TNSPING可以，但是sqlplus可以提供ORA-12154吗? [英] TNSPING OK but sqlplus gives ORA-12154?
问题描述
我在Windows服务器上运行Oracle 11，并且我登录到同一台服务器以尝试使用SQL Plus.当我尝试连接时，即使TNSPING和其他各种诊断看起来还可以，我仍然得到ORA-12154.
I have Oracle 11 running on a Windows server and I'm logged onto the same server trying to use SQL Plus. When I try to connect I get a ORA-12154 even though TNSPING and various other diagnostics look OK.
有人可以建议原因吗?以下是详细信息.
Can anyone suggest why ? Loads of detail below.
如果我使用 EZCONNECT 这样的话，我可以使用sqlplus ..
I can use sqlplus if I use EZCONNECT like this ..
sqlplus EST/EST@192.168.10.15/ORCL
...但是如果我尝试使用 TNSNAMES 这样连接...
... but if I try to connect using TNSNAMES like this ...
sqlplus EST/EST@ORCL
...我明白了...
... I get ...
ORA-12154: TNS:could not resolve the connect identifier specified

推荐答案
创建一个环境变量TNS_ADMIN，该变量指向您的tnsnames.ora文件所在的目录.然后尝试连接sqlplus.
Create an environment variable TNS_ADMIN that points to the directory where your tnsnames.ora file resides. Then try to connect with sqlplus.
如果这行得通，那么我想也许您也安装了Oracle客户端软件，并且在运行sqlplus时，它将在客户端主目录中查找tnsnames.ora文件.
If that works, then my guess is you maybe installed the Oracle client software too, and when you run sqlplus, it looks for the tnsnames.ora file in your client home.
-在Windows中添加环境变量TNS_ADMIN的说明
1.转到控制面板/系统
2.选择高级系统设置
3.选择高级"选项卡，环境变量按钮位于底部.
4.创建新变量TNS_ADMIN并提供.ora文件的存储路径.例如C:\ app \ oracle \ product \ 11.2.0 \ client_1 \ network \ admin
-- Instructions for Adding the Environment variable TNS_ADMIN in windows
1. Go to control panel / system
2. select Advanced system settings
3. Select "Advanced" tab, and the environment variable button is at the bottom.
4. create new variable TNS_ADMIN and give the path where the .ora files are stored. e.g. C:\app\oracle\product\11.2.0\client_1\network\admin
