Q34: Where can I find the uninstaller?

Answer: When you expand the Java ES distribution bundle, you will not find the uninstall utility because it does not yet exist on your host. During installation, the Java ES installer places the uninstaller in the following location:

• Solaris OS: /var/sadm/prod/SUNWentsys5

• Linux and HP-UX: /var/sadm/prod/sun-entsys5

If you do not see the uninstaller at this location, two possibilities exist:

• Java ES software has not been installed on the host.

• All Java ES software has been uninstalled. (After all product components are uninstalled, the uninstaller removes itself from the host.)

Before performing an uninstallation, you must understand component uninstallation behavior. See Reviewing Uninstallation Behavior for Java ES Product Components in Sun Java Enterprise System 5 Installation Guide for UNIX. Not all product components behave in the same way during uninstallation.

To perform uninstallation, see Chapter 8, Uninstalling, in Sun Java Enterprise System 5 Installation Guide for UNIX.

To run the uninstaller without uninstalling any software, use the uninstall -no command. The -no option is useful for familiarizing yourself with the uninstaller or for creating a state file for a subsequent silent uninstallation.

Q35: What can be uninstalled with the Java ES uninstaller?

Answer: The Java ES uninstaller removes only product components that were installed by the Java ES installer. You must use the version of the uninstaller that was placed on your host during initial Java ES installation.

You cannot use the uninstaller to remove shared components. When you install a new version of Java ES, the shared components are automatically upgraded to correct versions by the installer. If you need to manually uninstall shared components, refer to the Sun Java Enterprise System 5 Upgrade Guide for UNIX.

You cannot use the uninstaller to remove Sun Cluster software unless the Sun Cluster software has never been configured.

To remove components that were not installed by the Java ES installer, follow instructions in the documentation for that component.

Before uninstalling, you must be familiar with the following information in the product documentation:

• Impact of uninstaller limitations. See How the Uninstaller Works in Sun Java Enterprise System 5 Installation Guide for UNIX.

• Uninstaller behavior as it affects the product components. See Reviewing Uninstallation Behavior for Java ES Product Components in Sun Java Enterprise System 5 Installation Guide for UNIX.

• The overall process for performing uninstallation. See Chapter 8, Uninstalling, in Sun Java Enterprise System 5 Installation Guide for UNIX.

Q36: How do I know if my Java ES uninstallation succeeded?

Answer: One way to determine if the uninstallation succeeded is to compare the packages listed in the installation log with the packages listed in the uninstallation log. You can also check the product registry to verify that Java ES components have been removed. See Q40: What is the product registry and why should I care about it?

In some cases, the uninstaller does not remove all of the packages or directories. You might not discover this situation until you try to do a new Java ES installation. If this occurs, check the appropriate troubleshooting write ups for guidance on removing files or components that are left behind. See Resolving Uninstallation Problems in Sun Java Enterprise System 5 Installation Guide for UNIX.
