SQQMName (character string)

This determines whether or not the messages in a queue-sharing group are put onto a locally-defined shared queue, or directly onto the target queue.

The value is one of the following:

• USE: messages are delivered to the ObjectQMgrName before being put onto the target queue. This is the default value. It ensures that when a queue manager is migrated from a previous version the function remains unchanged.

• IGNORE: messages are put directly onto the shared queue by any queue manager in the same queue-sharing group as the ObjectQMgrName.

By putting a given message directly onto its target queue in a queue sharing group, WebSphere MQ does not have two execute two puts and a get. This feature decreases the workload in a queue sharing group (the decrease in workload could be even bigger, where messages are being transmitted over channels).

To determine the value of this attribute, use the MQIA_SQQMNAME selector with the MQINQ call.
