1. What a job is being stopped....    forums.terracotta.org

During an execution of a lengthy job, such as say generating a report (which may take 3 hours for example) - and we stop the job or abort the job, what happens? Does it kill off the thread/abort the thread? Would that job be able to continue from where it left of? (if so, how do I implement this?) Is it ...

2. Immediately start a job using XML file (XMLSchedulingDataProcessorPlugin)    forums.terracotta.org

In the Quartz 2.x schema there is a way to specify the trigger's start time with "start-time-seconds-in-future" - you could set that to 0 or 1 or something seconds in the future. If you're on Quartz 1.x, then you could try to use a start time in the past, and then be thoughtful about which misfire instruction you set on the ...

3. Failed to recover job    forums.terracotta.org

Hi. The problem I have is that I have set the IsDurable, IsVolatile and RequestRecovery flags to true. Now if during an execution of a job I stop the scheduler service and then later on restart it - I would expect those jobs to run again. Sometimes this happens but other times it does not with an error saying that the ...

I'm working on a project that needs to do lots of processing on stored files and would basically like to have a Quartz scheduled Job that does some processing to determine which files need operated on then passes actual processing off to an ExecutorService.

9. Quartz Job priority    forums.terracotta.org

Hi all, I have some questions regarding a job and a trigger. Jobs and Triggers can be asigned to groups. What are the groups for? How can I fire jobs according to priorities? Let's say I have 5 Jobs firing at the same time but with different priorities and a org.quartz.threadPool.threadCount=3. Is there a way to determine which jobs should fire ...





10. Reschedule failed job to run 5 more times in 5 min intervals    forums.terracotta.org

Annotate the job with @PersistJobDataAfterExecution (or if using Quartz 1.x have it implement the StatefulJob interface). Keep track of the number of failures as a variable in the JobDataMap. Surround the contents of your execute() method with a try-catch block. In the catch block increment and set the failure count in the JobDataMap, then reschedule the job for five minutes into ...

11. SimpleTrigger + Change system date = No job firing    forums.terracotta.org

Hi, I have a quick question about quartz and it's internal scheduler handling. We're using a number of SimpleTrigger's to schedule some polling functions. In some of our test cases, a user will change the systems date back around 14 days. When this happens, all the SimpleTriggers that were scheduled to run every minute stop firing. If the date is changed ...

16. When does a non-durable job get deleted?    forums.terracotta.org

I'm trying to understand exactly when a non-durable job gets deleted. Specifically, is it possible for scheduler.getJobDetail() to return null for a job while the last execution of that job is still running (after all of it's triggers have fired for the last time)? Or is it guaranteed that the JobDetail will remain in the scheduler until after the job has ...

19. Help: My DailyTimeIntervalScheduleBuilder job doesn't run    forums.terracotta.org

I'm giving the user of my app various options on scheduling something. Cron-based jobs (using CronScheduleBuilder) and simple one-time jobs (using SimpleScheduleBuilder) work just fine.

21. stateful job never finishes but is interrupted by new job    forums.terracotta.org

Hi, We're using Quartz (1.8.5) with Spring, and most of our jobs run fine. I'm seeing strange behavior, though, with our one stateful job. The job runs every 5 minutes, and the assumption is there will only be a few records to process each time. What is happening, though, is that the job is starting fine, but never completing. Instead of ...

26. Quartz scheduler and job 'firing' a second early    forums.terracotta.org

Yes, this is possible to happen, and it's hard to avoid unless you schedule the job for 1 second after the hour. There are no guarantees from the Java runtime that a sleep(someMillis) or a wait(someMillis) will actually sleep/wait for as long as asked, and is subject to various thread scheduling and other OS/hardware related issues. Also the code in Quartz ...
