Abstract

PURPOSE:To rapidly clear up an unauthorized cause in debugging by constituting a system so that the history of file access performed by a program can be extracted in a program debug support processing. CONSTITUTION:An input/output control part E which controls the file access of an external memory device 3 by each of programs 2-1 to 2-M is instructed to perform an operation to extract the history from a history extraction operation indication part C. Thereby, when the file access for a data set represented by either the data sets registered on a history extraction data indication table holding part A is generated, a program name performing the file access and the content of a targeted data set are sent to and preserved at a history output file D.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program debugging support processing method, and more particularly to a program debugging support processing method that collects history at the time of file access using a debugging tool for program development.

[Conventional technology]

The conventional program debugging support processing method that collects the history of file accesses using a debugging tool for program development is to run a single program, and when that program accesses a file, the history output file shows the history of the file access. The contents of the dataset are saved as a history.

(Problem to be Solved by the Invention) The conventional program debugging support processing method described above can collect historical information about the single operation of program-book-book, but when multiple programs are running, However, the disadvantage is that it is not possible to collect the history of file accesses made by each program.

An object of the present invention is to, when multiple programs operate,
The object of the present invention is to provide a program debugging support processing method that can collect the history of file accesses performed by each program.

[Means to solve the problem]

The program debugging support processing method of the present invention is provided in a computer system having an external storage device and performing processing from at least one program using the external storage device, comprising: N11j that collects history when accessing files in the dataset
(B) A history collection data instruction table management unit that inputs in advance the name of the data set for which ff history collection is to be performed and registers it in the history collection data instruction table storage unit. , (C) a history collection operation instruction unit that instructs operations such as starting and stopping for history collection; (D) the name of the program that executed the file access and the contents of the target Data Sera 1 to 1 in the file access; (E) A history output file to be saved as a history; (E) controlling file access of the external storage device by each of the programs, and instructing the history collection data by receiving a history collection operation instruction from the history collection operation instruction unit; When a file access occurs to a dataset indicated by any of the dataset names registered in the table holding unit, the name of the program that accessed the file and the contents of the target dataset in that file access are written to the history output file. It consists of an input/output control section that sends and stores data.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the program debugging support processing method of the present invention.

As shown in FIG. 1, a central processing unit 1 of a computer system has a plurality of programs 2-1.・・・・・・
. . . From 2-M, file access processing is performed using the connected external storage device 3.

The history collection data instruction table holding unit A stores datasets 1.・・・・・・・・・・・・
...N data set names 1, 2, .・・・・・・N
is held.

The history collection data instruction table management unit B also stores the data set names 1, 2, . . . . Upon receiving N, they can be registered in the history collection data instruction table holding unit A.

On the other hand, the history collection operation instruction unit C is configured by the user to
In response to instructions input from the input/output control unit E, the input/output control unit E is instructed to perform operations such as starting and stopping the history collection.

Further, the history output file D can store the name of the program that executed the file access and the contents of the target data set in the file access as a history.

Therefore, program 2-1.・・・・・・・・・2-M
The input/output control unit E that controls file access to the external storage device 3 by each of the history collection operation instruction unit C
When a file access to a dataset indicated by any of the dataset names registered in the history collection data instruction table holding unit A occurs due to an instruction to perform history collection from , the name of the program that accessed the file. Then, the contents of the target data set in the file access are sent to the history output file D and stored therein.

As described above, the program debugging support processing method of this embodiment can collect the history of file accesses performed by each program when a plurality of programs are running.

In addition, by registering multiple related datasets in the history collection data instruction table and operating them, you can obtain a history of the contents of multiple related datasets.This data can be used to clarify the cause of irregularities during program debugging. can make a significant contribution.

〔Effect of the invention〕

As described above, the program debugging support processing method of the present invention has the advantage that when a plurality of programs are running, it is possible to collect the history of file accesses performed by each program.

In addition, in comprehensive test I in system development, a large number of programs are executed, and if an error occurs in a certain data set due to the execution of these programs, the name of the program that accessed the data set and the data set Since it is possible to examine the contents and history of the program, it is possible to identify or estimate the program that updated the invalid value and its phase, thereby significantly reducing the time required to uncover the cause of the violation. effective.
