Information in this document applies to any platform.


The objective is to deinstall / remove a FMW 11g AS Instance featuring a product which has system ( OPMN managed) components as well as java components and/or an association with a WebLogic Domain. For example:
  • Web Tier
  • Portal / Forms / Reports / Discoverer
  • Identity Management (OID)
The WebLogic Domain has already removed, and now an attempt is made to uninstall / deinstall / remove the remaining system components - the AS Instance - using the Oracle Universal Installer.

The Installer offers two deinstall options
  • Deinstall ASInstances managed by WebLogic Domain
    • Select this option to deinstall a specific Oracle Instance, and its system components that are registered to a WebLogic Domain.
  • Deinstall Unmanaged ASInstances
    • Select this option to deinstall all unmanaged Oracle Instances, and their system components.
The first option does not work because the Installer assumes a "Managed Instance" will have an associated WebLogic Domain. The second screen presented when choosing this option is

"Specify WebLogic Domain Detail Screen"

You cannot specify the details because the WebLogic Domain no longer exists, and therefore you can proceed no further.

The other option "deinstall unmanaged instances" also does not work because after entering the Instance location in the "Specify Instance Location Screen", the Installer reports that the Instance is managed (even though its associated WebLogic Domain has been removed).

How is it possible, then, to remove the AS Instance?
