我在" MOUNTED"中有备用数据库(版本:Oracle Database 11g企业版版本11.2.0.1.0)。模式。
SQL> select database_role,open_mode from v$database;
DATABASE_ROLE OPEN_MODE

PHYSICAL STANDBY MOUNTED
当我想从" MOUNTED"更改OPEN_MODE时到#34;只读应用"模式,将发生错误(ORA-01093)。
SQL> SHUTDOWN IMMEDIATE;
ORA-01109: database not open
Database dismounted.
ORACLE instance shut down.
SQL> STARTUP MOUNT;
ORACLE instance started.

我们之前已将数据库从版本10g(10.2.0.4.0)升级到11gR2(11.2.0.1.0),然后为了使用Active Data Guard,兼容参数必须至少设置为11.0.0。 兼容参数的当前值为10.2.0.4.0,如以下查询所示:
SQL> show parameter compatible
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
compatible string 10.2.0.4.0

您正在以普通挂载方式启动数据库
让我们说您处于会话断开连接模式下的自动恢复...
然后,您将停止恢复,然后以只读模式打开
android.databinding.incremental=true
然后将自动恢复置于
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
ALTER DATABASE OPEN READ ONLY;
