In a composite system in which a plurality of data base systems and data communication are treated as respective subsystems. At the occurrence of a fault in one subsystem, other subsystems are allowed to operate continuously, thereby facilitating recovery after a faulty subsystem has started up. A controller performs as to which data base system a transaction in execution has accessed so that the range of failure is confined, thereby facilitating the fault recovery. The check points of two processings including updating of information in the memory and accumulation of the updated information in the journal are detected so that the need of journals for information occurring earlier than the check point is eliminated, and a check point dump is acquired without waiting for the end of a transaction which has been active at the check point.
