This section addresses the following problems you might encounter during uninstallation.
The Java ES installation program places the uninstaller on your system at the following location:
Solaris OS: /var/sadm/prod/SUNWentsys4
Linux: /var/sadm/prod/sun-entsys4
If the uninstaller is not in this directory, one of the following might have occurred:
Java ES was never installed on this host.
The Java ES uninstaller previously removed all components and itself from this host.
During uninstallation, if the uninstaller detects that there are no Java ES components on a host, it uninstalls itself.
During a failed installation, one of the following occurred:
The uninstaller was never installed on the host.
The uninstaller was removed, but some Java ES components remain on the host.
Suggested Fix. Manually clean up your system as described in Uninstallation Fails, Leaving Behind Files.
If manual cleanup is necessary because the uninstaller left behind files or processes, perform the following procedure to remove packages from your system.
Determine which packages you want to remove.
Compare the packages on your system with the Java ES packages listed in Chapter 5, List of Installable Packages, in Sun Java Enterprise System 2005Q4 Installation Reference. You can use the Solaris pkginfo or prodreg utility or the Linux rpm command to determine which packages are installed. (See Installation Fails Due to Leftover Files During Uninstallation
Stop all running processes for Java ES components.
Brief instructions for stopping processes are contained in Chapter 6, Configuring Components After Installation component documentation.
Back up all custom configuration and user data you plan to use in subsequent installations.
Reviewing Uninstallation Behavior for Java ES Components provides some information on configuration and user data that should be backed up. For more information, refer to the component documentation for each component.
Use the pkgrm or rpm -e command to remove Java ES component packages.
Remove any remaining component directories and their content that you do not plan to use in subsequent installations. If you do plan to use these directories later, move them elsewhere.
Update the product registry file, which is located here:
On Solaris OS: /var/sadm/install/productregistryOn Linux: /var/opt/sun/install/productregistry
The uninstaller uses this registry to determine which components are installed on a host. Both the installer and uninstaller update the product registry upon completion of an installation or uninstallation.
If you manually remove packages rather than using the uninstaller, then you must edit the product registry so it correctly reflects the software installed on your system.
Clean up the log files for your system, which are located here:
Solaris OS: /var/sadm/install/logsLinux: /var/opt/sun/install/logs
The log files might not correctly reflect the state of your system after you manually remove packages.
During uninstallation, the uninstaller uses the product registry file to determine what needs to be uninstalled:
On Solaris OS: /var/sadm/install/productregistryOn Linux: /var/opt/sun/install/productregistry
If the uninstaller fails, you might need to retry after you restore the product registry from your backup copy.
If you manually remove packages, the product registry is not automatically updated. When you subsequently run the uninstaller, you might encounter problems because the product registry does not correctly reflect your system. In this case, you can try to reinstall and then run the uninstaller again.
