Configuring the List of Oracle Listeners per Instance (4302491)

Use the Listeners view in the Databases Administration dashboard to edit the list of monitored listeners per instance, by adding or removing listeners from the list.

To add listeners to an instance

1. Open the drop-down list below the title Please select an agent:, to display the entire list of selected agents.
   IMPORTANT: As RAC agents whose version is earlier than 11G2 have no listeners, they are not included in the list, even if such agents appear in the list of selected agents.
2. Select a single agent from the list.
3. Click Add Listener.
   The contents of the Add a Listener dialog box that appears now vary between Windows and UNIX. For instructions for Windows-based agent, go to Step 4.
   In UNIX, enter a listener service name in the designated field.
4. For a Windows-based agent, type data in the following fields:
   • Listener name — the name of the listener
   • TNS Admin — the path of the $TNS_ADMIN directory (usually $ORACLE_HOME/network/admin)
5. Click Add.
   The newly added listener appears in the Listeners table. 

To edit the properties of a single listener:

1. Select the requested listener from the table.
2. Click Edit Listener.
3. In the Edit a Listener dialog box, edit the existing data in the various fields (see Step 4 of the procedure for adding a listener).
4. Click Set to apply the changes or Cancel to revert to the previous settings.

To stop monitoring a listener:

1. Select the requested listener from the table.
2. Click Delete Listener.
   The Stop Monitoring a Listener dialog box opens.
3. Click Yes to confirm the deletion or Cancel to keep monitoring the listener.
4. At the bottom of the view, click Save changes.
