【Abstract】 This paper describes a reliable and efficient data concentrating system (DCS) based on the triggers, log tables and an algorithm that can update remote data reliably. The DCS running under UNIX includes two parts: data capturing module and data sending module, respectively. The main contribution of the DCS is that it is independent of specific application, so it can gather all applications data transparently. Moreover, the DCS can detect the availability of network and remote host automatically and tolerate many unexpected defaults such as a host crashing, network breaking suddenly, etc.更多还原
