每天在同一时间运行sitecore计划任务

Question

我需要在每天的确切时间运行sitecore计划任务.目前,任务按以下方式安排:

Schedule: 20100201T235900|20200201T235900|127|23:59:59
Last run: 2011 06 22 01:32:25

该任务大约需要5分钟才能执行,因此"上次运行"会逐渐滑落并在稍后和之后运行.

我的主要想法是创建一个调用Web服务的Windows计划任务,并重置相关任务的上次运行时间.

还有另外一种方法吗？我错过了一些可以实现这一目标的配置属性吗？

我为此开发了自己的解决方案.

首先,将您的任务修改为每1分钟左右运行一次.它必须经常运行.您可以让任务在您喜欢的时候执行它的功能,而不是强制任务运行一次,然后等到第二天直到再次执行该功能:

在这个例子中,我强制我的任务在凌晨03:00到凌晨04:00之间运行一次:

public void Execute(Item[] itemArray, CommandItem commandItem, ScheduleItem scheduleItem)
{
  if (!IsDue(scheduleItem))
    return;

  // DO MY STUFF!!
}

/// <summary>
/// Determines whether the specified schedule item is due to run.
/// </summary>
/// <remarks>
/// The scheduled item will only run between defined hours (usually at night) to ensure that the
/// email sending will not interfere with daily operations, and to ensure that the task is only run
/// once a day. 
/// Make sure you configure the task to run at least double so often than the time span between 
/// SendNotifyMailsAfter and SendNotifyMailsBefore
/// </remarks>
/// <param name="scheduleItem">The schedule item.</param>
/// <returns>
///     <c>true</c> if the specified schedule item is due; otherwise, <c>false</c>.
/// </returns>
private bool IsDue(ScheduleItem scheduleItem)
{
  DateTime timeBegin;
  DateTime timeEnd;

  DateTime.TryParse("03:00:00", out timeBegin);
  DateTime.TryParse("04:00:00", out timeEnd);



  return (CheckTime(DateTime.Now, timeBegin, timeEnd) && !CheckTime(scheduleItem.LastRun, timeBegin, timeEnd));
}

private bool CheckTime(DateTime time, DateTime after, DateTime before)
{
  return ((time >= after) && (time <= before));
}
