先确认下对象是表还是索引：

SELECT segment_name,segment_type,extent_id,block_id, blocks

from dba_extents t

where file_id = &file_id

AND &block_id between block_id and (block_id + blocks - 1) ;

索引，但是我用dbv检测不出坏块信息

SQL> SELECT segment_name,segment_type,extent_id,block_id, blocks
from dba_extents t  2 
  3  where file_id =134
AND 2435 between block_id and (block_id + blocks - 1) ;  4

检测索引真有坏快：

analyze index username.index_name validate structure;

分析完也没有坏块

SQL> analyze index bidw.JY_SALES_TARGET_AOWEI_N3 validate structure;

Index analyzed.

尝试用RMAN  BACKUP VALIDATE DATAFILE  、BACKUP VALIDATE CHECK LOGICAL DATAFILE关注一下Marked Corrupt

rman检查也没坏块信息

考虑并评估一下在业务低峰期间刷一下buffer_cache,排除一下是否是buffer_cache Block逻辑问题

ok，谢谢
