Oracle 建立表空间

SYS用户在CMD下以DBA身份登陆：

在CMD中打sqlplus /nolog

然后再

conn / as sysdba

//创建临时表空间

create temporary tablespace user_temp

tempfile 'D:\oracle\oradata\Oracle9i\user_temp.dbf'

size 50m

autoextend on

next 50m maxsize 20480m

extent management local;

//创建数据表空间

create tablespace test_da<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>ta

logging

datafile 'D:\oracle\oradata\Oracle9i\user_da<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>ta.dbf'

size 50m

autoextend on

next 50m maxsize 20480m

extent management local;

//创建用户并指定表空间

create user username identified by password

default tablespace user_da<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>ta

temporary tablespace user_temp;

//给用户授予权限

grant connect,resource to username;

//以后以该用户登录，创建的任何数据库对象都属于user_temp 和user_da<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>ta表空间，

这就不用在每创建一个对象给其指定表空间了

撤权：

revoke 权限... from 用户名;

删除用户命令

drop user user_name cascade;

建立表空间

CREATE TABLESPACE da<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>ta01

DATAFILE '/oracle/oradata/db/DA<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>TA01.dbf' SIZE 500M

UNIFORM SIZE 128k; #指定区尺寸为128k,如不指定，区尺寸默认为64k

删除表空间

DROP TABLESPACE da<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>ta01 INCLUDING CONTENTS AND DATAFILES;

一、建立表空间

CREATE TABLESPACE da<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>ta01

DATAFILE '/oracle/oradata/db/DA<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>TA01.dbf' SIZE 500M

UNIFORM SIZE 128k; #指定区尺寸为128k,如不指定，区尺寸默认为64k

二、建立UNDO表空间

CREATE UNDO TABLESPACE UNDOTBS02

DATAFILE '/oracle/oradata/db/UNDOTBS02.dbf' SIZE 50M

#注意：在OPEN状态下某些时刻只能用一个UNDO表空间，如果要用新建的表空间，必须切换到该表空间:

ALTER SYSTEM SET undo_tablespace=UNDOTBS02;

三、建立临时表空间

CREATE TEMPORARY TABLESPACE temp_da<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>ta

TEMPFILE '/oracle/oradata/db/TEMP_DA<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>TA.dbf' SIZE 50M

四、改变表空间状态

1.使表空间脱机

ALTER TABLESPACE game OFFLINE;

如果是意外删除了数据文件，则必须带有RECOVER选项

ALTER TABLESPACE game OFFLINE FOR RECOVER;

2.使表空间联机

ALTER TABLESPACE game ON<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>LINE;

3.使数据文件脱机

ALTER DATABASE DATAFILE 3 OFFLINE;

4.使数据文件联机

ALTER DATABASE DATAFILE 3 ON<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>LINE;

5.使表空间只读

ALTER TABLESPACE game READ ON<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>LY;

6.使表空间可读写

ALTER TABLESPACE game READ WRITE;

五、删除表空间

DROP TABLESPACE da<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>ta01 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_da<wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr><wbr></wbr>ta_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;

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
