I want full control over my app. I can get it with task scheduler as well, but i have to work twice as hard.http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment19http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment19Tue, 15 May 2012 12:07:37 GMT@Ken: i was referring to task scheduler specifically, that's only on windows. on *nix there's cron, i agreehttp://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment18http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment18Mon, 14 May 2012 21:33:20 GMTOh come on, unix has console too but it's lame compared to windows cmd.exehttp://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment17http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment17Mon, 14 May 2012 19:03:27 GMT@nyt - win only? *nix has crond OS schedulers are pretty darn good. http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment16http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment16Mon, 14 May 2012 17:37:20 GMT@Daniel: If you run SQL jobs then ok.http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment15http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment15Mon, 14 May 2012 17:13:08 GMTThanks for letting me know about TopShelf guys!http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment14http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment14Mon, 14 May 2012 17:10:30 GMTIf I am alreading using SQL Server, does anyone have a reason to not use it as a scheduler? http://msdn.microsoft.com/en-us/library/ms187880http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment13http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment13Mon, 14 May 2012 16:24:38 GMTMoti...that sounds more like a people problem than a technical problem. I see the ability to manually run something as a big win in the flexibility column.http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment12http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment12Mon, 14 May 2012 15:26:05 GMT@James The sys admin thing is the main reason why i stopped using windows task scheduler and moved to quartz. My app needs something done every 72 hours? great. it is still a part of my app. Let me administer that myself (if needed, let the power user access to tasks admin page). One of the worst things that can happen in production, is that a time sensitive task runs since some idiot decided to right click and ran it. Task scheduler won't even tell you who did it.http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment11http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment11Mon, 14 May 2012 12:23:51 GMT+1 James for console + win scheduler (only on win, of course)http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment10http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment10Mon, 14 May 2012 12:11:00 GMTThere are a number of Task Scheduler wrapper libraries you could use, such as http://taskscheduler.codeplex.com/ http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment9http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment9Mon, 14 May 2012 11:44:31 GMTWindows Task Scheduler + a console application is the way to go. Simple, easy to debug and sys admins can go in and mess around with scheduling if they so desire.http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment8http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment8Mon, 14 May 2012 11:31:55 GMTI think Ayende is talking about a one-off in a project so for simple tasks, sure, learning Quartz (and Topshelf) would be overkill. But when you start getting a collection of scheduled tasks, all running on different triggers, sharing logic and data layer etc, Quartz provides a decent framework and enforces patterns via IJob. Doesn't have to impact on the main app too much (or at all) if it's in its own solution whilst referencing only the projects it depends on from the main app's solution.http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment7http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment7Mon, 14 May 2012 11:16:59 GMTTo schedule on Windows Task Scheduler need I create a simple console application to put it there?http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment6http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment6Mon, 14 May 2012 11:03:03 GMTQuartz is an overkill for such a simple task - .Net gives you timers so all you need to do is to store job status & execution time somewhere... Don't make a pig of your application by adding unnecessary external dependencies, writing the execution time to a file is easier to do than learning quartz.net or topshelf.http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment5http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment5Mon, 14 May 2012 10:53:07 GMTI agree on using the builtin scheduling features of the OS. Writing code makes it more complex and a source for bugs and problems and more code to maintain.http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment4http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment4Mon, 14 May 2012 10:39:54 GMTWe use Quartz.NET with Topshelf in production, found it to be very reliable. Add decent logging and email notifications on success/error and you can near enough "set and forget" it.http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment3http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment3Mon, 14 May 2012 10:12:16 GMTOr use a scheduling framework like Quartz.NET (http://quartznet.sourceforge.net)http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment2http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment2Mon, 14 May 2012 09:30:25 GMTWhy would you not use http://quartznet.sourceforge.net/ + topshelf http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment1http://ayende.com/155489/rotten-scheduling-don-t-roll-your-own#comment1Mon, 14 May 2012 09:18:42 GMT
