Removing outdated files

Rational® Product Updater can remove from your system any files that become outdated after you install a new update.

When the Product Updater tool installs an update, previous versions of the superseded files are not overwritten; they remain on your file system. This is required in order for Product Updater to be able to roll back the update. However, this also means that disk space is used to store both the new and previous versions of files.

To reduce the disk space used by the installed products, you can purge their outdated files using the Product Updater's Clean Up function.

Important: If you run Clean Up, you will not be able to roll back any of the currently installed updates for any of the installed products.

To cleanup outdated files:

  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 Clean Up.
  4. A dialog box warns you that you cannot roll back any of the currently installed updates after cleaning up. Click Continue.
When the cleanup completes, a message confirming the success of the operation appears in the top pane of the Product Updater window. The Clean Up button is disabled, and on Rollbacks page, rollback will be disabled for all updates and optional features.
