Uninstalling Oracle Access Manager Components

During Oracle Access Manager component installation, information is saved after certain operations. Until information is saved, you may return and restate details. However, after you are informed that a component is being installed, Oracle Access Manager files are added to the file system.

Note:

If you cancel the installation process after receiving the message that a component is being installed and before completing all procedures, you must restore the system to it's previous condition to remove Oracle Access Manager-related information.

There are several steps you need to complete to remove an Oracle Access Manager component, as outlined in the discussion that follows. Some changes made for Oracle Access Manager are not handled automatically and must be manually removed when the Uninstaller program finishes:

Language Packs: Each installed Language Pack must be removed individually using appropriate file in the component's uninstall directory: Component_install_dir\identity|access\_uninstComponentLP_langtag\uninstaller.exe. For example, suppose you have an Identity Server and the WebPass installed with a Korean Language Pack. After uninstalling the Korean Language Pack on each component host, you must stop and restart both the Identity Server Service and the WebPass Web server instance. This will re-initialize corresponding components with the proper language support. Removing the Language Pack associated with the default Administrator language selected during installation is not supported.

Schema and Data Changes: If Oracle Access Manager will be removed and reinstalled with the same directory instance, only the Oracle Access Manager configuration tree(s) need be deleted. In this case, there is no need to remove the Oracle Access Manager schema from the directory instance. When reinstalling the Identity Server, select ÒNoÓ when asked if you want to update the schema (which is already present). Selecting ÒYesÓ results in an error message "schema already exists".

If, however, you plan to remove and reinstall Oracle Access Manager a different directory instance (or not reinstall at all) then configuration data must be removed manually from the directory server and Oracle Access Manager schema extensions must also be removed using cleanup files provided for your directory server. You must remove data from the Identity Server and Policy Manager.

Depending on the type of directory server, you may have one or two cleanup files. For instance, schema extension cleanup files are provided for user data only for VDS. However schema extension cleanup files are provided for both user data and Oblix (configuration data) for NDS, IPlanet, and Oracle Internet Directory. Schema extension cleanup file names begin with an abbreviation that identifies the type of directory, followed by the type of data to be removed.

As an example, look for the files similar to the following in the Identity Server and Policy Manager installation directories:

• DirectoryName_user_schema_delete.ldif—Oracle Access Manager user data cleanup file for the specific named directory—removes user data that resides on a separate directory instance from configuration data
  
• DirectoryName_oblix_schema_delete.ldif—Oracle Access Manager configuration data cleanup file for the specific named directory—removes both user and configuration data when both reside on the same directory instance
  
• OID_oblix_schema_index_delete.ldif—Oracle Access Manager cleanup file for Oracle Internet Directory only—removes the Oracle Access Manager attribute index from Oracle Internet Directory before or after you use corresponding Oracle Access Manager data and schema cleanup files.
  
• OID_user_index_delete.ldif—Oracle Access Manager cleanup file for Oracle Internet Directory only when a separate instance is used to host user data.
  

Some directory vendors do not provide schema cleanup files. For instance, no such files are provided for ActiveDirectory, and Active Directory Application Mode (ADAM).

Web Server Configuration Changes: Web server configuration changes that occur during installation must be manually reverted after uninstalling the Oracle Access Manager component (WebPass, Policy Manager, WebGate). For example, the ISAPI transfilter will be installed for IIS WebPass. However, when you uninstall WebPass this is not removed automatically. Also, the created Web service extension and the link to the identity directory will not be removed. This type of information must be removed manually. These are examples of information to remove, not a complete list. Further, you must remove any changes that you manually made to your Web server configuration file for the Oracle Access Manager component (WebPass, Policy Manager, WebGate) should be removed.
