Abstract

PURPOSE:To prevent fault due to the same case from repeatedly occurring and to prevent restart of an application processing program accompanied with this repeated occurrence. CONSTITUTION:If fault occurs (step 102), fault information is acquired (step 201) and is outputted to a console (step 202) and is stored in a fault information storage file set in an external storage device (step 203). Fault information at the time of the occurrence of preceding fault is read out from the external storage device and is compared with present fault information (step 204). It is checked whether the date of the occurrence of present fault is within a certain time after that of preceding fault or not and whether their data classifications and fault classifications are equal or not (steps 205 to 207); and if repetition of the occurrence of fault and restart of the program is discriminated as the comparison result, the stop of application processing is determined (step 208). At this time, an operating system does not restart the application processing program but performs the stop processing (step 301).

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for restarting a business processing program after a predetermined troubleshooting process when a failure occurs while the business processing program is being executed in an information processing apparatus.

2. Description of the Related Art Conventionally, when a failure occurs while a business processing program is being executed on a computer system or a terminal, the system is restarted according to the procedure shown in FIG. That is, when a failure occurs (step 12) while business processing is being executed by the business processing program 10 (step 11), the failure processing 20 includes the date and time when the failure occurred, the type of data processed by the business processing program, and the occurrence of the failure. Fault information including the type of fault caused is obtained (step 21).
), they are displayed on the console (step 22). Control is then passed to the operating system 30,
The business processing program is restarted (step 31).
), the business processing is restarted by the business processing program 10 (step 13).

[Problem to be Solved by the Invention] However, in such a conventional restart method, after the restart, the business processing program resumes processing from the data at the time of the failure, so the failure may occur again due to the same cause. In this case, the failure occurs and the business processing program is restarted repeatedly, resulting in a state where the business processing does not proceed at all.

[0004] In order to avoid such problems, it is possible to discard data at the time of failure without processing it and restart processing from the next data. There may be cases where normal data that does not meet the above criteria is not processed, and failure to process normal data may adversely affect subsequent processing.

An object of the present invention is to solve such problems by providing information that prevents the occurrence of failures due to the same cause and the subsequent restart of business processing programs, and also ensures that normal data is processed. The purpose of the present invention is to provide a method for restarting a processing device.

[0006]

[Means for Solving the Problems] The present invention provides a method for restarting an information processing device in which when a failure occurs during the execution of a business processing program, the program is restarted after predetermined failure handling. Information collection means that acquires predetermined failure information and stores it in a predetermined storage means when a failure occurs during execution of a program, and the failure information acquired by this information collection means and the previous time read from the storage means. information comparing means for comparing failure information stored when a failure occurs; and restart determining means for determining restart of the business processing program when a comparison result by the information comparing means satisfies a predetermined condition. The present invention is characterized by providing an operating system that restarts the business processing program only when the restart determining means determines the restart.

[0007]

Embodiments Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the processing flow of a computer system based on the restart method of the present invention. This computer system performs business processing using a business processing program 100, and when a failure occurs, executes failure processing 200, and then
The business processing program 100 is restarted by the operating system 300.

To explain in more detail, when a failure occurs (step 102) while the business processing program 100 is processing data input as a business process (step 101), failure information is first acquired (step 201). ). Specifically, this fault information includes the date and time when the fault occurred, the type of data being processed by the program 100 at the time of the fault, and the type of fault that occurred. This fault information is output to the operator console (step 202), and is further stored in a fault information storage file set in an external storage device (step 203).
. This failure information storage file has a capacity to store multiple sets of failure information, and is managed in such a way that when the file becomes full, it is overwritten by returning to the beginning.

Next, the fault information obtained when the previous fault occurred is read from the external storage device and compared with the current fault information obtained in step 201 (step 20
4). Then, it is checked whether the date and time of the current failure is within a certain time from the date and time of the previous failure, whether the data types are the same, and whether the failure types are the same (steps 205 to 207) and compared. If even one of the results is negative, it is determined that failures due to the same cause and restarting of the business processing program will not be repeated, and a decision is made to restart the business processing (step 209), and all comparison results are correct. In this case, it is decided to stop the business process (step 208
).

[0010] Control is then passed to operating system 300, which operates
If it is determined to restart the business process, the business process program is restarted (step 302), and as a result, the business process program resumes processing from the data at the time the failure occurred. On the other hand, if it is determined to stop the business processing, the operating system does not restart the business processing program, but executes post-processing associated with the suspension of the business processing program (step 301).

[0011]

Effects of the Invention As explained above, in the information processing apparatus based on the restart method of the present invention, when a failure occurs during execution of a business processing program, the information collecting means acquires predetermined failure information and performs a predetermined The information comparison means compares the fault information acquired by the information collecting means with the fault information read from the storage means and stored at the time of the previous fault occurrence. Then, when the comparison result by the information comparing means satisfies a predetermined condition, the restart determining means decides to restart the business processing program, and only in that case, the operating system restarts the business processing program. In other words, the restart determining means can identify whether the failure has recurred due to the same cause based on the comparison result by the information comparing means, and as a result, if the failure has occurred due to the same cause, the operating system You can prevent business processing programs from restarting. Therefore, it is possible to prevent failures and repeated restarts due to the same cause. Furthermore, if the failure does not occur again due to the same cause, processing resumes from the data that was being processed when the failure occurred, as in the past, so that data that does not cause recurrence of the failure is reliably processed.
