Configuring Static Retrieval Load Balancing

To use static retrieval of OC4J instances for load balancing, within each client, configure JNDI properties as follows (see "Using JNDI Properties":

For java.naming.factory.initial, use any initial context factory.
For the java.naming.provider.url, use the ormi:// prefix and a comma separated list of OC4J nodes in the form <hostname>:<port>/<application-name>

For more information, see "Static Retrieval Load Balancing".

Using JNDI Properties

Example 24-4 shows a URL definition that provides the client container with three OC4J nodes (with hostnames s1, s2, and s3 and ports 23791, 23792, and 23793, respectively) to use for load balancing.
