Scheduledexecutorservice Not Working


jbrisbin commented Aug 27, 2014 This belongs in the HashWheelTimer itself IMO. Starting a thread won't take a second unless your machine is ridiculously overloaded, and I think the thread will get initialised up-front anyways if you use a fixed size thread pool. Docs: ScheduledExecutorService#scheduleAtFixedRate Reactor member ifesdjeen commented Aug 28, 2014 @lhazlewood I mean that they are rounded to precision. Not the answer you're looking for? http://qrwsoftware.com/not-working/working-not-working-review.html

I'm guessing it's the initialisation of your own tasks. This would be way less code, simpler than extending ScheduledThreadPoolExecutor, and it would be reusable. A few days later when I scaled down my fleet, all that was left were broken hosts that smiled and pretended to be working. #27 by Ed on July 17, 2014 The best solution I've found is to pass a custom thread factory when constructing the Executor: Executors.newSched….(…, MyThreadFactory) In addition to the thread factory being able to set an uncaught exception

Error is not an Exception so it won't be catched. #7 by Brennen on January 27, 2013 - 5:52 am Quote Great post, had troubles with this. Thats right! Try using schedule instead of scheduleAtFixedRate and the runs should execute on a more regular schedule regardless of delays. –Ted Hopp Apr 9 '14 at 6:25 I have tried Of course your factory will be used by the executor, but the uncaught exeception handler just never gets called, which makes all exceptions just disappear without notice - a debugging nightmare.

And when I started the test it indicated good numbers at first, but after having run for about 5 seconds the numbers become all screwed up. I automated my job and the company doesn't know, what do I do now? Reactor member ifesdjeen commented Aug 28, 2014 Not sure why even argue, to be honest. Already have an account?

jbrisbin referenced this issue Aug 28, 2014 Closed fix cancel bug in HashWheelTimer #371 Reactor member ifesdjeen commented Aug 28, 2014 What is resolution in that case? Since the task is executed by a thread, Does the start up time depends on the thread priority? How can I make it run at exact delay of 60 secs? The only docs for this that I'm aware of are the wiki docs here: AsyncTaskExecutor.

Not the answer you're looking for? Other rare features found on certain Blu-ray Players is support for DVD-Audio and Super-Audio-CD formats. As for the resolution, I believe the simplest solution is to (at a minimum) throw an IllegalStateException or, perhaps more meaningfully, throw some Reactor-specific (or HashedWheel) exception that reflects the condition. Will this library solve my purpose(run the job at specific time without any delay)?

For example, scheduleAtFixedRate: Creates and executes a periodic action that becomes enabled first after the given initial delay, and subsequently with the given period; that is executions will commence after initialDelay Assuming we change this to throw an IllegalArgumentException, how is the user supposed to recover from this error?

We'll see what others say. Getting "Current Sitecore database cannot be established" using Sitecore Powershell Extensions Share save files between computers Adi Shankaracharya’s Parakaya Pravesha to Learn Kamashastra was this Dharmic?

But that didn't work at all. Why didn't "spiel" get spelled with an "sh"? Docs already say that it should be rounded...

I can't see how it could if you are calling schedule() instead of scheduleAtFixedRate().

Many of the players look similar and claim to offer similar specifications and features. #24 by Eliot Stock on July 4, 2014 - 11:55 am Quote There should be more swearing

This may result in a series of bunched-up runs (one launched immediately after another) if delays prevent the timer from starting tasks on time. Can it work? Also, the TestRunner finishes by sleeping for 50ms, simulating doing some real work. We do mention in the documentation that in case you want to have a better precision, you change the configuration of the timer, get your resolution smaller and get a đź‘Ť
