Creating clusters in WebSphere Application Server
In the Integrated Solutions Console,
you can create as many clusters as your deployment requires. Each
cluster can consist of two or more Java™ virtual
machine (JVM) cluster members.
Configuring Java Message Service for WebSphere Application Server
Java Message Service
(JMS) is the messaging standard that is used to send and receive messages
from queues. This process enables distributed communication with external
systems in a loosely coupled, reliable, and asynchronous manner. The
JMS configuration is application server-specific. You must configure
JMS queues within the environment and make them accessible through
the Java Naming Directory Interface
(JNDI).
