Queue sharing groups

Queue managers that can access the same set of shared queues form a group called a queue sharing group (QSG), and they communicate with each other using a coupling facility (CF) that stores the shared queues.

A shared queue is a type of local queue with messages that can be accessed by one or more queue managers that are in a queue sharing group. This is not the same as a queue being shared by more than one application, using the same queue manager.

Queue sharing groups have a name of up to four characters. The name must be unique in your network, and must be different from any queue manager names.

Queue sharing groups are not strictly objects, but are mentioned here for convenience.

Important: Shared queues and queue sharing groups are supported only on IBM® MQ for z/OS®.
