Hi all,
I have a very basic question on Pub-Sub of IBM Websphere MQ.
I know that we have to tag queues to subscriptions. Is there a way where we need not have any queues created for subscriptions.
Is it that we have to have a queue associated with each subscription. If so, then what is the advantage that Pub-Sub brings onto table.
Can anyone please explain this. |

How did you come to know that? It's not the case.

The subscriber can select a number of possible delivery options.

No.

The explanation is you don't understand pub/sub properly.
Read, experiment, determine.

Pub/Sub gives you a 1-to-1 and a 1-to-many distribution based upon the Topics and Subscriptions present.
This is all explained in the documentation.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Even if you do decide to "tag" queues to subscriptions, this is still a key advantage.

So can anyone quote an example of subscriber in IIB. How do we define an application to be a subscriber. I mean where do we configure it.
Thanks in advance,
Phani |

You really need to understand the Pub/Sub model better.
maurito gave a good link to a Pub/Sub broker project but your question makes it seem like you still don't understand Pub/Sub.
There is nothing inherent in any application (broker or otherwise) that would let you know it was a subscriber to a publication. This means there is no way to "configure" an application to be a subscriber. |
