Indirect queues

Intrapartition and extrapartition queues can be used as indirect queues. Indirect queues provide some flexibility in program maintenance in that data can be routed to one of several queues with only the transient data definition, and not the program itself, having to be changed.

When a transient data definition has been changed, application programs continue to route data to the queue using the original symbolic name; however, this name is now an indirect queue that refers to the new symbolic name. Because indirect queues are established by using transient data resource definitions, the application programmer does not usually have to be concerned with how this is done. Further information about transient data resource definition is in the CICS® Resource Definition Guide.
