Research and Implementation of Dual-Server Hot-Standby of Configuration Software

Aiming at the design characters of configuration software of host monitoring system, the paper brings forward dual server hot-standby software implementation solution based on host and slave way. The conversion of control power, the backup of real-time and history data, synchronization problem and so on are researched and solved in the solution. Simulation of various failure experiments and actual operation on "the static dust monitoring system of Dalian electronic research institute" proves that the solution works steadily and reliably, and the state transforms levelly and smoothly. The system can satisfy most functional requirements of monitoring systems for dual-server hot-standby software
