The aim of this article is to find an efficient method to detect fault in dualdatabase server which is working on critical environment real time system (such aspower and water distributed environment).In traditional dual database server the fault tolerance is embedded in eachserver. So when there is any defectiveness, each server try to uncover the error inseparate way. This led to increase the load on each server and job lateness.This paper proposes a central fault tolerant method for dual database serverthrough a centralized control, so that the fault will be more controlled andmanipulated and the load will be less in each server since problems detection andcorrection will not depend on dual server but it will be centralized.It showedpractically how the dual server worked under fault conditions and criticalenvironment such as distributed real time systems.
