<P>PROBLEM TO BE SOLVED: To select an active-system management program suitable for a situation in which the status of a node or a network dynamically changes even in such a situation with a distributed computer system comprising a plurality of nodes. Ž<P>SOLUTION: When failure occurs in an active-system manager 3, each node 1 constituting this distributed computer system selects a candidate of the active-system manager 3 from a plurality of standby-system managers 3, and transmits a selection result to the selected standby-system manager 3. Each standby-system manager 3 receives the selection result, decides whether or not itself becomes the active-system manager 3 based on the received selection result, and changes into the active-system manager 3 according to a decision result thereof.
