解决方法1 重做 physical standby

这个比较简单,粗暴,不适用数据库偏大的情况.

解决方法2 恢复 physical standby

这个比较通用,也比较简单

从库上操作,启动到mount状态,启动恢复

SQL> shutdown immediate;
SQL> startup mount;
SQL> recover managed standby database using current logfile disconnect from session;

主库上操作,产生几个归档

SQL> alter system archive log current;
SQL> alter system checkpoint;
SQL> alter system archive log current;
SQL> select * from v$archive_dest where destination is not null;

一定要求确保 v$archive_dest 的 status 列为 ‘VALID’

在主库上查询一下归档情况：

SQL> select name,sequence#,archived,applied from v$archived_log order by sequence#;

如果返回结果 ‘APPLIED’ 都是 ‘YES’ 或者只有最后一个是 'NO’的话，说明全部归档日志全部已经归档完了.
备库上操作

SQL> alter database recover managed standby database cancel;
SQL> alter database open;

此时,如果数据库正常打开了,且如果是通过 sqlplus 手动配置的 dataguard,就执行如下命令

SQL> alter database recover managed standby database using current logfile disconnect from session;

如果是通过 dataguard broker 配置的,就直接进入 dgmgrl 操作.

DGMGRL> show configuration ;
