Oracle .net提供程序的CommandTimeout未生效。

Question

我试图更改OracleCommand查询的命令超时时间，但它没有生效，因此没有触发超时异常。

• used 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：

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

      </dataSources>
    </version>
  </oracle.manageddataaccess.client>
  <connectionStrings>
    <add name="OracleDbContext" providerName="Oracle.ManagedDataAccess.Client" connectionString="User Id=xxxx;Password=xxxx;Data Source=SampleDataSource"/>
  </connectionStrings>

这个查询运行了超过10秒，但是没有触发任何异常。

Oracle .net团队解决了我的问题 :)

之前遇到过一些网络配置的问题。尝试使用Disable_Oob=on。更多信息请参阅README：http://www.oracle.com/technetwork/topics/dotnet/downloads/odpnet-managed-nuget-12102400-2718787.txt …

请您能否提供完整的解决方案？我遇到了相同的问题，在 app.config 中将 "Disable_Oob" 设置为 "on" 也没有帮助。 - 6opuc

当我们面临同样的问题时，这确实为我们解决了上述问题。我无法确定数据被丢弃的位置，但添加配置设置意味着超时按预期工作。 - thudbutt

在我的情况下，将Disable_Oob设置添加到App.config中起了作用：

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