基于Oracle Dataguard的数据同步机制及其实现

摘要

In receives the attention the data to accommodate in the disaster solution, uses what kind of data synchronization mechanism to carry on allows the disaster data synchronization subsystem's design to realize, guarantees operational channel's timeliness and the high usability, so that the greatest degree protection data property security, already became accommodates the disaster system construction highly matter of concern. This article mainly aimed at based on Oracle the DataGuard data storage capacity disaster system's data synchronization mechanism has conducted the exploration research, and carried on to the data synchronization module's design has realized.%在备受关注的容灾解决方案中,采用何种数据同步机制进行容灾数据同步子系统的设计实现,保证业务系统的实时性和高可用性,以便最大程度地保护数据资产安全,已经成为容灾系统建设高度关注的问题.本文主要针对基于Oracle DataGuard数据库容灾系统的数据同步机制进行了探索研究,并对数据同步模块的设计进行了实现.
