Abstract

A trace file collection system for implementing a trace file collection method for a soft error collection of one or more trace files associated with a data processing device. The method involves a periodic retrieval of an error log from the data processing device, a comparison of two or more retrieved error logs, and a retrieval of the trace file(s) from the data processing device based on the comparison of the two or more retrieved error logs indicating an occurrence of one or more soft errors within the data processing device.

Claims

1. A computer bearing medium tangibly embodying a program of machine-readable instructions executable by a processor to perform operations for a soft error collection of at least one trace file associated with a data processing device, the operations comprising:

periodically retrieving an error log from the data processing device;

comparing at least two retrieved error logs; and

retrieving the at least one trace file from the data processing device based on the comparison of the at least two retrieved error logs indicating an occurrence of at least one soft error within the data processing device.

2. The computer bearing medium of claim 1, wherein the data processing device is an automated tape library.

3. The computer bearing medium of claim 1, wherein the operations further comprise:

storing each retrieved error log within an error log table.

4. The computer bearing medium of claim 1, wherein the comparing of at least two retrieved error logs includes:

identifying each software error entry of a currently retrieved error log absent from a previously retrieved error log.

5. The computer bearing medium of claim 4, wherein the comparing of at least two retrieved error logs further includes:

applying a filter to each identified software error entry.

6. The computer bearing medium of claim 5, wherein a trace file is retrieved in response to at least one identified software error entry passing through the filter.

7. The computer bearing medium of claim 1, wherein the operations further comprise:

storing each retrieved trace file in a unique file directory.

8. A trace file collection system, comprising:

a processor; and

a memory storing instructions operable with the processor for a soft error collection of at least one trace file associated with a data processing device, the instructions are executed for;

periodically retrieving an error log from the data processing device;

comparing at least two retrieved error logs; and

retrieving the at least one trace file from the data processing device based on the comparison of the at least two retrieved error logs indicating an occurrence of at least one soft error within the data processing device.

9. The trace file collection system of claim 8, wherein the data processing device is an automated tape library.

10. The trace file collection system of claim 8, wherein the instructions are further executed for:

storing each retrieved error log within an error log table.

11. The trace file collection system of claim 8, wherein the comparing of the at least two retrieved error logs includes:

identifying each software error entry of a currently retrieved error log absent from a previously retrieved error log.

12. The trace file collection system of claim 11, wherein the comparing of the at least two retrieved error logs further includes:

applying a filter to each identified software error entry.

13. The trace file collection system of claim 12, wherein a trace file is retrieved in response to at least one identified software error entry passing through the filter.

14. The trace file collection system of claim 8, wherein the instructions are further executed for:

storing each retrieved trace file in a unique file directory.

15. A trace file collection method for a soft error collection of at least one trace file associated with a data processing device, the method comprising:

periodically retrieving an error log from the data processing device;

comparing at least two retrieved error logs; and

retrieving the at least one trace file from the data processing device based on the comparison of the at least two retrieved error logs indicating an occurrence of at least one soft error within the data processing device.

16. The trace file collection method of claim 15, wherein the data processing device is an automated tape library.

17. The trace file collection method of claim 15, further comprising:

storing each retrieved error log within an error log table.

18. The trace file collection method of claim 15, wherein the comparing of the at least two retrieved error logs includes:

identifying each software error entry of a currently retrieved error log absent from a previously retrieved error log.

19. The trace file collection method of claim 18, wherein the comparing of the at least two retrieved error logs further includes:

applying a filter to each identified software error entry.

20. The trace file collection method of claim 19, wherein a trace file is retrieved in response to at least one identified software error entry passing through the filter.

21. The trace file collection method of claim 15, wherein the instructions are further executed for:

storing each retrieved trace file in a unique file directory.
