When hardware failure occurs in an operation device, a provisional job executing unit of a virtual machine is allowed to temporarily execute a job until setup of a spare device as an alternative job execution device is completed. Start of operation of the virtual machine is performed in a short time by shift from a suspending state to an operating state. Therefore, execution of the job is not stopped by the hardware failure of the operation device and it is possible to improve continuity of the job and improve reliability of a redundant configuration of the job execution device in which the spare device is associated with the operation device.

Operation management device and method for job continuation using a virtual machine

A network monitoring program automatically sorts fault producing locations on a network. A memory unit stores a fault location determining table containing events indicative of failures of communications via the network, the events being associated with classified elements which can be causes of faults on the network. A communication situation monitoring unit monitors communication situations with respect to other apparatus on the network. A failure detecting unit detects an event indicative of a failure from a communication situation detected by the communication situation monitoring unit. A fault location determining unit determines an element which is responsible for the event detected by the failure detecting unit by referring to the fault location determining table. A fault information output unit outputs fault information representative of a determined result from the fault location determining unit.
