Abstract
A maintenance system for a wide area work-flow system in which plural work-flow systems operates with linking via a wide area network. A historical information management unit is connected to the wide area network and maintains operation history information for each of the plural work-flow systems operating automatically according to the work-flow defining a processing job flow. When a work-flow system of the plural work-flow systems recovers from system-down, mismatch or discrepancy is detected by comparing the historical information of the work-flow system with the historical information of the other work-flow systems of the plural work-flow systems. To improve the reliability, the operation history information stored in the historical information management unit is used when the work-flow systems are recovered from system-down.
