## Oracle8i Custom Installation

If, within a Custom install, you choose the JServer option (as shown in Figure 3-1), the Database Configuration Assistant configures an MTS database for session-based IIOP connections, using non-SSL TCP/IP.

Note: If you choose the Typical or Minimal options within the custom choices, your configuration is the same as defined in "Oracle8i Typical or Minimal Installation".

#### Figure 3-1 Choosing the JServer option

This places the following line within your database initialization file:

    mts_dispatchers="(protocol=tcp)(presentation=oracle.aurora.server.SGiopServer)"

If, instead, you installed the Advanced Security Option and you want the SSL-based TCP/IP connection, edit your database initialization file to remove the hash mark (#) from the following line:

    mts_dispatchers="(protocol=tcps)(presentation=oracle.aurora.server.SGiopServer)"

Note: The (`protocol=tcps`) attribute identifies the connection as SSL-enabled.

After the installation is complete, you must bring up the Net8 Assistant to configure the listener for IIOP connections.

#### Net8 Assistant

The Net8 Assistant can modify any of the listener settings. The following is a brief description of the task you must do to configure the listener through the Net8 Assistant. For a fuller explanation, see the Net8 Administrator's Guide.

1. Start Net8 Assistant

   - On UNIX, run `netasst` at `$ORACLE_HOME/bin`.

   - On Windows NT, choose Start > Programs > Oracle - HOME_NAME > Network Administration > Net8 Assistant.

2. In the navigator pane, expand Local > Listeners.

   This brings you to the listener location panel, as shown in Figure 3-2.

   #### Figure 3-2 IIOP Listening Port Configuration

3. Select a listener.

4. From the list in the right pane, select Listening Locations.

5. Select the TCP/IP or TCP/IP with SSL protocol from the Protocol list.

6. Enter the host name of the database in the Host field.

7. Enter port 2481 in the Port field if the chosen protocol is TCP/IP, or enter port 2482 if the chosen protocol is TCP/IP with SSL.

8. Click "Dedicate this endpoint to IIOP connections".

9. Choose File > Save Network Configuration.

This places the following within your `listener.ora` file:

    listener=

    	(description_list =

    		(description=

       			(address=(protocol=tcp)(host=sales-server)(port=2481))))

    			(protocol_stack=

    				(presentation=GIOP)

    				(session=RAW)

    			)

    		)

    	)

After configuration, the client directs its request to a URL that includes the host and port, which identifies the listener, and either the SID or database service name, which identifies the database. The following shows the syntax for this request:

    session_iiop://<hostname>/:<portnumber>/:<SID | service_name>
