local_db 安装在suse
local_db的tnsname
       (DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.31.110)(PORT = 1521))
            (CONNECT_DATA =http://www.mamicode.com/(SERVER = DEDICATED)(SERVICE_NAME = ora11g)))
1.建dblink连接到remote_db
CREATE DATABASE LINK WIN7_API_LINK
CONNECT TO SCOTT IDENTIFIED BY tiger
USING ‘(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.31.10)(PORT = 1521)))
                  (CONNECT_DATA =http://www.mamicode.com/(SERVICE_NAME = orcl.oracle.com)))‘;
2.授予hr数据泵导出权限
GRANT DATAPUMP_EXP_FULL_DATABASE TO HR;
3.将remote_db的tnsname添加到local_db的tnsname
win7=(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.31.10)(PORT = 1521)))
            (CONNECT_DATA =http://www.mamicode.com/(SERVICE_NAME = orcl.oracle.com)))

remote_db 安装在win7
remote_db的tnsname
     win7 =(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.31.10)(PORT = 1521)))
              (CONNECT_DATA =http://www.mamicode.com/(SERVICE_NAME = orcl.oracle.com)))
1.建dblink连接到local_db
CREATE DATABASE LINK SUSE_API_LINK
CONNECT TO HR IDENTIFIED BY hr
USING ‘(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.31.110)(PORT = 1521))
                 (CONNECT_DATA =http://www.mamicode.com/(SERVER = DEDICATED)(SERVICE_NAME = ora11g)))‘;
2.建目录DMP_DIR
SQL> CREATE DIRECTORY DMP_DIR AS ‘E:\DUMP‘;
SQL> GRANT READ, WRITE ON DIRECTORY DMP_DIR TO scott;
3.授予scott数据泵导入权限
GRANT DATAPUMP_IMP_FULL_DATABASE TO scott;

将local_db的hr元数据导入到remote_db的DMP_DIR中
