Abstract

PURPOSE:To automatically set a work file size to an optimal value, and to prevent the generation of a file over at the time of operating a device. CONSTITUTION:A work file size calculating means 30 reads the content of a work file defining master 40, controls a work information retrieving means 20 to retrieve a pertinent file from a storage means 10 in which a file group is stored based on the content, and searches the present real capacity. This searched present real capacity is multiplied by a free factor included in the read content in order to search the work file size, and the work file size is written in a work file size calculation list 50.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION The present invention is applied to a work file size setting device for an electronic computer device. The present invention relates to a work file size setting device for utility program operation management means.

0002

BACKGROUND OF THE INVENTION Conventionally, there has been no device for calculating the size of a work file, and an administrator of a computer system determines the size of a work file based on experience.

0003

However, as in the past, the decision was made by the computer system administrator based on experience, and there was a problem in that the file size could be incorrectly determined and the program could end abnormally due to overflow or the like.

[0004] The present invention solves the above problems.
The work file size can be automatically set to the optimal value,
Another object of the present invention is to provide a work file size setting device that can prevent file overs from occurring during device operation.

[0005]

[Means for Solving the Problems] The present invention provides a storage means in which a group of files is stored, a file information search means for searching information on the group of files stored in the storage means, and a work file that defines a work file. Based on the definition master, a work file size calculation list that stores the work file size, and the contents of this work file definition master, the file information search means is controlled to search for information on the corresponding file, and the file information is searched based on the search results. The present invention is characterized by comprising a work file size calculation means for calculating the work file size of the corresponding file and writing the calculation result in the work file size calculation list.

Further, in the present invention, the work file definition master may include a work file name, a file name of a file stored in the storage means, and a work file size margin factor.

Further, in the present invention, the work file size calculation list may include a work file name and a size of the work file.

[0008]

[Operation] A work file definition master that defines a work file and a work file size calculation list that stores the work file size are provided. The work file size calculation means controls the file information search means based on the contents of the work file definition master to search the information of the corresponding file from the storage means in which the file group is stored, and based on the search result, searches for the information of the corresponding file. Calculate the work file size of and write the calculation result to the work file size calculation list.

As described above, the work file size can be automatically set to an optimal value, and file overflow can be prevented from occurring during device operation.

Embodiments Examples of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a work file size setting device according to an embodiment of the present invention. In FIG. 1, the work file size setting device includes a storage means 10 in which a file group is stored, a file information search means 20 that searches for information on the file group stored in the storage means 10, and a work file that defines a work file. Controls the file information search means 20 to search for information on the corresponding file based on the contents of the definition master 40, the work file size calculation list 50 that stores the work file size, and the work file definition master 40, and based on the search results. The work file size calculation means 30 calculates the work file size of the corresponding file and writes the calculation result in the work file size calculation list 50.

[0011] Further, the work file definition master 40 is
It includes the work file name, the file name of the file stored in the storage means 10, and the margin factor of the work file size.

Further, the work file size calculation list 50 includes a work file name and a size of the work file.

The operation of the work file size setting device having such a configuration will be explained. FIG. 2 is a flowchart showing the processing of the work file size calculation means of the work file size setting device of the present invention.

In FIGS. 1 and 2, the work file size calculation means 30 first sequentially reads out the contents of the work file definition master 40 (S1). When calculating the size of the work file described in the contents, check which file the size of the work file depends on and check the current capacity of the file (number of records existing in the storage means 10 x Find the size of one record). For this purpose, the file information search means 20 is used to search for information on the corresponding file stored in the storage means 10. (File information search means is provided as standard in ordinary computer equipment.)

Based on the retrieved file information, the number of records existing in the file and the size of one record are determined, and the current actual capacity of the file is determined (S2).

The current actual capacity of the file is multiplied by a margin factor to obtain the work file size (S3).

The obtained work file size is written into the work file size calculation list (S4).

[0018]

As described above, the present invention has the excellent effect of automatically setting the work file size to an optimal value and preventing the occurrence of file over during device operation.
