分享有谁知道这个TNS-12545 错误?
我用ASP+IIS+ORACLE做的WEB版的MIS,WEB服务器和数据库服务器是两台不同的机器.用户访问量很大,前些天一直很正常,今天突然不行了,当打开一个页面时,提示说:TNS-12545 Connect failed because target host or object does not exist.可是我在SQLPLUS中连接时完全正常,证明数据库服务器没有问题,访问WEB服务器上其它不用连库的网页时也正常,实在找不出原因,最后无奈,只好把WEB服务器重启了,之后就正常了,可是我仍然不明白这其中的原因,哪位大侠能告诉我?

请先配置好服务名.
之后，机子没开或数据库没完全启动.

TNS-12545 Connect failed because target host or object does not exist
Cause: The address specified is not valid, or the program being connected to does not exist.
Action: Ensure the ADDRESS parameters have been entered correctly; the most likely incorrect parameter is the node name. Ensure that the executable for the server exists (perhaps "oracle" is missing). If the protocol is TCP/IP, edit the TNSNAMES.ORA file to change the host name to a numeric IP address and try again.
