Database Links and Oracle Transparent Gateways

An Oracle Transparent Gateway provides access to non-Oracle data and services, such as cooperative server connectivity to IBM DB2 through a transparent gateway.

Once a gateway is installed, Oracle7 client applications can access the non-oracle data as if it were data in Oracle tables. To do so, a system administrator creates database links and local synonyms at each integrating server for the gateway server. Database links and synonyms provide location transparency. They are created on the Oracle7 Servers that integrate the transparent gateway into the Oracle7 cooperative server environment.
