Abstract

PURPOSE:To prevent the increase of the memory capacity and the disk capacity by selecting the trace information based on the trace control telegram received from a host to store these trace information and therefore acquiring the fault information with limitation. CONSTITUTION:A main control part 12 analyzes the telegram reported from a communication control part 11 and received from a host and the input information reported from an input/output control part 16 and received from a display device. Then the part 12 reports the process requests to a trace analyzing part 13 and a work processing part 14. The part 13 reports a trace processing part 15 with a trace control telegram whether the traces should be acquired or not for each module of the part 14, etc. The part 15 stores and records the trace information into a memory or a disk device by the trace report. Thus the fault information can be acquired in accordance with the fault state and therefore the extra information having no relation with the fault is never acquired. Thus it is possible to acquire the fault information for a long period of time without increasing the memory capacity and the disk capacity.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a terminal device in an online system, and relates to a method for obtaining fault information when a terminal fault occurs.

[Conventional technology]

As described in Japanese Patent Application Laid-Open No. 59-139439, conventional terminal devices store the memory contents when a terminal failure occurs as failure data, collect it in another system through manual operation, and store it as failure data.
We were investigating the cause of the problem.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, in a device where a terminal is composed of a large number of modules and these devices communicate in a complex manner to realize business operations, a large amount of failure information is generated, and the amount of memory and disk capacity is increased to store the failure information. . Furthermore, it takes time to manually intervene and output fault information to other terminals after a fault occurs, and the terminal operations during this time update the memory state at the time of the fault, making it impossible to accurately understand the fault situation. was there. The present invention makes it possible to limit the fault information acquired when a fault occurs according to the fault phenomenon, prevent increases in memory and disk space, extend the time from fault occurrence to fault information output, The purpose is to reduce the number of updates to fault information.

[Means to solve the problem]

In order to achieve the above purpose, a trace means is provided, and each module requests the trace means to trace the information necessary for failure analysis as trace information, and the trace means receives the trace information in chronological order according to the trace request from each module. is stored in the trace area.

Further, the tracing means obtains a trace control message from the host, selects and accumulates trace requests from each module according to a module-by-module trace acquisition instruction instructed by the trace control message.

[For production]

Each module constantly requests tracing for information necessary for failure analysis. The trace command analysis unit analyzes the trace control message from the host, and notifies the trace execution unit of whether or not a trace is to be acquired for each module. The trace execution unit selects a trace request from each module and stores only necessary information in accordance with the trace presence/absence notification from the trace command analysis unit. Such an operation makes it possible to prevent unnecessary information from being accumulated.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a configuration diagram of an online system.

In the figure, 1 is a terminal device connected to 2 terminals via 3 communication lines.
Connect to host computer. In addition, 4 CPUs can load 5 programs from 9 floppy disks or disk devices.
By being read into the memory and executed, it controls communication adapter 6 to communicate with the host computer, controls display adapter 8 to perform screen display on display device 1o, and performs online business.

FIG. 2 is a block diagram showing the module configuration of a program within the terminal device. 11 communication control unit controls communication with the host computer and transmits the message received from the host to 12
Notify main control unit. The 16-person output control section is connected to 10 display devices via 8 display adapters, receives input information from the display devices, and communicates it to the main control section. The main control unit analyzes the received message from the host notified by the communication control unit and the input information from the display device notified by the input/output control unit, and analyzes the request processing unit 13 trace analysis unit and 14 business processing. Notify department of processing request. The trace command analysis unit notifies the 15 trace processing unit whether or not to perform trace acquisition for each module based on the content of the trace control command regarding the trace control message. In addition, the business processing unit is a processing unit that executes online business, which is a function of the terminal device.There are multiple business processing units depending on the business, and these processing units, communication control units, and input/output control units communicate with each other. Perform designated tasks. Each module in the terminal device, such as each business processing unit, issues a trace request to the trace processing unit using communication information with other modules as trace information. In response to trace requests from each module, the trace processing unit stores trace information in response to trace requests from modules that have been instructed to enable tracing in 5 memories, 9 floppy disks, or disk devices based on trace notifications received from the trace analysis unit. and record it. Trace information is not stored in response to a trace request from a module that has received an instruction not to trace.

FIG. 3 is a format diagram of the trace control message transferred from the host. The main control unit recognizes that the message is a trace control message based on the message type at the beginning of the message, and notifies the trace analysis unit.

The trace control command following the message type is from module 1 to
The presence/absence of trace for n is held in this order, and is sequentially transmitted from the trace analysis section to the trace processing section. The trace processing unit manages trace presence/absence on a memory basis for each module.

〔Effect of the invention〕

According to the present invention, since it is possible to acquire failure information according to the failure situation, there is no need to acquire unnecessary information unrelated to the failure, and the amount of memory and disk capacity that is the failure information area does not increase. Therefore, fault information can be obtained for a longer period of time.
