How Do I Uninstall Oracle 11g Server?

Published in Database Administration 2 mins read

Uninstalling Oracle 11g server involves a few steps, but it's generally a straightforward process. Here's a guide:

1. Prepare for Uninstall

  • Backup Your Data: Before uninstalling, back up all your critical data and configurations. This ensures you can restore them if needed.
  • Stop All Oracle Services: Stop all Oracle services related to your 11g instance. This includes the listener, database services, and any other related services.
  • Check for Dependencies: Ensure there are no other applications relying on your Oracle 11g server. If there are, address these dependencies before proceeding.

2. Run the Deinstallation Script

  • Locate the Deinstallation Script: The deinstallation script is usually located in the Oracle home directory (e.g., $ORACLE_HOME/deinstall/deinstall.sh for Linux/Unix).
  • Execute the Script: Open a terminal or command prompt and navigate to the directory containing the script. Run the script with appropriate permissions.

3. Confirm Successful Uninstall

  • Check for Remaining Files: After the deinstallation script completes, check if any Oracle files remain in the Oracle home directory. Remove any leftover files.
  • Verify Services: Ensure all Oracle services are stopped and no longer running.
  • Remove Oracle Home Directory: Delete the entire Oracle home directory (e.g., /u01/app/oracle/product/11.2.0/dbhome_1) to fully remove Oracle 11g.

4. Additional Considerations

  • Silent Uninstall: You can use a silent uninstall option for automated deinstallation. Refer to Oracle documentation for specific commands and options.
  • Oracle Universal Installer (OUI): While the script is usually sufficient, you can also use OUI for manual deinstallation. This provides a more interactive approach but is generally less efficient.

5. Post-Uninstall Steps

  • Clean Up System: Remove any temporary files or directories created during the installation process.
  • Update System: Consider updating your operating system to ensure compatibility with other software.

This guide provides a general overview of the uninstall process. For detailed instructions specific to your environment, consult the Oracle documentation for your version of Oracle 11g.
