Abstract

PURPOSE:To quickly restore a communication processor, when a fault occurs, which performs processing on receiving an execution program transferred from a host computer. CONSTITUTION:The execution program transferred from the host computer 1 when the communication processor is started up is loaded on memory 23 by an execution program loading means 22, following that, it is registered on a program file 28 by a program file registering means 24. When an instruction to sample fault information from the host computer 1 is accepted, a memory content collating means 25 collates the execution program in the memory 23 with the one in the program file 28, and samples a different part. A fault information transfer means 26 transfers the address of the different part and the content of the memory to the host computer 1 as the fault information. After the transfer is completed, an execution program re-loading means 27 re-loads the execution program on the memory 23 from the program file 28.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication processing device failure recovery system, and more particularly to processing of information with a connected terminal device by an execution program transferred from the host computer at the time of start-up, and with the host computer. The present invention relates to a communication processing device failure recovery method for recovering a communication processing device that performs communication when a failure occurs.

[0002]

2. Description of the Related Art Conventionally, this type of communication processing device failure recovery system uses a host computer to send an instruction from a console of a host computer so that all the memory contents stored in the main memory of the failed communication processing device are stored in the host computer. After the transfer, the execution program is transferred again according to an instruction from the console of the host computer, and the fault communication processing device is restarted.

[0003]

In the conventional communication processing device failure recovery method described above, the transfer time increases as the number of execution programs of the communication processing device increases, and the restart instruction is complicated by the manual operation of the maintenance personnel. Therefore, there is a problem that it takes time to recover. Further, since all the memory contents are transferred to the host computer, there is a problem that it takes time to analyze the cause of the failure.

[0004]

SUMMARY OF THE INVENTION A communication processing device failure recovery system of the present invention uses a communication processing device that communicates with a host computer by performing processing by an execution program transferred from the host computer when the communication processing device is activated. In the communication processing device failure recovery method according to claim 1, an execution program loading means for loading an execution program received from a host computer together with a boot instruction into a memory, and an execution program loaded after the execution program loading means loads the execution program to an external storage device. A program file registration means for registering / storing as a program file in the computer, an execution program loaded in the memory by the execution program loading means in response to a failure information collection instruction from the host computer, and the program file registration means Memory content collating means for collating the execution program registered as a program file and extracting different portions, and fault information for transferring the addresses and memory contents of the different portions extracted by the memory content collating means to the host computer as fault information. It comprises a transfer means and an execution program reload means for loading the contents of the program file into the memory after the transfer by the failure information transfer means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, 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 embodiment of FIG. 1 shows a host computer 1 and a communication processing device 2 connected by a communication line. The host computer 1 includes a host console 11 and a failure information file 1.
2 is connected to an external storage device, and the communication processing device 2
Is an instruction receiving means 21, an execution program loading means 22,
An external storage device having a memory 23, a program file registration means 24, a memory content verification means 25, a failure information transfer means 26, and an execution program reload means 27, and stores a program file 28, and a plurality of terminal devices 2.
9 is connected.

In the above configuration, when the system is started,
The system operator uses the host console 11 to access the communication processing device 2
Command to start. The host computer 1 transfers the execution program to be processed by the communication processing device 2 and its load instruction to the communication processing device 2 in accordance with the activation instruction. When the instruction receiving means 2 receives the load instruction, the communication processing device 2
The execution program loading means 22 is activated. The execution program loading means 22 loads the execution program transferred from the host computer 1 into the memory 23. Execution program loading means 2
When the data No. 2 has been loaded into the memory 23, it activates the program file registration means 24. The program file registration means 24 registers the contents loaded in the memory 23 in the program file 28. When the program file registration means 24 notifies the instruction acceptance means 21 of the end of registration,
The instruction receiving means 21 notifies the processing means (not shown) of the start of execution of the processing, and the processing as the communication processing device is started.

When the system operator knows a failure of the communication processing device 2 during communication through the host console 11, the system operator gives an instruction to collect information of the communication processing device 2 from the host console 11. The host computer 1 transfers this instruction to the communication processing device 2. When the instruction receiving unit 21 receives the information collection instruction, the instruction receiving unit 21 transmits the instruction to the memory content collating unit 25. The memory content collating means 25 collates the execution program stored in the memory with the content of the program file 28 saved at the time of startup, and passes the different points together to the failure information transferring means 26. The failure information transfer means 26 uses the information received from the memory content verification means 25 as
As shown in the format diagram of FIG. 2, the address portion 201 at different locations and the memory value portion 20 indicating the memory value at that time
It is created in the fault information 200 having 2 and is transferred to the host computer 1. The host computer 1 stores the received failure information 200 in the failure information file 12 for later failure analysis. On the other hand, the fault information transfer means 2
When the transfer of the failure information 200 is completed, 6 notifies the execution program reloading means 27 of the completion of the transfer. When the execution program reloading means 27 receives the transfer end notification,
The execution program stored in the program file 28 is loaded into the memory 23, and after the loading is finished, the loading acceptance is notified to the instruction receiving means 21. The instruction accepting unit 21 notifies the processing unit of the resumption of the execution of the process and restarts the process.

[0009]

As described above, according to the present invention, in the communication processing device, the save file of the execution program is compared with the execution program in the main storage device and the execution program in the save file at the time of a failure, and the different parts are checked. When a failure occurs in the communication processing device, only the information necessary for failure analysis is transferred to the host computer when a failure occurs in the communication processing device by providing means for transferring the saved file to the host computer. Since it reloads and restarts booting, there is an effect that failure recovery can be performed in a short time and failure analysis in the host computer becomes easy.
