My question is regarding pub/sub. I have read all the documentations available for pub/sub but had a basic question.
I have a publisher application that is publishing a message with a specific topic based on a business event.
I also register subscription through another subscriber application for the specific topic.
Once the subscriber application registers for a topic, can the application stop running.
Is there a way the subscriber application be started (like in a triggered application), when subscribed message comes to the subscriber queue. Because my application is truly event based and we plan to add multiple subscription applications waiting for different topics.
Is the above possible? Have I misunderstood something basic in pub sub concept?
Please help! |

As long as the Queue you are receiving the Subscriptions on isn't a Dynamic Temporary Queue, then yes, you can do what you want.
Once the Subscription is registered, then the application doesn't have to stay active. In fact, you could even split the Registration and the handling of the Subscriptions into 2 programs.
Then, you would use Triggering on the queue where the Publications are delivered to 'fire off' your application whenever one arrived to process it.
Cheers,

Thanks so much. It helps me
So if I have two or more programs subscribing, I will create as many subscriber queues and trigger these programs. |

Yep. For each unique Subscription program, create a seperate Queue and Trigger the program when a message arrives.
Cheers,
