Java ES provides an uninstallation program for removing components that were installed on your system using the Java ES installer. Like the Java ES installer, the uninstaller can be run in graphical, text-based, or silent mode.
During installation, the Java ES installer places the Java ES uninstaller at the following location:
Solaris OS: /var/sadm/prod/SUNWentsys4
You can use the optional -no parameter to run the uninstaller without uninstalling any software. This option is useful for familiarizing yourself with the uninstaller and for creating a state file for a subsequent silent uninstallation.
Like the Java ES installer, the uninstaller can be run in graphical, text-based, or silent mode.
The uninstaller only removes components that were installed by the Java ES installer. To remove components that were not installed by the Java ES installer, follow instructions in the component documentation.
The uninstaller must be run separately on each host that contains Java ES components. Remote uninstallation is not supported. For each host, you can select one or more components for removal.
The uninstaller does not remove Java ES shared components.
The uninstaller might remove configuration and user data files. The files vary for each component.
After the uninstallation process is completed, you might have to remove some additional files and directories. For product-by-product information, refer to Reviewing Uninstallation Behavior for Java ES Components.
The uninstaller checks component dependencies only for the system on which the uninstaller is running, issuing warnings when a dependency is discovered.
The uninstaller does not unconfigure installations on third-party web containers.
The uninstaller does not unconfigure Access Manager SDK installations on any web container. You must reconfigure the web container manually (for example, restore the original classpath).
Do not use the uninstaller to remove Sun Cluster software unless Sun Cluster software was installed but never used to configure a cluster node. For more information, see Uninstalling Sun Cluster Software
The uninstaller might behave differently depending on which components you installed and how they are interrelated.
The uninstaller recognizes dependencies among products that are installed on the same host. If you attempt to uninstall a component that has dependent products installed on the host, the uninstaller issues a warning.
For example, if you attempt to uninstall Access Manager from the host where Portal Server is also installed, the uninstaller warns you that Portal Server cannot function without Access Manager.
In most cases, you can uninstall a component if no other component depends on it.
For example, Portal Server depends on Access Manager but Access Manager does not depend on Portal Server. If you attempt to uninstall Portal Server, the uninstaller does not issue a warning because Access Manager can function without Portal Server.
When uninstalling a component, you must identify which products are configured for that component (some additional configuration might be required). Otherwise, you could have components on your system that are configured to support products that are no longer present.
The uninstaller does not recognize the following interdependencies:
Dependencies from remote hosts
Dependencies resulting from configuration
Some component dependencies can be satisfied with components deployed on remote hosts. The uninstaller does not recognize these dependency relationships.
For example, if you uninstall Directory Server, the uninstaller does not warn you that Access Manager depends on Directory Server, even if both products are deployed on the same host. This is because another Directory Server instance on yet another host could support Access Manager.
The uninstaller does not recognize a component dependency that is the result of postinstallation configuration.
For example, suppose you install both Portal Server and Calendar Server on the same host, and then configure Portal Server to use Calendar Server for the Portal Server calendar channel. After this configuration, Portal Server depends on Calendar Server. However, if you then uninstall Calendar Server, the uninstaller does not warn you that Portal Server depends on Calendar Server because the uninstaller does not know about the postinstallation configuration.
