[Effect]

In the communication failure management method for an information processing device according to the present invention, the temporary suspension means temporarily suspends data communication control with all the communication processing devices when a failure occurs in the data communication control, and the information collection means temporarily suspends data communication control with all the communication processing devices. Collects information regarding a failure in the data communication control that was temporarily interrupted, and the data transmission path closure command issuing means performs data communication control when a failure occurs in the data communication control based on the information collected by the information collecting means. A data transmission path closing command is issued to the communication processing device that was being used, and data communication with other communication processing devices is continued.

〔Example〕

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

FIG. 1 is a block diagram showing the configuration of an online system to which a communication failure management method for an information processing apparatus according to an embodiment of the present invention is applied. This online system includes an information processing device 1 and communication lines 21, 22, .・

The information processing device 1 includes a communication control section 11 and a communication operation section 12.
, a communication failure management section 13 , a failure management section 14 , and a communication processing device control table 15 , to which a failure management file 16 is connected.

The communication failure management section 13 includes an information collection means 131 and a data transmission path closure command issuing means 132.

The fault management section 14 is configured to include a temporary suspension means 141.

FIG. 2 is a diagram showing the configuration of the communication processing device allocation table 15. The communication processing device control table 15 includes communication processing devices 31, 32, . ..., 3n entries, and each entry includes a communication processing device 31, 32, . ...
3n name, a flag indicating that data communication is being controlled, and communication processing devices 31, 32. ..., control information for controlling communication with 3n are stored.

Next, the operation of the communication failure management system of the information processing apparatus of this embodiment configured as described above will be explained.

Communication business department 12 and communication processing device 31.32. ...,
3n and communication lines 21, 22. ..., 2n, respectively.

For example, when controlling data communication between the communication processing device 31 and the communication business unit 32, the communication control unit 11 sets a flag indicating that data communication is being controlled in the entry of the communication processing device 31 in the communication processing device control table 15. and register control information.

If a data communication control failure occurs while the communication control unit 11 is controlling data communication between the communication processing device 31 and the communication business unit 12, the communication control unit 11 sends a message indicating the failure type (data communication control) to the failure management unit 14. A code indicating the fault type (failure type) indicating that the fault is a fault is passed to the fault management unit 14, and control is transferred to the fault management unit 14.

The failure management unit 14 to which control has been transferred determines from the code passed from the communication control unit 11 that the failure is in the data communication control, and uses the temporary interruption unit 141 to interrupt the communication processing device 31.
32. . . . The data communication between the 3n and the communication business unit 12 is temporarily interrupted, and control is transferred to the communication failure management unit 13.

In the communication failure management section 13 to which control has been transferred, first, the information collection means 131 is activated.

The activated information collection means 131 stores the data area (not shown) used by the communication control unit 11 and the communication processing device control table 15 in the fault management file 16, and also stores the communication processing device 31 according to the flag of the communication processing device control table 15. The data transmission path closing command issuing means 132 determines that a failure has occurred in the data communication control for the
