關於oracle的表空間（Oracle創建用戶+創建表空間+指定用戶使用表空間+修改表空間大小）

前提：oracle目錄：/home/oracle/oradata/orcl

/*創建臨時表空間TEST_tmp  */  

create temporary tablespace TEST_tmp  

tempfile '/home/oracle/oradata/orcl/TEST_tmp.DBF' 
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;  

/*創建數據表空間TEST.DBF  */

create tablespace TEST  
logging  
datafile '/home/oracle/oradata/orcl/TEST.DBF' 
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;  

/*創建用戶並指定表空間  */
create user UserName identified by Password  
default tablespace TEST  
temporary tablespace TEST_tmp;  
alter user UserName temporary tablespace TEST_tmp;

/*給用戶授予權限  */
grant connect,resource,dba to UserName ;

/*修改表空間TEST.DBF大小*，提示：修改表空間大小不會清除或改變表中的數據/
alter database datafile '/home/oracle/oradata/orcl/TEST.DBF'resize 4029M;
