Uninstalling your InfoSphere MDM instance

Use this procedure to uninstall the full InfoSphere® MDM product instance.

Before you begin

If you are planning to later reinstall this InfoSphere MDM runtime environment and use the same database instance that it uses, make sure that you create a backup image of the database as a precaution.

In the environment that you want to uninstall, stop each runtime InfoSphere MDM instance (operational server, entity manager instance, client application, and so on).

About this task

Using the IBM® Installation Manager uninstall option removes the entire offering. If you want to remove only selected components (for example, Inspector or Data Steward UI), use the modify option.

Procedure

Optional: If you used the Configure_MasterDataManagement madconfig script to separate the installation and configuration, then you must run another madconfig script to clean up the configuration files:
- On Microsoft Windows systems, run
```
madconfig.bat Uninstall_MDM
```
- On Linux or UNIX systems, run
```
madconfig.sh Uninstall_MDM
```
Important: Be careful when running the Uninstall_MDM madconfig script. Running Uninstall_MDM removes the configuration of all features, and not just the configuration of a particular component.
Start IBM Installation Manager and click Uninstall.
Select the InfoSphere MDM package and click Next.
Review the summary information and click Uninstall.
Click Finish.

What to do next

The uninstall process does not remove the composite bundle archive (CBA) from the internal bundle repository. You must manually remove the CBA in IBM WebSphere® Application Server Integrated Solutions Console (admin console).
