Abstract:
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:
