A load balancing method comprises the steps of: registering a business configuration definition of each business service including a schedule of the business service with a business configuration management repository; storing at least a service level objective of each business service; storing information on performance of each information processing module; acquiring the registered schedule and the stored service level objective of the designated business service; partitioning the schedule of the designated business service into a plurality of partial schedules according to the acquired service level objective; selecting one or more information processing modules whose performance information stored in the performance management table satisfies the service level objective in each partial schedule; and reserving the information processing modules selected for the partial schedules as information processing modules for executing the designated business service in the schedule. A partition fulfilling agreements on service quality can be constructed dynamically.

System and method for load balancing based on service level objectives and information on the contents of start and finish processes of business services

A design supporting method for an information processing system having a plurality of apparatuses connected via a network. Identification information of each apparatus is acquired through network connection from a network configuration design supporting apparatus. Schedule information of each identified apparatus is acquired from a storage unit and compared with a reserved time period of the information processing system, and an apparatus unavailable in the reserved time period is extracted. Identification information of each substitute apparatus for the extracted apparatus is acquired from the network configuration design supporting apparatus, schedule information of the identified substitute apparatus is acquired from the storage unit and compared with the reserved time period, and information of a substitute apparatus available in the reserved time period is output to support a change in each apparatus.

This invention is for a relatively loose recovery of data still not backed up at the time of a failure by later inputting it. A recovery method of recovering processes at a data center when a failure occurs at another data center during execution of the process, has a step of transmitting data at a first data center normally used to a second data center at a predetermined interval and backup at the second data center; a step of, when the first data center breaks down, selecting an information processing apparatus of which recovery time including a time for inputting data not backed up satisfies a requested recovery time, from the second data center; and a step of deploying applications used at the first data center in the selected information apparatus and recovering the data from the backup.

A device for moving a cleansing nozzle connected to a water supply system includes an elongated nozzle, a cylinder in which the nozzle is axially slidable, a motor having an output shaft, a drum body mounted on the output shaft, the drum body having a cylindrical rim surface and a sectoral recess extending from the surface, a sectoral insert disposed in the recess and having a partial cylindrical surface conforming to and forming a continuation of the cylindrical rim surface, and a leaf spring having one end connected to the nozzle and the other end held between the drum body and the sectoral insert such that rotation of the drum body extends and withdraws the nozzle longitudinally as the leaf spring unwraps and wraps around the drum body. The method includes counting the number of cycles of the frequency of the electric power supplied to the motor, determining the actual position of the nozzle on the basis of the counted pulses, establishing a predetermined position of the nozzle, comparing the actual position with the predetermined position, and transmitting the results of the comparison to a power circuit for the motor to turn the motor on and off so that the motor thereby positions the slidable nozzle at the predetermined position.
