Heterogeneous Services enable you to access a non-Oracle systems from an Oracle8i server. To initiate a connection to a non-Oracle system, the Oracle8i server starts an agent process through the listener on the gateway. Configuration of a Heterogeneous Services for the listener involves creating service information for the Heterogeneous agent.

To configure a Heterogeneous Services for the listener:

1. In the navigator pane, expand Net8 Configuration > Local > Listeners.

2. Select a listener.

3. From the list in the right pane, select Other Services.

4. Choose Add Service. A new Service tab appears.

5. Enter the agent executable in the Program Name field, the agent's Oracle System Identifier (SID) in the SID field, and the executable Oracle home in the Oracle Home Directory field.

6. Ensure the server is configured with a connect descriptor to access the Heterogeneous Service, as described in Configure a Connect Descriptor for External Procedures.

7. Choose File > Save Network Configuration.
