Patent ID: 7908314

Claim:
A method for controlling a management computer connected to one or more servers for permitting communication therebetween, wherein each of said servers transmits to a client a result of processing for each processing request sent from said client, said method comprising the steps of: storing an allowable relative load value common to all of said servers in said management computer; receiving from each of said servers at said management computer an absolute load value indicative of a countable absolute load on said server calculated on the basis of the number of processing requests received by said server from said client, and a relative load value indicative of a relative load on said server depending on a processing capacity of said server; calculating in said management computer an allowable absolute load value for each of said servers using the received absolute load value, the stored allowable relative load value, and the received relative load value; and transmitting the calculated allowable absolute load value to be used to detect overload of said server to each of said servers, wherein said management computer calculates the allowable absolute load value by multiplying the absolute load value by a ratio of the allowable relative load value to the relative load value.
