Sun Java Enterprise System 5 Installation Guide for UNIX

Installation Fails Due to Removed Shared Components in Product Registry After Uninstallation

As of the Java ES 5 release, shared components are listed in the product registry file after installation.

The Java ES uninstaller removes product components from the system but does not remove shared components. After an uninstallation, the product registry still contains entries for the shared components. If you manually remove any Java ES shared components after an uninstallation, these components are not removed from the product registry. Thus, the next Java ES 5 installation fails because the installer assumes that the manually deleted shared components are present (because they still have entries in the product registry file).

Tip –

Avoid manually removing Java ES shared components from your system.

Suggested Fix. Either remove the corresponding entries from the product registry file or remove the product registry file itself. Removing entries from the product registry file can cause the file to become corrupted, so you might prefer to remove the whole product registry. Before doing this, verify that products other than Java ES components are not using the product registry file.

On Linux and HP-UX there is no equivalent of the graphical product registry that exists on Solaris OS. If you manually removed files on Linux or HP-UX, you must manually edit the product registry file to remove those entries.
