RECOVER DATABASE USING BACKUP CONTROLFILE;
alter database open resetlogs;--若归档模式，用此命令可打开，则忽略以下内容

ALTER SYSTEM SET "_allow_resetlogs_corruption"=TRUE SCOPE=SPFILE;--加隐藏参数，不一致验证启动
ALTER DATABASE OPEN RESETLOGS;
ALTER SYSTEM RESET "_allow_resetlogs_corruption" SCOPE=SPFILE SID='*';--隐藏参数回复默认
--3
alter system set "_allow_resetlogs_corruption"=true scope=spfile;--设置隐藏参数
recover database using backup controlfile;
alter database open resetlogs;
shutdown IMMEDIATE;
startup force mount;
alter database open resetlogs;
