Load Balancing

For information on how to configure RMI/IIOP for multiple application server instances in a cluster, Chapter 11, RMI-IIOP Load Balancing and Failover, in Sun Java System Application Server 9.1 High Availability Administration Guide.

When tuning the client ORB for load-balancing and connections, consider the number of connections opened on the server ORB. Start from a low number of connections and then increase it to observe any performance benefits. A connection to the server translates to an ORB thread reading actively from the connection (these threads are not pooled, but exist currently for the lifetime of the connection).
