我正在尝试更改 OracleCommand 查询的命令超时，但它不起作用，因此不会触发超时异常。

  • 使用 Oracle.ManagedDataAccess.dll (4.121.2.0)

    using (OracleConnection _connection = new OracleConnection(connectionString))
{

    using(OracleCommand command = _connection.CreateCommand())
    {

      command.CommandText = commandText;
      command.CommandTimeout = 10;

     _connection.Open();
      using(OracleDataReader reader = command.ExecuteReader())
      {
          while (reader.Read())
          {
                Console.WriteLine(reader.GetValue(0));
          }
       }
    } }

配置：

<configSections>
    <section name="entityFramework"
      type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"

        <bindingRedirect oldVersion="4.121.0.0 - 4.65535.65535.65535" newVersion="4.121.2.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
  <oracle.manageddataaccess.client>
    <version number="*">
      <dataSources>
        <dataSource alias="SampleDataSource" descriptor="(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=xxx)(PORT=1561))(CONNECT_DATA=(SERVICE_NAME=xxxx))) "/>
      </dataSources>
    </version>
  </oracle.manageddataaccess.client>
  <connectionStrings>
    <add name="OracleDbContext" providerName="Oracle.ManagedDataAccess.Client" connectionString="User Id=xxxx;Password=xxxx;Data Source=SampleDataSource"/>
  </connectionStrings>

此查询运行超过 10 秒，但未引发异常。

将设置 Disable_Oob 添加到 App.config 对我有用：

...
<oracle.manageddataaccess.client>
     <version number="*">
       <settings>
         <setting name="Disable_Oob" value="on" />
       </settings>
       <dataSources> 
    ...

Oracle .net 团队解决了我的问题 :)

之前通过一些网络配置看到过这个问题。尝试使用 Disable_Oob=on。README 中的更多信息：http ://www.oracle.com/technetwork/topics/dotnet/downloads/odpnet-managed-nuget-12102400-2718787.txt ...</p>
