How to use cron misfire-instruction FireOnceNow with AdoJobStore in Quartz.NET 2.0?

问题

I am using a cron trigger with misfire-instruction set to FireOnceNow in quartz.net-2.0 set up with AdoJobStore and using XMLSchedulingDataProcessorPlugin.

cron-expression is set so the job will trigger every 1 minute: 0 0/1 * * * ?.

The job scheduler is set to start in Global.asax.cs.

Expected behaviour: If the server is stopped when a job should trigger but it is restarted before the next trigger then it should trigger once immediately.

Example:

First job triggers at 00:01:00.

I stop the server before 00:02:00 can trigger but start it a few seconds after it should, let's say 00:02:10.

When I restart the server (at 00:02:10) I would expect for the job that misfired at 00:02:00 would fire once and then normal trigger behavior would continue.

What really happens is that nothing triggers. It just continues triggering from 00:03:00.

Any ideas what I have to do to make it work as expected?

Thanks for your help!

@Global.asax.cs:

private IScheduler scheduler;

protected void Application_Start(object sender, EventArgs e)
{
    var factory = new StdSchedulerFactory();
    scheduler = factory.GetScheduler();
    scheduler.Start();
}

using Quartz;

namespace BO

    public class TestJob : IJob

        public void Execute(IJobExecutionContext context)

    }
}

回答1:

The problem was that the trigger data required for misfire action to work properly was overridden on each automatic processing of quartz_jobs.xml.

So setting overwrite-existing-data to false was required for the trigger to work after misfire:

<processing-directives>
  <overwrite-existing-data>false</overwrite-existing-data>
  <ignore-duplicates>true</ignore-duplicates>
</processing-directives>
