Oracle数据库导入导出，oracle导入导出

Oracle数据库导入导出，oracle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
