oracle expdp和impdp常用命令选项

一、expdp导出数据库

1、按用户导出

expdp scott/tiger@orcl   DIRECTORY=oracle_dmp  dumpfile=bak.dmp schemas=scott version=10.2.0.1.0;--如果10g导入11g,加上版本号

2.按数据库导出

expdp system/manager DIRECTORY=oracle_dmp DUMPFILE=full.dmp FULL=y;

3.按表名导出

expdp scott/tiger@orcl TABLES=emp,dept DIRECTORY=oracle_dmp dumpfile=bak.dmp ;

4.查看文件目录

select * from dba_directories

二、impdp导入数据库

1、先创建一个用户

create temporary tablespace EAS_D_YXDB_STANDARD_TMEP  
tempfile 'D:APPADMINISTRATORORADATAORCLEAS_D_YXDB_STANDARD_TMEP.DBF' 
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;

create tablespace EAS_D_YXDB_STANDARD  --EAS_D_EAS32_STANDARD
logging  
datafile 'D:APPADMINISTRATORORADATAORCLEAS_D_YXDB_STANDARD.DBF' 
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;  

create user yangxiang identified by abc123  
default tablespace EAS_D_YXDB_STANDARD  
temporary tablespace EAS_D_YXDB_STANDARD_TMEP;  

grant connect,resource,dba to yangxiang;

2、执行导入命令

impdp yangxiang/abc123@{主机}/orcl directory=oracle_dmp dumpfile=EAS3220150805.dmp remap_schema=EAS32:yangxiang remap_tablespace=(EAS_D_EAS32_INDEX:sx,EAS_D_EAS32_STANDARD:sx,EAS_D_YXDB_STANDARD:sx,USERS:sx) transform=oid:n

三、exp和imp的使用

EXP SYSTEM/MANAGER BUFFER=64000 FILE=C:FULL.DMP FULL=Y --完全导出
EXP SONIC/SONIC    BUFFER=64000 FILE=C:SONIC.DMP OWNER=SONIC --导出某个用户
EXP SONIC/SONIC    BUFFER=64000 FILE=C:SONIC.DMP OWNER=SONIC TABLES=(SONIC) --表导出


IMP SYSTEM/MANAGER BUFFER=64000 FILE=C:FULL.DMP FULL=Y --完全导入
IMP SONIC/SONIC    BUFFER=64000 FILE=C:SONIC.DMP FROMUSER=SONIC TOUSER=SONIC--用户之间导入
IMP SONIC/SONIC    BUFFER=64000 FILE=C:SONIC.DMP OWNER=SONIC TABLES=(SONIC) --表导入
