错误：ORA-12154：TNS：无法解析指定的连接标识符

Question

每当我尝试登录或连接到SQL命令行或SQL * Plus（11g标准版Win64）时，我都会收到错误
.spinner { width: 100%; height: 50px; margin: 100px auto; animation-name: spin; animation-duration: 400ms; animation-iteration-count: infinite; animation-timing-function: linear; -ms-animation-name: spin; -ms-animation-duration: 400ms; -ms-animation-iteration-count: infinite; -ms-animation-timing-function: linear; -webkit-animation-name: spin; -webkit-animation-duration: 400ms; -webkit-animation-iteration-count: infinite; -webkit-animation-timing-function: linear; -moz-animation-name: spin; -moz-animation-duration: 400ms; -moz-animation-iteration-count: infinite; -moz-animation-timing-function: linear; } @keyframes spin { from { transform: rotate(0deg); } to { transform: rotate(360deg); } } @-ms-keyframes spin { from { -ms-transform: rotate(0deg); } to { -ms-transform: rotate(360deg); } } @-moz-keyframes spin { from { -moz-transform: rotate(0deg); } to { -moz-transform: rotate(360deg); } } @-webkit-keyframes spin { from { -webkit-transform: rotate(0deg); } to { -webkit-transform: rotate(360deg); } }
我试图用谷歌帮助解决这个问题，但我不能 所以请帮助我摆脱这个！

Answer 1

您正在尝试连接到数据库v。＆＃34; v＆＃34;是连接标识符。但是，您的Oracle客户端不知道v。这是错误消息试图告诉您的内容。

尝试

c:>tnsping v

希望这会给你这样的东西：

C:\Users\rwe>tnsping v

Used parameter files:

TNS-03505: Failed to resolve name

您可以从中提取的是位置：

C:\app\rwe\product\11.2.0\dbhome_1\network\admin\

这是您的tnsnames.ora文件所在的位置。编辑此文件并为数据库添加正确的信息v。替换Oracle数据库所在机器的服务器名称。

V =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = tcp)(HOST = servername)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = V)
    )
  )
