Operating method of software fault-tolerant handling system

摘要

An exemplary embodiment provides an operating method of a software fault-tolerant handling system, and more particularly, to an operating method of a fault-tolerant handling system in which a fault recovery is easy in a fault-tolerant technology of copying with various faults which can occur in a computing device.

主权项

1. An operating method of a software fault-tolerance handling system, comprising:
setting a mode of a first processor to an active mode and a mode of a second processor to a standby mode between the first and second processors in accordance with a setting reference; performing a self healing function to recover a system error which occurs in the first processor or transmitting a heartbeat message to the second processor when the system error does not occur; generating a diff app_context between a basic app_context for a predetermined process which is being executed in the first processor and an app_context at a current time and transmitting the generated diff app_context to the second processor, after the transmission; and switching the mode of the first processor to the standby mode and switching the mode of the second processor to the active mode when a current state of the first processor meets a set reference to continuously execute the predetermined process, at the time of transmitting the diff app_context, wherein:
the mode setting includes,calculating a first mode corresponding to an initial mode value calculated based on an init material stored in a memory of the first processor and calculating a second mode corresponding to a current mode value transmitted from the second processor; andsetting the modes of the first and second processors based on the first and second modes and the first setting reference.
