Steps to completely uninstall oracle 11g

Why can't oracle be easily uninstalled today if something goes wrong.

1. Disable all oracle services. You can disable it in the windows Service Manager;

2. Open the Registry: regedit open path: <find Registry: Start-> Run-> regedit>

HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \

Delete all service names starting with oracle in this path. This key identifies various services registered by Oracle in windows.

My deletion operations include:

3. Open the registry and find the path:

HKEY_LOCAL_MACHINE \ SOFTWARE \ ORACLE

Delete the oracle directory where the software installation information of the Oracle database is registered.

4. Delete the registered oracle Event Log and open the Registry

HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Eventlog \ Application

Delete all items starting with oracle in the registry.

5. Delete the oracle content in the environment variable path.

Right-click my computer> Properties> advanced> environment variable> PATH variable.

Delete the content of Oracle in this value. Note: A Bunch Of Operating System directories are recorded in the path. In windows, directories are separated by semicolons (;). Note the following when deleting directories.

Suggestion: I feel that all the paths containing apps are oracle-related. Let's delete them.

6. Restart the operating system.

Above 1 ~ After completing the five steps, restart the operating system.

7. After the operating system is restarted, all Oracle-related processes will not be loaded. Delete all data under Oracle_Home.

(Oracle_Home refers to the installation directory of the Oracle program)

8. Delete the oracle directory under C: \ Program Files.

(This directory depends on the path of Oracle Installation)

9. Delete oracle items under the Start Menu, such:

C: \ Documents and Settings \ All Users \ Start Menu \ Program \ Oracle-Ora10g

The installation directory varies slightly.

If you do not delete the Oracle-related menu directories under the Start menu, it does not affect the re-installation of Oracle. This menu will be replaced when Oracle is re-installed.
