Abstract

Embodiments of the present invention address deficiencies of the art in respect to fault handling and provide a method, system and computer program product for run-time fault resolution from development time fault and fault resolution path identification. In an embodiment of the invention, a method for run-time fault resolution from development time fault and fault resolution path identification can be provided. The method can include detecting a recoverable fault condition in a computing system, selecting a fault resolution path from amongst a multiple development time specified fault resolution paths to match the recoverable fault condition, prompting an operator with the selected fault resolution path, and resuming operation of the computing system without restart subsequent to the operator performing the selected resolution fault path.

Claims

1. A method for run-time fault resolution from development time fault and fault resolution path identification, the method comprising:

detecting a recoverable fault condition in a computing system;

selecting a fault resolution path from amongst a plurality of development time specified fault resolution paths to match the recoverable fault condition;

prompting an operator with the selected fault resolution path; and

,

resuming operation of the computing system without restart subsequent to the operator performing the selected resolution fault path.

2. The method of claim 1, wherein detecting a recoverable fault condition in a computing system, comprises detecting a low resource condition in the computing system.

3. The method of claim 1, wherein prompting an operator with the selected fault resolution path, comprises prompting an operator to re-prioritize an existing job in the computing system.

4. The method of claim 1, wherein prompting an operator with the selected fault resolution path, comprises prompting an operator to terminate an existing job in the computing system.

5. The method of claim 1, wherein prompting an operator with the selected fault resolution path, comprises prompting an operator to pause operation of the computing system while adding new resources to the computing system.

6. The method of claim 1, wherein prompting an operator with the selected fault resolution path, comprises prompting an operator to pause operation of the computing system while reallocating an existing resource to a different job in the computing system.

7. A computer data processing system configured for run-time fault resolution from development time fault and fault resolution path identification, the system comprising:

a host computing platform supporting an operating system and job controller;

a computer program executing in the operating system, the computer program comprising a plurality of jobs managed by the job controller; and

,

a recoverable fault handler comprising program code enabled to detect a recoverable fault condition in the system, to select a fault resolution path from amongst a plurality of development time specified fault resolution paths to match the recoverable fault condition, to prompt an operator with the selected fault resolution path, and to resume operation of the system without restart subsequent to the operator performing the selected resolution fault path.

8. The system of claim 7, wherein the recoverable fault handler is coupled to the operating system.

9. The system of claim 7, wherein the recoverable fault handler is coupled to the job controller.

10. The system of claim 7, wherein the recoverable fault handler is coupled to the computer program.

11. The system of claim 7, wherein the recoverable fault handler is coupled to at least one of the jobs.

12. A computer program product comprising a computer usable medium embodying computer usable program code for run-time fault resolution from development time fault and fault resolution path identification, the computer program product comprising:

computer usable program code for detecting a recoverable fault condition in a computing system;

computer usable program code for selecting a fault resolution path from amongst a plurality of development time specified fault resolution paths to match the recoverable fault condition;

computer usable program code for prompting an operator with the selected fault resolution path; and

,

computer usable program code for resuming operation of the computing system without restart subsequent to the operator performing the selected resolution fault path.

13. The computer program product of claim 12, wherein the computer usable program code for detecting a recoverable fault condition in a computing system, comprises computer usable program code for detecting a low resource condition in the computing system.

14. The computer program product of claim 12, wherein the computer usable program code for prompting an operator with the selected fault resolution path, comprises computer usable program code for prompting an operator to re-prioritize an existing job in the computing system.

15. The computer program product of claim 12, wherein the computer usable program code for prompting an operator with the selected fault resolution path, comprises computer usable program code for prompting an operator to terminate an existing job in the computing system.

16. The computer program product of claim 12, wherein the computer usable program code for prompting an operator with the selected fault resolution path, comprises computer usable program code for prompting an operator to pause operation of the computing system while adding new resources to the computing system.

17. The computer program product of claim 12, wherein the computer usable program code for prompting an operator with the selected fault resolution path, comprises computer usable program code for prompting an operator to pause operation of the computing system while reallocating an existing resource to a different job in the computing system.
