Hi
I am new to Pub Sub model.

for Pub sub I have created username server on configuration queue manager.
but I am not getting how to add users for differen topics.
please help.

Also for publishing message I am using
MQinput --> Comput --> Publication node.

Inside Compute node setting MQRFH2 properties with suitable topics and users e.g Set OutputRoot.MQRFH2.psc.Topic='News/Politics';

for subscription I am using

MQinput--> Compute --> MQoutput

Inside compute node I am giving Queue manager and Queu name on which I am expecting message as a Set SET OutputRoot.MQRFH2.psc.QName='SUBQ';

So here I should get message on Queue SUBQ on local queue manager.
Please correct my flow if its wrong.

thanks,
santy

In pub/sub, the publisher doesn't know anything about the subscribers, including what queues they want to use.

The publisher just produces messages and gives them to the broker for publication.

The broker then determines if anyone has registered a subscription to the topic, and which queues those subscribers registered, and then delivers the message.

And please take Jeff's post as an occasion to review the pub/sub section of the broker manual. You'll find enough links to the manual for me not to post another one...

Enjoy
