Review the examples to help you understand how to run the deinstallation tool.
If you perform a deinstallation by running the setup.exe command with the -deinstall option from the installation media, then help is displayed unless you enter a -home flag and provide a path to the home directory of the Oracle software to remove from your system.
Use the optional flag -paramfile to provide a path to a response file.
In the following example, the setup.exe command is in the path \directory_path, where directory_path is the path to the database directory on the installation media, and C:\app\oracle\product\12.2.0\dbhome_1 is the path to the Oracle home which is removed:
DRIVE_LETTER:\> cd \directory_path DRIVE_LETTER:\> setup.exe -deinstall -home C:\app\oracle\product\12.2.0\dbhome_1
The following example uses a response file in the software owner location C:\Documents and Settings\oracle\:
DRIVE_LETTER:\> cd \directory_path DRIVE_LETTER:\> setup.exe -deinstall -paramfile C:\Documents and Settings\oracle\my_db_paramfile.tmpl
