摘要: Abstract Redundant disk arrays provide a way for achieving rapid recovery from media failures with relatively low storage cost large scale database systems requiring high availability. In this paper we propose method using redundant to support system crashes and transaction aborts in addition their role providing failure recovery. A twin page scheme is used store the parity information array so that time commit processing not degraded. Using an analytical model simulation results, show proposed achieves significant increase throughput of by reducing number operations needed maintain consistency database.
