Abstract

PURPOSE:To reexecute a job from a job starting point and a job step starting point by storing the contents of a file at the job starting point and the job step starting point excluding its leading point. CONSTITUTION:Prior to the execution of file open processing by a file processing part 1, a file fault processing control part 2 receives the order of a current job step in the execution of the job from a job step order deciding part 3. When the current job step is the leading job step, the control part 2 reads out the contents of a leading job step file storing part 4 and writes the contents in a file storing part 6. Consequently, the contents of the file are restored at the leading job step. When the current job step is other than the leading job step, the control part 2 reads out the contents of a file storing part 5 for job steps other than the leading job step and writes the contents in the file storing part 6 to restore the contents of the file at the leading job step.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a file failure handling method in an information processing device, and in particular, when a job consisting of multiple job steps terminates abnormally, It concerns a method that can be re-executed on both sides.

(Prior art) Conventionally, this type of file failure handling method stores file update page information after an arbitrary point in time during job execution, thereby making it possible to always re-execute from that point. It was structured as follows.

(Problem to be Solved by the Invention) The conventional file failure handling method described above is a method configured to allow re-execution from any point that can be set arbitrarily, but only one re-execution point can be set at a time. So,
This method has the disadvantage that it cannot handle cases where there is a possibility of re-execution from the start point of a job step and re-execution from the start point of the job.

An object of the present invention is to eliminate the above-mentioned drawbacks by storing the contents of the file at the time of starting a job and the contents of the file at the time of starting a job step other than the beginning, and to provide a structure that can satisfactorily execute file failure processing. The purpose of this invention is to provide a method for handling file failures.

(Means for Solving the Problems) The file failure handling method according to the present invention includes a file processing unit, a job step order determination unit, a file failure processing management unit, a file content storage unit for the first job step, and a first job step processing unit. It is configured to include a file content storage section for use other than steps and a file storage section.

The file processing unit is for executing file processing.

The job step order determination unit is for determining the current job step order during job execution.

The file failure processing management unit receives the current job step order from the job step order determination unit and manages files in response to file failures.

The first job step file content storage section is for providing the first job step file to the file failure processing management section at the time of job start. .

The file content storage unit for files other than the first job step is for providing files for other than the first job steps to the file failure processing management unit at the time of job start.

The file storage section is for storing a file for the first job step or a file for a job other than the first job step in response to a request from the file failure processing management section.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a file failure handling method according to the present invention. In FIG. 1, 1 is a file processing unit, 2 is a file failure processing management unit, 3 is a job step order determination unit, 4 is a file content storage unit for the first job step, 5 is a file content storage unit for other than the first job step, 6 is a file storage section.

In FIG. 1, the file processing section 1 includes a data transfer path 11
File processing is performed on the file storage section 6 via. Before executing the file oven process, the file processing unit 1 notifies the file failure process management unit 2 via the data transfer path 13 that the above process is necessary. The file failure processing management unit 2 receives the current job step order during job execution from the job step order determination unit 3 via the data transfer path 7. If the current job step is the first job step, if the data is saved in the first job step file storage section 4, the job will be re-executed from the beginning after the abnormal termination. Therefore, the inside of the first job step file storage section 4 is read out via the data transfer path 8 and written into the file storage section 6 via the data transfer path 10.

This restores the file contents to the beginning of the job. If no data is stored in the file storage unit 4 for the first job step, the contents of the file are read from the file storage unit 6 via the data transfer path 10 and are stored in the file storage unit 4 for the first job step via the data transfer path 8. Write the above contents to .

If the current job step is other than the first job step and data is stored in the non-first job step file storage unit 5, re-execution will be started from the beginning of the job step after the abnormal termination. Therefore, in this case, by reading the contents of the file storage section 5 for use other than the first job step via the data transfer path 9 and writing them to the file storage section 6 via the data transfer path 10, The contents of the file are recovered at the point in time. If data is not stored in the file storage unit 5 for use other than the first job step, the data is stored in the file storage unit 6 via the data transfer path 10.
The contents of the file are read from the file storage section 5 for files other than the first job step via the data transfer path 9? It's crowded.

After executing file close processing, the file processing section 1 notifies the file failure processing management section 2 of the execution of the above processing via the data transfer path 12. The file failure processing management unit 2 receives the current job step order during job execution from the job step order determination unit 3 via the data transfer path 7 . Currently, if it is the final job step, the contents of the file storage section 4 for the first job step are erased via the data transfer path 8, and the contents of the file storage section 5 for other than the first job step are erased via the data transfer path 9. to erase. If the current job step is other than the final job step, the contents of the file storage section 5 for other than the first job step are erased via the data transfer path 9.

(Effects of the Invention) As explained above, the present invention enables re-execution from the start of a job by storing the contents of a file at the start of a job and the contents of a file at the start of a job step other than the beginning. , and re-execution from the start point of the job step.
