ORA-12154: TNS: 无法解析指定的连接标识符和 ORA-06413: 连接未打开

Question

我已经安装了 64 位的 windows 2008 操作系统和 oracle 10g 数据库和 Visual Studio 2015。

无法连接 oracle 数据库 10g。

以及现有的开发应用程序，该应用程序是使用 Visual Studio 2010 开发的，该应用程序在带有 oracle 10g 数据库的 windows xp 上运行。

请帮帮我。

Answer 1

Can you try the below

1. Include Oracle.ManagedDataAccess.dll in your solution.
2. In web.config, Under Configuration and connectionstrings, include the below

    <oracle.manageddataaccess.client>
        <version number="*">
          <dataSources>
            <dataSource alias="UATDB" descriptor="(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = ORACLEDBIP)(PORT = PORT))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = ORACLE)))"/>
        </dataSources>
        </version>
      </oracle.manageddataaccess.client>

        <connectionStrings>
        <add name="UATCONNECTIONSTRING" connectionString="Data Source=UATDB;User Id=username;Password=password;Min Pool Size=10; Connection Lifetime=300;Connection Timeout=300;Incr Pool Size=5;Decr Pool Size=2;" providerName="Oracle.DataAccess.Client"/>  
      </connectionStrings>


3. Refer the dll in your application

    using Oracle.ManagedDataAccess;

    using (OracleConnection oraConn = new OracleConnection(strOracleConn))
    {
        oraConn.Open();
        OracleCommand oraCommand = new OracleCommand();
        oraCommand.CommandType = System.Data.CommandType.StoredProcedure;
        oraCommand.CommandText = "sp name";
        oraCommand.Connection = oraConn;
    }
