Abstract

PURPOSE:To realize the collective control of both system date and operation date by designating a changing time point of the operation date and changing the operation date when a standard timepiece is coincident with said changing time point. CONSTITUTION:An operation date part 9 sets the operation date data 51 which is used for operation of jobs and an operation date changing part 11 changes the data 51 when the coincidence is obtained between the designated operation date changing time point data 50 and the data on a standard timepiece 1. The part 9 is controlled by an operating system OS like a system date part 3 and automatically changed as long as the system power supply is secured. Thus a work program is not required to control dates nor to supply the dates for each start of operations.

Description

[Detailed Description of the Invention] [Summary] The operation date used for business operations is set by inputting data to the current date when the computer system starts operating.

The present invention provides a method of specifying the change time of the operation date and managing the date on which the operation date is changed when the standard clock matches this change time.

[Industrial application field]

The present invention relates to an improvement in a date management method in a computer system.

In computer systems used for business, batch processing such as aggregation for the current day may be performed at night when the date is changed, but the operational date for business is used to process data for that day. Ru.

This operation date data is entered at the start of operation on that day,
Dates managed by business programs are managed by being set in a table or in a job control statement of the business program.

For this reason, there are problems such as setting errors in the one-day development burden for business programs, and a date management system is required that collectively manages the operation date along with the system date.

[Conventional technology]

FIG. 3 shows an explanatory diagram of the conventional date management system.

Computer systems are usually equipped with a standard clock, and the operating system OS sets a standard date (based on Greenwich Mean Time; hereinafter referred to as the system date).
, elapsed time, hourly intervals, etc., and services the time requests of the program.

On the other hand, in an i-work program that performs aggregation processing for -days,
The specified date is configured to process data for the minute, and the operational date is used in case the data for that day is batch processed at night when the date (system date) is changed. .

Therefore, at the start of operation, the date of the day is updated by inputting data, and the date data is set in a table included in the business program or in a parameter in the job control statement of the business program.

FIG. 3 is an explanatory diagram of the above-mentioned date management system, and shows an example of changing the balun "-date" of a job control statement. In the figure, l is a standard clock (Time) that counts the standard clock.

f Day; TOD clock), 2 is the date change section, 3
is a system date section that is provided in a memory (not shown) managed by the operating system and in which the date is set.

In addition, 4 is the operation date provided as a parameter in the job control statement, and 5 is the input operation date as data 51.
The operation date is set in part 4. The date is the setting part, and 6 is the determination response part, which determines whether the date requested by the program is data, system date, data 53, or operation date, data 51. .

In the above configuration, when the computer system starts operating, the system date is set to data 53 from the console 8, and thereafter, the standard clock 1 and date change unit 2 update the system date to data 53 unless the power is turned off. To go.

- The labor federation date data 51 is input as a job control statement at the start of the day's operation, and unless there is a change input, the operation date data 51 set in the operation date section 4 will not be changed.

When the date is required in business program 7, for example when batch processing the day's transactions at night, 5vC
(Supervisor call) The operation date is data 5 due to the command.
1, the date determination response unit 6 determines this command, reads the operation date unit 4 (job control statement), and responds to the business program 7.

Thereby, the business program 7 extracts the day's transaction data etc. from the file and performs batch processing.

Note that in a system in which the business program 7 manages the data 51 for the date of operation, a table is provided in the business program 7 and the date of operation is set from the console 8 .

[Problem that the invention seeks to solve]

In the conventional setting of the operation date, it is necessary to input the operation date of the day at the start of the operation on that day, and there is a problem that input errors may occur.

Furthermore, the method by which business programs manage dates has the problem of placing a burden on the development of business programs.

In view of the above problems, the present invention sets the operation date to the system 8.
The purpose of this is to provide a simple date management method that is centrally managed by the operating system O3 along with the 4-dimensions.

[Means for solving problems]

For the above purpose, the date management method of the present invention is as shown in the block diagram of the management unit in the embodiment of FIG. part (9), the specified operation date changes the data (51) when the change time data (50) and the standard clock (1) data match.The operation date changes the data (51). It has been established that

[Effect]

When the change time of the operation date is set and the standard time matches the change time of the operation date, the operation date data 51 set in the operation date section 9 is changed based on the calendar.

The operation date section 4 is managed by the operating system O3 in the same way as the system date section 3, and is automatically changed unless the system power is turned off.

As a result of the above, there is no need for business programs to manage dates, and there is no need to input dates each time an operation is started.

〔Example〕

Embodiments of the present invention will be described with reference to FIGS. 1 and 2.

Fig. 1 is a block diagram of the management unit for the date set in the operating system O8, and 11 shows the set operation date by comparing the change time 50 and the standard clock (TOD clock) 1 data (data omitted below). When they match, the operation date is changed to the change section 9. The operation date is changed to the change section 10. The operation date input from the console 8 is notified to the change time data 50, the operation date is notified to the change section 11, and the system date is changed to the change section 10. The date for setting the data 53 is the setting section; 9 is the operation date provided in the memory area managed by the operating system O8; and the same reference numerals as in FIG. 3 represent the same objects.

The operation will be explained below with reference to FIG.

(1) When the system is running, the system date is data 53
At the same time, the operation date data 51 and the operation date change time data 50 are inputted from the console 8.

As a result, the operation date data 51 is set in the operation date section 9, and the operation date and change time data 50 are notified to the operation date change section 11.

(2) The date change unit 2 compares the standard clock 1 and the system date change time data 52, and if they match, the system date change data 53 is changed to the next day based on a calendar (not shown), and the operation date is changed. The section 9 changes the system date by referring to the section 3 (or calendar) for the system date when the change time data 50 and the standard clock 1 match.

(3) When there is an inquiry from Business Program 7,
The date determination response unit 6 determines whether it is a system date or an operation date, and responds to the business program 7 by referring to section 3 for the system date and section 9 for the operation date, respectively.

As described above, it is possible to provide a date management system in which the operating system O8 centrally updates the system date and the operation date, and there is no need for a business program or an operator to intervene as in the past.

〔Effect of the invention〕

Since the present invention provides a date management method in which the operating system centrally manages the system date and operation date, the development burden of business programs is reduced to 1 day, and the effect of preventing setting errors is extremely large. be.
