oracle表空间的创建及dmp 文件的导入

--用oracle系统权限的账号登陆

-- 1.创建用户

create user u_name identified by "u_password";

--2.赋予权限

grant dba, resource, connect  to u_name;  
grant create session to u_name;
grant create table to u_name;
grant create view to u_name;
grant create tablespace to u_name;
grant unlimited tablespace to u_name;
grant select any table to  u_name;
grant select any dictionary to  u_name;

--3.创建目录 dictionary

create directory directory_name  as 'D:\oracleEnv\Oracle\product\11.2.0\db\backup'; --路径可以自己指定

--4.赋予目录权限

GRANT read,write ON DIRECTORY directory_name  TO u_name;

--5.创建表空间

create tablespace table_space_name 
datafile 'D:\oracleEnv\Oracle\product\11.2.0\dbhome_1\oradata\table_space_name.DBF' 
size 2500M 
autoextend on next 500M maxsize 12000M;

--6.修改表空间配置

ALTER USER table_space_name  DEFAULT TABLESPACE u_name;

--8.查看表空间

  select tablespace_name , file_id,bytes from dba_data_files where tablespace_name='my_table_space_name';

-- 9.导入数据

-简单版　

impdp u_name/u_password@ORCL dumpfile=file_path full=y table_exists_action=replace

--常用版

impdp u_name/u_password@ip_address/space_name directory=my_director full=y dumpfile=my_dmp_file.DMP logfile=my_dmp_file.log table_exists_action=replace;

--高级版

impdp u_name/u_password@ip_address/space_name directory=my_director full=y dumpfile=my_dmp_file.DMP logfile=my_dmp_file.log 
[remap_schema=user_1:user_2] [remap_tablespace =table_space_1:table_space_2] [table_exists_action=replace]
