oracle表空间的创建及dmp 文件的导入(推荐)

-- 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 ]
