查看当前日志组信息:
SQL> select * From v$log;

    GROUP#    THREAD#  SEQUENCE#      BYTES    MEMBERS ARC STATUS
---------- ---------- ---------- ---------- ---------- --- ----------------
FIRST_CHANGE# FIRST_TIM
------------- ---------
        1          1        334  52428800          1 NO  ACTIVE
      3613897 27-SEP-13

        4          1        333  104857600          1 NO  INACTIVE
      3613895 27-SEP-13

        3          1        336  52428800          1 NO  CURRENT
      3613948 27-SEP-13

        2          1        335  52428800          1 NO  ACTIVE
      3613899 27-SEP-13

如果查询v$log发现损坏的online redo log是inactive, 说明该组日志是非当前日志, 而且已经归档完成 ( STATUS 是INACTIVE , ARCHIVE 是YES ) .

处理方法(适用于归档及非归档数据库) :

使用clear 命令清理这个文件所在的redo log group .

SQL> alter database clear logfile group 3 ;

如果该日志组还没有归档 (STATUS 是INACTIVE , ARCHIVE 是 NO )

那么需要使用如下命令

SQL> alter database clear unarchived logfile group 3 ;

然后打开数据库 , 备份 .
