SQL> create or replace directory dir_dpdump as '/u02/backup';

--创建DBLINK

SQL> create database link connect to u_test identified by "xxx" using 'db_esuite';

SQL> select count(*) from tab@;

--利用IMPDP导入数据

$ impdp 'u_test/"xxx"' SCHEMAS=(u_test) directory=dir_dpdump network_link="" logfile=impdp.log

$ impdp 'u_test/"xxx"' TABLES=LOG_RECORD_DETAIL_20090422 directory=dir_dpdump network_link=""
