To remove an IBM® InfoSphere® Information Server product module from your installation, run the InfoSphere Information Server software removal program on each computer that contains components of the product module.
To deactivate an IBM InfoSphere DataStage® edition or feature pack (for example, if you are no longer entitled to an item), you do not use the IBM InfoSphere Information Server software removal program. Instead, deactivate them by using the LicensingServiceAdmin tool. Refer to Activating entitled IBM InfoSphere DataStage editions and feature packs.
Depending upon the product modules that you select, you might not have to run the software removal program for all tiers. Not all product modules have components on all tiers. You only need to run the program on the tier computers that contain components for the product modules. You can skip tier computers that do not contain components for the product modules. If you run the program on a computer that does not contain components for the product modules, no components are removed.
| Product module | Tier computers on which to run the installation program |
|---|---|
| IBM InfoSphere FastTrack | Services, Client |
| IBM InfoSphere Metadata Workbench | Services, Engine |
| IBM InfoSphere Business Glossary | Services, Client |
| IBM InfoSphere Business Glossary Anywhere (requires InfoSphere Business Glossary). The client is installed separately. | Services |
| All others | All tier computers |
The installation program only removes the appropriate software for the tiers on a computer. You can run the software removal program on all of the computers in your configuration, and select all tiers each time. The removal program determines automatically which tiers exist on each computer and removes the appropriate components.
Run the program on the computers in the following order:
Client, if the product modules you are removing require changes to this tier.
The client tier software removal can take place at any point in the sequence.
Engine, if needed. Refer to the table to determine whether you need to run the software removal program on the engine tier.
Services. All product module removals require changes to the services tier.
Metadata repository, if the product modules you are removing require changes to this tier.
If you preinstalled the database system for the metadata repository tier and configured the databases within the database system by using the scripts that are supplied with the installation media, the software removal program does not remove the database system.
For example, to remove InfoSphere Information Analyzer, first run the software removal program on the engine tier computer. Then run it on the services tier computer. Lastly, run the program on the metadata repository tier. You can run the software removal program on the client tier computers at any point in the sequence.
You only need to run the software removal program one time on each computer even if the computer hosts more than one tier. The installation program removes the tier components in the correct order on the computer.
If you remove all product modules that require a particular tier, the tier is also removed. For example, in a system that includes InfoSphere DataStage and InfoSphere Business Glossary, if you remove InfoSphere DataStage, the entire engine tier is removed because InfoSphere Business Glossary does not require it.
If a failure occurs, restore your installation from your backup.
