Abstract

PURPOSE:To attain accurate correction history control by controlling correction history information in the same file as a control program (operating system (OS) program) constituting the OS. CONSTITUTION:In the case of correcting the OS program in accordance with correction instruction data 11 instructed by a correcting article through a correcting means 2, the correcting means 2 informs a corrected result to a correction history control means 3 and instructs the recording of the history information 12 of the correcting article 1 described in the article 1 in a correction history control table 62. The means 3 records the execution date of correction and the history information 12 of the correcting article 1 in the table 62 together with the corrected result. Thereby, information relation to the correction history of the OS program is automatically recorded simultaneously with the correction of the OS program. Consequently, this history relating to the correction of the OS program is simply and accurately controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for modifying a control program (hereinafter referred to as an OS program) constituting an operating system of a computer.

[Prior art 1] Conventionally, an OS program is modified only by an OS program modification means based on instructions from modification data, and the modification contents and modification date and time are not managed as modification history information. Ta.

For this reason, the history of modifications made to an OS program cannot be referenced from the OS program or the file storing the OS program, and the person implementing the modification uses the form to modify the OS program. Managed history.

Note that the modification history information here refers not only to the content, method, type of modification, and identification name of the modified property written in the modified property, but also to information related to the modification, such as the date and time when the modification was performed, and the results of the modification. This is a general term for information.

[Problems to be Solved by the Invention] Therefore, the modification history information regarding the modification of the OS program must be recorded in a form by the implementer separately from the OS program or the file storing the OS program, which is cumbersome to manage. Furthermore, errors are likely to occur in the management of modifications, such as the information recorded in the form sometimes not matching the actual modification of the OS program.

[Means for Solving the Problems] The operating system modification management method of the present invention has an OS program modification history management table incorporated as OS program data in a file storing the OS program, and The property has history information of the modified property as well as OS program modification instruction data,
a modification means for modifying an OS program based on modification instruction data written in a modification object; a modification history management means for recording the contents of modifications as a history, managing and displaying the same on a display device; and a modification history for the above-mentioned modification history. and OS startup means for starting the OS after separating the management table from the OS program.

[Operation] The present invention automates the management of information regarding the history of OS program modifications, and also incorporates a modification history management table that holds modification history information of the OS program as data in the OS program. By storing the table in a storage file and separating it from the OS program when the OS is actually started, the modification history information can be saved in the same file as the OS program so as not to have any effect on the operation of the OS program. This allows for more accurate revision history management.

〔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 a modification history management method for an operating system according to the present invention.

In this embodiment, an OS program storage file 60 in which an OS program 61 and a modification history management table 62 are stored, modification instruction data 11, and history information 12 of modified objects.
It is composed of a modified object l in which is written, a modification means 2, a modification history management means 3, an OS starting means 4, and a display device 31.

The modification history management table 62 is a table for managing history information of modifications to the OS program 61.
As the data of the OS program 61, ○S program 6
1, the OS program storage file 6
Stored at 0. The modification object 1 includes specific modification instruction data 11 for modifying the OS program 61, as well as history information 12 of the modification object 1, such as the method, cause, and type of modification. The modification means 2 reads modification instruction data 11 of the OS program from the modification object l, and modifies the OS program 6 according to the modification instruction data 11.
This is a means for making the correction in step 1. The modification history management means 3 reads the modification history information 12 from the modification object l, records it in the modification history management table 62 together with the results of the modification carried out by the modification means 2, or displays it on the display device 31. This is a means for displaying recorded correction management information. OS
The program starting means 4 is a means for reading the OS program 61 from the OS program storage file 60, expanding it into the main memory or virtual memory of the computer, and starting the execution of the OS. The activated OS program 5 is shown conceptually in this figure, and can be considered as an OS program deployed in main memory or virtual memory in order to actually operate as an OS.

Next, the operation of this embodiment will be explained.

When modifying the OS program, the modifying means 2 modifies the OS program 61 according to the modification instruction data 11 instructed by the modification object l. In addition to notifying the result of the correction process, the history information 12 of the corrected property 1 described in the corrected property 1 is transmitted to the correction history management table 6.
Instruct to record in 2.

Upon receiving the instruction, the modification history management means 3 records the result of the modification process received from the modification means 2, as well as the date and time of the modification.
The history information 12 of the modified property read from the modified property 1 is recorded in the modification history management table 62.

The OS program 61 that has been modified in this way includes a modification history management table 62 as data, but when the OS startup means 4 starts the OS program, the modification history management table 62 that is not related to the operation of the OS is used. Since the table 62 is excluded and only the OS program 61 is developed in the main memory or virtual memory and the execution of the OS program 61 is started, there is no problem during the execution of the OS program 61.

Furthermore, apart from the execution of modifications, the modification history management means 3 can use the display device 31 to refer to modification history information recorded in the modification history management table 62 at any time. .

[Effects of the Invention] As explained above, the present invention includes a modification history management table that holds modification history information of the OS program in the storage file of the ○S program in a form that is incorporated as data of the ○S program. By separating this table from the OS program when the OS program is actually started, information regarding the history of modifications to the OS program can be recorded simultaneously and automatically. It is now possible to maintain correct and complete information, and since the modification history information can be handled in the same way as the OS program without causing any hindrance to the operation of the OS program, it is possible to prevent modification history information from being lost. In addition, the recorded modification history information can be easily referenced from the OS program storage file, which simplifies and simplifies the management of the history of OS program modifications. This has the effect of making it possible to perform the process accurately.
