How to Check Linux Version in Oracle?


When it comes to managing Oracle databases on a Linux system, knowing the Linux version is crucial. It not only helps you ensure compatibility but also plays a significant role in troubleshooting and optimizing your Oracle database. In this comprehensive guide, we’ll walk you through various methods to check the Linux version in Oracle, ensuring that you have the expertise and confidence to tackle this essential task.

What is Linux Version in Oracle?

Linux version in Oracle refers to the specific distribution and release of the Linux operating system on which your Oracle database is running. This information helps you understand the environment in which your database operates, allowing you to make informed decisions about configurations, patches, and updates.

Why is it important?

The Linux version in Oracle is essential for several reasons. Firstly, it determines the compatibility of Oracle software with the underlying operating system. Secondly, it influences performance optimization, as certain features or patches may be required for specific Linux versions. Moreover, when encountering issues or seeking support, having this information readily available streamlines the troubleshooting process.


Before we delve into the methods of checking the Linux version in Oracle, let’s ensure you have everything you need:

  • Access to the Oracle database server
  • Basic knowledge of the command line interface
  • Credentials for Oracle SQL and Oracle Enterprise Manager (OEM)

Method 1: Using the Command Line

The command line is a powerful tool for checking the Linux version in Oracle.

Step 1: Open the Terminal

To begin, launch the terminal on your Linux server. You can usually find it in your applications or use the keyboard shortcut Ctrl+Alt+T.

Step 2: Enter the Command

In the terminal, type the following command and press Enter:

lsb_release -a

This command will display detailed information about your Linux distribution, including the version.

Step 3: Interpret the Result

The command will provide information such as Distributor ID, Description, Release, and Codename. The “Release” field will indicate the Linux version.

Now, let’s explore another method.

Method 2: Checking via Oracle SQL

Oracle SQL provides an alternative way to obtain the Linux version.

Step 1: Connect to Oracle Database

Launch your Oracle SQL client and connect to the Oracle database you want to check.

Step 2: Run the SQL Query

Execute the following SQL query:

SELECT * FROM v$version WHERE banner LIKE 'Linux%'

This query will return information about the Linux version on which Oracle is running.

Method 3: Checking via Oracle Enterprise Manager (OEM)

Oracle Enterprise Manager (OEM) offers a user-friendly interface for checking the Linux version.

Step 1: Access OEM

Open your web browser and navigate to the Oracle Enterprise Manager URL provided by your administrator. Log in with your credentials.

Step 2: Navigate to the Server

In OEM, find the server on which your Oracle database is hosted. This usually involves selecting “Targets” and then “Hosts.”

Step 3: Check the Linux Version

Once you’ve located the server, you can find the Linux version information in the system details or server properties section.

Common Errors and Troubleshooting

While checking the Linux version in Oracle, you may encounter some common issues.

Error 1: Connection Issues

If you face connectivity problems, ensure that you have the correct credentials and network access. Check firewall settings if necessary.

Error 2: SQL Query Errors

When running SQL queries, double-check your syntax and ensure you have the necessary privileges. Review Oracle documentation for query troubleshooting.

Error 3: OEM Access Problems

If you can’t access Oracle Enterprise Manager, verify your URL, credentials, and network connectivity. Consult your Oracle administrator for assistance.
