Abstract

A system and method for scheduling software updates on data processing systems. In an embodiment, software updates are scheduled on a data processing system by identifying a list of software updates; scheduling at least one primary software update for execution within a scheduled outage time based on an estimated execution time and an estimated rollback time for the at least one primary software update; executing the at least one primary software update during the scheduled outage time; and ordering the list of software updates for possible execution of at least one secondary software update in any remaining outage time in dependence upon the estimated execution times and estimated rollback times for each of the remaining software updates. The list of software updates may also be ordered in further dependence upon evaluation of relative priorities between the software updates, any prerequisite software updates, and a performance scaling factor for the data processing system.

Claims

1. A method of scheduling software updates on a data processing system, comprising:

identifying a list of software updates;

scheduling at least one primary software update for execution within a scheduled outage time based on an estimated execution time and an estimated rollback time for the at least one primary software update;

executing the at least one primary software update during the scheduled outage time; and

ordering the list of software updates for possible execution of at least one secondary software update in any remaining outage time in dependence upon the estimated execution times and estimated rollback times for each of the remaining software updates.

2. The method of claim 1, further comprising ordering the list of software updates in dependence upon evaluation of relative priorities between the software updates, and any prerequisite software updates.

3. The method of claim 2, further comprising adjusting the estimated execution times and rollback times with an estimated performance scaling factor in dependence upon the type of data processing system.

4. The method of claim 3, further comprising recording metrics for executing the software updates and storing the metrics in a knowledge base, the recorded metrics including at least one of actual execution time, actual rollback time, and configuration information for the type of data processing system on which the software update was executed.

5. The method of claim 4, further comprising:

evaluating the metrics stored in the knowledge base; and

in dependence upon the evaluation, updating at least one of the estimated execution time, rollback time, and performance scaling factor for subsequent evaluation and ordering of the software updates.

6. A system for scheduling software updates on a data processing system, comprising:

means for identifying a list of software updates;

means for scheduling at least one primary software update for execution within a scheduled outage time based on an estimated execution time and an estimated rollback time for the at least one primary software update;

means for executing the at least one primary software update during the scheduled outage time; and

means for ordering the list of software updates for possible execution of at least one secondary software update in any remaining outage time in dependence upon the estimated execution times and estimated rollback times for each of the remaining software updates.

7. The system of claim 6, further comprising means for ordering the list of software updates in dependence upon evaluation of relative priorities between the software updates, and any prerequisite software updates.

8. The system of claim 7, further comprising means for adjusting the estimated execution times and rollback times with an estimated performance scaling factor in dependence upon the type of data processing system.

9. The system of claim 8, further comprising means for recording metrics for executing the software updates and storing the metrics in a knowledge base, the recorded metrics including at least one of actual execution time, actual rollback time, and configuration information for the type of data processing system on which the software update was executed.

10. The system of claim 9, further comprising:

means for evaluating the metrics stored in the knowledge base; and

means for updating at least one of the estimated execution time, rollback time, and performance scaling factor in dependence upon the evaluation, for subsequent evaluation and ordering of the software updates.

11. A data processor readable medium storing data processor code that when loaded into data processing device adapts the device to schedule software updates, the data processor readable medium comprising:

code for identifying a list of software updates;

code for scheduling at least one primary software update for execution within a scheduled outage time based on an estimated execution time and an estimated rollback time for the at least one primary software update;

code for executing the at least one primary software update during the scheduled outage time; and

code for ordering the list of software updates for possible execution of at least one secondary software update in any remaining outage time, in dependence upon the estimated execution times and estimated rollback times for each of the remaining software updates.

12. The data processor readable medium of claim 11, further comprising code for ordering the list of software updates in dependence upon evaluation of relative priorities between the software updates, and any prerequisite software updates.

13. The data processor readable medium of claim 12, further comprising code for adjusting the estimated execution times and rollback times with an estimated performance scaling factor in dependence upon the type of data processing system.

14. The data processor readable medium of claim of claim 13, further comprising code for recording metrics for executing the software updates and storing the metrics in a knowledge base, the recorded metrics including at least one of actual execution time, actual rollback time, and configuration information for the type of data processing system on which the software update was executed.

15. The data processor readable medium of claim 14, further comprising:

code for evaluating the metrics stored in the knowledge base; and

code for modifying at least one of the estimated execution time, rollback time, and performance scaling factor in dependence upon the evaluation, for subsequent evaluation and ordering of the software updates.
