Clustered JNDI

WebLogic Server provides cluster-wide JNDI services to support deployment of objects in a clustered environment. Whenever you add a WebLogic Server instance to a cluster, the server's JNDI tree is merged with that of the cluster and the merged JNDI tree is propagated automatically to all members of that cluster. To reduce the potential network traffic due to the replication and synchronizing of the JNDI tree, WebLogic Server lets developers specify which objects of the JNDI tree the server must replicate to the cluster JNDI tree. You can do this by specifying the REPLICATE_BINDINGS property for the initial context factory, weblogic.jndi.WLInitialContextFactory. Of course, the fewer the objects you specify for replication, the fewer the load balancing and failover capabilities the server will have.
