#可以直接修改tnsnames.ora文件如下。
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.1.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
RAC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac2-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = RAC.WORLD)
LISTENERS_RAC =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac2-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521))
#如果用scan-IP，就把scan ip的地址当成主机地址就可。
RAC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = SCAN-IP)(PORT = 1521))
(CONNECT_DATA =(SERVER = DEDICATED) (SERVICE_NAME = RAC.WORLD)
#也可以直接连接到某一个Instance，需要指明Instance Name，或者是SID
RAC2 =
(DESCRIPTION =

(INSTANCE_NAME = RAC2)
