Oracle Database for z/OS views all client connections to the database as network connections, even when the client and server are on the same system and no real network is involved. This means virtually all Oracle client-server interactions work the same way whether the client is local or remote, and neither client applications nor the server being accessed are aware of the distinction. Applications can be developed and tested with a local server and then deployed, unchanged, to a production environment with a remote server (or vice versa). Similarly, a production database server or a production client environment can be moved from one system to another with minimal disturbance.
