Oracle 10: Configuration and Activation of Listener

Oracle Database 10g is a popular database management system extensively used in enterprises for a variety of applications. In order to access the database, we need to configure and activate a listener, which provides a network service to enable database connections. In this article, we will discuss how to configure and activate the listener in Oracle 10.

Before we proceed with the configuration process, let’s understand the basics of the listener. The listener is an executable program that runs on the database server to manage incoming client connections to the database. It listens on a defined port and accepts connections from clients using the Oracle Net Services protocol.

Now, let’s discuss the steps to configure and activate the listener in Oracle 10.

Step 1: Start the Oracle Net Configuration Assistant

The Oracle Net Configuration Assistant is a graphical tool used to configure network-related settings for Oracle Database. To start the tool, navigate to the ORACLE_HOME/bin directory in the command prompt and type the following command:

$ netca

This will launch the Oracle Net Configuration Assistant.

Step 2: Create a Listener

In the Oracle Net Configuration Assistant, select “Listener Configuration” and then click the “Add” button to create a new listener. Provide a name for the listener and specify a port number for the listener to listen on. By default, the listener listens on port 1521.

Step 3: Set Listener Parameters

After creating the listener, select it from the list of avlable listeners and then click the “Edit” button to set the listener parameters. Here, we can configure various listener parameters such as the protocol used, the network address, and the services offered by the listener.

Step 4: Start the Listener

After setting the listener parameters, click the “Start” button to start the listener. The listener will now be active and listening for incoming connections on the specified port.

To verify that the listener is working properly, we can use the lsnrctl command-line tool provided by Oracle. To check the status of the listener, type the following command in the command prompt:

$ lsnrctl status

This will display the status of the listener and the services it is offering.

In conclusion, configuring and activating the listener is an essential step in setting up an Oracle Database. By following the steps outlined in this article, we can easily configure and activate the listener in Oracle 10. This will enable clients to connect to the database and perform various operations using the Oracle Net Services protocol.
