Abstract

A method includes, in a grid network, querying a grid manager for assignment of a resource for execution of an application, the query including a grid application recovery request, assigning a resource having a grid application recovery service in response to the grid application recovery request, establishing a communication channel between the assigned resource and a recovery application on a recovery resource, and storing recovery information over the communication channel on the recovery resource during execution of the application.

Claims

1. A method comprising:

in a grid network, querying a grid manager for assignment of a resource for execution of an application, the query including a grid application recovery request;

assigning a resource having a grid application recovery service in response to the grid application recovery request;

establishing a communication channel between the assigned resource and a recovery application on a recovery resource;

storing recovery information over the communication channel on the recovery resource during execution of the application.

2. The method of claim 1 wherein the grid application recovery request is an extended markup language (XML) file describing which parts of the application are to be saved during execution, how often the parts are to be saved, and a description of the communication channel.

3. The method of claim 2 wherein establishing comprises passing the XML file to the recovery application on the recovery resource.

4. The method of claim 3 wherein storing comprises:

interrupting the execution of the application in accordance with instructions contained in the XML file;

saving the parts of the executing application by the recovery application on the recovery resource as indicated by the instructions in the XML file; and

resuming the execution of the application.

5. The method of claim 1 further comprising restoring parameters stored in the recovery information to the application in the event of a premature termination of the execution of the application.

6. The method of claim 5 further comprising restarting the execution of the application.

7. The method of claim 1 wherein the grid application recovery service is a web service executing inside a grid container on the recovery resource.

8. A computer program product, tangibly embodied in an information carrier, for application recovery in a grid network, the computer program product being operable to cause data processing apparatus to:

query a grid manager for assignment of a resource for execution of an application, the query including a grid application recovery request;

assign a resource having a grid application recovery service in response to the grid application recovery request;

establish a communication channel between the assigned resource and a recovery application on a recovery resource;

store recovery information over the communication channel on the recovery resource during execution of the application.

9. The product of claim 8 wherein the grid application recovery request is an extended markup language (XML) file describing which parts of the application are to be saved during execution, how often the parts are to be saved, and a description of the communication channel.

10. The product of claim 9 wherein establishing comprises passing the XML file to the recovery application on the recovery resource.

11. The product of claim 10 wherein storing comprises:

interrupting the execution of the application in accordance with instructions in the XML file;

saving the parts of the executing application by the recovery application on the recovery resource as indicated by the instructions in the XML file;

and

resuming the execution of the application.

12. The product of claim 8 further comprising instructions to restore parameters stored in the recovery information to the application in the event of a premature termination of the execution of the application.

13. The product of claim 12 further comprising instructions to restart the execution of the application.

14. The product of claim 8 wherein the grid application recovery service is a web service executing inside a grid container on the recovery resource.

15. A system in a grid compute network comprising:

means for querying a grid manager for assignment of a resource for execution of an application, the query including a grid application recovery request;

means for assigning a resource having a grid application recovery service in response to the grid application recovery request;

means for establishing a communication channel between the assigned resource and a recovery application on a recovery resource;

means for storing recovery information over the communication channel on the recovery resource during execution of the application.

16. The system of claim 15 wherein the grid application recovery request is an extended markup language (XML) file describing which parts of the application are to be saved during execution, how often the parts are to be saved, and a description of the communication channel.

17. The system of claim 16 wherein the means for establishing comprises passing the XML file to the recovery application on the recovery resource.

18. The system of claim 17 wherein the means for storing comprises:

interrupting the execution of the application in accordance with instructions in the XML file;

saving the parts of the executing application by the recovery application on the recovery resource as indicated by the instructions in the XML file; and

resuming the execution of the application.

19. The system of claim 15 further comprising means for restoring parameters stored in the recovery information to the application in the event of a premature termination of the execution of the application.

20. The system of claim 19 further comprising means for restarting the execution of the application.

21. The system of claim 15 wherein the grid application recovery service is a web service executing inside a grid container on the recovery resource.
