How can I use clusters?
Typically a cluster contains queue managers that are logically related in some way and need to share some data or applications. For example you might have one queue manager for each department in your company, managing data and applications specific to that department. You could group all these queue managers into a cluster so that they all feed into the PAYROLL application. Or you might have one queue manager for each branch of your retail store, managing the stock levels and other information for that branch. If you group these queue managers into a cluster, they can all access the same set of SALES and PURCHASES applications, which are held centrally, perhaps on the head-office queue manager.
Once a cluster has been set up, the queue managers within it can communicate with each other without extra channel definitions or remote-queue definitions.
You can convert an existing network of queue managers into a cluster or you can establish a cluster as part of setting up a new network.
A WebSphere MQ client can connect to a queue manager that is part of a cluster, just as it can connect to any other queue manager. See the WebSphere MQ Clients book for more information about clients.
