To configure a messaging engine to prefer a server or group of servers, configure a core group policy, which is used to...

• identify server components
• define how they will behave within a cell or cluster

For the greatest throughput of messages...

1. Create a cluster bus member with messaging engines running on every server in the cluster.

2. Define the queue or queues being used on the cluster bus member.

3. Ensure that message production to the queue is workload-managed across the cluster:
   • Install an EJB or servlet application on the cluster and have that application produce the messages. Workload management of the client calls to the application workload manages the message production across the cluster.

   • Produce messages from clients connected to messaging engines outside of the cluster. The bus can then workload manage the messages across the cluster.

4. Install an MDB application on the cluster to consume the queue messages.
