发现报错了,因为我备份了控制文件和数据文件,然后开库新建了一个表,导致数据库的日志文件和控制文件的scn不一致了,查看alter日志
进入startup mount执行
recover database until cancel;
alter database open resetlogs;
startup mount ——进入到mount
SYS@PROD> recover database until cancel;——不完全恢复
Media recovery complete.
SYS@PROD> alter database open resetlogs;——重置日志
Database altered.
SYS@PROD> select open_mode from v$database;——数据库已经打开
