full Count. If this metric is ever greater than 0, the size of the structure may need to be increased.
This query is useful to identify the most used queues by applications.
