An integrated component that provides the generic technology for accessing non-Oracle systems from the Oracle database server. Heterogeneous Services enables you to:
Use Oracle SQL to transparently access data stored in non-Oracle systems as if the data resides within an Oracle server.
Use Oracle procedure calls to transparently access non-Oracle systems, services, or application programming interfaces (APIs), from your Oracle distributed environment.
To initiate a connection to the non-Oracle system, the Oracle8i database starts an agent process through the listener on the gateway. In order for the Oracle8i database to connect to the agent, the server must be configured with a net service name to access the agent and the listener must be configured with service information about the agent.
