Oracle7 Server Distributed Systems Volume I: Distributed Data
Functionally, gateway security is identical to that of an Oracle7 Server, as described in Oracle7 Server Concepts. For SQL-based transparent gateways, Oracle7 database security is mapped to the native data dictionary of the data source. For file-based transparent gateways, the Transparent Gateway Utility is used to administer gateway users, roles, privileges, tables, and views.
