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.

For more information, see Managing the coupling facility in the IBM MQ online product documentation.
