Abstract

A method is described which permits an automatic software update process to be able to recognize and recover from errors that can occur either while the updates are being applied or after they are all applied. Software updates for multiple Licensed Program Products (LPPs) are packaged together on the same distribution media. The user selects LPPs for which he wants to apply updates. Errors can occur while the updates are being applied, or the user may notice an error after the updates have been applied but before they are accepted. In either of the two cases involving errors, the update process needs a general error recovery facility that will return the system to its prior state, i.e., before the update was attempted. For errors that are detected during the update, the recovery should be automatic.
