JPH04105137A - Check system for input/output function of computer - Google Patents

Abstract

PURPOSE:To easily check the input/output function of a computer at the daily start up of a computer system by storing previously a test program in a memory and writing/reading the data for check of the input/output function of the computer. CONSTITUTION:An arithmetic processor 2 is provided together with a memory device 3 storing a check program 5, an input/output controller 4, the input/ output file devices 7a-7c, and the check files 8a-8c. Then an input/output function check means works with start of the program 5 to read and write the check data and to perform the collation between the read and write data. Thus it is possible to obtain a computer input/output function check system that can be easily carried out every day.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a computer input/output function check method [Prior Art] Conventionally, computer systems are subject to periodic maintenance at regular intervals, and the input/output functions of the computer system are checked. A test program was used to check the input/output functionality of the computer system.

[Problem to be solved by the invention]

In the conventional computer input/output function check method described above, a test program was loaded from the outside during periodic maintenance performed at regular intervals, and various input/output function checks were performed using the test program. This is complicated and cannot be done each time the computer system is started up. When starting up the computer system every day, the system must be started up on the assumption that the input/output functions of the computer system are normal. However, if you start up the system and start work without realizing that the input/output function has failed, it may cause serious business problems. There was a problem.

An object of the present invention is to provide a computer input/output function checking method that can be easily implemented on a daily basis.

[Means to solve the problem]

The computer input/output function check method of the present invention includes a check file provided in a storage means for checking the input/output function, writing check data into the check file, reading the check data, and performing the check process in the check file. It has input/output function checking means for checking read data and write data.

〔Example〕

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

FIG. 1 is a block diagram of an embodiment of the present invention.

The computer input/output function check method shown in Figure 1 is as follows:
Arithmetic processing unit 2, memory device 3 storing check program 5, input/output control device 4, input/output file device 7a
~7CN Consists of check files 8a to 8c.

Next, the operation will be explained.

In FIG. 1, it is assumed that a check program 5 is stored in the memory device 3 of the computer main body 1, which checks the input/output functions and starts the business if there is no abnormality. By starting the check program 5, an input/output function check means functions to write check data into the check files 8a to 8c, read the check data, and compare the read data with the written data. The input/output control device 4 is connected to input/output file devices 7a to 7C, and the input/output file devices 7a to 7b have check files 8a to 7b for writing and reading data to check input/output functions. 8b is stored.

When the check program 5 stored in the memory device 3 is started, the input/output function checking means functions, and the input/output function checking means checks the checking file 8a in the input/output file device 7a via the arithmetic processing unit 2. Write data to. Then, when data writing is completed normally, the next written data is read out. If the reading is also completed normally, the write data and the read data are compared, and if the result of the comparison is that they match, the check on the input/output file device 7a is finished.

Then, the above-mentioned series of operations and checks are performed on all the check files from the check file 8a in the input/output file device 7a to the check file 8c in the input/output file device 7C, and the input/output function of the computer system is verified. Check.

In this way, if everything is operating normally, it is confirmed that the written data and read data match, and the input/output functions of the computer system have been checked, then the business can be started with peace of mind.

〔Effect of the invention〕

As explained above, the present invention stores a test program in memory in advance and provides a check file for reading and writing data to check the input/output functions, so that it can be used at the time of daily startup of a computer system. This has the effect of being able to easily check input/output functions.
