Abstract

PURPOSE:To improve the reliability of data processing by constituting a storage device of plural pieces of volumes, and also subdividing the volume so as to be designated by a table for showing assigned data of each page. CONSTITUTION:A storage device is constituted of plural volumes 1-3, and in each volume, data for laying out space ranging through plural pages is stored so as to correspond to each page. In that case, each volume is further divided into blocks 11, 12... and assigned data of each page is stored, and also its assignment is shown clearly in a table. This assignment is executed so that a busy column is stored in a different volume as equally as possible. Also, when data of a desired quantity is extracted from each volume at a desired time point and space is manufactured in the lump, maintenance of the data is executed at every prepared column (page), by which it does not occur that the whole system for preparing a newspaper becomes down. In this way, the reliability of a data processing can be improved.

Description

[Detailed Description of the Invention] [1] Regarding the storage device of an information processing system that stores data for producing newspaper pages, the storage device is configured with a plurality of volumes, and the division is specified using a table. The volume is further subdivided to improve the reliability of data processing.

[Industrial Application Field] The present invention relates to a storage device for an information processing system, which is a storage device composed of a plurality of volumes, and which is capable of efficiently allocating storage by dividing one volume into smaller pieces. Regarding the method.

[Prior Art] When creating a newspaper page, a large amount of data is stored in a storage device and then edited and corrected repeatedly using a computer. At this time, a plurality of large-capacity storage devices called direct access storage devices (DASD) are used as storage devices. Each DASD is called a volume. For example, in a newspaper, like an article on social issues,
A logical chunk of data from the user's (newspaper producer's) perspective does not always exist in a single volume;
In many cases, there are differences in the arrival time of articles and the amount of articles, so
Data will be scattered across multiple volumes. The user extracts a desired amount of data from each storage device at a desired time and collectively creates a newspaper page.

[Problems to be Solved by the Invention] If a mechanical failure occurs in any volume, paper production will stop. Additionally, there are temporal variations in the way articles are collected, creating time periods that place a heavy load on computers. And it is extremely difficult to distribute the load using current methods.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for storing data in a storage device that improves the reliability of data in the storage device and makes it possible to distribute the load in order to improve the above-mentioned problems.

[Means for Solving the Problems] The means adopted by the present invention to achieve the above-mentioned object is to store data for paper production over a plurality of pages in a plurality of different storage devices, and to store data for each storage device at a desired time. In the above-mentioned storage device allocation method for an information processing system in which a desired amount of data is extracted from and collectively produced, the storage device is composed of a plurality of volumes, each volume stores data corresponding to each page, and The present invention is to provide a table showing allocation data for each page in which a volume is divided and stored.

[Function] Like a newspaper, the paper surface (page) and volume
Data is allocated and stored in association with each other. Therefore, once stored, if corrections or additions are to be made, the target volume can be found by correlating the contents of the table with the data.

[Example] Figure 1 is a diagram showing the configuration of an example of the present invention when it is used for creating newspaper pages. Figure 1A shows the volume, and Figure 1B shows an example of a table. .

In Figure 1A, 1.2.3 is the first volume, the second volume,...1
1.21.・・・・・・〜 is 1 section of the 1st volume, 2
Section - 2L, 22. - indicates the 1st section and 2nd section of the second volume.

Further, in FIG. 1B, 4 indicates the entire table. In FIG. 1, allocation of each volume is performed as shown in FIG. 2. In other words, when we take the "-" side of the newspaper production side (for example, the political article side), the "social side" on the vertical axis, and the time on the horizontal axis, and then update the edition number for each page, the horizontal lines converge. Indicates that you are busy because the time is at work.

For example, from 12:00 until the first hour in the afternoon, I am often busy editing the evening edition.

Therefore, in the table shown in FIG. 1B, the busy areas are allocated to different volumes so that they are stored as evenly as possible. Therefore, when the "- side" is updated as in the 7th to 9th editions, it does not affect the storage and updating of the "radio/television side".

In terms of production operations, it is best to protect the data for each production page (page) to prevent the entire newspaper production system from going down. For example, if you prepare one free DASD,
[This is because it is sufficient to perform data transfer when 8 occurs.

Also, when the title, article text, and explanation are all combined into one, such as a large article, in order to finish editing,
Although it is necessary to perform exclusive processing and check the completion of each part sequentially, in this invention, it is not necessary to perform exclusive processing for other volumes, and it is also necessary to perform exclusive processing for other partitions within the same volume. There is no.

The present invention is not limited to the production of newspaper pages, but can be applied to processing a large amount of data on different pages.

[Effects of the Invention] In this way, according to the present invention, data that comes in at different densities in time are stored in different storage devices during the same time period, and the allocation is clearly defined in the table, so that problems can be avoided. without system down.
Improved reliability of data processing. Furthermore, the operational load on the central processing unit can be greatly reduced by storing data appropriately.
