解決方案
1:調整表空間的大小
 //300w
 alter database datafile 'D:\DEV\ORACLEDATA\TEST\UNDOTBS05.DBF' resize 1000M;//解決方案ok


2:重新創undo表空間並切換為當前undo表空間
select tablespace_name from dba_tablespaces;
select file_name from dba_data_files; 
create undo tablespace undotbs6 datafile 'D:\DEV\ORACLEDATA\TEST\UNDOTBS06.DBF' size 2000m;
alter system set undo_tablespace=UNDOTBS6

原本想創建一個大的表空間替換現有的表空間,,報錯
