CONSTITUTION:The central processing unit 1 has a response operation registration means 11, a pseudo fault generation means 12 and a log data extracting means 13; and a fault processor 2 has a fault processing means 21, a response operation pseudo means 22 and a log collection means 23. The fault processing is automatically evaluated by the fault processing evaluation program of the central processing unit 1. Thus, the fault processing can accurately be evaluated in a short time without troubling the other persons.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides a central processing unit, and when a failure occurs in the central processing unit, the failure information is collected and stored internally as log information, and the log The present invention relates to an information processing system including a fault processing device that investigates fault details based on information and performs fault handling.

[Conventional technology]

Conventionally, this type of information processing system has had a pseudo failure generation function and a function of automatically implementing various failure processes.

[Problems to be Solved by the Invention] The conventional information processing system described above has a drawback in that it is necessary to manually check the log information left in the fault processing device after the fault processing evaluation is performed.

[Means for Solving the Problems] In the information processing system of the present invention, the central processing unit receives a response that registers, in the failure handling device, operation details for the central processing unit after failure handling according to the target test item of the failure handling device. an operation registration means, a pseudo failure generation means for generating a specified failure in a central processing unit, a log data extraction means for reading log data collected by the failure processing device due to the occurrence of a failure from the failure processing device, and the operation When fault processing evaluation is instructed by the fault processing device according to the content, the fault processing evaluation program starts the log data extraction means and determines whether the fault processing for the test item has been correctly performed based on the read log information. The failure processing device includes response operation simulating means for operating the central processing unit according to contents registered by the response operation registration means.

[Effect]

Since the failure handling evaluation program of the central processing unit automatically evaluates the failure handling, it is possible to evaluate the failure handling quickly and accurately without requiring any human intervention.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic block diagram of an embodiment of the information processing system of the present invention, and FIG. 2 is a flowchart of failure processing in this embodiment.

The central processing unit 1 transfers the operation details from the failure handling unit 2 to the central processing unit 1 after executing the failure handling to the failure handling unit 2.
a response operation registration means 11 for registering in the central processing unit 1; a pseudo failure generating means 12 for generating a simulated failure in the central processing unit 1;
It has a log data siphoning means 13 for reading out log data from the log data.

The fault processing unit 2 includes a fault processing unit 21 that performs fault processing corresponding to the content of the fault that occurred in the central processing unit 1, and a fault processing unit 21 that performs an operation on the central processing unit 1 after executing the fault processing registered in the response operation registration unit 11. The response operation simulating means 22 executes the operation on the central processing unit 1 that has been stored and registered after the fault processing is completed, and is activated by the fault processing means 21,
It consists of a log collection means 23 that collects and stores information about the central processing unit 1 when a failure occurs.

Next, the process from occurrence of a failure to failure handling evaluation in this embodiment will be explained according to the flowchart of FIG. One test item is shown below. The response operation registration means 11 is used to specify the operation details for the central processing unit 1 after the fault processing according to the target test item (in this case, remove the pseudo fault from the central processing unit 1 and restart the fault processing evaluation program). The central processing unit 1 registers the fault in the fault processing unit 2 (step 31), and the fault, which is a test item, is set in the central processing unit 1 using the pseudo fault generating means 12 (step 32). The central processing unit 1 generates a pseudo failure and notifies the failure handling unit 2 of the failure occurrence (step 33).When the failure handling unit 2 receives the notification from the central processing unit 1, the failure handling means 21 It starts the operation and instructs the log collection means 23 to collect failure information of the central processing unit 1. The log collection means 23 collects and stores log data, and returns control to the failure processing means 21 (step 34). After the fault processing means 21 performs fault processing according to the content of the fault, control is passed to the response operation simulating means 22, and the response operation simulating means 22 operates the central processing unit 1 according to the content registered by the response operation registration means 11. Operate (Step 3)
5) The fault handling evaluation program is restarted by the above operation, and a comparison is made with the expected value when the fault handling for the test item is correctly performed.

That is, the necessary information is read out from the fault processing device 2 by the log data extraction means 13 (step 36), and the fault processing result is determined (step 37).

〔Effect of the invention〕

As explained above, the present invention includes a response operation registration means, a log data extraction means, and a failure handling evaluation program in the central processing unit, and automatically evaluates failure handling, thereby eliminating the hassle. This has the effect of being able to accurately evaluate fault handling in a short period of time.
