PROBLEM TO BE SOLVED: To provide an information processing system performing switching, wherein the stop period of a service is shortened as much as possible even when system switching fails due to a program failure. SOLUTION: A remote machine 200 is provided with a database 210 in which generation-managed software and its definition are stored and a database 220 in which the operation result of each program is associated with each other, and a first device as a current system and a second device as a stand-by system are provided with system switching functions 11 and 21, respectively, having restoration destination information storage parts 14 and 24 and program restoration functioning parts 12 and 22 having failure-categorized restoration tables 15 and 25. When the system switching to the second device is operated due to the program failure of the first device, a failure program is restored in a third device. When the system switching fails due to the generation of the identical failure of the second device, the processing is switched to the third device being the restoration destination of the program.
