Uninstalling NuoDB on Windows

The process for uninstalling NuoDB differs depending on which package (EXE or ZIP) was used to install NuoDB.

Uninstalling a NuoDB EXE Package

You can use the Uninstall a program facility of Windows to uninstall NuoDB:

Start the Windows Control Panel
Under the Programs section choose Uninstall a program
Locate NuoDB in the list of software and right-click on it
Choose Uninstall to start the uninstall wizard

Alternatively you may start the uninstall wizard from the command line by running %NUODB_HOME%\uninstall.exe :

%NUODB_HOME%\uninstall.exe

The wizard will ask if you want to delete or preserve the configuration and log files:

winuninstall configuration

You can request that the uninstaller proceed silently without asking any questions. Command line parameters available for uninstall.exe are:

Parameter Description

Parameter	Description
`/keepdata=true`	Preserve the configuration and log directory (this is the default).
`/keepdata=false`	Delete the configuration and log directory during uninstallation.
`/S`	Run the uninstaller silently. No graphical wizard will be started and no questions will be asked. This parameter is case-sensitive (must be uppercase).

/keepdata=true

Preserve the configuration and log directory (this is the default).

/keepdata=false

Delete the configuration and log directory during uninstallation.

/S

Run the uninstaller silently. No graphical wizard will be started and no questions will be asked. This parameter is case-sensitive (must be uppercase).

Uninstalling a NuoDB ZIP Package

To uninstall a NuoDB ZIP package first ensure that all NuoDB processes are stopped. Then, uninstall the NuoDB Admin Process (AP) service:

%NUODB_HOME%\etc\nuoadmin.bat stop

%NUODB_HOME%\etc\nuoadmin.bat uninstall

Then the installation directory can be removed:

rmdir /S /Q %NUODB_HOME%

The default location for configuration and log files is within the installation directory for ZIP packages. The above rmdir operation will also delete these files.
