Ways to thoroughly download Oracle under Windows

Oracle Full Uninstall under Windows:
You can unload a database using Oui, but there will still be some residue in the registry and file system after uninstallation. These residues not only occupy disk space, but also affect

oracle.
  To uninstall Oracle 10g under Windows:
1 Delete the clustered Synchronization service CSS (Cluster Synchronization Services). If the database is configured with automatic storage management ASM, you should remove the CSS service first, because Oracle does not automatically delete the service. Use the Localconfig Delete command under a DOS command to delete the service.
C:\Documents and settings\administrator>localconfig delete
Step 1:  stopping local CSS stack
Step 2:  deleting OCR repository
  failed to open the OCR subkey, err (1060)
  failed to cleanup l Ocal OCR repository
successfully deleted local CSS setup
  Probably because my database does not have ASM configured, so the error message shown above is displayed.
2 stops all Oracle-related services individually. The
 oracle service begins with Ora, for example:

This is a Service dialog box in Windows; Everyone is more familiar with it.

3 Use Oui (Oracle Universal Installer) to uninstall Oracle software.
"Start", "program", "oracle-oradb110g_home1|" Oracle installation product| Universal installer.
Uninstalling Oracle is a long and resource-intensive process, so it's best to close all other program windows before uninstalling. The following window appears.

Select "Yes"

Click "Close" to exit.

5 Delete the ASM instance.
If Oracle is configured with ASM, also manually delete the ASM instance. The following is an example of removing an ASM instance under a DOS command line.
C:\oradim–delete–asmsid +asm
This step is omitted because I did not configure ASM.

6 Delete the registry content.

Run the regedit command to delete the following:

hkey_local_machine| software| Oracle registry key to delete this key.

hkey_local_machine| system| Currentcontrolset| Services, remove all Oracle-led keys under the Services key.

There are no related items found on my system.

hkey_local_machine| system| Currentcontrolset| services| Eventlog| Application, remove all Oracle-led keys under this key.

There are no related items found on my system.

HKEY_CLASSES_ROOT, remove all keys prefixed with ora,oracle,orcl,enumora under this key.

I didn't find the relevant item on my system.

hkey_current_user| software| Microsoft| windows| currentversion| explorer| menuorder| Start menu| Programs, remove all Oracle-led keys under this key.

hkey_local_machine| software| odbc| Odbcinst. INI registry key To remove all key values that have Oracle lettering other than the Microsoft ODBC for Oracle registry key.

Hkey_ I didn't find the relevant item on my system.

local_machine| system| Currentcontrolset| Services, remove the keys prefixed with Oracle or Oraweb.

I didn't find the relevant item on my system.

7 Delete the environment variable.

Delete the value in the environment variable Classpath,path that contains the Oracle typeface.

I didn't find the relevant item on my system.

8 Delete the start | program "also has ORACLE the group and chart of the typeface.

After uninstalling via Oui, my system already has no Oracle groups and charts.

9 last deleted in file system ORACLE related files and directories:

Delete system drive letter: \PROGRM files\oracle directory;

Delete the Oracle_base directory.

I cannot delete the D:\oracle directory and restart the machine before deleting it.

If Oui is installed in a non-default directory, delete this non-default directory;

system drive letter: \ Document and Settings\ user \local Settings\Temp directory to delete temporary files.

At this point, restart the computer immediately.
