Il est parfois difficile de désinstaller correctement une installation Oracle sous Windows.

Nous expliquons ici une méthodologie éprouvée.

 

1. Ensure you are logged in as a user with Administrator privileges.
2. Stop all Oracle services (if any are running):
• Choose Start > Settings > Control Panel > Services.
• If any Oracle services (their names begin with Oracle) exist and have the status Started, select the service and click Stop.
• Click Close to exit the Services window.
3. Start the registry at the MS-DOS command prompt: C:\> REGEDT32
4. Go to HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE and Delete the ORACLE key.
5. Delete any Oracle key under HKEY_LOCAL_MACHINE\SOFTWARE\ODBC.
6. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and remove all keys under here that begin with ORACLE.
7. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \EventLog\Application, and remove all keys under here that begin with ORACLE.
8. Close the registry.
9. Go to Start > Control Panel > System > Environment tab.
10. Click on the system variable path and modify the Path variable.
11. If JRE was installed by Oracle, remove the %ORACLE_HOME%\BIN path and the JRE path. For example, you may see a path similar to this one:
C:\ORACLE\ORA81\BIN;G:\PROGRAM FILES\ORACLE\JRE\1.1.7\BIN
12. Exit the Control Panel.
13. Go to DISK:\WINNT\PROFILES\ALL USERS\START MENU\PROGRAMS.
14. Delete the following icons:
• Oracle - HOME_NAME
• Oracle Installation Products
where HOME_NAME is the previous Oracle home name.
15. Delete DISK:\Program Files\Oracle.
16. Delete all ORACLE_BASE directories on your hard drive.
17. Reboot your computer.
