Appendix D. Uninstalling your DB2 product

Uninstalling your DB2 product (Windows)

This task provides steps for completely removing your DB2 product from your Windows operating system. You should only perform this task if you no longer require existing your DB2 instances and databases.

If you are uninstalling the DB2 default copy, and you have other DB2 copies on your system, you should use the db2swtch command to choose a new default copy before you proceed with the uninstallation. Also, if your database administration server (DAS) is running under the copy being removed, you should move your DAS to a copy that is not being removed. Otherwise, you will have to recreate the DAS using db2admin create command after the uninstall and you might have to reconfigure the DAS for some functionality to work.

Procedure:

To remove your DB2 product from Windows:

1.Drop all databases. You can drop databases using the Control Center or drop database command. 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.

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 to remove your DB2 product. Using this command, you can uninstall multiple DB2 products at the same time using the /p parameter. You can also silently uninstall DB2 products by using /u parameter which will remove the DB2 products specified in the response file. 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 should ONLY be attempted if the above 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.
