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.

Claims

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 a 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 own 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 own equipment, the second information-processing equipment reflects the operation to the second application of the third information-processing equipment, and

wherein when a notice of system switchover is received, said switching control unit specifies a service IP address of an operating system and an application of a switchover destination from a source IP address, sets the service IP address to own equipment, and starts to provide service of the specified application.

2. The information-processing system according to claim 1, wherein said switching control unit is operable to switch over a main operating system of own equipment to the operating system of the switchover destination when the operating system of the switchover destination is different from the main operating system of the own equipment.

3. The information-processing system according to claim 1, further comprising one of a plurality of the first information-processing equipment and a plurality of the second information-processing equipment.

4. The information-processing system according to claim 2, further comprising one of a plurality of the first information-processing equipment and a plurality of the second information-processing equipment.

5. Information-processing equipment comprising a switching control unit and operable to execute a first operating system, a first application to run on the first operating system, a second operating system, and a second application to run on the second operating system,

wherein when a notice of system switchover is received, the switching control unit specifies a service IP address of an operating system and an application of a switchover destination from a source IP address, sets the service IP address to own equipment, and starts to provide service of the specified application.

6. The information-processing equipment according to claim 5, wherein said switching control unit switches over a main operating system to an operating system of the switchover destination when the operating system of the switchover destination is different from the main operating system of the own equipment.

7. The information-processing equipment according to claim 5, wherein said switching control unit sends a notice of start of operation to the sending source of the notice of system switchover when the service of the specified application is started.

8. The information-processing equipment according to claim 6, wherein said switching control unit sends a notice of start of operation to the sending source of the notice of system switchover when the service of the specified application is started.
