An external procedure is a function that is written in the C programming language and stored in a shared library on the server. For an Oracle database to connect to an external procedure, configure the listener.ora file with a protocol address and external procedure service information.

Note: Net8 Configuration Assistant configures this information in the listener.ora file during an Oracle8i installation.

To configure external procedures 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 Listening Locations..

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

5. Select IPC for the protocol and enter extproc for the key value.

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

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

8. Enter exproc in the Program Name field, plsextproc in the SID field, and the Oracle home directory in the Oracle Home Directory field.

9. Ensure the server is configured with a connect descriptor to access the external procedures, as described in Configure a Connect Descriptor for External Procedures.

10. Choose File > Save Network Configuration.
