ora-12545????????????

[pingshx]

昨天用develop2000连接另一台电脑上的数据库，出现乱码，更改了注册表一切都好，可以说运行了一天，今天用develop连接出现如下错误：ora_12545:connect failed because target host or object does not exist!
今天查了相关资料，更改develop2000机上的dns,重新从主机上copy了tnsname.ora和listener.ora.还是出现了上面的错误！还有人说更改oem的一个文件*.properties
但我这里没有oem呀，我用的版本为8.1.5.0,操作系统为：win2000!这是怎么一回事呀！

你试验一下吧
编辑C:WINNT\system32\drivers\etc\hosts

Edit the file to include the IP address and the host name of the Oracle server to which you wish to connect, thus:
126.34.10.244 hostname.domainname.com hostname othernames

first verify it is networking problem or Oracle problem .
Use TNSPING To verify it .

教你一损招，把network目录下的所有tnsname.ora和listener.ora的东西都删除掉
然后从新配置net8
