Question

在创建db link时，指向远程数据库的连接字符串的配置方式有以下哪些方式

Answer 1

把Address_list 去掉试试：

create database link linkserver
connect to ssss identified by ssss
using '(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.9.206.222)(PORT = 1521))
(CONNECT_DATA = (SERVICE_NAME = orcl)
)
)

就是用Oracle的 Net Configuration Assistant 配置一个 连接到Oracle服务器的 “本地网络服务名”

配置好后，在tnsnames.ora中有一段类似

orcl =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.9.206.222)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
的内容

然后语法换成：

create database link linkserver
connect to ssss identified by ssss
using orcl
