quartz-scheduler

I am implementing Quartz Job Store on Oracle DB using Spring Framework. My ApplicationContext.xml is below <bean id="driverJob" class="org.springframework.scheduling.quartz.JobDetailBean"> <property name="jobClass" value="BatchFileCollector" /> </bean> <bean id="ranchTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean"> <property name="jobDetail" ref="driverJob" /> <property name="startDelay" value="2000" /> <property name="repeatInterval" value="10000" /> </bean> <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list>

I have a Quartz job that has already been scheduled. I want to update the JobDataMap associated with it. If I get a JobDataMap with JobDataMap jobDataMap = scheduler.getJobDetail(....).getJobDataMap() , is that map "live"? ie. if I change it, will it be persisted in the scheduler? If not, how do I persist it? See http://www.quartz-scheduler.org/docs/tutorial/TutorialLesson03.html : A Job instance can be defined as "stateful" or "non-stateful". Non-stateful jobs only have their JobDataMap stored at the time they are added to the scheduler. This means that any changes made to the contents of the

I am using tomcat version 6.0. My requirement is that when tomcat starts up, I would like to start a QuartzScheduler which will schedule some jobs at a regular interval. I am trying to figure out the best possible way to do it. Here are the options that I could think of - I can do this via a servlet with " load-on-startup " descriptor in web.xml file to start the scheduler and schedule the jobs inside the servlet. Can be done using a ContextListener (this sounds a better approach to me than 1). This might be a clean approach to start the scheduler inside the contextInitialized method and

I'd like to maintain a history of jobs that were scheduled by a Quartz scheduler containing the following properties: 'start time', 'end time', 'success', 'error'. There are two interfaces available for this: ITriggerListener and IJobListener (I'm using the C# naming convention for interfaces because I'm using Quartz.NET but the same question could be asked for the Java version). IJobListener has a JobToBeExecuted and a JobWasExecuted method. The latter provides a JobExecutionException so that you know when something went wrong. However, there is no way to correlate JobToBeExecuted and

We have several Quartz jobs configured in our application. During development, we leave the quartz scheduler in standby - however, we sometimes want to start a job manually (for development purposes). If I call fireTrigger, it tells me I need to start the scheduler. However, if I start the scheduler, it will also immediately schedule all the other jobs, which is not what I want (since they may trigger while I'm debugging the manually fired job). I could pause all triggers when I start the scheduler, but then I have to deal with misfire instructions etc. Is there a simple way to fire off a job

I am new to Spring-boot(version 1.3.6) and Quartz and I am wondering what is the difference between making a task with Spring-scheduler : @Scheduled(fixedRate = 40000) public void reportCurrentTime() { System.out.println("Hello World"); } And the Quartz way : 0. Create sheduler. 1. Job which implements Job interface. 2. Create JobDetail which is instance of the job using the builder org.quartz.JobBuilder.newJob(MyJob.class) 3. Create a Triger 4. Finally set the job and the trigger to the scheduler In code: public class HelloJob implements Job { public HelloJob() { } public void execute

I wonder how to pass an instance variable externally in Quartz? Below is pseudo code I would like to write. How can I pass externalInstance into this Job? public class SimpleJob implements Job { @Override public void execute(JobExecutionContext context) throws JobExecutionException { float avg = externalInstance.calculateAvg(); } } Rips you can put your instance in the schedulerContext.When you are going to schedule the job ,just before that you can do below: getScheduler().getContext().put("externalInstance", externalInstance); Your job class would be like below: public class SimpleJob

It seems there is a limit on the number of jobs that Quartz scheduler can run per second. In our scenario we are having about 20 jobs per second firing up for 24x7 and quartz worked well upto 10 jobs per second (with 100 quartz threads and 100 database connection pool size for a JDBC backed JobStore), however, when we increased it to 20 jobs per second, quartz became very very slow and its triggered jobs are very late compared to their actual scheduled time causing many many Misfires and eventually slowing down the overall performance of the system significantly. One interesting fact is that
