JMS queue    A staging area that contains messages that have been sent and are waiting to be read. Note that, contrary to what the name queue suggests, messages have to be delivered in the order sent A JMS queue only guarantees that each message is processed only once.

The major components of the WebLogic JMS Server architecture, as illustrated in the figure below.

*(A) JMS servers that can host a defined set of modules and any associated persistent storage that reside on a WebLogic Server instance.

*(B) JMS modules contains configuration resources (such as queues, topics, and connections factories) and are defined by XML documents that conform to the weblogic-jmsmd.xsd schema.

*Client JMS applications that either produce messages to destinations or consume messages from destinations.

*(E) WebLogic persistent storage (file store or JDBC-accessible) for storing persistent message data.

The following figure illustrates the WebLogic JMS architecture.

A Node Manager process is not associated with a specific WebLogic domain but with a

machine. You can use the same Node Manager process to control server instances in

any WebLogic Server domain, as long as the server instances reside on the same

machine as the Node Manager process. Node Manager must run on each computer

that hosts WebLogic Server instances—whether Administration Server or Managed

Server—that you want to control with Node Manager.
