WANG QIAN, LIU NAIJIA, YUAN FANG. Design and Realization of University Database Emergency Response System. [J]. 2012, 58(S1): 91-94. DOI: 10.14188/j.1671-8836.2012.s1.019.
Since the construction of disaster tolerant system is not only complicated but also costly
in this article
we analyze all kinds of technologies for database disaster tolerancy and design a set of economical and practical database emergency response system which can achieve good results.That is to say
when unrecoverable fault occurs in database server or storage
the application system can be switched to emergency response database without being amended.
