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

An operation management device, comprising:

• a processor coupled to a memory,
• wherein the processor is configured to manage operation of a device by executing a process including:
• copying execution conditions of an operation to a storage device, the operation being executed on a first computer;
• creating a virtual machine on a second computer and copying the execution conditions of the operation to the second computer;
• first activating the virtual machine with the execution conditions of the operation on the second computer and making the virtual machine to a suspending state;
• when receiving failure information of the operation on the first computer, second activating the suspended virtual machine with the execution conditions of the operation,
• temporarily making the virtual machine take over execution of the operation during copying the execution conditions of the operation to a spare device for the first computer and starting the execution conditions of the operation copied to the spare device to start the operation, and
• switching from the virtual machine to the spare device to continue execution of the operation when the start of the execution conditions of the operation is completed in the spare device, wherein
• when the starting of the execution conditions of the operation is not completed in the spare device, the making includes continuing the execution of the operation in the virtual machine and increasing an assigned amount of a resource of the second computer to the virtual machine.
