| 摘 要： | 利用服务器群集，将多台服务器和数据存储单元连接成一个易于管理的高可用性单元，群集内的一台服务器出现故障后，服务器群集会及时调度另一台服务器来接管服务，最大限度的实现了不间断服务。而DATAGUARD是在主节点与备用节点问通过日志同步来保证数据的同步，以实现数据库快速切换与灾难性恢复，进一步确保了数据库的安全性。

| Abstract: | Using server cluster, the server and the data storage are connected into a high manageable availability unit, when a server works failure, server cluster will promptly dispatch another server to take over the service,it maximum ensured the service uninterrupted. While the DATAGUARD is in a master node and a standby node through the log synchronization to ensure the synchronization of data, in order to achieve database fast switching and disaster recovery, to further ensure the security of database. |
