摘要：
In a mirrored database system, good quality of service and high availability is afforded by minimizing the time required for suspension of operations to transition between mirror states, and by keeping track of changes made to a primary database while the mirror database was out of communications so that a later mirror resynchronization process can quickly catch up the mirror database by making only the lost changes.
