Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] This is a control method for efficiently resuming a work requiring a long time processing after interruption. In order to guarantee the target file for long-term processing, in a system that executes processing on a temporary file that is a copy of a real file during processing, at the time of interruption, save this temporary file and the information necessary for restarting,
When restarting, use the temporary file that has been saved so that processing can continue immediately.

[Industrial application field]

The present invention relates to a control method for efficiently resuming a process that requires a long period of time after a process is interrupted.

When designing / changing equipment such as telephone lines and gas pipes using a computer-based design system such as so-called CAD, it often takes several tens of days to design one area.

In such a case, the design process is divided at least every day, and thus it is desired to efficiently control the interruption / restart of the process in terms of work efficiency.

[Problems to be solved by conventional technology and invention]

FIG. 2 is a block diagram of a configuration example of a computer system.

A plurality of terminal devices 1 access the computer 2 and execute business processes of the respective terminal devices. The data required for these processes is stored as a file stored in the storage device 3, which is composed of a magnetic disk storage device or the like.

For example, in a CAD system for constructing a telephone line, each terminal device 1 is designed to share design work for each region, for example, and proceeds with design processing for various files determined by each shared region for several days or more. The required file is updated according to the result.

In that case, the processing target files 4-1 and 4 can be obtained by accessing the computer 2 from the terminal device 1 by a known method, designating and starting an application program determined by design contents, and designating a design area and the like. -2 ... is decided.

Here, in order to prevent the original file to be processed from being updated with inappropriate contents by erroneous processing, that is, to guarantee the file, the file to be processed (this A temporary file 5-1, 5-2, ... which is a copy of 4-1, 4-2, ... and a file correspondence table 6 between the real file and the temporary file is created, -When the processing for 2 ... is executed for the temporary files 5-1, 5-2, ..., When the processing is completed normally, the temporary files 5-1, 5
-2, ..., update corresponding to each real file 4-
It is reflected in 1, 4-2, ....

In such a system, the end of the working day of the day,
Or, for example, when a predetermined command is input in order to interrupt the processing from the terminal device 1 during a break time, the actual files 4-1 and 4-2 are displayed as the processing results up to that point, as when the design processing is completed. Are updated, and the temporary files 5-1, 5-2, ... And the file correspondence table 6 are erased, and then the process is controlled to end.

Therefore, when restarting the interrupted design process on the next day or the like, a copy of the actual files 4-1, 4-2, ... Is again taken by the same procedure as when the first design process was started. After reconstructing the file, it is possible to start the continuous processing such as the previous day.

For this reason, there is a problem that the same complicated procedure and a relatively long processing time for preparation / cleanup are required every time the processing is interrupted / restarted.

[Means for solving problems]

 FIG. 1 is a block diagram showing the configuration of the present invention.

In the figure, reference numeral 10 is process restart control information created corresponding to the terminal device 1 and held in the storage device 3 when the process is interrupted.

[Work]

When the process started by the terminal device 1 is interrupted by an interrupt command or the like from the terminal device 1 as in the conventional case, the management program of the computer 2 causes the file correspondence table 6 used in the process currently being executed. And temporary files 5-1, 5-2, ...
And the control information necessary for restarting the processing by using these temporary files.
After that, the process is terminated as in the conventional method after being stored in the storage device 3.

When a restart request is issued from the same terminal device 1, that terminal device 1
The process can be immediately restarted by the process restart control information 10 corresponding to.

〔Example〕

In FIG. 1, the process restart control information 6 is individually created and stored in the storage device 3 for each terminal device 1 whose processing has been interrupted.

The process restart control information 6 is, for example, the corresponding terminal device name 11,
It consists of a design area name 12, an application program name 13, and a pointer 14 to the file correspondence table 6.

When the terminal device 1 inputs a predetermined command for restarting when restarting the process, the management program of the computer 2 identifies the corresponding process restart control information 10 by the terminal device name of the terminal device 1, and designs it. A designated application program is started by the area name 12 and the application program name 13, and the processing target files are the real files 4-1, 4-2, ... designated by the file correspondence table 6 pointed by the pointer 14, and Temporary files 5-1, 5-2,
Is ...

Therefore, the restart control of the process is performed quickly, and the restart operation required in the terminal device 1 is omitted, and the work efficiency is improved.

〔The invention's effect〕

As is clear from the above description, according to the present invention, the restart control time after interruption in the design process or the like of the computer system, which requires a long time, is shortened and the operation is simplified. There is a significant industrial effect of improving efficiency.
