Hi

this website/forums are really good and only thing I think missing is the section for a very important featur about Pub/Sub. so thot of startinga new topic and have a question too

Publications are sent to a stream queue for publications
SYSTEM. BROKER. DEFAULT. STREAM by default

Subscriptions are sent to the brokerâ€™s control queue for registering the subscriber
- SYSTEM. BROKER. CONTROL. QUEUE

how does the Publisher gets registered with the Broker and where are these messages sent

later

The Publishers are registered automatically the first time they publish a message. Or you can send a command message to the control queue, like a subscriber.

When Publisher publishes a publication the broker distribute it to all the Temporary queue created by Subscriber. For example if you are doing Non durable subscription then you will see Temprory queues such as SYSTEM.JMS.ND.* these are the queues where you will see messages for a subscriber.

These Temporary dynamic queues are created by Subscriber at the time of registration.

Hope this helps.

Hey Scott
Thanks for the reply..I have one more query...
the way we explicitly register and deregister subscribers do we have to explicitly de-register the Publisher too ??

You need to send a "Deregister Publisher" command message.

Chapter 7 of the Publish / Subscribe User's Guide has all the command message parameters and such.

Regards,
Scott
