Abstract
Dual-server hot-standby can implement a good task-reliability, so it is used in power system broadly. This paper proposes a new dual-server hot-standby system technology for real-time database, implements modular hardware based on technologies including testing and monitoring the state of system and resources, state synchronous, network communication, mechanism of switching over and data mirror service. Main control modular monitors and arbitrates the state of dual-server, and network communication modular monitors whether server breaks down. Switch over modular switches whenever the server breaks down, and configuration modular sets information about switch over. It ensures that the system runs in a good task-reliability.关键词
