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