Coupling facility structures
The coupling facility objects in IBM MQ Explorer represent coupling facility structures on a physical coupling facility. Coupling facility structures store the messages that are on shared queues. Each coupling facility structure used by IBM MQ is dedicated to a specific queue sharing group, but a coupling facility can hold structures for more than one queue sharing group.
The physical coupling facility exists independently of the queue sharing group network, and typically runs on a different power supply. This means that the coupling facility is resilient to software failures and can be configured to be resilient to hardware failures and power-outages. The messages on the coupling facility structures are, therefore, highly available.
