To configure the Oracle database listener, you need to carry out the following steps:

  1. Open the listener configuration file: Locate the listener.ora file on the Oracle database server. This file is typically found in the ORACLE_HOME/network/admin directory.
  2. Edit the listener configuration file: Open the listener.ora file using a text editor and make sure the following content is present:
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /path/to/oracle_home)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = your_host)(PORT = your_port))
    )
  )

In the configuration above, you need to replace ORACLE_HOME with your Oracle installation directory, your_host with your hostname, and your_port with the port number you want to use.

  1. Start the listener: Input the following command in the command line to start the listener:
lsnrctl start
  1. To verify if the listener has been activated, input the following command to check if the listener has started successfully:
lsnrctl status
  1. Test the connection: Use SQL*Plus or other database tools to connect to the Oracle database and make sure the connection is successful.

By following the steps above, you can successfully configure the Oracle database listener.
