[oracle@hr1 opt]$ mkdir -p infor1

SQL> create directory scprd as '/opt/infor1';

Directory created.

SQL> grant read,write on directory scprd to system;

Grant succeeded.

[oracle@hr1 opt]$ expdp system/oracle@HR dumpfile=tablespace_hr.dmp schemas=hr2 DIRECTORY=hr LOGFILE=hr2_exp.log

[oracle@hr1 opt]$ impdp system/oracle@HR directory=hr dumpfile=tablespace_hr.dmp remap_schema=hr2:hr6, remap_tablespace=hr2_DATA:hr6_DATA logfile=hr6_imp.log

用remap实现schema和tablespace的导入。

有时候import会报错：

重复执行几次就可以了。
