一个非常简单的IMPDP事儿

EXPDP出来的DMP文件包含2个Schema的表，现在要IMPDP到一个Schema里面
试了几把都报错，好久不用逻辑导出入，折腾了好久，出现各种错误
1、创建目录并授权
create or replace directory DUMPDIR as ‘/home/oracle/dump_dir’;
grant read,write on directory DUMPDIR to test2;
2、ORDER用户的表T_ORDER_DEPOSIT_530 impdp导入TEST2用户下
impdp test2/test123 remap_schema=ORDER:TEST2 tables=ORDER.T_ORDER_DEPOSIT_530 directory=DUMPDIR dumpfile=OA188672.dmp logfile=OA188672.log
—————————————————————————————-

Failing sql is:

上面涉及两点，1、Schema变了-> remap_schema来转换,2、TABLE要指定Schema
下面将MEMBERS用户下备份的表恢复到TEST2用户下
[oracle@localhost dump_dir]$ impdp test2/test123 remap_schema=MEMBERS:TEST2 tables=MEMBERS.T_RECIEVE_PAY_TRADE_6MER0504 directory=DUMPDIR dumpfile=OA186751.dmp logfile=OA186751_MEMBERS.log

再对另外一个Schema进行IMPDP就可以了。。。

错误例子：
下面这个首先关键字就没选好，只是想把表从一个用户导入到另外一个用户，而remap_table是修改表名称
–impdp test/test123 DIRECTORY=DUMPDIR remap_table=MEMBER.T_RECIEVE_PAY_TRADE_6MER0504:TEST.T_RECIEVE_PAY_TRADE_6MER0504 dumpfile=OA186751.dmp logfile=OA186751_imp.log

remap_table、remap_tablespace多组对象转换的话，每组对象之间用逗号隔开
tables多张表时，每张表之间用逗号隔开

Remap_tablespace如果需要转换多个表空间，如A1转换成B1，A2转换成B1，有如下两种方式
remap_tablespace=A1:B1 remap_tablespace=A2:B1
remap_tablespace= A1:B1, A2:B1

Remap_table如果需要转换多个表名
同一个schema的情况下，如A1转换成B1，A2转换成B1，有如下两种方式
remap_table=A1:B1 remap_table=A2:B1
remap_table= A1:B1, A2:B1

跨schema只导出导入表并重命名的标准方式如下
expdp时tables写上schema.表名并用逗号隔开
impdp时需要remap_schema， tables可写可不写，remap_table冒号前面的表名加上schema，冒号后面的表名不加schema
expdp system/123456 tables=t01.test101,t01.test102,t01.test103 directory=DATA_PUMP_DIR dumpfile=t011.dbf
一个案例
A服务器导出用户ESB的一张分区表ESB_LOG
expdp system/123456 directory=DATA_PUMP_DIR dumpfile=ESB_LOG.dmp logfile=ESB_LOG.log tables=ESB.ESB_LOG
导入到B服务器的part用户，表名改为ESB_LOG2(加了tables=ESB.ESB_LOG，其实加不加无所谓，反正ESB_LOG.dm就是只有一张表ESB.ESB_LOG)
impdp system/123456 directory=DATA_PUMP_DIR dumpfile=ESB_LOG.dmp logfile=ESB_LOG2.log tables=ESB.ESB_LOGremap_schema=ESB:part remap_tablespace=ESB07:part,ESB08:part,ESB09:part,ESB10:part,ESB11:part,ESB12:part,ESB:part remap_table=ESB.ESB_LOG:ESB_LOG2
