Rolling back product updates

You can uninstall product updates and optional new features that you have installed using Rational® Product Updater.

  1. Log on to your system with the same user account used to install your Rational software development product.

    Restriction: On Windows® operating systems, this account requires Administrator privileges. On Linux® operating systems, you must use the root user account.

  2. Start Rational Product Updater:
    • On Windows operating systems, click Start > Programs > IBM Rational > Rational Product Updater.
    • On Red Hat Enterprise Linux 3.0, open the main menu and click Programming > Rational Product Updater.
    • On SuSE Linux Enterprise Server 9.0 (GNOME desktop environment), open the main menu and click Applications > Programming > Rational Product Updater.
    • On SuSE Linux Enterprise Server 9.0 (K Desktop Environment), open the main menu and click IBM Rational > Rational Product Updater.
    An inventory of installed products is displayed.
  3. Click the Rollbacks tab. The Rollbacks page opens and displays an inventory of updates and optional features that are currently installed for all Rational software development products.
  4. Click on an update or optional feature to display its description and detailed information. Review this information to determine if you want to uninstall the update or optional feature.
  5. Select the check box beside each update and optional feature that you want to roll back. Dependencies between updates will be automatically enforced. If you select to roll back an update that is required by other updates you have installed, the updates that depend upon it will automatically be selected to be rolled back as well. If the check box beside a product update or optional feature is not available it means that it is not possible to roll it back. This happens for the following reasons:
    • The update was designed so that it cannot be rolled back.
    • The update was designed so that it cannot be rolled back if multiple products share the Rational Software Development Platform.
    • The cleanup operation has been run.
    • The update has a dependent update that cannot be rolled back.
    Note: When Product Updater rolls back an update, it deletes the files for that update from your system. Therefore, if you roll back an update and later decide to reinstall the update, Product Updater will need to download the update from the update site again when it is reinstalled.
  6. Click the Roll Back Updates button to uninstall the selected updates. A dialog will display to show the progress of the rollback.

    If the Rational Software Development Platform is running you may be prompted to stop it. Click OK to close the dialog box. When you stopped the Rational Software Development Platform, return to the Product Updater and click Roll Back Updates.

    Note: You may be prompted to stop the Rational Software Development Platform when it is not running.  This can happen if it was stopped abnormally. If this happens, restart the Rational Software Development Platform and stop it normally. See Handling messages to stop the Rational Software Development Platform when it is not running for more information.
When the rollback completes, a message confirming the success of the operation appears in the top pane of the Product Updater window and the updates and optional features that were removed no longer appear in the list of installed products.

When product updates or optional features are rolled back, they are completely removed from your system. You can, however, reinstall them from the update site or optional feature site using the Product Updater tool.
