2.7 Searching the CORBA Naming Service by using the round-robin policy

You can look up the EJB home objects or business interface references with the same names (optional name) registered in multiple CORBA Naming Services by following the round-robin policy. This is called the round-robin search.

When you perform a round-robin search for the EJB home objects or business interface references using the relevant names from the JNDI name space, the client application can acquire the EJB home objects or business interface references selected by the round-robin policy from the EJB home objects or business interface references that exist in multiple CORBA Naming Services. As a result, you can distribute the load out by starting the J2EE server in a cluster configuration. Furthermore, you can invoke the Enterprise Beans of the J2EE server from the EJB client regardless of the cluster configuration.

The following table describes the organization of this section.

Hint
Note that to perform a round-robin search, the EJB home objects or business interface references to be searched must be registered with the same names in the CORBA Naming Service. Therefore, use the user-specified name space functionality to specify the same names for the EJB home objects or business interface references.
