Wang Hong-an · Jisuanji gongcheng yu sheji · 2008
There are little resources such as memory and CPU in embedded real time environment,and data is often destroyed by unex-pected failures and disasters.An effective recovery subsystem is designed for E-RTDB based on the specialty of the embedded real time environment,including log manager,checkpoint,recovery,etc,and a dynamic adaptive checkpoint algorithm taking system performance and recovery functionality into account is proposed,the disaster recovery problem is successfully solved.Tests show that it has a good performance.
