Oracle 12c Data guard 物理主备库正常切换(switchover)流程
1、 在主库上执行下面语句，确认备库是否准备好切换
|
sqlplus / as sysdba
ALTER DATABASE SWITCHOVER TO CHICAGO VERIFY; |
无报错后，进行下面步骤。
2、在主库上执行下面语句，将主库切换到备库，CHICAGO是备库的db_unique_name
|
sqlplus / as sysdba
ALTER DATABASE SWITCHOVER TO CHICAGO; |
3、打开新的主库
|
ALTER DATABASE OPEN; |
4、打开新的备库
|
STARTUP; |
5、在新的物理备库上，打开 REDO APPLY
|
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION; |
