PROBLEM TO BE SOLVED: To dynamically reallocate all resources allocated to one virtual computer to the other virtual computer. SOLUTION: Of LPAR control parts 6 for controlling virtual computers LPAR which are respectively logically sectioned resources, the LPAR control part 6 of the LPAR shifting to an inactive state stops the OS of the corresponding LPAR and instructs the release of the resource of the corresponding LPAR and the reallocation of the resource to the other LPAR to a resource management part 8 for managing the resources. The LPAR control part 6 of the LPAR to which the resource is to be newly allocated stops the OS of the corresponding LPAR and reads new allocation contents from the resource management part 8. When a channel is additionally allocated, it is reconstituted. When the using rate of an instruction processor IP is added, the rescheduling of the IP is requested to a monitor 9. Or a new logic processor is generated and allocated to the corresponding LPAR. Then, the OS of the corresponding LPAR is activated together with the new allocation contents of a main storage MS.
