Queue manager QM2 example for IBM® i
The following object definitions allow applications connected to queue manager QM2 to retrieve request messages from a local queue called PAYROLL, and to put replies to these request messages to a queue called PAYROLL.REPLY on queue manager QM1.
You do not need to provide a remote queue definition to enable the replies to be returned to QM1. The message descriptor of the message retrieved from local queue PAYROLL contains both the reply-to queue and the reply-to queue manager names. Therefore, as long as QM2 can resolve the reply-to queue manager name to that of a transmission queue on queue manager QM2, the reply message can be sent. In this example, the reply-to queue manager name is QM1 and so queue manager QM2 requires a transmission queue of the same name.
All the object definitions have been provided with the TEXT attribute and are the minimum required to make the example work. The attributes that are not supplied take the default values for queue manager QM2.
