Configure non-durable subscribers

 

We can set the non-durable subscriber queue name property in either of the following ways:

• Use the WebSphere MQ JMS administration tool (for JNDI retrieved objects) to set the BROKERSUBQ property

• Use the setBrokerSubQueue() method in your program

For non-durable subscriptions, the queue name you provide should start with the following characters:

• SYSTEM.JMS.ND.

To select a shared queue approach, specify an explicit queue name, where the named queue is the one to use for the shared queue. The queue that you specify must already physically exist before you create the subscription.

To select the multiple queue approach, specify a queue name that ends with the * character. Subsequently, each subscriber that is created with this queue name creates an appropriate dynamic queue, for exclusive use by that particular subscriber. MQ JMS uses its own internal model queue to create such queues. Therefore, with the multiple queue approach, all required queues are created dynamically.

When you use the multiple queue approach, we cannot specify an explicit queue name. However, we can specify the queue prefix. This enables you to create different subscriber queue domains. For example, you could use:

• SYSTEM.JMS.ND.MYDOMAIN.*

The characters that precede the * character are used as the prefix, so that all dynamic queues that are associated with this subscription have queue names that start with SYSTEM.JMS.ND.MYDOMAIN.
