ORACLE 9i连接SYBASE的透明网关的配置

核心提示：7.配置oracle server的tnsnames.ora使其能够访问sybaseconnect_descriptor=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST= host_name)(PORT= port_number))(CONNECT_DATA=(SID= gatewa

7.配置oracle server的tnsnames.ora使其能够访问sybase

connect_descriptor=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST= host_name)
(PORT= port_number)
)
(CONNECT_DATA=
(SID= gateway_sid))
(HS=OK))

connect_descriptor是连接串，任取，一般为sybs

host_name：oracle server的name

port_number：oracle监听端口

gateway_sid就是3选择的sid字符串

例子如下：

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

sybs=
(DESCRIPTION=
(ADDRESS_LIST =
(ADDRESS=(PROTOCOL=TCP)(HOST= dw-server1)(PORT= 1521))
)
(CONNECT_DATA=
(SID= tg4sybs)
)
(HS=OK)
)

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

8.建立database link

如：

CREATE　DATABASE LINK sybs　CONNECT TO sa
IDENTIFIED BY prient　
USING "SBYS" ；

即可访问sybase 数据库。

需要注意的是，sybase数据库的表名，字段名，如果是小写的，那么在oracle里访问的时候要加上双引号""

如：

SQL〉select "a" from "b"@sybs;
