    在trace文件中file#=3的数据文件，出现问题；而在11g数据库file#=3的是undo tablespace的数据文件，判断undo tablespace出现了问题，故采用重建undo tablespace的方法来解决

2、创建新的undo tablespace

  1）修改undo的管理为manual

SYS@ENMO1> create pfile from spfile;
File created.

通过pfile文件修改参数（spfile在nomount或mount下修改）
SYS@ENMO1> show parameter undo
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
undo_management                      string      MANUAL
undo_retention                       integer     900
undo_tablespace                      string

  2）创建新的undo tablespace

SYS@ENMO1> create undo tablespace undotbs2

  2  datafile '/u01/app/oracle/oradata/ENMO1/undotbs2.dbf' size 100m 

  3  autoextend on maxsize 2g;

Tablespace created.

  3）修改undo管理为auto

SYS@ENMO1> show parameter undo

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

undo_management                      string      MANUAL

undo_retention                       integer     900

undo_tablespace                      string

SYS@ENMO1> alter system set undo_management=auto scope=spfile;

System altered.

SYS@ENMO1> alter system set undo_tablespace=undotbs2 scope=spfile;

System altered.

  4）删除原有的undo tablespace

SYS@ENMO1> drop tablespace undotbs1 including contents and datafiles;

Tablespace dropped.
