1、查看表空間
select tv.tablespace_name "TABLESPACE_NAME",totalspace "TOTALSPACE/M",freespace "FREESPACE/M",round((1-freespace/totalspace)*100,2) "USED%"
from
(select tablespace_name,round(sum(bytes)/1024/1024) totalspace from dba_data_files group by tablespace_name) tv,
(select tablespace_name,round(sum(bytes)/1024/1024) freespace from dba_free_space group by tablespace_name) fs
where tv.tablespace_name=fs.tablespace_name;
TABLESPACE_NAME TOTALSPACE/M FREESPACE/M USED%

3、增加表空間大小
alter tablespace tv add datafile 'E:\orcldata\tv\data1.dbf' size 4096M;
4、增加臨時表空間大小
SQL> alter database tempfile 'E:\orcldata\tv\temp01.dbf' resize 8192M;
Database altered.
