ABSTRACT:
In cases where the system which performs service provision includes plural kinds of OS, the plural kinds of OS are operated simultaneously on one standby server provided with the virtual control unit. When a failure etc. occurred in the operation system server necessitates the system switchover from the operation system server to the standby server, the virtual control unit of the standby server distinguishes an operation system server in which the failure has occurred, and takes over the processing to the switching control unit on a suitable OS on the standby server.
