From the websphere mq 6.0 manual:

Configuring durable subscribers:
For durable subscriptions, the queue name you provide must start with the following characters:
SYSTEM.JMS.D.
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. |
Does any one else know if i can create multiple topics on my already created queue SYSTEM.JMS.D.CIM?
Thanks,
Shane. |
Let's introduce you to a little bit of pub/sub lingo.
You NEVER create a topic on a queue.
You may subscribe a queue to one or more topics.

shavo, some basics about the publish subscribe messaging paradigm in mq land.
pubsub messaging in wmq land is an abstraction built up on top of the point to point queue based infrastructure.
You dont create a topic explicitly, instead you register your interest in a topic by subscribing to it and the topic will appear.
When dealing with pubsub, for the most part you dont need to worry about what queues to use. The broker/client will assign default values for all this.
Additionally, if you want control you can go to the extent of creating a subscription to a topic and have it assigned a certain queue, notice i said subscription, not topic.
I would highly recommend that you pause whatever project you are working on and go through the "Writing WebSphere MQ JMS publish/subscribe applications" section of the "Using Java" manual.
