The integration framework can provide integration services across a cluster of application servers. If the continuous queue on a single server is inadequate for your message volume, you can add central processing units, hardware, and a cluster configuration to improve message processing performance.
When you implement a server cluster, you can use multiple servers simultaneously to process inbound messages. These messages are processed in the continuous queues by using message-driven beans (MDBs). Cluster configurations facilitate the processing of messages in large volumes.
