Method and apparatus for controlling electric source in information processing system

摘要

A technique allowing a terminal device located in a remote place to protect data existing on an information processing system and then control an electric source of the information processing system is provided. An information processing system according to the present invention includes a service processor for discriminating an order issued by a terminal device located in a remote place, an electric source control circuit for controlling connection or disconnection of an electric source in response to an electric source connection or disconnection order issued by the service processor, and an electric source unit for conducting connection or disconnection of an electric source in response to an electric source connection or disconnection order issued by the electric source control circuit. The service processor discriminates an electric source disconnection order issued by a terminal device located in a remote place, terminates application software under execution effected by the information processing system, and thereafter orders the electric source control circuit to disconnect the electric source. In response to an order issued by the electric source control circuit, the electric source unit disconnects the electric source. Furthermore, in response to such a state that electric power is supplied from the auxiliary electric source at the time of an electric power failure, shutdown processing is conducted and then the electric source is disconnected. The terminal device located in a remote place is notified that the shutdown processing will be conducted.
