PURPOSE:To switch an on-line processing even when multiple computer systems exist at separated places, by providing input message areas in the multiple computer systems, and storing the input message in which the on-line processing on another computer system is applied. CONSTITUTION:The input message inputted from a terminal equipment 12A is informed to a message discriminating means 4A via a line switching device 11A and a message input/output means 10A. The discriminating means 4A stores the input message in a message storage area 7B from an another system input message reception means in the computer 1B via a message transmission means. When the computer 1A stops due to a fault, a storage message reading means 3B reads out the message in the message storage area 7B, and performs a transaction processing at a message processing means 2B. When the processings of all of the input messages are completed, an operator switches the terminal equipment 12A to the computer system 1B by the line switching device 11A. |
