    1. Creating a TNS Listener.
    Install Oracle Net Listener software on the server.
    Define a listener in a file (on Unix/Linux) or in a file (on Windows).
    Start the listener using the Oracle Net Configuration Assistant (NetCA) or by executing the following command:
      lsnrctl start LISTENER_NAME.
    2. Configuring TNS Entries.
    On the client side, create a TNS entry in a file or use the Net Configuration Assistant (NetCA) to add a new entry.
    The TNS entry should include the following information:
      host: The host name or IP address of the server.
      port: The port number on which the listener is running.
      service name: The name of the service defined in a file.
    Example:
      `(DESCRIPTION =。
        (ADDRESS = (PROTOCOL = TCP)(HOST = oracle-server)(PORT = 1521))。
        (CONNECT_DATA =。
          (SERVICE_NAME = XE)。
        )。
      )`。
    3. Testing the TNS Configuration.
    Use the tnsping utility to test the TNS configuration:
      tnsping DATABASE_NAME.
    If the test is successful, you will see a response similar to the following:
      TNS Ping Successful.
      OK (100 msec)。
