ORA-12154: TNS:could 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 windows 64 位 2008 操作系统和 oracle 10g 数据库以及 visual studio 2015.

无法连接 oracle 数据库 10g。

和现有开发的应用程序是使用 visual studio 2010 开发的，正在 windows xp 上使用 oracle 10g 数据库。

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;
    }
