Quartz Clustering - triggers duplicated when the server starts

由 江枫思渺然 提交于 2019-12-07 05:18:43
问题 We are facing an issue while using Quartz 2.1.6 with Spring 3.1 in a clustered setup (with the JDBC data store). Current context: Jobs and CRON triggers are defined in the spring configuration file (see below) overwriteExistingJobs property is set to true in SchedulerFactoryBean, so we don't get new job definitions added to the DB with each deployment. However, after each deployment in the cluster, it seems that each node re-creates the trigger data. For example, if we have 2 triggers

Configuring Quartz.NET with SQL Server AdoJobStore

由 只愿长相守 提交于 2019-12-07 03:07:43
问题 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=

Specify arbitrary start and end times for cron job

问题 For Quartz Cron, is it possible at all to specify a cronexpression that corresponds to: Run every 6 minutes, starting from 9:12 AM until 5:37 PM. I attempted to write the cronexpression 0 12-37/6 9-17 ? * * but this does only runs once an hour. I also understand that the cronexpression 0 /6 9-17 ? * * corresponds to Run every 6 minutes between the hours of 9 AM and 5 PM . But is there any way to constrain the starting and ending minutes on that cronexpression? More generally, can I specify an

quartz jobDetail requestRecovery

由 旧巷老猫 提交于 2019-12-06 23:00:26
问题 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? 回答1: A " Recovery situation " is the generic term, one kind

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

Quartz Scheduler: How to dynamically read a quartz property from Java via API?

由 孤街醉人 提交于 2019-12-06 16:13:25
Quartz is usually configured via quartz.properties on the classpath. e.g.: org.quartz.scheduler.instanceName = BagginsScheduler org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool org.quartz.threadPool.threadCount=5 org.quartz.threadPool.threadPriority=1 From within the same application that will run the Quartz jobs, I'd like to read out the properties. Reading the scheduler name is easy: Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler(); String name = scheduler.getSchedulerName(); But how can I read the `threadPriority' property? The following does not work: scheduler

Quartz start at a specific time and run at specific interval

I have been trying to come up with a cron expression to start a job at 8.30am and run every 30 mins until midnight and restart at 8.30am next day. I came up with following expression but only thing it lacks is starting at 8.30am. Rather than starting at 8.30 it starts at 8.00. 0 0/30 8/1 * * ? Is it even possible to do what I'm trying to do? I'll be using java quartz2.x.x It seems to be not possible in single expression. There is good link, to create your cron expression, you may refer Cron Maker ==Updated== You can have two cron expression 0 30/30 8 ? * * * //every day 8:30 And, 0 0/30 9-23 *

Hello everyone I want to schedule message sending using quartz. But i dont know really how. I can send message to given mobile no but for scheduling its difficult. What I am trying is 1) I am taking message, mobile no, period, from user (JobSchedule.jsp) 2) I am calling a Jobscheduler Servlet (JobSchdeduleServlet.java) .. here I dnt know how to pass variables to class(TestJob.java) // JobSchdeduleServlet.java .. //specify the job's details.. JobDetail job = JobBuilder.newJob(TestJob.class) .withIdentity("testJob") .build(); // SimpleScheduleBuilder.simpleSchedule() // .withIntervalInSeconds

Remotely connect to Quartz Scheduler

由 你离开我真会死。 提交于 2019-12-06 14:41:50
I am trying to connect to the Quartz scheduler remotely, so I can get a list of jobs that are scheduled to run. On the server application I used the below code: NameValueCollection properties = new NameValueCollection(); properties.Add("quartz.scheduler.instanceName", "OlScheduler"); properties.Add("quartz.scheduler.instanceId", "Ol"); properties.Add("quartz.threadPool.type", "Quartz.Simpl.SimpleThreadPool, Quartz"); properties.Add("quartz.threadPool.threadCount", "5"); properties.Add("quartz.threadPool.threadPriority", "Normal"); properties.Add("quartz.scheduler.registryPort", "1099");

Quartz jobs - disallow concurrent execution group-wide?

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-06 14:34:57
using Quartz, I'd like few jobs (say about 10) to execute as a chain - i.e. NOT concurrently. They should be executed after an "accounting day change" event occur but since they all access the same DB, I dont want them to start all together. I want them to be executed sequentially instead (order doesnt matter). I have an idea to put them into a group - say "account_day_change_jobs" and configure Quartz somehow to do the rest for me :-) Means - run sequentially all jobs from the group. I tried the API doc (both 1.8 and 2.1), tried google but didnt find anything. Is it possible? Is it even
