TNSPING OK但sqlplus给ORA-12154？

Question

我在Windows服务器上运行了Oracle 11,并且我登录到尝试使用SQL Plus的同一服务器上.当我尝试连接时,即使TNSPING和其他各种诊断看起来没问题,我也会得到ORA-12154.

谁有人建议为什么？下面的大量详细信息.

如果我像这样使用EZCONNECT,我可以使用sqlplus ..

sqlplus EST/EST@192.168.10.15/ORCL

...但是如果我尝试使用这样的TNSNAMES进行连接......

sqlplus EST/EST@ORCL

......我明白了......

ORA-12154: TNS:could not resolve the connect identifier specified

TNSPING工作正常

而听者看起来是这样的:

Answer 1

创建一个环境变量TNS_ADMIN,指向tnsnames.ora文件所在的目录.然后尝试连接sqlplus.

如果可行,那么我猜你也可能安装了Oracle客户端软件,当你运行sqlplus时,它会在你的客户端主页中查找tnsnames.ora文件.

- 在窗口中添加环境变量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并给出存储.ora文件的路径.例如C:\ app\oracle\product\11.2.0\client_1 \network\admin

Answer 2

如果你的密码中有一个at符号(@),Sqlplus会给出这个错误.Sqlplus认为您正在输入连接字符串作为参数.更改密码(您可以使用SQL Developer执行此操作).

道德:不要在Oracle密码中使用at-signs.
