Adding a cluster to a bus without using messaging engine policy assistance
You can add a cluster as a member of a service integration bus without using messaging engine policy assistance. One messaging engine with default properties is created for the cluster. After you add the cluster, you can create more messaging engines and you can create and configure new core group policies to customize the way that the messaging engines are managed.
Before you begin
About this task
When you add a server cluster as a member of a bus without using messaging engine policy assistance, one messaging engine is created for the cluster. The messaging engine uses the default SIBus core group policy with default properties, such that the messaging engine can fail over to any server in the cluster.
After you add the cluster, you can customize the configuration. You can create more messaging engines and you can create and configure new core group policies to customize the way that the messaging engines are managed. To do this, you must know how to create and configure a core group policy for messaging engines, and know how to use match criteria to associate a messaging engine with a core group policy.
Use the following procedure if you are already familiar with this procedure. Otherwise, use messaging engine policy assistance.
You can optionally tune the initial and maximum Java™ virtual machine (JVM) heap sizes. Tuning the heap sizes helps to ensure that application servers hosting one or more messaging engines are provided with an appropriate amount of memory for the message throughput you require.

If security is enabled, and the bus has mixed-version bus members, the bus members establish trust by using an inter-engine authentication alias. If you add a server cluster as a bus member at WebSphere Application Server Version 6, and it is the first bus member at this level, you must select or create an authentication alias during this task. This action sets the inter-engine authentication alias.
