Oracle.ManagedDataAccess无法解析连接字符串中的别名 [英] Oracle.ManagedDataAccess not resolving alias in connection string

问题描述

尝试从新的VB.NET 4.5应用程序连接到Oracle数据库时出现以下错误

I'm getting the following error while trying to connect to an Oracle database from a new VB.NET 4.5 application

"ORA-00351:网络库:名称-值字符串的过早结尾"

"ORA-00351: Network Library: Name-Value premature end of string"

OracleConnection似乎无法解析我在连接字符串中输入的别名

It seems like OracleConnection is not resolving the alias I am putting in my connection string

Me.sCNX = "Data Source=" & sDSN & ";User ID=" & sUSER & ";Password=" & sPWD & ";Enlist=false;Pooling=False;"

sDSN是上述别名

我必须将tnsnames.ora文件放在一个自定义文件夹中，所以我试图将环境变量TNS_ADMIN添加到正确的目录中，没有太大作用

I have to put the tnsnames.ora file in a custom folder, so I tried to add the environment variable TNS_ADMIN to the right directory, didn't work much

我试图在app.config中放置一条设置行，以便像这样设置目录

I tried to put a setting line in app.config in order to set the directory like this

  <oracle.manageddataaccess.client>
    <version number="*">
      <settings>
        <setting name="TNS_ADMIN" value="E:\oracle_admin" />
      </settings>
    </version>
  </oracle.manageddataaccess.client>

也不起作用

这是我正在谈论的tnsnames.ora文件

Here is the tnsnames.ora file I am talking about

formation=
 (DESCRIPTION=
   (ADDRESS=
     (PROTOCOL=tcp)
     (HOST=*IP*)
     (PORT=*PORT*)
   )
   (CONNECT_DATA= 
    (SERVICE_NAME=*service*)
   )
 )

谢谢

推荐答案

发生我只是忘记了sqlnet.ora文件以及tnsnames.ora文件中有不需要的字符的事实，因此无法很好地对其进行解析...

Happens that I just forgot the sqlnet.ora file and the fact that there was unwanted characters in my tnsnames.ora file, so it couldn't be parsed well...
