Uninstallation Overview

The Sun Cluster Geographic Edition uninstaller might behave differently depending on which component products you installed and how they are interrelated. Remember the following when running the uninstaller:

• The uninstaller must be run separately on each host that contains Sun Cluster Geographic Edition components.

• The uninstaller only removes component products that were installed by the Sun Cluster Geographic Edition installer.

• The uninstaller does not check product dependencies for the system.

• The uninstaller might remove configuration and user data files.

You can remove the Sun Cluster Geographic Edition software without stopping applications or data replication.
