Removing IBM InfoSphere Information Server software by using the software removal program

To remove IBM® InfoSphere® Information Server software from your computers, you can run the InfoSphere Information Server software removal program.

You can remove the entire software suite, individual product modules, or individual software tiers.

Attention: Removing the entire software suite, individual product modules, or individual software tiers will result in data loss. Make sure that all file systems and databases are backed up before beginning a software removal.

The first time that you run the software removal program, use graphical mode. The program displays a graphical wizard that prompts you for options. After you complete the wizard, you save your settings in a response file, and then continue using the wizard to complete the software removal. Alternatively, you can exit the program after saving the response file. The next time that you run the program in graphical mode, you can load the settings in your response file instead of specifying them again.

You can also run the program in silent mode. In silent mode, the program uses the settings in a response file and does not display the graphical interface.

Run the software removal program on all target computers, in the following order. If you are removing individual software tiers, the program removes all InfoSphere Information Server product module components that belong to the selected tiers. Also, the program removes all InfoSphere Information Server common components that belong to the selected tiers.

Attention: For client tier removals, you might only want to remove some versions. It is not possible to do this without rendering the remaining versions unusable. Therefore, to remove a particular client tier version from a computer, you first remove the entire client tier from the computer with the software removal program and reinstall the versions that you want.

You run the software removal program only once on each computer even if you are removing more than one tier. The removal program removes the tiers in the correct order. The engine tier is dependent on the services tier, and the services tier is dependent on the repository tier. If more than one tier is installed on a computer, you cannot remove a tier without removing the tiers that are dependent on it.

  1. Client tier

    You can run the removal program on any point in the sequence.

  2. Engine tier

    You must remove the engine tier before you remove the services tier to which it is registered, even if that services tier is on a different computer.

  3. Services tier

    If you installed IBM WebSphere® Application Server by using the installation program, WebSphere Application Server is removed when the services tier is removed.

    If you preinstalled the application server, components that are specific to InfoSphere Information Server are removed. However, the application server is not removed.

  4. Repository tier

    If you installed IBM Db2® by using the installation program, the metadata repository database (and analysis database, if present) are dropped and Db2 is removed.

    If you used the installation program to create the metadata repository database or analysis database in a preinstalled Db2 instance, the databases are dropped. However, Db2 is not removed.

    If you did not create the repository tier by using the installation program, do not use the installation program to remove the repository tier.
