定位坏块

sqlplus / as sysdba --登陆

--查询

select owner,

        file_id,

        segment_name,

        segment_type,

        block_id,

        blocks　

from dba_extents　　

where file_id = 2 and 

block_id <= 1724 and (block_id + blocks - 1) >= 1724;

可以看到是undo表空间损坏，重建undo

1、备份数据库文件orcl_data\orcl（关闭数据库复制一份）

2、重建undo

sqlplus / as sysdba

----设置undo管理方式为 ’手动‘

SQL> alter system set undo_management = manual scope=spfile;

SQL> alter system set undo_tablespace='' scope=spfile;

SQL>shutdown immediate

SQL>startup

SQL>create undo tablespace undotbs2 datafile 'E:\orcl_data\orcl\undotbs2.dbf' size 100M;

----设置undo管理方式为 ’自动‘

SQL> alter system set undo_management =auto scope=spfile;

----设置undotbs 为新建的undotbs2

SQL> alter system set undo_tablespace = undotbs2 scope=spfile;

----删除原来损坏的undo表空间

SQL> drop tablespace UNDOTBS1 including contents and datafiles;

SQL>shutdown immediate

SQL>startup
