掉电后控制文件版本号不一致如何解决
我做了如下操作 现在 alter database open 一直报错ORA-01113: file 1 needs media recovery
ORA-01110: data file 1: '/data/orcl/system01.dbf'
我没有做冷备，但是redolog 都是掉电那天的 我备份了。请问能否补救？
用版本高的控制文件覆盖了低版本的控制文件
SYS@biap> startup mount
ORACLE instance started.
然后
SYS@biap> recover database until cancel

怎么用redolog恢复呢 我有点菜。
recover datafile 1;
然后选择 filename？ 然后又6组redo日志我怎么用呢 ，劳烦指点下
