  • Publication number: 20080178182
    Abstract: A computer system has a dual structure including a current system and an auxiliary system. When the current system stops because of server down, a setting module of the auxiliary system acquires an operation log and an operation management procedure from the current system and analyzes the operation log to specify to which part of the operation management procedure has been completed. The setting module performs comparative analysis of the operation log of the current system and communication log. The setting module extracts, from a result of the comparative analysis, information for returning the auxiliary system to a state of work at the stop of the execution of the current system. To resume the stopped work, the setting module sets the information in the auxiliary system.
