多数是回滚段中坏块造成的,你可以试试下面的办法
1、将数据关闭
> svrmgrl >Shutdown abort
>
> 2、修改初始化参数文件
> $ vi $Oracle_HOME/dbs/init< sid >.ora
> 添加以下参数
> rollback_segments=(system)
> _corrupted_rollback_segments=(r01,r02,r03,r04)
> _allow_resetlogs_corruption=ture
>
> 3、重新装载数据库
> svrmgrl >Startup mount
>
> 4、从数据库的控制文件中将回滚段表空间rbs的数据文件离线并去掉。
>
> svrmgrl >alter database datafile
> ‘##/##/rbs01.dbf’ offline drop;
> ---- 对数据库进行恢复。
> svrmgrl >recover database using backup controlfile;
> ---- 此时屏幕上可能会出现:
>
> ORA_00280 Change #### for thread# is in sequence#
> specify log:[< RET > for suggestedAUTOfrom logsourcecancel]
> 输入 cancel(不要输入其他命令)
>
> svrmgrl >alter database open resetlogs;
>
> 5、 重建新的回滚段
>
> ---- 将旧回滚段及回滚表空间删除。
> svrmgrl >alter rollback_segment r01 offline drop;
> svrmgrl >alter rollback_segment r02 offline drop;
> svrmgrl >alter rollback_segment r03 offline drop;
> svrmgrl >alter rollback_segment r04 offline drop;
> svrmgrl >drop tablespace rbs including contents;
> ---- 重建新的回滚表空间及回滚段。
> svrmgrl >connect internal
> svrmgrl >create rollback segment ro tablespace system;
> svrmgrl >alter rollback segment ro online;
> svrmgrl >create tablespace rbs datafile
> ‘##/##/rbs01.dbf’ size ##k;
> svrmgrl >create rollback segment r01 tablespace rbs;
> svrmgrl >create rollback segment r02 tablespace rbs;
> svrmgrl >create rollback segment r03 tablespace rbs;
> svrmgrl >create rollback segment r04 tablespace rbs;
> svrmgrl >alter rollback segment r01 online;
> svrmgrl >alter rollback segment r02 online;
> svrmgrl >alter rollback segment r03 online;
> svrmgrl >alter rollback segment r04 online;
>
>
> svrmgrl >Shutdown abort
> $ vi $ORACLE_HOME/dbs/init< sid >.ora
> rollback_segments=(r01,r02,r03,r04)
> 将参数_corrupted_rollback_segment
> _allow_resetlogs_corruption=true去掉
> svrmgrl >Startup normal
