We will start this simulation from the DOS prompt. Go ahead and type the lsnrctl command, and press the ENTER key.
The listener control program has started, and you have a prompt. Type in help, and press ENTER, to see a list of valid commands.
As you can see, the help command gets you a brief list of valid Listener Control commands. You can get further help on a command by typing help followed by the command name. Try typing help status, and see what happens.
As you can see, the status command optionally accepts a listener name. You do not need to worry about that now. Just type
status to get a display showing the current status of the listener.
The status display shows you several things, including: the time the listener was started, how long it has been up and
running, what the current trace level is, and the location of the listener parameter and log files. At the bottom you will
see a list of services that this listener is listening for. These usually represent databases. When you are done looking at
the status, type the exit command to exit the Listener Control program.
You are now back at the DOS prompt. This is the end of the simulation.
