在客户环境中，使用了Oracle 10.2.0.4 DataGuard技术，通过最大可用性模式进行数据保护。
以下简单测试，当备库关闭后，再重启备库，主库及备库的响应过程。
在备库执行如下步骤：
SQL> shutdown immediate;
ORA-01109: database not open
Database dismounted.
ORACLE instance shut down.
SQL> startup mount;
ORACLE instance started.
Total System Global Area 1610612736 bytes
Fixed Size 2084400 bytes
Variable Size 385876432 bytes
Database Buffers 1207959552 bytes
Redo Buffers 14692352 bytes
Database mounted.
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
Database altered.
SQL> exit
当备库关闭后，主库立即检测到备库的失败：
