Oracle 10 Listener Configuration Guide

Oracle 10 is a popular database management software used by businesses and organizations around the world. One important aspect of using Oracle 10 is configuring the listener, which is responsible for receiving and managing client requests to connect to the database. In this article, we will provide a guide for configuring the listener in Oracle 10.

Step 1: Check Current Listener Status

Before configuring the listener, it’s important to understand its current status. To do this, open a command prompt on the server where the Oracle 10 database is installed and enter the command:

lsnrctl status

This will show you the current status of the listener, including its name, version, and status.

Step 2: Edit Listener.ora File

The listener.ora file is the configuration file for the listener. It can be found in the $ORACLE_HOME/network/admin directory. To edit the file, use a text editor such as Notepad or vi. Here is an example of what the file might look like:

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
    )
  )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = orcl)
      (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
    )
  )

In this example, the listener is named “LISTENER” and it is configured to listen on the hostname “hostname” on port 1521. The “SID_LIST_LISTENER” section lists the database instances that can be accessed through the listener. In this case, there is one instance named “orcl.”

To add a new instance, simply add another “SID_DESC” section with the appropriate information.

Step 3: Start Listener

To start the listener, use the command:

lsnrctl start

This will start the listener process, which will begin accepting client connections to the database.

Step 4: Test Listener

Once the listener is started, it’s important to test it to make sure it’s functioning properly. To do this, use the command:

tnsping 

Replace “” with the name of your listener (in this example, “LISTENER”). This command will check the connectivity between the client and the listener.

Step 5: Troubleshooting

If there are any issues with the listener, it’s important to troubleshoot them to ensure proper functionality. One common issue is endpoint resolution, which can occur if the hostname or port number in the listener.ora file is incorrect. Another issue is a firewall blocking client connectivity to the listener.

To troubleshoot these issues, check the listener log file (located in the $ORACLE_HOME/network/log directory) for error messages. You can also use the command “lsnrctl status” to check the current status of the listener.

Configuring the listener in Oracle 10 is an important step in making sure your database is accessible to clients. By following these steps and troubleshooting any issues that arise, you can ensure that your listener is functioning properly and accepting client connections to the database.
