Oracle数据库导入导出

一、准备工作

创建表空间：

create temporary tablespace yangwen_temp 

tempfile 'D:\oracle\oradata\orcl\yangwen_temp.dbf' 

size 50m  

autoextend on  

next 50m maxsize 20480m  

extent management local;

create tablespace yangwen_data  

logging  

datafile 'D:\oracle\oradata\orcl\yangwen_data.dbf' 

size 50m  

autoextend on  

next 50m maxsize 20480m  

extent management local;

--创建用户

create user admin123 identified by 123456  

default tablespace yangwen_data  

temporary tablespace yangwen_temp;

-- 授权限
grant connect,resource,dba to admin123;

二、导入导出方法

方案一：

1.1 数据库的备份-逻辑备份： 

expdp wzzjxt/wzzjxt@wzzj DIRECTORY=data_dump_dir dumpfile=%backup_file%.dmp 

1.2 数据库的还原-逻辑还原:

impdp aaa/aaa directory=data_dump_dir dumpfile=px.DMP REMAP_SCHEMA=px:aaa 

示例:

创建用户以及授权限

create directory DATA_PUMP_DIR as'd:\';

create user v106 identified by v106;

grant dba,connect,resource to v106;

grant read,write on directory DATA_PUMP_DIR to v106;

impdp sanyuechu/sanyuechu DIRECTORY=DATA_PUMP_DIR DUMPFILE=TEST.DMP

方案二：

1.1 数据库的备份-逻辑备份：

exp userName/passWord@IP file=d:/数据库文件.dmp

数据库的还原-逻辑还原:

创建用户：（在sys系统用户执行sql）

create user userName identified by passWord;

grant dba,connect,resource to userName;

imp userName/passWord@ORCL file=E:\数据库文件.dmp ignore=y full=y  log=e:\app\log\imp.log
