DB2 Version 9.7 for Linux, UNIX, and Windows

Uninstalling your DB2 product (Windows)

If you are uninstalling the default DB2 copy, and you have other DB2 copies on your system, use the db2swtch command to choose a new default copy before you proceed with the uninstallation. Also, if your DB2 Administration Server (DAS) is running under the copy being removed, move your DAS to a copy that is not being removed. Otherwise, re-create the DAS using the db2admin create command after the uninstall, and you reconfigure the DAS for some function to work.

To remove your DB2 product from Windows:

1. (Optional) Drop all databases using the Control Center or drop database command. Be sure that you no longer need these databases. If you drop your databases, all of your data will be gone.
2. Stop all DB2 processes and services. This can be done through the Windows Services panel or by issuing the db2stop command. If DB2 services and processes are not stopped before attempting to remove your DB2 product, you will receive a warning containing a list of processes and services that are holding DB2 DLLs in memory. If you will use Add/Remove Programs to remove your DB2 product, this step is optional.
3. You have two options for removing your DB2 product:

   Add/Remove Programs

   Accessible through the Windows Control Panel, use the Add/Remove Programs window to remove your DB2 product. Refer to your operating system's help for more information about removing software products from your Windows operating system.

   db2unins command

   You can run the db2unins command from the DB2DIR\bin directory to remove your DB2 products, features, or languages. Using this command, you can uninstall multiple DB2 products at the same time using the /p parameter. You can use a response file to uninstall DB2 products, features, or languages using /u parameter. For more information, see the db2unins command topic.

Unfortunately, your DB2 product cannot always be removed by using the Control Panel - Add/Remove Programs facility or using the db2unins /p command or the db2unins /u command. The following uninstallation option must ONLY be attempted if the previous method fails.

To forcefully remove all DB2 copies from your Windows system, run the db2unins /f command. This command will perform a brute force uninstallation of ALL DB2 copies on the system. Everything except user data, such as DB2 databases, will be forcefully deleted. Before running this command with the /f parameter, see the db2unins command for details.
