一、环境：
１、linux主机ocm（192.168.217.130）作为数据库
sys@OCM> select * from v$version;
BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
２、linux主机ocp（192.168.217.133）作为独立远程监听
sys@OCP> select * from v$version;
BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
3、windows主机（192.168.217.2）作为客户端
windows 7
二、在ocm主机（192.168.217.130）上操作：
１、配tnsnames.ora
LISTENER_OCP =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.217.133)(PORT = 1521))
)
２、配参数
sys@OCM> alter system set remote_listener=LISTENER_OCP;
３、查监听
[oracle@ocm ~]$ lsnrctl status

三、在ocp主机（192.168.217.133）上操作：
１、查监听
[oracle@ocp ~]$ lsnrctl status
LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 29-MAY-2013 20:49:22
Copyright (c) 1991, 2011, Oracle. All rights reserved.

The command completed successfully
２、配tnsnames.ora
remote_130 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.217.133)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ocm)
)
)
３.连接测试
[oracle@ocm admin]$ sqlplus hr/hr@remote_130

４、解决方法：（192.168.217.133）主机上一定要配一下
vi /etc/hosts
192.168.217.130 ocm
192.168.217.133 ocp
