Abstract

PURPOSE:To attain the automatic output of the dump output of a main storage to another auxiliary storage with no intervention of an operator by providing a dump output control mechanism which works under the control of a system supervisory mechanism. CONSTITUTION:When a system fault is detected during the control of a program P1, a program control mechanism PC 2 sends the information on the system fault to a system supervisory mechanism SC 3. Then the SC 3 instructs a dump output control mechanism DPC 5 to prepare for the dump output and then gives a stop instruction to the PC 2 after the dump output is prepared. Then the SC 3 gives a dump output instruction to the DPC 5. Based on this instruction, the DPC 5 outputs the information on a main storage 4 to a magnetic disk device 6. The SC 3 gives an instruction again to the PC 2 to start the system supervisory and the program control.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a memory dump output control method, and in particular, in order to know the contents of the main storage device in the event of a system failure of an information processing device, the present invention relates to a memory dump output control method. The present invention relates to a memory dump output control method that automatically controls so-called memory dump output, in which contents are transferred, recorded, checked, etc.

[Conventional technology]

Conventionally, in this type of memory dump output control method, when a system failure occurs, the information processing device displays a system failure message, the operator confirms the message, and backs up the message to an auxiliary storage device for backup. I inserted the medium, pressed the dump output switch on the main storage, and transferred the dump output information to the backup auxiliary storage.

[Problem to be solved by the invention]

In the conventional memory dump output control method described above, an operator had to output a dump from the main memory every time a system failure occurred, so it was necessary to manually output a dump from the outside to the control system that was processing information. This method has the drawback that it is necessary to interrupt the output operation, and it is not possible to output an appropriate dump at the time of a system failure.

SUMMARY OF THE INVENTION An object of the present invention is to provide a memory dump output control method that can monitor a system and automatically stop information processing operations and perform memory dump output operations when a failure occurs.

[Means to solve the problem]

A memory dump output control method of the present invention includes a main storage device that stores programs and data of the information processing device;
A program control unit that loads programs and data into the main storage device and detects system failures, monitors system operation of the information processing device, and recognizes information on detection of system failures in the program control mechanism. The system includes a system monitoring mechanism, a dump output control mechanism that dumps and outputs information in the main storage device based on instructions from the system monitoring mechanism, and an auxiliary storage device that stores the dumped information.

〔Example〕

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

FIG. 1 is a block diagram showing one embodiment of the present invention. The embodiment shown in FIG. 1 includes an information processing device 1, a program control device n12 that controls programs, a system monitoring mechanism 3 that monitors the system of the information processing device and detects system failures of the program control mechanism 2, and a program and data system. a main storage device 4 for storing information, a dump output control mechanism 5 that dumps information in the main storage device when a system failure is detected;
It consists of a magnetic disk device 6 for storing dumped information.

Next, the operation of this embodiment will be explained. First, the program control mechanism 2 loads, for example, the program itself of the program P1 and the data of the program P1 into the main storage device 4, and performs program control. When the program control mechanism 2 detects a system failure while controlling the program P1, it notifies the system monitoring mechanism 3 of information on the system failure. The system monitoring mechanism 3 instructs the dump output control mechanism 5 to prepare for dump output, waits for completion of the dump output preparation, and then instructs the program control mechanism 2 to stop program control.

Based on the instruction, the program control mechanism 2 notifies the system monitoring mechanism 3 that the program itself has been stopped. The system monitoring mechanism 3 instructs the dump output control mechanism 5 to start dump output. Dump output controller n
Based on the instruction, ll5 outputs the information in the main storage device 4 to the magnetic disk device 6, and when the output operation is completed, notifies the system monitoring mechanism 3 of the completion. System monitoring machine! M3 instructs the program control mechanism 2 to resume system monitoring and start program control. Here, the auxiliary storage device is not limited to a magnetic disk device, but may be any other recording medium depending on the purpose of troubleshooting or the like.

〔Effect of the invention〕

As explained above, the present invention provides a dump output control mechanism that operates under the control of the system monitoring mechanism, thereby automatically outputting the dump output of the main storage device to another auxiliary storage device without operator intervention. It has the effect of allowing you to perform actions.
