WebSphere Application Server Continuous Queue Cluster

190
The following diagram shows one example of a cluster configuration on the IBM
WebSphere Application Server.
The diagram is an example of a continuous queue integration bus configuration
in a cluster of three application servers. To gain the benefit of multi-server
processing within a cluster, each member of the cluster needs to be configured
with its own message engine.
The processing occurs when the integration framework receives enterprise service
messages by using the HTTP, EJB (Enterprise JavaBeans), and SOAP actions. The
load balancer directs the enterprise service messages to an application server,
which then places the message into the continuous queue. Each application server
in the cluster places messages into its own message store.
Enterprise service messages that are sent using the Data Import feature process
messages into the application server queue store, which limits the processing to a
single server.
