Oracle建立表空间和用户
[sql]
view plain
copy
建立表空间和用户的步骤: 用户 建立:
create user 用户名 identified
by "密码"; 授权:
grant create session
to 用户名;
grant create table to 用户名;
grant create tablespace
to 用户名;
grant create view to 用户名;
[sql]
view plain
copy
表空间 建立表空间(一般建N个存数据的表空间和一个索引空间):
create tablespace 表空间名 datafile
' 路径(要先建好路径)\***.dbf ' size *M tempfile
' 路径\***.dbf ' size *M autoextend
on default storage( initial 100K,
next 100k, );
[sql]
view plain
copy
例子:创建表空间
create tablespace DEMOSPACE datafile
'E:/oracle_tablespaces/DEMOSPACE_TBSPACE.dbf' size 1500M autoextend
on next 5M maxsize 3000M; 删除表空间
drop tablespace DEMOSPACE including contents
and datafiles
[sql]
view plain
copy
用户权限 授予用户使用表空间的权限:
alter user 用户名 quota unlimited
on 表空间; 或
alter user 用户名 quota *M
on 表空间;
完整例子:
[sql]
view plain
copy
CREATE TABLESPACE sdt DATAFILE
'F:\tablespace\demo' size 800M EXTENT MANAGEMENT
LOCAL SEGMENT
SPACE MANAGEMENT AUTO;
CREATE TABLESPACE sdt_Index DATAFILE
'F:\tablespace\demo' size 512M EXTENT MANAGEMENT
LOCAL SEGMENT
SPACE MANAGEMENT AUTO;
create user demo identified
by demo
default tablespace demo;
grant connect,resource
to demo;
grant create any sequence to demo;
grant create any table to demo;
grant delete any table to demo;
grant insert any table to demo;
grant select any table to demo;
grant unlimited tablespace
to demo;
grant execute any procedure to demo;
grant update any table to demo;
grant create any view to demo;
[sql]
view plain
copy
ip导出方式: exp demo/demo@127.0.0.1:1521/orcl file=f:/f.dmp
full=y exp demo/demo@orcl file=f:/f.dmp
full=y imp demo/demo@orcl file=f:/f.dmp
full=y
ignore=y
