Abstract

PURPOSE:To reproduce the state of a system tracing back to the start point of processing in the case of trouble occurrence and to restore the system to the state right before the trouble occurrence by storing all input data from terminals and saving the data at the time of the start of on-line processing. CONSTITUTION:An on-line data input part 13 inputs data from a terminal 2 or reprocessing control part 9 and outputs them to a service data processing part 14. The processing part 14 processes the input data and updates a service master data base 7 and an environment file 8. The reprocessing control part 9 sends a restoration indication to the restoration part 11 of a data base in response to an indication from an console panel 3 and puts the system back into the on-line service start state. The data inputted from an input data storage processing part 10 are outputted as on-line data to a data input part 13. The input data storage processing part 10 writes the data that an input part 13 passes to the service data processing part 14 in an input data storage file 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to online systems, and in particular to li['iF
This paper relates to an overall reprocessing method for online business operations that restores the environment and reprocesses business data.

[Conventional technology]

Recovery work in the event of a failure in an online system is extremely important.

Conventionally, as reprocessing methods for failure recovery, there are two methods: returning the contents of the database to the state immediately before the failure occurred, and restarting online operations from a certain point and re-entering data from the terminal6 [Invention solves the problem] [Issues to be solved] With the reprocessing method in the conventional online system described above, it is difficult to completely restore the contents of the main storage device and the contents of the environment file, and it is difficult to completely restore the contents of the main storage device and the contents of the environment file. It has the disadvantage that it requires re-input, which requires a large amount of man-hours, and is prone to errors.

SUMMARY OF THE INVENTION An object of the present invention is to provide a system for reprocessing the entire online business in which data input during online business processing is stored separately and used during failure recovery, thereby improving the above-mentioned drawbacks.

Means for Solving Section 0] The entire online business reprocessing method according to the present invention is a recovery bundle of an online system using a computer, which includes an input data storage section that stores online input data in a file, a database, and an environment. It has a database restoration unit and an environment restoration unit that return files to the state at the start of online processing, and a reprocessing control unit that reads input data stored in the input data storage unit and inputs it to online processing.

〔Example〕

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

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

In the figure, the overall reprocessing method for online operations is CP
U. Online data input section 13 on the main storage device 1. Business data processing unit 14. Reprocessing control section 9. Input data storage processing section 10. There is a database restoration unit 11, an environment file restoration unit 12, and an online terminal 2. Operation console 3. Input data storage file 4. Restoration database 5. There are a restoration environment file 6, a business mask database 7, and an environment file 8.

The CPU/main storage device 1 performs control processing and arithmetic processing of each part and each peripheral device, data input/output processing, and data retention.

The online data input section 13 inputs data from the online terminal 2 or the reprocessing control section 9 and outputs it to the business data processing section 14 . The business data processing unit 14 processes the data input from the online data input unit 13 and updates the business mask database 7 and environment file 8.

The reprocessing control unit 9 issues restoration instructions to the database and environment file restoration units 11 and 12 in response to instructions from the console, returns to the online business start state, and converts the data input from the input data storage processing unit 10 into online data. The data is output to the online data input section 13 as . The input data storage processing unit 10 writes the data that the online data input unit 13 passes to the business data processing unit 14 into the input data storage file 4, reads the stored file, and sends it to the reprocessing control unit 9. .

The database restoration unit 11 performs restoration processing on the database 7 according to instructions from the reprocessing control unit 9.

Further, the environment file restoration section 12 performs the environment file 8 restoration process according to instructions from the reprocessing control section 9.

Terminal 2 inputs business data from the keyboard, and
Output to main storage device 1. The operation console 3 controls the CPU/main storage device 1 and gives various instructions to the reprocessing control section 9. The input data storage file 4 is the input data storage processing unit 1
Receives online data from 0, stores it, and outputs this data as online data when reprocessing. The restoration database 5 saves the contents of the database 7 at the time of starting online business. The restoration environment file 6 saves the contents of the environment file 8 at the time of starting online business.

FIG. 2 is an explanatory diagram showing the operation of normal online business processing. In the same figure, the online data input unit 13 receives and receives data input from the terminal 2, and the business data processing unit 14 performs various business processes to update the database 7 and environment file 8 in Mf&. Here, the input data storage processing section 10 writes and saves the data input from the terminal 2 in the input data storage file 4. Note that the database 7 and environment file 8 at the end of the previous online business are saved in advance to the restoration database 5 and the restoration environment file 6, respectively.

If the online system is stopped due to some kind of failure during normal online business processing as described above, the main storage 1. The contents of the database 7, environment file 8, etc. may have been destroyed, and after resolving the problem that caused the failure in order to start online operations again, the above-mentioned destroyed contents will be deleted immediately before the system is stopped. It is necessary to restore the contents.

Furthermore, even when online operations are restarted due to temporary processing, it is necessary to reproduce the same state as when a failure occurred, such as when investigating the cause or checking correction items later.

FIG. 3 is an explanatory diagram showing the operation of file restoration processing.

In the figure, when the operator console 3 instructs to start the restoration process, the reprocessing control unit 9 receives this and instructs the database restoration unit 11 and the environment file restoration unit 12 to perform the restoration process. Each restoration section reads restoration files 5 and 6,
The contents of the database 7 and environment file 8 are restored. In this way, the point at which online business started is restored.

FIG. 4 is an explanatory diagram showing the entire reprocessing operation.

In the figure, the reprocessing control unit 9 receives an instruction to start the entire reprocessing from the console 3, and causes the input data storage processing unit 10 to read the data in the input data storage file 4 one by one, and transfers the data to the online data input unit. 13. The online data input unit 13 passes this data to the business data processing unit 14 in the same way as online data input from an online terminal in normal processing, and performs business processing. This is performed on all data sequentially, reproducing the processing up to the point when the system stopped, and restoring the system's operating state and environment. Here, the state up to an arbitrary point in time can also be reproduced by instructions from the console 3.

〔Effect of the invention〕

As explained above, the present invention saves all input data from a terminal in business processing of an online system,
In addition, by saving the database and environment files at the start of online processing, in the event of a failure that causes the system to stop, the system status can be recreated retroactively to the time when online processing started, and the environment and state immediately before the failure occurred. , can be restored. Furthermore, it is possible to continue the online business by taking over the current state, which has the effect of completely restoring the online business.

Furthermore, by reprocessing the entire system using the method of the present invention after correcting the cause of the failure, it is possible to check the operation of the corrected part and also perform a degradation check of the part that was normal until now. Furthermore, if the input data storage file is saved, it is possible to repeat the reproduction test at a later date without having to input the same data from the online terminal as at the time of ffIF. Therefore, not only can a large number of man-hours spent on testing be reduced, but also it is possible to avoid incomplete reproduction tests due to data entry errors.
