<p><P>PROBLEM TO BE SOLVED: To provide a fail-over method, a system thereof, a node, and a program such that information used to decide whether to shift from a standby system node to an in-use system node is made consistent between standby system nodes. <P>SOLUTION: In the fail-over method, when each standby system node detects a fault occurring to an in-use system node, information on the standby system node itself at a certain point of time after the fault detection of the in-use system node is transmitted to other standby system nodes, information on the standby system node itself and information on the other standby system nodes are acquired, and it is decided whether to shift from the standby system node to an in-use system node by using the acquired information on the standby system nodes. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
