DROP TABLESPACE data01 INCLUDING CONTENTS AND DATAFILES;
六、扩展表空间
首先查看表空间的名字和所属文件
select tablespace_name, file_id, file_name,
round(bytes/(1024*1024),0) total_space
from dba_data_files
order by tablespace_name;
1.增加数据文件
ALTER TABLESPACE game
ADD DATAFILE '/oracle/oradata/db/GAME02.dbf' SIZE 1000M;
2.手动增加数据文件尺寸
ALTER DATABASE DATAFILE '/oracle/oradata/db/GAME.dbf'
RESIZE 4000M;
3.设定数据文件自动扩展
ALTER DATABASE DATAFILE '/oracle/oradata/db/GAME.dbf
AUTOEXTEND ON NEXT 100M
MAXSIZE 10000M;
4、关掉数据文件自动扩展
alter database datafile '/oadata/ora9i/OATEST01.dbf' autoextend off;
设定后查看表空间信息
SELECT A.TABLESPACE_NAME,A.BYTES TOTAL,B.BYTES USED, C.BYTES FREE,
(B.BYTES*100)/A.BYTES "% USED",(C.BYTES*100)/A.BYTES "% FREE"
FROM SYS.SM$TS_AVAIL A,SYS.SM$TS_USED B,SYS.SM$TS_FREE C
WHERE A.TABLESPACE_NAME=B.TABLESPACE_NAME AND A.TABLESPACE_NAME=C.TABLESPACE_NAME;
