A dynamic queue is a local WebSphere MQ queue that is created when an application opens a model queue object. A model queue is a queue definition template that sets the attributes of the queue such as the name of the queue and whether it is temporary or permanent.
The MQ Connector component uses dynamic queues in the same way it uses static queues. An application should use a dynamic queue when the following are true:
▪ There is no need to retain the queue after the application terminates.
▪ The responses to the application's messages must be processed by a different application. In this case, the first application creates a reply-to queue that points to the second application.
▪ There is a need to reduce the system administration required for queue configuration and operational management of these queues.
WebSphere MQ automatically deletes a temporary dynamic queue when the application sends a closeConnection call.
The MQ Connector requires the Communications Pool to support dynamic queues. The names of the queues must be unique within the pool.
