Oracle RMI implementation

Standard TCP load balancing, oc4j uses it's own unique connector which integrates with the HTTP service that runs on top of oc4j, very interesting architecture. So, if you want to load balance oc4j, simply setup your pool using a TCP profile, use persistence if required, which it probably will be, and point your Oracle HTTP server to the VIP address.

 

 

oc4j and Oracle's apache are similar to Apache and mod_jk. You can load balance both of them. Apache would be an HTTP profile, and mod_jk or oc4j would simply be a TCP profile. You could use HTTP profile as well, but not sure if the OC4J protocol will actually work with it. Better safer than sorry, start out with a TCP profile and load balance away.
