超时过期。操作完成之前的超时时间或服务器没有响应。声明已终止

我的网站有很多用户(每天2万到6万)，这是一个移动文件下载网站。我可以远程访问我的服务器(windows server 2008-R2)。我以前收到过“服务器不可用”错误，但我现在看到一个连接超时错误。我不熟悉这个——为什么会发生这种情况，我该如何解决它?

完整的误差如下:

Server Error in '/' Application. Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. The statement has been terminated.

回答后编辑: my Application_Start在全局。Asax是这样的:

protected void Application_Start(object sender, EventArgs e)
{
    Application["OnlineUsers"] = 0;

    OnlineUsers.Update_SessionEnd_And_Online(
        DateTime.Now,
        false);

    AddTask("DoStuff", 10);
}

被调用的存储过程是:

ALTER Procedure [dbo].[sp_OnlineUsers_Update_SessionEnd_And_Online]
    @Session_End datetime,
    @Online bit
As
Begin
    Update OnlineUsers
    SET
        [Session_End] = @Session_End,
        [Online] = @Online

End

我有两种获取在线用户的方法:

using Application["OnlineUsers"] = 0; 另一个使用数据库

因此，对于方法#2，我重置所有在线用户在Application_Start。该表中有超过482,751条记录。

我们最近升级到NuGet版本的SqlClient (Microsoft.Data.SqlClient)，其中包含一个错误。此错误是在1的生命周期中引入的。X周期，已经固定。该修复将在2.0.0版本中可用，但在撰写本文时还不可用。可以预览一下。

其他回答

此外，您还需要检查单个记录是否没有在逻辑中得到更新，因为在该位置使用更新触发器也会导致超时错误。

因此，解决方案是确保在循环/游标之后执行批量更新，而不是在循环中一次执行一条记录。

我有这个问题，但当我离开ADO后，它就消失了。Net到Dapper为我的查询。

如果您正在使用ASP。使用Startup.cs约定，你可以像这样访问和设置查询命令超时选项:

public void ConfigureServices(IServiceCollection services)
{
    services.AddDbContextPool<MyDbContext>(_ =>
    {
        _.UseSqlServer(Configuration.GetConnectionString("MyConnectionString"), options => 
        {
            options.CommandTimeout(180); // 3 minutes
        });
    });
}

在你运行存储过程的代码中，你应该有这样的东西:

SqlCommand c = new SqlCommand(...)
//...

添加这样一行代码:

c.CommandTimeout = 0;

这将等待操作完成所需的时间。

您必须设置CommandTimeout属性。你可以在DbContext子类中设置CommandTimeout属性。

public partial class StudentDatabaseEntities : DbContext
{
    public StudentDatabaseEntities()
        : base("name=StudentDatabaseEntities")
    {
        this.Database.CommandTimeout = 180;
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        throw new UnintentionalCodeFirstException();
    }

    public virtual DbSet<StudentDbTable> StudentDbTables { get; set; }
}
