Configuring publish/subscribe messaging

In publish/subscribe messaging, the sender of a message (the publisher) is decoupled from the recipient of the message (the subscriber) so that the publisher does not need to know who will receive the message and the subscriber does not necessarily know who sent the message. The publisher publishes the message to the broker, which is then responsible for distributing the message to any subscribers who have registered an interest in the information in the message.

About this task

The way in which you configure publish/subscribe messaging is slightly different for IBM® WebSphere® MQ 6.0 queue managers and for IBM WebSphere MQ 7.0 queue managers.

Although many of the concepts are the same, or similar, certain aspects are different; for example, in Version 7, topics are objects that you can create, edit, and delete but in Version 6, topics are less flexible.
