Abstract

A computer implemented method, apparatus, and a computer usable program code for managing versioning of a set objects in a network data processing system. A first message is sent to a plurality of data processing systems to cause the plurality of data processing systems to generate delta data for the set of objects on the plurality of data processing systems in the network data processing system in response to a first event. The delta data is stored for each object in the set of objects to form stored delta data, and the stored delta data is subsequently used to return the set of objects to a prior version. A second message is sent to the plurality of data processing systems to cause the plurality of data processing systems to restore the set of objects back to the prior version using the stored delta data in response to a second event in managing versioning of the set of objects.

Claims

1. A computer implemented method for managing versioning of a set objects in a network data processing system, the computer implemented method comprising:

responsive a first event, sending a first message to a plurality of data processing systems to cause the plurality of data processing system to generate delta data for the set of objects on the plurality of data processing systems in the network data processing system, wherein the delta data is stored for each object in the set of objects to form stored delta data and wherein the stored delta data is subsequently used to return the set of objects to a prior version; and

responsive to a second event, sending a second message to the plurality of data processing systems to cause the plurality of data processing systems to restore the set of objects back to the prior version using the stored delta data, wherein versioning of the set of objects is managed.

2. The computer implemented method of claim 1, wherein the first event is one of an update to the set of objects, an installation of the set of objects on the plurality of data processing systems;

or a request to create a version from an application.

3. The computer implemented method of claim 1, wherein the second event is selected from one of a detection of a virus.

4. The computer implemented method of claim 1, wherein the initiating steps are implemented in a selected data processing system in the network data processing system.

5. The computer implemented method of claim 1, wherein the stored delta data is distributed across the plurality of data processing system in association with the set of objects distributed on the plurality of data processing systems.

6. The computer implemented method of claim 1, wherein the first message is an application programming interface call.

7. The computer implemented method of claim 1 further comprising:

responsive to receiving the first message at a data processing system in the plurality of data processing systems, generating associated delta data for each object located on the data processing system.

8. The computer implemented method of claim 7, wherein the generating step is implemented in a memory management process.

9. The computer implemented method of claim 1, wherein the second event a selected message from a particular object in the set of objects detecting one of a presence of a virus, an error causing an operating system to restart, an application error, or data corruption.

10. The computer implemented method of claim 1, wherein the first message and the second message are sent to the plurality of data processing systems using a multicast process.

11. A network data processing system comprising:

a communications fabric;

a central data processing system connected to the communications fabric;

a plurality of data processing systems connected to the communications fabric;

a set of objects located on data processing systems within the plurality of data processing systems;

wherein the central data processing system sends a first message to the plurality of data processing systems to cause the plurality of data processing systems to generate delta data for the set of objects on the plurality of data processing systems, store the delta data for each object in the set of objects to form stored delta data; and

wherein the central data processing system sends a second message to the plurality of data processing systems to cause the plurality of data processing systems to restore the set of objects back to the prior version using the stored delta data.

12. A computer program product comprising:

a computer usable medium having computer usable program code for implementing a method for managing versioning of a set objects in a network data processing system, said computer program product including;

a computer usable program code, responsive to a first event, for sending a first message to a plurality of data processing systems to cause the plurality of data processing systems to generate delta data for the set of objects on the plurality of data processing systems in the network data processing system, wherein the delta data is stored for each object in the set of objects to form stored delta data and wherein the stored delta data is subsequently used to return the set of objects to a prior version; and

a computer usable program code, responsive to a second event, for sending a second message to the plurality of data processing systems to cause the plurality of data processing systems to restore the set of objects back to the prior version using the stored delta data, wherein versioning of the set of objects is managed.

13. The computer program product of claim 12, wherein the first event is one of an update to the set of objects, an installation of the set of objects on the plurality of data processing systems;

or a request to create a version from an application.

14. The computer program product of claim 12, wherein the second event is selected from one of a detection of a virus.

15. The computer program product of claim 12, wherein the computer usable program code, responsive to a first event, for initiating sending a message to a plurality of data processing systems to cause the plurality of data processing system to generate delta data for the set of objects on the plurality of data processing systems in the network data processing system, wherein the delta data is stored for each object in the set of objects to form stored delta data and wherein the stored delta data is subsequently used to return the set of objects to a prior version are implemented in a selected data processing system in the network data processing system.

16. The computer program product of claim 12, wherein the stored delta data is distributed across the plurality of data processing systems in association with the set of objects distributed on the plurality of data processing systems.

17. The computer program product of claim 12, wherein the first message is an application programming interface call.

18. The computer program product of claim 12 further comprising:

a computer usable program code, responsive to receiving the first message at a data processing system in the plurality of data processing systems, for generating associated delta data for each object located on the data processing system.

19. The computer program product of claim 18, wherein the computer usable program code, responsive to receiving the first message at a data processing system in the plurality of data processing systems, for generating associated delta data for each object located on the data processing system, is implemented in a memory management process.

20. The computer program product of claim 12, wherein the second event is a selected message from a particular object in the set of objects detecting a presence of a virus.
