Oracle查看用户默认表空间使用情以及手动扩展表空间sql语句

2009-11-11 16:34

查看用户默认的表空间.sql：

select username,default_tablespace from

dba_users;查看各个表空间占用磁盘情况.sql：

select

b.file_id 文件ID号,

b.tablespace_name 表空间名,

b.bytes/1024/1024||'M'字节数,

(b.bytes-sum(nvl(a.bytes,0)))/1024/1024||'M' 已使用,

sum(nvl(a.bytes,0))/1024/1024||'M' 剩余空间,

100 - sum(nvl(a.bytes,0))/(b.bytes)*100 占用百分比 from dba_free_space a,dba_data_files b

where a.file_id=b.file_id

group by b.tablespace_name,b.file_id,b.bytes

order by b.file_id

以上2者关联，就是查看用户默认表空间使用情况的sql语句：

Select *

FROM

(select username,default_tablespace from dba_users) ut,

(select

--b.file_id 文件ID号,

b.tablespace_name 表空间名,

b.bytes/1024/1024||'M'字节数,

(b.bytes-sum(nvl(a.bytes,0)))/1024/1024||'M' 已使用,

sum(nvl(a.bytes,0))/1024/1024||'M' 剩余空间,

100 - sum(nvl(a.bytes,0))/(b.bytes)*100 占用百分比 from dba_free_space a,dba_data_files b

where a.file_id=b.file_id

group by b.tablespace_name,b.file_id,b.bytes

order by b.file_id ) tsu

Where ut.default_tablespace = tsu.表空间名

orDER BY ut.username

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 users

ADD DATAFILE 'F:/peijian1/users17.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;

1.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;

2.增加数据文件

alter tablespace users add datafile

'/u01/oracle/oradata/umail/users02.dbf' size 4000M autoextend

off;

alter database datafile '/u01/oracle/oradata/umail/user01.dbf'

autoextend off;

3.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;

--------------------------------------------------------------------------------------------------

表空间不足 问题的解决　　ORA-01536: space quota

exceeded for tablespace

方法一：SQL> alter user test quota unlimited on

testtablespace;

User altered.

方法二：SQL> alter user test default tablespace

testtablespace

2 quota 0 on system

3 quota 500M on

testtablespace

4 /

User altered.

方法三：SQL> GRANT UNLIMITED TABLESPACE TO test;

Grant succeeded.
