解决办法:

alter database recover managed standby database cancel;

shutdown immediate
3.启动数据库到mount状态
startup mount
4.清除报错的日志组5
ALTER DATABASE CLEAR UNARCHIVED LOGFILE GROUP 5;
5.应用日志
alter database recover managed standby database using current logfile disconnect from session;
6.日志应用完后先退出然后再打开数据库
alter database recover managed standby database cancel;
alter database open;
7.再次应用日志
alter database recover managed standby database using current logfile disconnect from session;
