Question

我正在使用Quartz.net 2.2作为服务安装。使用AdoJobStore将作业存储在ms sql express中。这些工作是从asp.net 4网站管理的。一切正常，正如预期的那样：服务正在运行，作业被正确存储和触发。我面临的问题是，每天早上7点之后（这是应用程序池回收的时候）我访问该网站时，它会出现此错误：

对象'/ QuartzScheduler'已断开连接或在服务器上不存在。

[RemotingException：对象'/ QuartzScheduler'已断开连接或在服务器上不存在。   System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage（IMessage reqMsg，IMessage retMsg）+9443827   System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke（MessageData＆amp; msgData，Int32 type）+345   Quartz.Simpl.IRemotableQuartzScheduler.get_SchedulerName（）+ 0   Quartz.Impl.RemoteScheduler.b__6（IRemotableQuartzScheduler x）+8   Quartz.Impl.RemoteScheduler.CallInGuard（Func`2 func）+61

在此之后，如果我去服务器，我停止/启动Quartz.net服务，那么网站就会正常启动。

每次我通过FTP上传web.config修改或其他修改的文件导致网站重新启动时都会发生同样的事情。在这里，我获得了相同的错误，我可以绕过停止并重新启动Quartz.net服务。

以下是该网站的 global.asax ：

public static ISchedulerFactory SchedulerFactory;
public static IScheduler Scheduler;

void Application_Start(object sender, EventArgs e)
{
    NameValueCollection p = new NameValueCollection();
    p["quartz.scheduler.instanceName"] = "MyScheduler";
    p["quartz.scheduler.proxy"] = "true";
    p["quartz.threadPool.threadCount"] = "0";
    p["quartz.scheduler.proxy.address"] = "tcp://localhost:555/QuartzScheduler";

    SchedulerFactory = new StdSchedulerFactory(p);
    Scheduler = SchedulerFactory.GetScheduler(); // <-- The exception seems to occur here

    if (!Scheduler.IsStarted)
        Scheduler.Start();
}

void Application_End(object sender, EventArgs e)
{
    Scheduler.Shutdown(true);
}

Answer 1

由于没有关于此事的答案，我发布了我所做的事情：
从Scheduler.Shutdown(true);删除void Application_End可解决应用程序回收后发生的问题如果其他人有更好的答案和解释，我会将其标记为答案。

Answer 2

我的设置与您大致相同：

服务：Quartz主机
MVC网络应用程序：Quartz客户端

但是，我从未遇到过这个错误。以下是我的代码的关键部分，我希望它有所帮助：

客户参数

NameValueCollection properties = new NameValueCollection();
properties["quartz.scheduler.instanceName"] = config.QuartzInstanceName;
properties["quartz.scheduler.instanceId"] = "AUTO";
properties["quartz.scheduler.proxy"] = "true";
properties["quartz.scheduler.proxy.address"] = "tcp://127.0.0.1:" + config.QuartzPort + "/" + config.QuartzInstanceName;

主机参数

NameValueCollection properties = new NameValueCollection();
properties["quartz.scheduler.instanceName"] = config.QuartzInstanceName;
properties["quartz.scheduler.instanceId"] = "AUTO";
properties["quartz.scheduler.exporter.type"] = "Quartz.Simpl.RemotingSchedulerExporter, Quartz";
properties["quartz.scheduler.exporter.port"] = config.QuartzPort;
properties["quartz.scheduler.exporter.bindName"] = config.QuartzInstanceName;
properties["quartz.scheduler.exporter.channelType"] = "tcp";
properties["quartz.scheduler.exporter.channelName"] = "httpQuartz";
properties["jobStore.type"] = "Quartz.Simpl.RAMJobStore, Quartz";

客户端初始化

// Note, this runs in an async loop, which keeps on trying to connect until it succeeds
// This is actually kinda ugly, needs to be refactored, but it works

while (mScheduler == null)
{
  try
  {
    StdSchedulerFactory schedulerFactory = new StdSchedulerFactory(schedulerFactoryProps);
    mScheduler = schedulerFactory.GetScheduler()
    // Note that I do not use .Start() here
  }
  catch (Exception ex)
  {
  }

  if (mScheduler == null)
    Thread.Sleep(SCHEDULER_RETRY_DELAY);
}

主机初始化

StdSchedulerFactory schedulerFactory = new StdSchedulerFactory(schedulerFactoryProps);
mScheduler = schedulerFactory.GetScheduler();
mScheduler.Start();

Quartz.net服务，Scheduler已断开连接或在服务器上不存在
