You want to know if WebSphere Message Broker (WMB) can benefit from WebSphere MQ facilities, such as clustering for scaling and failover.
Resolving the problem
The Brokers are, in effect, WebSphere MQ applications, and therefore, they can automatically benefit from new features provided by WebSphere MQ.
For example, the queues that the Brokers read messages from can be clustered WebSphere MQ queues. If WebSphere MQ clustering is used, it would allow many brokers to be used. Each broker could run one or more message flows, thus permitting high performance throughput. If further growth is required, then more processors, with more brokers and more message flows can be added to the overall system. Furthermore, the ability to run the Brokers on z/OS allows you to take advantage of the power and scalability of that platform. Thus you can scale by upgrading to more powerful processors, as well as by adding more processors.
