Database Oracle Expert One-on-One: Oracle: Part 2 Tutorial

I was working on a project recently where they decided to use only the latest, greatest technologies: everything was coded in Java with EJBs. The client application would talk to the database server using beans ? no Net8. They would not be passing SQL back and forth between client and server, just EJB calls using Remote Method Invocation (RMI) over Internet Inter-Orb Protocol (IIOP).

If you are interested in the details of RMI over IIOP you can refer to http://java.sun.com/products/rmi-iiop/ .

This is a perfectly valid approach. This functionality works and can be extremely scalable. The people responsible for the architecture understood Java, EJBs, the protocols involved ? all of that stuff. They felt they were in a strong position to successfully build such a project. When their application would not scale beyond a couple of users they decided that the database was at fault and severely doubted Oracle's claim to be the 'most scaleable database ever'.
