Uninstall and Reinstall an r8.1 SP2 Identity Manager Server on WebLogic 9.2

Important! The following procedure applies in specific situations. Use this procedure to uninstall and reinstall the Identity Manager Server only if you were referred here by Select the Right Upgrade Procedure.

To uninstall and reinstall an r8.1 SP2 Identity Manager Server on WebLogic 9.2

1. Take note of the location from which the IdentityMinder, SiteMinder, and SiteMinderAgent applications were deployed to the cluster.

   The path appears in the WebLogic Admin Console under Deployments, application_name, Overview, Path.

2. Back up all custom code.

   The IdentityManager.ear found in step 1 is the one to back up, not the EAR from the staging area of any managed server.

3. In the WebLogic Admin Console under Deployments, delete the IdentityMinder, SiteMinder and SiteMinderAgent applications.
4. Shut down the weblogic server.
5. On the admin server, delete the IdentityManager.ear, SiteMinder.ear, and SiteMinderAgent.ear folders from the location they were deployed from in r8.1 SP2.
6. On each node, delete the IdentityManager, SiteMinder, and SiteMinderAgent folder from the staging area. They are in the following locations:

   bea\weblogic92\common\nodemanager\servers\server_name\stage\IdentityMinder

   bea\weblogic92\common\nodemanager\servers\server_name\stage\SiteMinder

   bea\weblogic92\common\nodemanager\servers\server_name\stage\SiteMinderAgent

7. Uninstall the Identity Manager Server.

   This step leaves the Identity Manager environments and directories unchanged.

8. If you are using a remote installation of SiteMinder and wish to continue to use it to protect your Identity Manager Environment, perform the following steps:
   1. Run the Identity Manager installer on that host to upgrade the Extensions for SiteMinder.
   2. Configure the Policy Store for CA Identity Manager.

   Note: For more information about installing on a cluster, see the Installation Guide (Weblogic).

9. Reinstall the Identity Manager Server, making sure you take the following actions:
   • If you plan to continue to use SiteMinder, select Connect to Existing SiteMinder Policy Store on the Select Components screen.
   • If you have different database stores for task persistence, workflow, audit, and reports, update the data sources to point to the separate stores.
10. Configure all managed nodes using the Installation Guide procedure. However, in the last step of the Configure Managed Nodes procedure, replace the existing IM_SM_PATH definition line rather than adding a new line at the bottom of the file.

    For example, in WL_HOME\weblogic92\common\bin\commEnv.cmd, the following line points to the old SiteMinder library:

    IM_SM_PATH=%WL_HOME%\common\nodemanager\lib
    

    Replace this line with the following line:

    IM_SM_PATH=%WL_HOME%\common\nodemanager\servers\<server>\stage\IdentityMinder\IdentityMinder.ear\library
    

    This complete path does not exist yet since you have not started the managed node since reinstalling Identity Manager.

11. On the Admin Server, start WebLogic.
12. In the Admin Console, start one managed node.
13. Upgrade the workflow database.
14. Export the Directories and Environments.
15. Migrate the Task Persistence data.
16. Recreate the Identity Manager Directories.
17. Recreate the Identity Manager Environments.

    Reapply all custom code, making sure you reapply all customizations to the cluster.

18. Restart all managed nodes and verify the installation using the cluster section of the Installation Guide.
