PURPOSE: To automate system management and tuning by using a system for data arrangement determination and a system which determines which process request executing computer respective process requests are allocated to on the basis of the history of the respective process requests at the same time, and making them cooperate with each other.
CONSTITUTION: This data processor consists of (m) computers 110-1 110-m for process request execution, a computer 111 for front-end processing, a coupling path 114 which mutually connects the front-end computer 111 and respective process request executing computers 110-1 110-m, and data storage devices 118-1-118-m which are connected to the respective process request executing computers 110-1-110-m and store data. Those computers perform parallel data processing with high performance and the loads of the process requests are decentralized to cope with highly-loaded data processing. Then a process request allocation part 101 obtains information on the execution history of past process requests and selects the computers 110-1-110m as allocation destinations on the basis of the information.
