scheduler

问题 I'm running a scheduler using python apscheduler inside web.py framework. The function runserver is supposed to run everyday at 9 a.m but it is inconsistent. It runs most days but skips a day once in a while. Code: import web from apscheduler.schedulers.blocking import BlockingScheduler #Blocking Scheduler #URLs urls = ( '/startscheduler/','index', ) Nightlysched = BlockingScheduler() @Nightlysched.scheduled_job('cron', hour=9) def runserver(): print 2+2 #doing some calculations here #Main

问题 I am working on simple Spring Batch Job. When I launch job its running in infinite loop. It doesn't stop. According to my scheduler time it should run after every 10 seconds. But when job starts it doesn't stop. Its just keeps printing sysouts from reader, processor and writer respectively. I am creating job with reader, processor and writer. And I am doing all configuration by annotations. Not by xml. Here is Batch Configuration @Configuration @EnableBatchProcessing @EnableScheduling public

问题 i'm trying to run a php script using the heroku scheduler. What command should i put in after the $ in heroku. I keep getting file not found. I have transferred the file i want to run to heroku but not luck with running it with the scheduler. 回答1: The default PHP buildpack on Heroku does not currently have PHP CLI support, so you can only use it to serve web requests via Apache and not for scripts in worker dynos. However, this is possible if you are using a PHP buildpack that does have CLI

问题 I have a native multithreaded Win32 application written in C++ which has about 3 relatively busy threads and 4 to 6 threads that don't do that much. When it runs in a normal mode total CPU usage adds up to about 15% on an 8-core machine and the application finished in about 30 seconds. And when I restrict the application to only one core by setting the affinity mask to 0x01 it completes faster, in 23 seconds. I'm guessing it has something to do with the synchronization being cheaper when

问题 I am developing large dense matrix multiplication code. When I profile the code it sometimes gets about 75% of the peak flops of my four core system and other times gets about 36%. The efficiency does not change between executions of the code. It either starts at 75% and continues with that efficiency or starts at 36% and continues with that efficiency. I have traced the problem down to hyper-threading and the fact that I set the number of threads to four instead of the default eight. When I

问题 In a java web application (servlets/spring mvc), using tomcat, is it possible to run a cron job type service? e.g. every 15 minutes, purge the log database. Can you do this in a way that is container independent, or it has to be run using tomcat or some other container? Please specify if the method is guaranteed to run at a specific time or one that runs every 15 minutes, but may be reset etc. if the application recycles (that's how it is in .net if you use timers) 回答1: As documented in

问题 Before doing new stuff, i want my scheduler-Task to remove all entries from the database, the execute-function looks like that: public function execute() { $objectManager = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\CMS\Extbase\Object\ObjectManager'); $jobRepository = $objectManager->get('\TYPO3\MyExtension\Domain\Repository\JobRepository'); //clear DB $jobRepository->removeAll(); (...)//insert new entries to DB $objectManager->get('TYPO3\CMS\Extbase\Persistence

问题 I am working on making a scheduler, just like Windows Scheduler using Quartz.Net. In Windows Scheduler, there is an option to stop a task from running if it takes more than the specified time. I have to implement the same in my scheduler. But I am not able to find any extension method/setting to configure Trigger or Job accordingly. I request some inputs or suggestions for it. 回答1: You can write small code to set a custom timout running on another thread. Implement IInterruptableJob interface
