Abstract: In order to further shorten the UnionPay online transaction system failure recovery time, this paper puts forward to use six Sigma DMAIC methods, including the use of statistical analysis and quality management method and combining the actual production run, proposes effective analysis method for system fault, establishes sustained and effective improvement mechanism about the online transaction high availability. Test results show that this system failure recovery time in 60 seconds is increased from 88% to 93%.
