quartz-scheduler

Is it possible using the Quartz .NET assembly to generate a cron expression? I saw that the CronScheduleBuilder class has a private member cronExpression which is essentially what I am looking for. Is there any other way to get the cron expression itself? Ian R. O'Brien Possible using ICronTrigger.CronExpressionString CronScheduleBuilder csb = CronScheduleBuilder .WeeklyOnDayAndHourAndMinute(DayOfWeek.Monday, 12, 0); ICronTrigger trigger = (ICronTrigger)TriggerBuilder .Create() .WithSchedule(csb) .Build(); string cronExpression = trigger.CronExpressionString; Thomas Using Ian answer, I have

I am new to Quartz . I did manage to figure out that default value for Scheduler configuration is org.quartz.threadPool.threadCount=-1 . But it did not find anywhere what this implies. Does this mean that there will be only one thread or has it some other 'number'? I am playing with quartz-scheduler v2.2. It depends.. If you use Spring Framework then you can see that the real default is defined in SchedulerFactoryBean : public static final int DEFAULT_THREAD_COUNT = 10; In case of using bare Quartz and and not passing any property, it will use its default configuration, which you can find it

I am having trouble trying to get Quartz.NET to work with an AdoJobStore. None of the other questions here seem to be running into the problem that I am. I was able to get it working fine without the AdoJobStore configuration but would like to persist everything in the end, however I am getting an error when trying to GetScheduler() that I can't figure out. Here's my quartz app.config section: <quartz> <add key="quartz.scheduler.instanceName" value="XxxDefaultQuartzScheduler"/> <add key="quartz.scheduler.instanceId" value="instance_one"/> <add key="quartz.threadPool.type" value="Quartz.Simpl

The documentation for JobDetail.requestsRecovery property states the following Instructs the Scheduler whether or not the Job should be re-executed if a 'recovery' or 'fail-over' situation is encountered. Now, what is a 'recovery' situation or a 'fail-over' situation? How are they different? Does the recovery happen only if the JVM crashes during job execution or does it happen if the job execution fails because of an exception also? zerologiko A " Recovery situation " is the generic term, one kind of recovery situation is the " fail-over ". A fail-over is a process used by fault-tolerance

I have one job that needs to be execute twice a day at different time . e.g. 10:00 and 15:30. How can i achieve this ? I am confuse because minute is different for both the time. For 11:00 and 15:00 its easy because for both the times, minute portion is same, but for the different minute portion is it feasible with cron ? Thanks in Advance and apologies for silly question. jjj Try following which you will get closest in one expression 0 0 10,15/12 * * ? this will run 10:00 and 15:00. You can set values for each job: 0 10 * * * job 30 15 * * * job Here is more info: * * * * * command to be

Is there a way I could run a job only once using Quartz in Java? I understand it does not make sense to use Quartz in this case. But, the thing is, I have multiple jobs and they are run multiple times. So, I am using Quartz. Is this even possible? You should use SimpleTrigger that fires at specific time and without repeating. TriggerUtils has many handy methods for creating these kind of things. Yes, it's possible! JobKey jobKey = new JobKey("testJob"); JobDetail job = newJob(TestJob.class) .withIdentity(jobKey) .storeDurably() .build(); scheduler.addJob(job, true); scheduler.triggerJob(jobKey
