Patent number: 9235492Abstract: A load information acquiring unit (230) sets load information based on the history that is acquired by a process history acquiring unit (220). A test period determining unit (240) sets a test period based on the load information. The test period is a period during which a test policy can be used. The test policy is a policy for a test out of control policies used by an information processing system (100). A system control unit (260) measures performance capability of the information processing system (100) under the test policy as a test result by testing the test policy under a production environment of the information processing system (100) by using the test policy instead of a practical policy that is actually used in the test period. A policy changing unit (270) changes the practical policy based on the test policy in a range in which the test result satisfies a reference.Type: GrantFiled: January 21, 2011Date of Patent: January 12, 2016Assignee: NEC CORPORATIONInventor: Yoshihiro Kanna
