ORACLE 10G 创建和查看表空间（临时表空间）名称及空间信息

/*第1步：创建临时表空间 */
create temporary tablespace tv_temp
tempfile 'D:\orcldata\tv\temp.dbf'
size 20480M
autoextend on
next 500M maxsize 30720M
extent management local;

/*第2步：创建数据表空间 */
create tablespace tv_data
nologging
datafile 'D:\orcldata\tv\data.dbf'
size 4096M
autoextend on
next 200M maxsize 20480m
extent management local;

/*第3步：创建用户并指定表空间 */
create user tv identified by tv
default tablespace tv_data
temporary tablespace tv_temp;

/*第4步：给用户授予权限 */

grant connect,resource,dba to username;

grant create session,create table,unlimited tablespace to tv;

1、查看表空间

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%
------------------------------ ------------ ----------- ----------
KB 1024 1023 .1
SYSAUX 320 3 99.06
SYSTEM 450 9 98
TV 4096 128 96.88
UNDOTBS1 5760 5670 1.56
USERS 5 5 0

6 rows selected.

2、查看临时表空间

SQL> select tablespace_name from dba_tablespaces;

TABLESPACE_NAME
------------------------------
SYSTEM
UNDOTBS1
SYSAUX
TEMP
USERS
TV
KB

7 rows selected.

SQL> select tablespace_name,file_name,bytes/1024/1024 file_size,autoextensible from dba_temp_files;

TABLESPACE_NAME FILE_NAME FILE_SIZE AUT
---------------------------------------------------------------------------
TEMP E:\ORCLDATA\TV\TEMP01.DBF 1834 YES

3、增加表空间大小

alter tablespace tv add datafile 'E:\orcldata\tv\data1.dbf' size 4096M;

4、增加临时表空间大小

SQL> alter database tempfile 'E:\orcldata\tv\temp01.dbf' resize 8192M;

Database altered.
