Overview

A WebLogic Server cluster is a group of servers that work together to provide a more scalable, more reliable application platform than a single server. The WebLogic Server EJB container supports clustering services. Load balancing and failover for EJBs and RMI objects is handled using special, replica-aware stubs, which can locate instances of the object throughout the cluster. You create replica-aware stubs for EJBs and RMI objects by specifying the appropriate deployment descriptors or providing command-line options to rmic.

When you deploy a clustered object, you deploy it to all the server instances in the cluster (homogeneous deployment). You can deploy the clustered objects to a target cluster by choosing the server instances in the cluster from the Targets tag in the Administration Console.
