SQL Server

曾因工作的原因,在别人的督促之下,试了SQL 7同ORACLE联接,在SQL7中直接访问ORACLE的数据库方法,下面将该方法简单说一下。

当时用的是LINKED SERVER直接联接对方数据库。

一、先在SQL服务器装上ORACLE的客户端,并设置好
二、然后打开ENTERPRISE MANGER,与昨天相同的方法进到添加LINKED SERVER窗口
三、在LINKED SERVER框输入要使用的服务器名,服务器名允许按命名规则任意命名,但不能与已有的REMOTE SERVER或LINKED SERVER重名。
四、在SERVER区选中“OTHER DATA SOURCE”
五、Provider name选择“Microsoft OLE DB Provider for Oracle”
六、在Product name处输入“Oracle”
七、在Data source处输入在Oracle客户端程序中设置的服务器名
八、在Provider处输入“MSDAORA” 注:用ORACLE就是这个,不能改
九、在Server opentions区选择“RPC”和“RPC OUT”
十、再切换到安全(Security),根据实际设置。
(我都是选择“THEY WILL BE MAPPED TO”,然后输入帐号和口令)
十一、单击确定完成设置

我按这个步骤设置成功,但因时间和条件的问题,一直没再继续试其它的设置,如果各位那位有这样的条件的话,请再试一下其它的选项,看有什么不同,试完希望能将步骤和结果给我发一份。

另需说明的是,这种的联接的稳定性还是可以的,在设好以后的一年中,只因为对方服务器出问题重设了一次,还有一次是ORACLE的客户端被管理员不小心删了个文件,又重设了一次,然后一直没出问题,并且速度也还可以,一个过程,在ORACLE客户端执行需要0.1秒钟,通过LINKED SERVER执行需要0.2秒钟左右。

明天给大家写一下上面同样的设置用SQL7的系统过程设置的方法。

以上在UNIX ORACLE7和NT4 SP5 SQL7上测试成功。
