To modify the port number of the Oracle database, you can follow these steps:<\/p>\n

    \n
  1. Access the listener configuration file for the Oracle database. Locate the listener.ora file in the Oracle database installation directory, usually found under the $ORACLE_HOME\/network\/admin directory.<\/li>\n
  2. Open the listener.ora file and locate the line that contains the port number for the listener. The port number is usually defined in a line similar to the following format:<\/li>\n
  3. LISTENER =
    \n (DESCRIPTION_LIST =
    \n (DESCRIPTION =
    \n (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = port_number))
    \n )
    \n )<\/li>\n
  4. The port_number is the port number of the listener.<\/li>\n
  5. Change the port number to the desired new port number.<\/li>\n
  6. Save the file and then close it.<\/li>\n
  7. Restart the Oracle listener by entering the following command in the command line.<\/li>\n
  8. Stop the listener
    \nStart the listener<\/li>\n
  9. Confirm if the port number change was successful. You can use the telnet command to test if the new port can be connected to.<\/li>\n
  10. Connect to the specified hostname using the new port number with telnet.<\/li>\n<\/ol>\n

    Before changing the Oracle database port number, make sure to backup the data and related configuration files to prevent any accidents that could result in data loss.<\/p>\n","protected":false},"excerpt":{"rendered":"
