ABSTRACT:
In order to improve the unbalance of loads imposed on individual database servers at the time of executing individual SQL processing phases, a management computer partitions an inputted query request into the processing phases which are units executable in parallel, calculates resource costs needed for executing the processing phases, assigns the processing phases to the logical computers on the basis of an access right to databases, calculates resource assignment ratios of the individual logical computers in correspondence with the resource costs for the processing phases assigned to the individual logical computers, and assigns assignable resources of a physical computer to the individual logical computers, the assignable resources being equivalent to resource assignment amounts corresponding to the resource assignment ratios.
