GetNextFireTimeUtc() returns null while trigger takes place in the futre

由 て烟熏妆下的殇ゞ 提交于 2019-12-08 00:59:39
问题 I am trying to delete all the triggers that have expired because Quartz.NET crashes when it faces triggers that will never be fired. So I would like to know the next fire time of my triggers and if they do not have any, then they are expired and should be removed. But now I am seeing that even a trigger that is in the future returns a null for its next fire time: string expression = "0 26 13 17 10 ? 2015"; DateTimeOffset? nextFireTimeUtc = TriggerBuilder.Create().WithCronSchedule(expression)

nodejs job server (multiple purpose)

由 流过昼夜 提交于 2019-12-07 14:33:46
问题 I'm fairly new and just getting to know node.js (background as PHP developer). I've seen some nodeJs examples and the video on nodejs website. Currently I'm running a video site and in the background a lot of tasks have to be executed. Currently this is done by cronjobs that call php scripts. The downsite of this approach is when an other process is started when the previous is still working you get a high load on the servers etc. The jobs that needs to be done on the server are the following

Submit job with python code (mpi4py) on HPC cluster

由 ↘锁芯ラ 提交于 2019-12-07 10:51:53
问题 I am working a python code with MPI (mpi4py) and I want to implement my code across many nodes (each node has 16 processors) in a queue in a HPC cluster. My code is structured as below: from mpi4py import MPI comm = MPI.COMM_WORLD size = comm.Get_size() rank = comm.Get_rank() count = 0 for i in range(1, size): if rank == i: for j in range(5): res = some_function(some_argument) comm.send(res, dest=0, tag=count) I am able to run this code perfectly fine on the head node of the cluster using the

Callback to jobservice from intentservcie

由 淺唱寂寞╮ 提交于 2019-12-07 05:20:42
问题 I have a jobscheduler that triggers onStartjob of Jobservice. In onStartJob, I start an intentservice to do the work. After the work is done, I want intentservice to do a callback to jobservice so that onjobfinished can be called. How can I do a callback to JobService? 回答1: You can create BroadcastReceiver and register it in your Jobservice , in onStartJob() method, using some ACTION constant (for example ACTION_DOWNLOAD_FINISHED ). This receiver will delegate all work to onJobFinished()

when a quartz job fires, is it a new job class instance?

由 谁说我不能喝 提交于 2019-12-06 18:55:54
问题 I am very new to Quartz and I have some doubts about the jobs lifecycle. Let's suppose I have a single job configured to do some stuff. The job fires and ends its work. When it fires again is it the same instance (maybe set to sleep and awaken by the scheduler) or is it a new job instance (once the job ends it is killed and when the trigger condition is met again a new job instance is created)? I ask such question because when I debug my application (spring 3 mvc with quartz support) I see

Android JobScheduler onStartJob called multiple times

由 a 夏天 提交于 2019-12-06 17:45:23
问题 The JobScheduler calls onStartJob() multiple times, although the job finished. Everything works fine, if I schedule one single job and wait until it has finished. However, if I schedule two or more jobs with different IDs at the same time, then onStartJob() is called again after invoking jobFinished() . For example I schedule job 1 and job 2 with exactly the same parameters except the ID, then the order is: onStartJob() for job 1 and job 2 Both jobs finish, so jobFinished() is invoked for

Custom Object parameters within Jobs using Quartz-scheduler

由 ⅰ亾dé卋堺 提交于 2019-12-06 13:16:57
问题 I am testing out Quartz to schedule a job. However the job contains 3 non-serializable parameters. I have created a sample application below indicating how I am implementing the functionality. Does anyone know how I can use custom objects as parameters using Quartz? Below is the trigger which schedules the job, I have commented the area which is giving me issues. public class Trigger { public void run() throws Exception { SchedulerFactory sf = new StdSchedulerFactory(); Scheduler sched = sf
