Abstract

For disaster recovery, many database systems with valuable data have been designed with database synchronization between main and backup sites. The data synchronization interval affects the performability of system which is a combined measure of performance and availability. It is important to determine the optimal synchronization interval in terms of performability so as to satisfy customers' requirements. However, existing techniques to identify the optimal synchronization interval do not consider the performability impacts of time-consuming manual resolution task for inconsistent data. To address this issue, this paper proposes a method to identify the data synchronization interval which optimizes performability by solving a stochastic reward net model describing the manual and automatic failure-recovery behavior of a database system. Several numerical examples are given to demonstrate the proposed method and its potential practical applicability.
