Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is utilized for a synchronous memory dump information collection method for information processing devices and communication processing devices in a data communication network.

〔overview〕

The present invention provides a synchronous memory dump information collection method in which a network synchronous dump control program means is provided in the storage program control means of each communication processing device to request a memory dump based on a synchronous memory dump request from an operator or communication processing device. By generating a command and transmitting it to the relevant center via a communication line, a synchronous memory dump request can be easily notified to the relevant center within a short period of time after a failure occurs, ensuring accurate synchronization. This allows valid memory dump information to be collected.

[Conventional technology]

Conventionally, the synchronous memory dump information collection method has adopted a method in which a system operator contacts each center by telephone or the like and collects memory dump information of information processing devices and communication processing devices for each center.

Generally, in order to investigate the cause of a failure in a data communication system, memory dump information of information processing devices and communication processing devices is collected and analyzed.

In conventional data communication systems, it has been possible to investigate the cause of a failure by collecting and analyzing memory dump information from information processing devices and communication processing devices in one center. However, this memory dump information is only information for one center in the data communication network, and memory dump information for other remote centers cannot be obtained. I was imagining.

In recent years, as the configuration of data communication networks has become more complex, analyzing the memory dump information of the information processing equipment and communication processing equipment of one center is insufficient to investigate the cause of failures that occur within the data communication network. Memory dump information tends to be in short supply, and synchronized memory dump information at the same time of information processing devices and communication processing devices of other centers within a data communication network has become necessary.

[Problem that the invention seeks to solve]

However, this conventional synchronous memory dump information collection method requires human effort and is therefore time-consuming.
In addition, it is difficult to achieve accurate synchronization, and it takes time to collect memory dump information after a failure occurs, making it impossible to collect effective information necessary to analyze the cause of the failure.

The present invention solves the above-mentioned drawbacks, and is capable of easily notifying the corresponding center of a synchronous memory dump request within a short time after the occurrence of a failure, and collecting valid memory dump information through accurate synchronization. The purpose of this paper is to provide a synchronous memory dump information collection method that can be used.

[Means for solving problems]

The present invention provides a method for collecting synchronous memory dump information.
The communication control program means includes means for outputting a synchronous memory dump request when an abnormality is detected during data transfer, and the storage program control means outputs a synchronous memory dump request from the operator from the information processing device or outputs the synchronous memory dump request. The apparatus is characterized in that it includes network synchronous dump control program means for generating a memory dump request based on the output of the means and transmitting it to a corresponding center via a communication line.

[Effect]

The network synchronous dump information of the storage program control means generates a memory dump request command based on the operator's synchronous memory dump request from the information processing device or the synchronous memory dump request from the communication control program means, and controls the communication line. The information will be forwarded to the relevant center and its operator will be notified.

That operator collects memory dump information at the same time as other operators. Through the above-described operations, a synchronous memory dump request can be easily notified to the corresponding center within a short time after the failure occurs, and valid memory dump information can be collected with accurate synchronization.
