Rolling back updates by using wizard mode

Using the rollback feature, you can remove an update to a package and revert to a previous version.

Before you begin

During the rollback process, IBM® Installation Manager must access files from the earlier version of the package. By default, these files are stored on your computer when you install a package. If you change the default setting or delete the files by using the Remove Saved Files option, Installation Manager requires access to your installation repository or media.

To access the Remove Saved Files option, click File > Preferences > Files for Rollback. On the OS X operating system, the Preferences option is under the IBM Installation Manager menu. If you installed the product from a repository, you must list the repository that you used to install the previous version of the product in your preferences. To check the repositories that are listed, click File > Preferences > Repositories. If you installed the product from disks or other media, the media must be available when you use the rollback feature.

About this task

Use the rollback feature to remove an update that you applied to a product package. When you roll back a package, Installation Manager uninstalls the updated resources, and reinstalls the resources from the previous version. You can roll back only one version level at a time.

When you roll back to an earlier version of a package, the package is restored with the same features that are associated with that version. Use the Modify wizard to add and remove features.

For installed fixes, a fix is uninstalled if the fix does not apply to the version of the product that you rolled back to. A fix is not uninstalled if you roll back to a version of the product that the fix applies to.

You cannot roll back Installation Manager to an earlier version.

Procedure

To roll back an updated package:

  1. In Installation Manager, click Roll Back to start the Roll Back wizard.
  2. From the Package Group Name list, select the package group that contains the packages that you want to roll back. Click Next.
  3. Select the version of the package that you want to roll back to. Click Next.

    Some packages require entitlement for updates or fixes. If you did not save files for rollback and you are rolling back to a version that requires entitlement, you must be entitled to the previous version for the rollback to finish. Entitlement is based on your IBM ID credentials. For more information, see IBM ID credentials Help and FAQ. For information about entitlement, see IBM Entitlement Help.

  4. Read the summary information and click Roll Back to roll back the package.

    On Windows, Installation Manager checks for running processes. If processes are blocking the rollback process, the Blocking Processes section includes a list of these processes. You must stop these processes before you continue the rollback process. Click Stop All Blocking Processes. If there are no processes that must be stopped, a list is not shown. The processes must be stopped because these running processes lock files that must be accessed or modified by Installation Manager.
