Patent abstract

A net traffic optimization method provides for clients and servers to communicate with each other over a busy network. Each client process will make an Oracle database service request that is recognized by a listener process in the servers. As each database instance comes up, it generates a globally unique instance identifier (“UII”). Each UII remains valid as long as the database instance that generated it is running. The same UII identifier is given to every client needing a connection to that particular instance. Client processes can simultaneously or sequentially connect to database instances, and must never see the same UII being used to identify two different instances.
