aging, when it is performed in cluster system, system reliability can
be significantly increased. We firstly presented a software rejuvenation
policy of application sever cluster. Then we set up a software rejuvenation
model in two-dimension state space for a two-node application server cluster
and give the quantitative analysis using continuous time Markov process.
Finally, the numerical experiment results show that the selected optimal
software rejuvenation interval can greatly reduce expected systematic
downtime and improve software reliability of application server cluster.]]>Avritzer, A. and E.J. Weyuker,199725977Bao, Y.J., X.B. Sun and K.S. Trivedi,200554541548Dohi, T., P.K. Goseva and K.S.
