Service registration allows processes, such as an Oracle database, to identify their available services to the listener, which then acts as a portmapper for those services. The value for this parameter is typically obtained from the combination of the DB_NAME and DB_DOMAIN parameters (DB_NAME.DB_DOMAIN) in the initialization parameter file, but the value can also contain any valid name used by clients to identify the service.
