<P>PROBLEM TO BE SOLVED: To prevent transmission of a software image from occupying resources of a server currently used for a long time. <P>SOLUTION: When a repository device 2100 adds a server 2310 to an existing cluster, it instructs each of addition object servers to acquire fractions obtained by dividing a software image into N fractions from a server currently used, which already holds the software image. The addition object server which has acquired the fractions acquires fractions which it does not hold yet from other addition object servers, and transmits the fractions which it holds to the other addition object servers. Fraction exchange processing like this will be repeated until they acquire all the fractions which compose the software image. <P>COPYRIGHT: (C)2012,JPO&INPIT |
