Abstract:
1. A resource assignment method by a management computer for assigning resources of a physical computer, said resources being used by a plurality of logical computers configured from the physical computer when executing a query request into databases stored in a storage, said plurality of logical computers being configured to function as plural computers when said physical computer executes programs, said resource assignment method, comprising the steps of: partitioning said inputted query request into a plurality of processing phases which are units executable in parallel, calculating resource costs by making reference to memory means for storing cost master information, said resource costs being needed for executing said processing phases of said inputted query request, said cost master information indicating processing contents of said logical computers and resource costs both needed for executing said processing phase of each phase type of said processing phases, receiving said resource costs for said processing phases from said individual logical computers, and storing said resource costs into said memory means on the basis of an access right of said logical computers to said databases, said processing phases being assigned to said individual logical computers, calculating resource assignment ratios of said individual logical computers by making reference to said resource costs stored into said memory means, and by dividing said resource costs for said processing phases assigned to said individual logical computers by summation of said resource costs for said processing phases assigned to all of said individual logical computers, and modifying assignment amounts of said resources of said physical computer in correspondence with said calculated resource assignment ratios, said resources being assigned to said individual logical computers.
