7.3.3.1 Running the Deinstallation Tool From an Oracle Home

You can run the deinstallation tool from an Oracle home or from the software installation media.

  1. The default method for running the deinstallation tool is from the deinstall directory in the Oracle home as the Oracle Installation user:
    C:\> %ORACLE_HOME%\deinstall\deinstall.bat
  2. Provide information about your servers as prompted or accept the defaults.
The deinstallation tool stops Oracle software, and removes Oracle software and configuration files on the operating system.

Example 7-1 Running deinstall.bat From Within the Oracle Home

The most common method of running the deinstallation tool is to use the version installed in the Oracle home being removed. The deinstallation tool determines the software configuration for the local Oracle home, and then provides default values at each prompt. You can either accept the default value, or override it with a different value. If the software in the Oracle home is not running (for example, after an unsuccessful installation), then the deinstallation tool cannot determine the configuration, and you must provide all the configuration details either interactively or in a response file. To use the deinstallation tool located in the current Oracle home directory, issue the following commands while logged in as a member of the Administrators group:

C:\> app\oracle\product\12.2.0\dbhome_1\deinstall\deinstall.bat

Provide additional information as prompted.

Note:

When using the deinstallation tool from a location other than within the Oracle home being removed, you must specify the -home option on the command line.
