--创建dump目录
create or replace directory mydump as 'E:\oracle\dump';
--给用户赋予导入、导出权限
grant read,write on directory DATA_PUMP_DIR to bpm3_in;

--导出命令
expdp bpm3_in/bpm@bpm schemas=bpm3q_testin dumpfile=bpm3q_testin.dmp DIRECTORY=DATA_PUMP_DIR  
expdp bpm3_in/bpm@bpm schemas=bpm3q_testout dumpfile=bpm3q_testout.dmp DIRECTORY=DATA_PUMP_DIR


--导入命令
--同用户名导入
impdp impdp/bpm DIRECTORY=DATA_PUMP_DIR DUMPFILE=bpm_2round_in.dmp SCHEMAS=bpm_2round_in
impdp impdp/bpm DIRECTORY=DATA_PUMP_DIR DUMPFILE=bpm_2round_out.dmp SCHEMAS=bpm_2round_out

--不同用户名导入
impdp bpm3_in/bpm@bpm DIRECTORY=DATA_PUMP_DIR DUMPFILE=bpm3q_testin.dmp remap_schema=bpm3q_testin:bpm_yanshi_in
impdp bpm3_in/bpm@bpm DIRECTORY=DATA_PUMP_DIR DUMPFILE=bpm3q_testout.dmp remap_schema=bpm3q_testout:bpm_yanshi_out

--高版本 向 低版本导入 要加版本号 
select * from v$version; --查询版本号,查询结果：
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Prod
PL/SQL Release 10.2.0.3.0 - Production
"CORE	10.2.0.3.0	Production"
TNS for 32-bit Windows: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production

例：expdp test1/fdsafdsa@orcl schemas=tcsdev1 dumpfile=tcs_20181127_10.dmp DIRECTORY=DATA_PUMP_DIR version=10.2.0.3.0

-- 导入时指定表空间
impdp test1/fdsafdsa@orcl DIRECTORY=DATA_PUMP_DIR DUMPFILE=tcs_20190305.dmp remap_schema=tcs:tcsdev1 remap_tablespace=tcs:users

-- 创建表空间语法
create temporary tablespace tcs_temp
tempfile 'E:\oracle\tabespace\tcs_temp.dbf'
size 50m
autoextend on
next 50m maxsize 20480m
extent management local;
-- 创建数据表空间的例子如下：
create tablespace tcs_data
logging
datafile 'E:\oracle\tabespace\tcs_data.dbf'
size 50m
autoextend on
next 50m maxsize 20480m
extent management local;
