1：创建临时表空间
create temporary tablespace EMMS_TEMP
tempfile 'C:appadministratororadataorclEMMS_TEMP.dbf' 
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;  
 
2：创建数据表空间
create tablespace EMMS
logging  
datafile 'C:appadministratororadataorclEMMS_DATA.dbf' 
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;  
 
第3步：创建用户并指定表空间
create user EMMS dentified by EMMS123
default tablespace EMMS
temporary tablespace EMMS_TEMP;  
 
第4步：给用户授予权限
grant connect,resource,dba to EMMS;
