Title: Installing software updates in an order that takes into account the down time caused by an update failing
Inventor: KIKUCHI SHINJI
IPC: G06F9/445
Filed: 2011-12-23
Abstract: A data processing system provides services based on a service level agreement. When updating the software on the system, the time a service is unavailable due to an update is calculated. The time required to recover from a failed update is also calculated. The cost of the service being unavailable for the sum of the times is then calculated. If there are multiple updates, the updates are installed in an order, which minimizes this cost. Calculating the cost may take into account whether there is a user using the service, when the update is applied. If an update of a piece of software fails, then updates for software with similar attributes may be prevented.
