1. 查詢表空間剩余字節(jié)大小
   SELECT TABLESPACE_NAME, SUM(BYTES)/1024/1024 AS "FREE SPACE(M)"
   FROM DBA_FREE_SPACE
   WHERE TABLESPACE_NAME = '&tablespace_name'
   GROUP BY TABLESPACE_NAME;
   注：如果是臨時表空間，請查詢DBA_TEMP_FREE_SPACE
   SELECT TABLESPACE_NAME, FREE_SPACE/1024/1024 AS "FREE SPACE(M)"
   FROM DBA_TEMP_FREE_SPACE
   WHERE TABLESPACE_NAME = '&tablespace_name';

2. 查詢表空間所有數(shù)據(jù)文件路徑
   SELECT TABLESPACE_NAME, FILE_ID, FILE_NAME, BYTES/1024/1024 AS "BYTES(M)"
   FROM DBA_DATA_FILES
   WHERE TABLESPACE_NAME = '&tablespace_name';
   注：如果是臨時表空間欢摄，請查詢DBA_TEMP_FILES
   SELECT TABLESPACE_NAME, FILE_ID, FILE_NAME, BYTES/1024/1024 AS "SPACE(M)"
   FROM DBA_TEMP_FILES
   WHERE TABLESPACE_NAME = '&tablespace_name';

3. 為空間不足的表空間增加數(shù)據(jù)文件
   ALTER TABLESPACE &tablespace_name ADD DATAFILE '&datafile_name' SIZE 2G;
   注：如果要為臨時表空間擴(kuò)容熬丧，使用下面的語句
   ALTER TABLESPACE &tablespace_name ADD TEMPFILE '&datafile_name' SIZE 2G;

4.查看臨時表空間的大小 和 數(shù)據(jù)文件路徑
SELECT TABLESPACE_NAME, FILE_ID, FILE_NAME, BYTES/1024/1024 AS "SPACE(M)"
FROM DBA_TEMP_FILES
WHERE TABLESPACE_NAME = 'TEMP';
或者
select name, bytes/1024/1024 as "大小(M)" from v$tempfile order by bytes;

5.重建并修改默認(rèn)臨時表空間辦法：
--查詢當(dāng)前數(shù)據(jù)庫默認(rèn)臨時表空間名
select * from database_properties where property_name='DEFAULT_TEMP_TABLESPACE';
--創(chuàng)建新的臨時表空間
create temporary tablespace temp02 tempfile 'E:\oracle\oradata\lims\TEMP02.DBF' size 1024M autoextend on;
--修改默認(rèn)表空間為剛剛建立的臨時表空間
alter database default temporary tablespace temp02;
--查看用戶所用臨時表空間的情況
SELECT USERNAME,TEMPORARY_TABLESPACE FROM DBA_USERS;
--刪除原來的臨時表空間
drop tablespace temp including contents and datafiles;
--查看所有表空間名確認(rèn)臨時表空間是否已刪除
select tablespace_name from dba_tablespaces;
