1. An information-processing system comprising:
- first information-processing equipment operable to execute a first operating system and a first application to run on the first operating system;
second information-processing equipment operable to execute a second operating system and a second application to run on the second operating system; and
third information-processing equipment including an operating system switching control unit and operable to execute the first operating system, the first application, the second operating system, and the second application,wherein when said first information-processing equipment accepts operation to the first application of the first information-processing equipment, the first information-processing equipment reflects the operation to the first application of the third information-processing equipment,wherein when said second information-processing equipment accepts operation to the second application of the second information-processing equipment, the second information-processing equipment reflects the operation to the second application of the third information-processing equipment,wherein when a notice of system switchover is received, said operating system switching control unit specifies a service IP address of an operating system and an application of a switchover destination from a source IP address, andwherein when the operating system of the switchover destination is different from a main operating system of the third information-processing equipment, said operating system switching control unit switches over the main operating system of the third information-processing equipment to the operating system of the switchover destination, sets the specified service IP address of the operating system to the third information-processing equipment, and starts to provide service of the specified application of the switchover destination.

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.
