2012年12月發過一個這樣的帖子，可是現在怎麼也找不到了。
不知為何? (好像當時還不需要註冊用戶)
現在重寫一次吧：）

做RMAN備份時，提示：
ORA-01578: ORACLE data block corrupted (file # 4, block # 642)
ORA-01110: data file 4: '/u01/app/oracle/oradata/SID/users01.dbf'

我嘗試過修復這個壞塊，但是沒有任何備份，失敗告終。
用下面的sql也查不出來，顯示no row selected. 不知為何？？
select segment_name,segment_type,extent_id,block_id, blocks
from dba_extents t
where file_id = 4
and 642 between block_id and (block_id + blocks - 1)

我也dump了那個壞塊，可是不太清除如何分析這個dump。

alter system dump datafile 4 block 642 ;

上传生成的dump 文件

不属于任何 segment的可能是游离块

对于这种快可以通过创建一张空的大的表来覆盖该块解决该问题

例如

create table tv( t1 int) tablespace xxx;

alter table tv allocate extent (datafile 4 size 9999M);
