Oracle数据库导入导出

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
