Abstract

PURPOSE:To attain the quick and accurate recovery without wasting a file area by automatically acquiring only the data dump to which the update information is not correctly reflected after execution of an application. CONSTITUTION:The input data on an item is read at the end of a file A 3 and the data having the same keys are retrieved out of a data base 5 for the key items. Then the input data and the master data retrieved out of the base 5 are copied to a file B 4. An application is executed and the updated master data is copied to the file B 4. A data check program is started and the update data is applied to an arithmetic formula with an update data item name obtained by an application used as a key. The contents of the key item applied to the arithmetic formula are compared with the contents of the same key items of the master data. If these contents are identical with each other, they are written into the base 5 and the contents of files are erased. If both contents are not coincident with each other, the master data is copied to the base 5 and the same master data is stored in the file B 4.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a system having a file device, and more particularly to a trouble-checking method for its applications.

(Prior Art) Conventionally, in order to recover from an application problem, dumps were saved before and after executing a database application run, and each dump was referenced after the application ended.

(Problems to be Solved by the Invention) The nine conventional methods described above have the disadvantage of wasting file area because all the contents of the database are copied twice.

An object of the present invention is to dump the contents of a database before and after execution for each piece of processed data when an application is executed, in order to recover from application troubles in a system that has a file device. It is an object of the present invention to provide an application engine trouble check system that eliminates the above-mentioned drawbacks by automatically acquiring only a dump, and is configured so that file areas are not wasted.

(Means for Solving the Problems) The application trouble check system according to the present invention includes a dump means and an automatic dump data acquisition means.

The dumping means has a file device and is rounded to dump the contents of the database before and after execution for each piece of processed data when an application is executed, in order to recover from a problem with the application cage.

The zero-shift dump data acquisition means is for automatically acquiring only the dump of data whose update information is not correctly reflected when the dump is executed.

(Example) Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows the application troubleshooting according to the present invention.
FIG. 2 is a block diagram showing an embodiment of a check method.

In FIG. 1, 1 is a processor, 2 is a terminal, 3.4 is a file (A) and a file (B), respectively, and 5 is a database.

The file (A) 3 is an input data file for executing an application, and the database 5 is a master file for storing data to be updated in the file (A) 3.

File (B) 4 is a file for data copying,
File (A) 3 and database 5 each have a key item, and the data key of file (A) 3 and the master data key of database 5 are the same.

On the processor 1, a program according to the present invention is started and data before and after application execution is checked.

Figure 2 shows the application troubles shown in Figure 1.
This is a flowchart showing the execution method J[t- of the check method.

In the first step, one piece of input data is read at the end of the file (A) 3, data with the same key is searched from the database 5 from the key field, and the input data and the master data searched from the database 5 are transferred to the file (A). B)
Copy to 4.

In the second step, the application is executed, and in the third step, the updated master data after execution of the application is copied to file (B)4.

In the fourth step, using the updated data item name by the application as a key, the same key item of the input data is entered into the same key arithmetic expression stored in the data check program.

In the fifth step, the content of the key item applied to the arithmetic expression in the fourth step is compared with the content of the same key item in the master data copied in the third step.

If they are the same, the master data copied in the third step is written into the database 5, and the input data and master data copied in the first step are erased. If the contents are different, the master data copied in the third step is erased, the master data copied in the first step is copied to the database 5, and the same master data is saved in the file (B) 4.

In the 6th step, the 1st to 5th steps are transferred to a file (A
) Repeat until the data in 3 is exhausted.

Here, if the same transaction appears multiple times, duplication is not allowed.

(Effects of the Invention) As explained above, the present invention automatically acquires only data dumps that do not correctly reflect update information after executing an application, thereby eliminating wasted file space. This has the effect that database master data can be recovered quickly and accurately.

Claims (1)

[Claims] In order to recover from application troubles by having a file device, there is a dump means for dumping the contents of the database before and after execution for each piece of processed data when the application is executed, and updated information is correctly reflected when the dump is executed. An application trouble checking method comprising: an automatic dump data acquisition means for automatically acquiring only a dump of data that has not been dumped.
