How WebSphere(R) MQ Publish/Subscribe relates to WebSphere MQ

WebSphere MQ Publish/Subscribe is a function of WebSphere MQ. The broker runs on WebSphere MQ for AIX(R), HP-UX, iSeries(TM), Linux(R), Windows(R), and Solaris. It uses standard WebSphere MQ facilities (but note that it does not support message groups or segmented messages).

You can have one broker on each WebSphere MQ queue manager. The broker uses the same name as the queue manager.

Applications can be written with standard WebSphere MQ programming techniques, using the Message Queue Interface (MQI) or the Application Messaging Interface (AMI).

Publishers and subscribers do not have to be on the same machine as a broker. They can reside anywhere in the network, provided that there is a route from their queue manager to the broker. So, for example, you could have a publisher on z/OS(R) and a subscriber on Solaris.
