JNDI and Clustering
From the client's perspective, a WebLogic cluster should appear as one high-performance and fault-tolerant server. This idea carries over to the WebLogic cluster's shared JNDI naming service. The naming service is fault-tolerant because the naming service survives server failures in the cluster. As new servers join the cluster, they automatically participate in the naming service. The naming service is high-performance because each server runs the naming service in parallel, and client requests can be processed on many servers simultaneously.
Replicated Naming Service
Each WebLogic Server maintains its own copy of the cluster's naming service. The advantage of this approach is performance. Each naming service is able to locally ...
