Part 1 will discuss the fundamental aspects of clustering JMS resources such as queues, topics, and connection factories, and illustrate the steps to go through to configure a clustered destination in a WebLogic cluster. Part 2 will discuss JMS clustering in the context of several design and configuration strategies that demonstrate how to create efficient and optimized JMS architectures. WebLogic v7.0 introduced JMS clustering. This article will discuss the fundamental aspects of JMS clustering in WebLogic 8.1 (SP3). Clustering JMS ResourcesScalability, high availability, and fault tolerance are required of mission-critical systems.

In Part 1 of this article series we discussed the fundamental aspects of clustering JMS resources in a WebLogic cluster. In Part 2 we will discuss JMS clustering in the context of design and configuration strategies that demonstrate how to create efficient JMS architectures.

Such a configuration, for example, would call for little consideration to the location of JMS and JDBC resources since clients that need to ac... (more)
