网上查询了一下信息  有咨询了一下开发部门 应该是开发部门提交一个request 引起的，解决办法如下

1.查詢現在的表的 maxextents

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

select owner,segment_name,segment_type,tablespace_name,extents,max_extents

 from dba_segments

 where segment_name='SYS_LOB0001182584C00040$$';

2.查詢出引起錯誤的表和字段

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

select owner,table_name,column_name,segment_name

from dba_lobs

where segment_name = 'SYS_LOB0001182584C00040$$';

3. 將maxextents 加大

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

alter table APPLSYS.WF_NOTIFICATION_OUT modify lob (USER_DATA.TEXT_LOB) (storage (maxextents 2048));

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

修改之后 OK
