Undoing updates to a system configuration

Use the "Undo updates center" to reverse all updates to a system configuration that have been made according to the customization data of a service instance.

If the updates that are to be reversed have affected the system as well as the sysplex, you have to reverse the updates for both separately. In such a case, the "Undo updates center" panel has a slightly different layout. It is split into two tabbed panels ("System" and "Sysplex") enabling you to perform the necessary steps for both without having to leave the "Undo updates center".

Note

Services that have cross-scope dependencies cannot be updated if msys for Setup Version 1 Release 4 or earlier is running on any of the affected systems. In such a case, you will receive an error message when you attempt to update the service and the "Undo updates center" will not be displayed.


Note that this task not only reverses the most recent update but returns to a state before the very first "Prepare updates" had been done for the service instance. Do "Undo updates" in preparation to removing a product set from a system, for example because you want to remove the product code.

Before you begin:

Steps to display the "Undo updates center" for a service:

  1. In the resource tree, expand the sysplexes folder and the folder for the sysplex you want to work with.
  2. If you want to work with a sysplex-wide service, click the Control panel in the sysplex folder. Otherwise expand the folder for the system you want to work with and click the Control panel in the system folder. A list of available services is displayed in the list view.
  3. In the list view, select the service instance for which you want to undo the updates to the system configuration.
  4. Click File --> Undo system configuration updates...
    Note:
    This menu item is present only if you already have run "Prepare updates" sucessfully for the service instance.

The "Undo updates center" changes its appearance according to the task that has been selected in the task navigation area:
