解决方案
1:调整表空间的大小
 //300w
 alter database datafile 'D:DEVORACLEDATATESTUNDOTBS05.DBF' resize 1000M;//解决方案ok


2:重新创undo表空间并切换为当前undo表空间
select tablespace_name from dba_tablespaces;
select file_name from dba_data_files; 
create undo tablespace undotbs6 datafile 'D:DEVORACLEDATATESTUNDOTBS06.DBF' size 2000m;
alter system set undo_tablespace=UNDOTBS6

原本想创建一个大的表空间替换现有的表空间,,报错
