Abstract

PURPOSE:To start the on-line service to be executed tomorrow as scheduled to execute all the scheduled updating by starting partially the service, and on the other hand, continuing the unfinished updating, even in the case updating after the on-line operation is not finished before the time of starting the on-line next day. CONSTITUTION:The device is constituted of a management table 22 for managing whether the partial service can be executed or not for the purpose of partial use of a data file 21 on a storage device 20, a file managing part 23 for managing a file based on a managed state, a data collecting part 12 for receiving a notice related to whether the service can be started with regard to its file or not from an updating part 11 for updating the data file 21, a management table updating part 13 for updating a management table 22, based on information collected to the data collecting part 12, and a display device 30 for displaying and outputting the degree of the present service. In such a state, updating which is not finished even after an on-line system is started is continued by the file updating part 11. In such a way, it does not occur that the unprocessed part is carried over to the next day.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an online business processing system and means for operating and managing data files on its storage device, and in particular, the present invention relates to a business processing online system and means for operating and managing data files on its storage device. The present invention also relates to an online partial service device for an online office processing system that requires some processing even during daily online operations.

[Conventional technology]

In an online office processing system, tens to thousands of terminal devices are connected to a host computer, and users in various departments refer to and update data files on a storage device through the terminal devices. On the other hand, this data file may be input data from other administrative processing online systems or Table of Contents 9
Weekly September Monthly.

It is updated based on the administrative procedures to be carried out on a periodic basis. This update process is normally performed after the online service ends to prevent data inconsistency.

Previously, if this update process did not work properly for some reason and was reprocessed, or the amount of updates itself was large and it was not possible to finish all of them by the time the online service starts the next day, the online service will start. The time was delayed or some processing was carried over to the next day.

[Problem to be solved by the invention]

The above-described conventional online system operation method has the disadvantage that if the integrity of the data in the data file is respected, the online start time will be delayed to unrelated parts, which is inconvenient for the user.

On the other hand, if the update processing is to be terminated even though all the processing has not been completed yet, and the unprocessed portion is carried over to the next day, there is a drawback that the operation becomes difficult.

[Means to solve the problem]

The online partial service device of the present invention includes a management table for managing whether partial service is possible, and a management table for allowing partial use of data files on a storage device connected to a host computer system. a file management unit that manages files based on a managed state;
a data collection unit that receives notification from an update unit that updates a data file whether or not to start a service for that file; a management table update unit that updates a management table based on information collected by the data collection unit; and a display device that displays and outputs the current level of service.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In FIG. 1, in this embodiment, a data processing device 1
0 and the storage device 2 connected to this data processing device 10
0, a display device 30, and a storage device 20.
is a data file 21 that provides information online,
It has a file management table 22 that manages whether the data file can be serviced online or whether the file is being updated, and a file management section 23 that manages the use of the data file based on the information in the file management table. . The data processing device 10 has a data file 21
A file management unit 11 updates the data based on external data or predetermined daily processing, a data collection unit 12 receives information such as whether or not the file is updated from the file update unit, and the data collection unit 12 collects The display device 30 has a function of monitoring the state of the management table.

The file update unit 11 updates the data file 21 every day after the online system is finished. If all updates are completed by the next morning, the data file 21 can be made available to users, and the online system will start normally the next day.

However, if a device failure occurs during an update and it takes a long time to recover, even if no unexpected situation such as a failure occurs, the amount of updates scheduled for that day may be large and may not be completed by the next morning.

Therefore, when a unit of update ends, the file update section 11 notifies the data collection section 12 of the end each time. The data collection unit 12 collects data and notifies the management table update unit 13 of the data. The management table update unit 13 updates the management table 22 based on the notified information. Management table 2
2 has information on which data file is to be updated for each update unit. If the online system is started before all updates have been completed, there is a risk that conflicts will occur if the data files 21 that have not been updated are allowed to be referenced or updated by the user.

Therefore, at the time of starting online, the file management unit 23 refers to the management table 22, and prohibits the user from using the data file 21 from the online system for which all scheduled update units have not been completed.

On the other hand, updates that have not been completed even after the online system has started are continued by the file update unit 11, and each time an update unit is completed, the data collection unit 12 is notified, and the management table update unit 13 updates the management table 22 for the corresponding update unit. All parts of the corresponding data file are made available. On the other hand, the management table update unit 13 updates the update table 22
Every time the file management unit 23 updates the update table 22
It is checked whether there is any data file 21 that has become available after all scheduled update units have been completed.

If there is, the file management unit 23 cancels the usage prohibited state.

In this way, data files that have been updated are sequentially released to users. The series of processing ends when all updates are completed.

〔Effect of the invention〕

As explained above, the present invention is an online office processing system, and even if the update after the online end is not completed by the time the online starts the next day, the service can be partially started while the unfinished updates are continued. As a result, even in the event of an unexpected accident, online services can be started the next day as scheduled, all schedule updates can be made, and data inconsistencies can be prevented.
