A method and apparatus for providing high availability of a database. A first front end server is coupled to a first back end server, and a second front end server is coupled to a second back end server. The second front end server provides redundancy to the first front end server and the second back end server provides redundancy to the first back end server. The front end servers function as a gateway into the database and comprise protocol services for processing input/output requests to the gateway. The back end servers comprise database protocol services and interface directly to the gateway to retrieve information requested by the processed database requests received from the front end servers.
