ABSTRACT:
A stand-by system replicates a program module to an active object and a passive object. During execution of operations of the active object, when the active object fails, operations continue to be executed in the passive object. There is provided a checkpoint period memory for storing a checkpoint period, a detecting unit for detecting whether an internal state of the active object has been changed according to the checkpoint period, a consistency maintaining unit for maintaining consistency of the internal state between the active object and the passive object when the internal state has been changed, and a checkpoint period changing unit for increasing the checkpoint period when the internal state has not been changed.
