Introduction
WebLogic clustering is a highly recommended configuration for production environments.
The WebLogic cluster provides reliability and high availability by distributing the requests
and the load to the WebLogic Server instance members of the cluster.
Using WebLogic cluster also facilitates the administration tasks because WebLogic Server
automatically distributes the configuration and deployment changes to all WebLogic Server
instances, including the distribution of the deploy file to all machines.
