Abstract

PURPOSE:To prevent the same abnormal recovery processing from being repeated by storing and displaying the processing state of the system by a prescribed flag, and selecting a processing program to be executed according to the value of the flag. CONSTITUTION:The flag F for storing the processing state of the computer processing system, a self-diagnosis of the processing state is performed to set a value for identifying the processing state in the flag F, and a processing program 100 to be executed is selected according to the value of the flag F. Thus, the prescribed flag F stores and displays the processing state of the computer processing system and the processing program 100 is selected according to the value of the flag F, so proper processing is performed according to the processing state of the system and the same processing is not repeated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a processing function self-judgment method for automatically determining the processing function of a computer processing system by itself and dealing with abnormalities.

[Conventional technology]

Generally, when a processing program executed on a computer processing system detects an abnormality in its own operation, it simply stops its operation.

or ■Perform predetermined abnormality recovery processing for certain types of abnormalities.

Such a method was adopted.

[Problem to be solved by the invention]

In particular, method (■) above is very effective because it allows processing to be performed again after the abnormality recovery process is completed, but depending on the type of abnormality, the exact same abnormality may reappear.
In that case, exactly the same abnormality recovery process is performed, resulting in a drawback that the same process is repeated many times.

The present invention has been proposed in view of the above points, and its purpose is to provide a processing function self-judgment method that can perform appropriate processing depending on the type of abnormality, that is, the processing state of the system. There is a particular thing.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a flag for storing the processing state of a computer processing system, self-diagnoses the processing state, sets a value for identifying the processing state in the flag, and sets the value of the flag to a value that identifies the processing state. The processing program to be executed is selected accordingly.

[Effect]

In the processing function self-determination method of the present invention, a predetermined flag stores and displays the processing state of the computer processing system, and a processing program to be executed is selected according to the value of this flag.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic configuration of an embodiment of the processing function self-judgment method of the present invention. In FIG. 1, 100 is a processing program executed on a computer processing system, including a normal processing program 101 that performs normal processing, and a normal processing program 101 that performs abnormality recovery processing when an abnormality occurs during normal processing or special processing to be described later. an abnormality recovery processing program 102 that performs normal processing or special processing, an interruption recovery processing program 103 that performs interruption recovery processing after normal processing or special processing is interrupted (for example, forced termination due to a power outage), and an interruption recovery processing program 103 that performs interruption recovery processing when there is an abnormality in the computer processing system that cannot be recovered. and a special processing program 104 that performs special processing. Note that special processing refers to pseudo-normal processing that can be safely executed even on an abnormal computer processing system, such as performing the minimum processing that is originally performed by normal processing. Specifically, for example, if normal processing involves converting and transmitting a received message, special processing is processing such as discarding the received message and transmitting an error message.

On the other hand, F is a flag for storing the processing state of the computer processing system, and 200 is a flag for self-diagnosing the processing state of the computer processing system and setting a value for identifying the processing state in the flag F, as well as for pre-processing. This is a processing execution control unit that has a function of selecting a processing program to be executed by referring to flag F. Note that the flag F is stored independently of the processing function to be determined; for example, EEP
It is stored on a storage area such as a ROM or a magnetic disk. Further, the relationship between the processing state of the computer processing system and the value of the flag F, and the relationship with the next process to be executed are as shown in FIG.

FIG. 3 is a flowchart showing the operation of the above embodiment, and the operation will be explained below with reference to FIG.

When the process starts, the value of flag F is first determined in steps 1 and 9. If F-0 (last time ended normally), step 2, and if F=1 (last time ended due to interruption), step 15. If F=2.3°4 (the previous time was abnormal and cannot be recovered after interruption), proceed to step IO.

In step 2, flag F is set to 1, and the process moves to step 3, where normal processing is performed. Note that the reason why flag F is set to 1 in step 2 is to set the contents of flag F to 1 when normal processing is interrupted due to a power outage, etc. 0 Then, normal processing in step 3 is set to 1. If it is executed, the process moves from step 4 to step 8, and in step 8, the flag F is set to 0, and the process ends. Also, if an abnormality is detected during normal processing in step 4, the process moves to step 5 and abnormality recovery processing is performed, and if recovery is performed, the process moves from step 6 to step 8, which is the same as if it was normal. Processing ends. If recovery is not possible, the process moves to step 7, sets flag F to 2, and ends the process.

On the other hand, in step 15, an interruption recovery process is performed, and if the recovery is performed, the process moves from step 16 to step 18, the flag F is set to O, and the process returns to step l. If recovery is not possible, the process moves to step 17, sets flag F to 4, and ends the process.

On the other hand, special processing is performed in step 10, and step l
If the special processing of O is executed normally, step 11 is passed and the processing ends with the value of flag F unchanged. Also,
If an abnormality is detected during the special processing in step 11, the process moves to step 12 and abnormality recovery processing is performed, and if the recovery is performed, the extraction is performed from step 13, and the processing ends with the value of flag F unchanged. . If recovery is not possible, the process moves to step 14, sets flag F to 3, and ends the process.

〔Effect of the invention〕

As described above, in the processing function self-judgment method of the present invention, a predetermined flag memorizes and displays the processing status of the system, and a processing program to be executed is selected according to the value of this flag. Appropriate processing is executed, which has the effect of eliminating the inconvenience of repeating the same abnormality recovery processing as in the past.
