Abstract
A scheme for restarting processes at distributed checkpoints in a client-server computer system, in which a fault in one client computer does not affect the server computer and the other client computers. In this scheme, a fault occurring in one computer among of a plurality of computers constituting a client-server computer system is detected while these plurality of computers are executing respective processes, and whether that one computer in which the fault is detected is a server computer or not is judged. Then, related processes executed on these plurality of computers are restarted when that one computer is judged as the server computer, whereas no process executed on these plurality of computers is restarted when that one computer is not judged as the server computer. It is also possible to specify a restart information for each process indicating how processes should be restarted when a process fault occurs in each process, and to restart selected processes executed on these plurality of computers according to the restart information for a process in which the process fault is detected.
