to 80
Oracle is one of the leading relational database management systems in the world, used by many organizations for its robust features and powerful performance. However, like any other software, it requires configuration and maintenance to ensure optimal functioning. One such configuration is changing the default port from 8080 to 80. In this article, we will discuss the steps to successfully change the Oracle port and the potential benefits of doing so.
First, let's understand why changing the port is necessary. By default, Oracle uses port 8080 for its HTTP connections. This port is commonly used by other applications and can lead to conflicts, resulting in performance issues. Moreover, port 80 is the standard port for web traffic, and changing Oracle's port to 80 can improve the server's accessibility and make it easier to integrate with other web-based applications.
Now, let's dive into the steps to change the Oracle port. The process involves modifying the listener.ora file, which contains the network configuration information for the Oracle database. This file can be found in the ORACLE_HOME/network/admin directory. Once located, open the file in a text editor and look for the following line:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 8080))
)
)
Here, replace 8080 with the desired port, in this case, 80. Save the changes and restart the listener service for the changes to take effect. You can also verify the changes by running the command 'lsnrctl status' in the command prompt. If the listener is running, it will display the new port number.
However, changing the port for the listener is not enough. We also need to update the Oracle Enterprise Manager (EM) Console to reflect the new port. To do so, navigate to the ORACLE_HOME/network/emd folder and locate the emd.properties file. Open it in a text editor and look for the following lines:
agentPort=1830
agentUrl=http\://hostname\:8080/emd/main/
Here, replace 8080 with the new port number, i.e. 80. Save the changes and restart the EM agent service for the changes to take effect.
It is essential to note that changing the Oracle port may also require changes in the firewall and any other network settings. Ensure that the new port is open and accessible for incoming connections.
Now, let's talk about the benefits of changing the Oracle port to 80. As mentioned earlier, port 80 is the standard port for web traffic, and most firewalls and routers are configured to allow traffic on this port. By changing the Oracle port to 80, we can avoid any potential conflicts and improve the server's accessibility. Additionally, integrating with other web-based applications becomes more seamless, making it easier to share data and resources.
In conclusion, changing the Oracle port from 8080 to 80 is a simple yet crucial configuration that can significantly improve the server's performance and accessibility. By following the steps mentioned above, you can successfully change the port and reap the benefits of doing so. However, make sure to test the new configuration thoroughly to ensure that everything is functioning correctly.
