<P>PROBLEM TO BE SOLVED: To provide a distributed computing system where catch-up of a processing state of an information processor is dynamically and autonomously performed. <P>SOLUTION: Respective information processors L, A, B include a catch-up data request means 51 for requesting return of the catch-up data of the information processor when transmitter maximum operation serial number data are larger than self maximum operation serial number data, and a catch-up data returning means 54 for returning the catch-up data in response to the return request of the catch-up data. The respective information processors which have received the catch-up data perform catch-up processing of a database by applying an operation command corresponding to the catch-up operation serial number data to data of the database by the operation execution means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
