Abstract

A large-scale distributed system is constructed step by step over a long period of time. Even under construction, online operation is started in its system. After starting online operation, it continuously has to be tested and maintained in various areas without stopping online operation. In the conventional online test technique for an autonomous decentralized system, the online and the test data exist concurrently in the same system. The real-time response of the online system is not assured. A method in which test/on-line subsystems are clustered and data flow among each cluster is controlled autonomously, thereby isolating each subsystem and protecting it from perturbation from other subsystems, is given. The reliability and real-time response of the online system are ensured with this method
