How does a server listen to a socket?
Server sockets listen on a port, and clients try to connect. When a connection is received from a client, server creates another socket (when server.Accept () returns on a blocking socket). The return value of that accept call is also a socket, and that is what you should use to communicate with the client.
How to create a port listener in Windows?
To have a port listener on a specific port in Windows, you can use the “Port Listener” utility. This utility is available for free for Windows 95 to Windows 10. In the above example, I have started listening port on 5500, and it’s time to validate if it’s running. Open a command prompt and run netstat to validate if port 5500 is listening

Supported services, that is, the services to which the listener forwards client requests, can be configured in the listener.orafile or this information can be dynamically registered with the listener. This dynamic registration feature is called service registrationand is used by Oracle9ior Oracle8iinstances.

Where is the listener configuration stored in Oracle?
The listener configuration is stored in a configuration file named listener.ora. Because all of the configuration parameters have default values, it is possible to start and use a listener with no configuration. This default listener has a name of LISTENER, supports no services upon startup, and listens on the following TCP/IP protocol address:
Which is the listening Protocol address for a listener?
The LISTENERentry defines the listening protocol address for a listener named LISTENER, and the SID_LIST_LISTENERentry provides information about the services supported by the listener LISTENER. Figure 12-1 Example listener.ora File
