Starting and Stopping the Listener

The Oracle listener is set to start automatically whenever the host is restarted. However, when your system encounters unforeseen circumstances, or when you have manually stopped the listener, you can restart it with Database Control or at the command line.

To stop the listener with Database Control:

On the Database Home page, under General, click the Listener link.

The Listener page appears.
Click Stop.
Enter the host credentials, if you did not configure Preferred Credentials, then click Login.
On the Start/Stop Listener page, click OK to perform the specified action or Cancel to quit.

To start the listener with Database Control:

On the Database Home page, under the heading General, click the Listener link.

The Listener page appears.
Click Start.
On the Start/Stop Listener page, click OK.

After a couple of minutes, a confirmation message appears, indicating that the listener has been started.

Note: If you have just stopped the listener and are still at the Database Control Listener page, then you will not see a Start button. You must go to the Database Home page, wait a minute or two, and then return to the Listener page.

To start or stop the listener at the command line:

Open a command window.
Follow the steps listed in "Configuring the Operating System Environment Variables".
Enter either of the following commands, depending on whether you want to start or stop the listener:
```
lsnrctl start
lsnrctl stop
```
