oracle Listener.ora 的参数写法问题

Question

listener.ora 两种写法

[第一种]
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST=172.16.1.1)(PORT=1521))
)
)

)

【第二种】
LISTENER =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST=172.16.1.1)(PORT=1521))
)
)

这两种写法是不是在效果上一样的。有没有什么参考文件能够看到详细的配置，我在oracle 联机文档中没有查到~

[quote]问题补充：
那还可以这样写不？？？
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST=172.16.1.1)(PORT=1521))
（ADRESS = (PROTOCOL = TCP)(HOST=172.16.1.2)(PORT=1521))
) [/quote]
可以。如：
net_service_name=
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST=sales1-svr)(PORT=1521))
(ADDRESS=(PROTOCOL=tcp)(HOST=sales2-svr)(PORT=1521)))
(ADDRESS_LIST=
(FAILOVER=on)
(ADDRESS=(PROTOCOL=tcp)(HOST=sales1-svr)(PORT=1521))
(ADDRESS=(PROTOCOL=tcp)(HOST=sales2-svr)(PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=sales.us.acme.com)))
