Create a Listener

A listener must exist on the server in order for the database to receive connections. You can create a listener with one or more listening protocol addresses. Clients using connect descriptors configured with one of these protocol addresses can send a database connection request to the listener.

To create a listener:

1. Select Listener configuration in the Welcome page, and then choose Next.

   The Listener Configuration, Listener page appears.

2. Select Add, and then click Next.

   The Listener Configuration, Listener Name page appears.

3. Accept the listener name provided in the Listener Name field, or edit the field with another name, and then choose Next.

   The Listener Configuration, Select Protocols page appears.

   By default the listener name is LISTENER for the first listener. Subsequent listener names are defaulted to LISTENERn. The listener name must be unique any given node.

4. Select the protocols from the Available Protocols list, and then choose the right-arrow button.

5. Order the protocols according to which protocols you expect clients to use the most with the up- or down-arrow buttons, and then click Next.

   The page appropriate for the selected protocol appears.

6. Enter the appropriate protocol parameters for the chosen protocol in the fields provided, and then click Next.

   The Listener Configuration, More Listeners? page appears.

   If configuring the listener to listen on TCP/IP, choose the default port of 1521 to use dynamic service registration. If you do not, you must configure the LOCAL_LISTENER parameter in the initialization parameter file and resolve the listener name through a naming method.

    

   See Also: Chapter "Configuring and Administering the Listener" in the Oracle Net Services Administrator's Guide for further information about configuring nondefault port numbers in the listener.ora file

7. Select No if you have completed listener configuration, and then Next.

   The Listener Configuration Done page appears.

   Or, select Yes to configure another listener, and then choose Next to repeat steps 3-7.

8. Click Next to acknowledge the Listener configuration complete! message.
