Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a failure diagnosis analysis method for hardware of an information processing system of an electronic computer or an electronic exchange.

(Prior Art) Regarding failure diagnosis for hardware of an information processing system such as an electronic exchange, there is a method of automatically performing the diagnosis based on an instruction such as a command from a maintenance person. Regarding this type of failure diagnosis, rapid failure and repair is required as electronic switching equipment and the like become faster and more diverse, and as services become more diversified. Therefore, in order to centralize maintenance personnel and facilitate maintenance work, work such as equipment diagnosis is performed centrally at a location remote from electronic exchanges, etc., and information output as a result of diagnosis is also It has become necessary to directly analyze and output the package product name, etc., which is the suspected failure location of the device, through software processing. Conventionally, in the diagnosis method for the above system, the diagnostic processing instructed by the maintenance person from the additional system, which is a remote maintenance device, is analyzed by program processing in the main system such as the electronic exchange, and a message is sent to the additional system. The method used was to output the information as follows.

(Problem to be Solved by the Invention) However, in the device with the above configuration, in order to directly analyze and output the package, etc. that is the suspected failure location in the diagnostic process, it is necessary to include the product name, mounting position, and additional information (comments, etc.) of the package. If a large amount of data information is required as a diagnostic dictionary, and maintenance work is performed on multiple main systems using an additional system, a diagnostic dictionary is required for each main system, and a large amount of memory is required for the additional system. Ta.

For this reason, it is required to centralize the diagnostic dictionary on the additional system side, and there is a method of analyzing the diagnostic dictionary of the additional system using test data or the like that is diagnostic result information. However, since information such as device failure information and device status (test data) of the main system is sent to the additional system at the same time as the diagnosis result information, if the additional system is monitoring and maintaining multiple main systems, The amount of information is large, and the disadvantage is that complex software processing is required to extract the desired diagnostic result information and perform diagnostic dictionary analysis.

The present invention aims to improve the above-mentioned drawbacks.

(Means for Solving Problems) The present invention provides a configuration in which monitoring and maintenance work of the main system is performed on the additional system side, and in order to analyze diagnostic processing, diagnostic dictionaries are concentrated and deployed on the additional system side, and the memory capacity is It aims to simplify the analysis process as well as eliminate the problem.The feature is that the information processing system is adds diagnostic dictionary analysis information to the diagnostic result information as additional information and sends it to the additional system, which performs remote diagnostic dictionary analysis processing and outputs the processing results based on the additional information. It's in the method.

(Function) Since the main system sends only the diagnosis results and additional information to the additional system, less information is sent than in the past. The additional system analyzes the diagnostic dictionary and outputs the processing results based on the information sent from the main system. Therefore, simple analysis processing can be realized with slight changes compared to conventional systems.

(Example) Examples of the present invention will be described.

FIG. 1 shows an overall configuration diagram of the present invention, and FIG. 2 shows an example of diagnostic result information and additional information for diagnostic dictionary analysis output from the main system.

In Figure 1, the processing program for device diagnosis is placed in the main storage file memory (FM) 4 of the main system (ESS) 1, and the diagnostic dictionary file is placed in the main storage disk unit (DK) of the attached system.
It is placed at 6.

When a device failure occurs in the main system, the failure information is notified to the additional system and output to the supervisory control console (STD) 7. Based on the fault information, the maintenance worker inputs commands from the supervisory control console (STD) to diagnose the suspect device in the main system.

When diagnostic processing is executed in the main system and a faulty package is discovered as a result of the execution, additional information 2 for diagnostic dictionary analysis is added along with test result information (hereinafter referred to as test data) 1, as shown in Figure 2. Send to the system side.

Additional information 2 consists of a code that logicalizes the device type a in which a failure was discovered as a result of diagnosis, the diagnosis execution phase b, the test number, and the test result c, and can be easily identified from the device failure information sent to the additional system. A special code is added to make it possible.

In the case of additional information 2 in Figure 2, device type a is
06000101 indicates that the test result of test number 109 in diagnosis execution phase b of 02 is NG.

The additional system extracts the additional information with the special code mentioned above from the information string sent from the main system, reads the diagnostic dictionary file of the disk unit (DK) 6, analyzes it using the additional information, and determines the product name of the suspect package, Outputs the mounting position etc. to the monitoring operation console (STD).

(Effects of the Invention) As described above, according to the present invention, it is possible to easily perform dictionary analysis processing by placing a diagnostic dictionary file in an additional system that monitors and maintains the main system, and it is possible to easily perform dictionary analysis processing. It is possible to reduce the amount of data and simplify analysis processing.

In particular, this method installs an additional system with a diagnostic dictionary file in a system that conventionally outputs only test data that is the execution result of diagnosis, and maintenance personnel search a diagnostic dictionary and extract suspect packages. By adding an additional information function to the diagnostic processing program, it is possible to easily implement dictionary analysis with a small amount of changes.

[Brief explanation of drawings]

Fig. 1 is a block diagram showing an embodiment of the main system and an additional system for monitoring and maintaining the main system according to the present invention, and Fig. 2 shows information sent from the main system to the additional system as a diagnosis execution result.
