<p><P>PROBLEM TO BE SOLVED: To notify a notice registration request origin of data change even when the data change is first notified to a redundant server different from the notice request for the data change. <P>SOLUTION: This communication system is provided with a first client which changes data, and notifies any redundant server of data change and a second client which notifies any redundant server of the change in changing the data of the first client. Also, this communication system is provided with a storage means for storing notice registration information showing a redundant server to be registered from a second client in association with the client information. When a notice registration request is made from the second client, each redundant server sets notice registration information in the storage means, and when data change is notified from the first client, each redundant server notifies the second client to be determined by the notice registration information, of the data change. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
