ORA-01578: ORACLE data block corrupted (file # 3, block # 1675) ORA-01110: data file

oracle出现数据坏块，

解决办法：

1、根据文件号和块号查出损坏的是对象,表还是LOB segment

select tablespace_name,segment_type,owner,segment_name from dba_extents where file_id=4 and 234413between block_id AND block_id + blocks - 1;

①、如果是对象，可以重建

alter index indexname rebuild

②、如果是表，可以使用10231事件忽略坏块，然后使用CTAS方式重建表最后rename table，别忘记rebuild index

alter session SET EVENTS '10231 trace name context forever,level 10';

create table tab_new as select * from tab;

rename tab to tab_bak;

rename tab_new to new;

alter index indexname rebuild;
alter session SET EVENTS '10231 trace name context off';
