Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a file processing method and a storage medium for performing business processing on a computer, for example.
[0002]
[Prior art]
For example, in order to operate software developed in a business processing language such as COBOL under the environment of a predetermined operating system (hereinafter referred to as OS), the file extension mechanism largely depends on the OS.
[0003]
For example, under the OS environment of TP, when creating a file with COBOL software, the OS automatically increases the disk free space from the smallest one to the maximum even if the number of file expansions is specified large. You can only get up to 32 times.
[0004]
[Problems to be solved by the invention]
In the case of such a file extension method, the requested number of files cannot be secured sufficiently, and if the number of files output in each job or step is larger than the preset number of files, there is a problem of causing a file overflow. there were.
[0005]
When a file overflow occurs, an operator will perform a recovery operation, and this recovery operation often involves an operation error.
[0006]
The present invention has been made to solve such a problem, and an object of the present invention is to provide a file processing apparatus that can eliminate a file overflow occurring during processing as much as possible.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the file processing method according to claim 1 is a file processing method for processing a file by executing a plurality of jobs, wherein the number of output files is larger than a preset initial number of files. When the file size increases, the automatic file extension processing unit of the computer sets the first job name, step name, file name, file organization, record length, block length, initial file number, allocation number, ratio, and flag using the first job as a key. There are setting items to be included, of which the file name is extracted from the file information table in which initial values are set for the first job name, the step name, the file name, and the initial number of files, and an extension target file is selected. and the output data count × ratio allocation number for each file name extracted And setting a value, in order to perform the file extension for all files that are selected to augment, the automatic file extension processing section deletes the file, file organization, a record length of the file information table, block length, After allocating based on the number of allocations, newly creating each file to be expanded, and after successfully completing the processing, the automatic file extension processing unit has already expanded the flag on the file information table . The file extension process is completed, and the daily processing unit of the computer that has been started up after the end of the work deletes the file for the file whose flag has already been extended, and stores the file on the file information table. Perform allocation based on the initial number of files of Returning to the initial number of files.
[0009]
The storage medium according to the second aspect of the present invention is the storage medium storing a program for causing a computer that executes a plurality of jobs to perform processing, when the number of output files becomes larger than a preset initial number of files. Using the job as a key, setting items including the first job name, step name, file name, file organization, record length, block length, initial file count, allocation count, ratio, and flag are provided, of which the first job name, the step From the file information table in which the initial value is set for the file name, the file name, and the initial file number, select the file to be expanded by extracting the corresponding file name, and the number of output data in the allocation number for each extracted file name and × setting a value of the ratio, all files that have been selected to augment To perform the file extension with, delete the file, file organization, a record length of the file information table, block length, after allocation based on allocation number, the steps of creating a new respective expansion target file, after successful completion of a process, the file information to set the flag in the table to a file extension already state, the method comprising: ending the file expansion process, after the close of business, the flag files for files in the file extension already state And the computer stores the program so that the computer can perform the process of allocating the file based on the initial number of files on the file information table and returning the expanded file to the initial number of files. It is a feature.
[0011]
In the present invention, the number of files output in the process of the first job or the first step is counted, and when the number of output files is compared with the initial number of files, an overflow is predicted. Because the number of files is automatically expanded to the number that does not overflow based on the parameters (ratio) that have been set, it is possible to prevent file overflow unless an output file that far exceeds expectations is generated. it can.
[0012]
As a result, file overflow that occurs during processing can be minimized. Further, it is possible to eliminate a recovery work by an operator and a work error associated with the work that have been performed when a file overflow has occurred.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing the configuration of a file processing apparatus according to an embodiment of the present invention.
[0014]
As shown in the figure, this file processing device includes disk devices 1a and 1b in which data to be processed is stored, a file information table 2, a file automatic extension processing unit 3, and files to be extended 11, 12, 13, and 14. Etc.
[0015]
The files 11, 12, 13, and 14 to be expanded are semi-organized files that are used for work in processing for each job or step, and are not master files.
[0016]
Here, the file information table 2 will be described with reference to FIGS.
As shown in FIG. 2, the file information table 2 includes record layouts such as the first job name, step name, file name, file organization, record length, block length, initial file number, allocation number, ratio, expansion flag, and spare. It is something to take.
[0017]
Specifically, as shown in FIG. 3, the file information table 2 includes, for example, job 1 as the first job name, job 1 as the job name, step 1 as the step name, A as the file name, and the initial number of files. 1000 or the like is set as an initial value.
[0018]
The operation of this file processing apparatus will be described below with reference to FIGS.
In the case of this file processing apparatus, in the process of step 1 of job 1, that is, the processing of the startup job, when the data is read from the disk device 1a or the disk device 1b, the data processing is executed, and the file is output, the startup job Counts the number of data (S101), and passes the own job name, own step name, output file name, and number of output data items to the automatic file extension processing unit 3.
[0019]
When the output data is transferred from the startup job, the automatic file extension processing unit 3 recognizes the startup job (S102), refers to the file information table 2 based on the number of output data, the first job name, the step name, and the file name. The actual number of output data of the corresponding file name is compared with the preset initial number of files to determine whether the output file is full (S103).
[0020]
For example, if the actual number of output files is 2000, the number of output files is larger than the initial number of files because the initial number of files is 1000. In this case, the file overflows.
[0021]
In such a case, since it is necessary to expand all files on the job net, the automatic file extension processing unit 3 extracts the corresponding file name from the file information table 2 using the first job as a key, A file is selected (S104), and as shown in FIG. 5, the number of output data times the ratio is set as the number of allocations for each file name. That is, a file whose first job is “Job 1” is extracted, and the value of output data number × ratio is set as the number of allocation of each file A to M in the file information table 2.
[0022]
When the number of output files of file A is 2000 as in this example, the ratio of this file A is set to 1, and the allocation number is set by multiplying 2000 by the ratio of other files B to M.
[0023]
Then, the file automatic extension processing unit 3 deletes the files to perform file extension for all files (S105), and performs allocation based on the file organization, record length, block length, and number of allocations in the file information table 2. Thereafter, a new target file is created (S106).
[0024]
Then, after completing the processing normally, the automatic file extension processing unit 3 sets the flag on the file information table 2 to “1” (S107), and ends the file extension processing (S108).
[0025]
When the daily processing is started at night after the work is finished, the started daily processing deletes the file with the extension flag “1” and performs allocation based on the number of files on the file information table 2. The expanded file is returned to the initial number of files (S109).
[0026]
As described above, according to the file processing apparatus of this embodiment, by referring to the file information table 2 and allocating files based on the number of data output, the file capacity is not allocated at a fixed (maximum value), and the disk is not used. The area can be eliminated and resources can be used effectively.
[0027]
Further, it is possible to eliminate the recovery work by the operator and the work mistakes associated with the work, which have been conventionally performed due to the occurrence of the file overflow.
[0028]
Furthermore, by using the file information table 2, file allocation can be easily performed when creating a system environment.
[0029]
In addition, this invention is not limited only to the said embodiment.
In the above embodiment, the file automatic extension processing unit 3 is provided for one job and the file is automatically extended for each step. However, for example, as shown in FIG. When the first to fourth jobs 1 to 4 are connected (referred to as a job net), a file automatic extension processing unit 63 that monitors all the jobs 1 to 4 and automatically extends the files 13 to 16 is provided. All other files 13 to 16 may be automatically expanded.
[0030]
Further, the automatic file extension processing units 3 and 63 in the above embodiment can be realized by software or hardware. When the automatic file extension processing units 3 and 63 are realized by software, they may be stored in a computer-readable storage medium such as a floppy disk. In this case, the computer reads out the software stored in the storage medium. The processing in each embodiment becomes possible. The automatic file extension processing unit 3 realized by software may be incorporated as a module of a part of software that executes one job, and the automatic file extension processing unit 63 is software different from software that executes a job net. Also good.
[0031]
As storage media, programs such as magnetic disk, floppy disk, hard disk, optical disk (CD-ROM, CD-R, DVD, etc.), magneto-optical disk (MO, etc.), semiconductor memory, etc. can be stored and read by a computer. As long as it is a possible storage medium, the storage format may be any form.
[0032]
Further, based on an instruction of a program installed in a computer from a storage medium, an OS (operating system) running on the computer, database management software, MW (middleware) such as network software, and the like realize this embodiment. A part of each process may be executed.
[0033]
Furthermore, the storage medium is not limited to a medium independent of the computer, but also includes a storage medium in which a program transmitted via a LAN or the Internet is downloaded and stored or temporarily stored.
[0034]
Further, the number of storage media is not limited to one, and the case where the processing in the present embodiment is executed from a plurality of media is also included in the recording medium in the present invention, and the media configuration may be any configuration.
[0035]
The computer executes each process in the present embodiment based on a program stored in a storage medium, and includes any one device such as a personal computer or a system in which a plurality of devices are connected to a network. It may be configured as follows.
[0036]
The computer is not limited to a personal computer, but includes an arithmetic processing device, a microcomputer, and the like included in an information processing device, and is a generic term for devices and devices that can realize the functions of the present invention by a program.
[0037]
【The invention's effect】
As described above, according to the present invention, it is possible to overflow by counting the number of files output in the process of the first job or the first step and comparing the number of output files with the initial number of files. When predicted, since the number of all files is automatically expanded to a number that does not overflow based on a preset parameter (ratio), file overflow that occurs during processing can be minimized.
