Abstract

PURPOSE:To enable programming only by the original processing of service by providing a service processing part which performs the original processing of the service and a data base control part which performs processing characteristic to a data base accessed in the processing. CONSTITUTION:This system consists of the service processing part 1, the data base (DB) control part 2, a service DB3 and a control DB4, the service processing part 1 performs the original processing of the service, and the DB control part 2 performs the processing characteristic to the DBs. When a DB is accessed by a service application program (AP), the result is passed to the DB control part 2 first and the control is passed to the service processing part 1 after deadlock processing or as it is. Thus, the service AP which uses the DBs is divided into the original processing part of the service and the processing part characteristic to the DBs and the latter is offered to enable only the original processing of the service to be programmed, thereby decreasing the man- hours for programming.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a recontrol method, particularly in controlling a business application program (hereinafter referred to as AP) that uses a database (hereinafter referred to as DB), to prevent deadlocks and aborts. Regarding the later reprocessing control method.

[Conventional technology]

Conventional reprocessing control methods of this type have incorporated reprocessing logic after DB-specific deadlock and abort into each individual program.

[Problem to be solved by the invention]

In the conventional reprocessing control method described above, processing logic specific to the DB is incorporated into each individual program, so (1) the programmer is required to have DB skills.

■Individual processing logic lacks versatility.

■Program modifications are required due to changes in the DB structure and processing content (also in the DB-specific processing logic).

There is a drawback.

[Means to solve the problem]

The reprocessing control method of the present invention is characterized by having a business processing section that performs the original processing of the business, and a database control section that performs processing specific to the database accessed in the processing.

〔Example〕

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

FIG. 1 is an overall configuration diagram of the present invention, in which a business processing section 1.
DB control unit 2. It consists of a business DB3 and a management DB4.

The business processing unit 1 handles the original business processing, and the DB control unit 2 handles the original business processing.
Perform processing specific to B.

When accessing a DB from a business AP, the result is first passed to the DB control unit 2, and after processing such as deadlock, control is passed to the business processing unit].

FIG. 2 shows the program execution flow. First, in step A, the program control R is created in the management D B 4 , h. Next, in step B, business processing is performed, and if it is successfully completed, the control R created in step A is deleted in step C. In other words, if the process ends abnormally midway, control R remains, and it is determined in step A whether or not the process is to be reprocessed. In the case of reprocessing, the processing is started from the information on control R.

FIG. 3 shows the details of step B in FIG. 2, and the information on the record of the process read in step a or e is saved in control R in step b. If a tedlock occurs in step d or e, the DB
The control unit 2 automatically rolls back and re-executes from step C. In the case of reprocessing after abord 1) After opening B, etc., step a is skipped and processing starts from step C.

〔Effect of the invention〕

As explained above, the present invention provides business A that uses I)B.
By dividing l) into the original business processing part and I) B-specific processing part, and providing the DB-specific processing part,
Programming only for the original processing of business becomes fff-efficient, and there is an effect that the number of conventional programming L can be reduced.
