    执行dml语句,以及切换日志都能成功,但是数据库重启就报错

    SQL> shutdown immediate
    Database closed.
    Database dismounted.
    ORACLE instance shut down.

    SQL>

    SQL> startup
    ORACLE instance started.

    SQL>

    SQL> conn / as sysdba
    Connected to an idle instance.
    SQL> shutdown abort

    解决方法,数据库启动到mount,将损坏的日志文件清除日志组:

    SQL> startup mount
    ORACLE instance started.

    Total System Global Area 3340451840 bytes
    Fixed Size 2232960 bytes
    Variable Size 2046823808 bytes

    Redo Buffers 16326656 bytes
    Database mounted.
    SQL>

    SQL> alter database clear logfile group 1;

    Database altered.

    SQL> alter database open;

    Database altered.

    SQL> shutdown immediate
    Database closed.
    Database dismounted.
    ORACLE instance shut down.
    SQL> startup
    ORACLE instance started.

    Total System Global Area 3340451840 bytes

    Redo Buffers 16326656 bytes
    Database mounted.
    Database opened.
    SQL>

    SQL> select member from v$logfile;

    MEMBER
    --------------------------------------------------------------------------------
    /u01/oracle/oradata/yoon/redo03.log
    /u01/oracle/oradata/yoon/redo02.log
    /u01/oracle/oradata/yoon/redo01.log

    非归档模式,数据库关闭,不是正在使用的日志文件损坏,解决方法同上。
