[英]TNSPING OK but sqlplus gives ORA-12154?
我在 Windows 服务器上运行 Oracle 11,并且我登录到同一台服务器上尝试使用 SQL Plus。 当我尝试连接时,即使 TNSPING 和其他各种诊断看起来正常,我也会收到 ORA-12154。
谁能建议为什么? 下面详细介绍。
如果我像这样使用EZCONNECT,我可以使用 sqlplus ..
sqlplus EST/EST@192.168.10.15/ORCL
...但是如果我尝试像这样使用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

创建一个指向 tnsnames.ora 文件所在目录的环境变量 TNS_ADMIN。 然后尝试用sqlplus连接。
如果可行,那么我猜您可能也安装了 Oracle 客户端软件,并且当您运行 sqlplus 时,它会在您的客户端主页中查找 tnsnames.ora 文件。
-- windows下添加环境变量TNS_ADMIN的说明
1.进入控制面板/系统
2.选择高级系统设置
3. 选择“高级”选项卡,最下方是环境变量按钮。
4. 创建新变量 TNS_ADMIN 并给出 .ora 文件的存储路径。 例如 C:\\app\\oracle\\product\\11.2.0\\client_1\\network\\admin
如果您的密码中有 at 符号 (@),Sqlplus 将给出此错误。 Sqlplus 认为您正在输入连接字符串作为参数。 更改您的密码(您可以使用 SQL Developer 执行此操作)。
道德:不要在 Oracle 密码中使用 at 符号。
tnslsnr
已启动但数据库已关闭。
检查数据库是否正在运行
ps aux | fgrep pmon
如果没有这个进程,尝试手动启动数据库
su - oracle
export ORACLE_SID=XE
sqlplus sys as sysdba
然后在 sql 控制台中
startup
确保密码中没有@ 等特殊字符。 在我的情况下确实如此。
检查下面,如果它显示无效的密码,则特殊字符是原因。
sqlplus anyword/anyword@yourServiceName
