ORA-01194: file 1 needs more recovery to be consistent

今天打开的时候不知怎么弄的，不能open了，先是提示数据库没有正常关闭，

 run { startup  force mount ;
2> set until  time "to_date (' 2013-09-26 11:58:58 ',' YYYY-MM-DD hh24:mi:ss')" ;
3> restore database ;
4> recover database  ;
5> sql ' alter database  open resetlogs ' ;
6> }


使用shutdown immediate，等了一会没有结束，于是直接结束了进程，后来又出来一个问题


SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: '/u01/app/oracle/oradata/orcl/system01.dbf'

估计应该是日志的问题，又试了下：
SQL> recover database using backup controlfile until cancel;
ORA-00279: change 669109 generated at 09/12/2009 18:47:00 needed for thread 1
ORA-00289: suggestion :
/u01/app/oracle/flash_recovery_area/ORCL/archivelog/2009_09_13/o1_mf_1_10_%u_.ar
c
ORA-00280: change 669109 for thread 1 is in sequence #10


Specify log: {=suggested | filename | AUTO | CANCEL}

根据上面提示的内容，注意到 ‘change 669109 ’ 和 ‘sequence #10’
从网上看到一条语句，可以查出redo logs ，注意要用sys：
SQL> conn sys/oracle as sysdba                        
Connected.
SQL> select v1.group#, member, sequence#, first_change#
  2  from v$log v1, v$logfile v2
  3  where v1.group# = v2.group#;

从结果里根据 sequence# 和 first_change# 找到了要用到的log file name:
/u01/app/oracle/oradata/orcl/redo03.log

在 Specify log: {=suggested | filename | AUTO | CANCEL} 下面输入：
/u01/app/oracle/oradata/orcl/redo03.log
提示：
Log applied.
Media recovery complete.

接着：
SQL> alter database open resetlogs;

Database altered.

这样，就吧问题解决了。
