1.创建dblink第一种方法，是在本地数据库tnsnames.ora文件中配置了要远程访问的数据库。
1.设置监听： ①[root@host02 ~]# vi /etc/hosts 添加：【IP和名字】 192.168.206.2 host02 ②vi listener.ora： LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = host02)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) ) ) ADR_BASE_LISTENER = /u01/app/oracle ③vi tnsnames.ora: ENMO= (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = host02)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = ENMO) ) ) ④查看监听状态： [oracle@host02 ~]$ lsnrctl status LSNRCTL for Linux: Version 11.2.0.4.0 - Production on 01-DEC-2016 20:37:30 Copyright (c) 1991, 2013, Oracle.

2.创建dblink第二种方法，是在本地数据库tnsnames.ora文件中没配置要远程访问的数据库。
1.设置监听： ①[root@host02 ~]# vi /etc/hosts 添加：【IP和名字】 192.168.206.2 host02 ②vi listener.ora： LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = host02)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) ) ) ADR_BASE_LISTENER = /u01/app/oracle ③vi tnsnames.ora: ENMO= (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = host02)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = ENMO) ) ) ④查看监听状态： [oracle@host02 ~]$ lsnrctl status LSNRCTL for Linux: Version 11.2.0.4.0 - Production on 01-DEC-2016 20:37:30 Copyright (c) 1991, 2013, Oracle.

3.创建公共的dblink
语法：create public database link emp using 。。。
