I have a method doJob() runs at every 10 seconds like below.
I want to customize the running period at run time. I mean , between 2pm-3pm doJob() runs every 5 seconds. between 3pm-4pm doJob() runs at every 50 seconds.
Is is possible to customize running period at run time?
#Scheduled(cron = "0/10 * * * * ?")
public void doJob() {
}

Note that some scheduling requirements are too complicated to express with a single trigger - such as "every 5 minutes between 9:00 am and 10:00 am, and every 20 minutes between 1:00 pm and 10:00 pm". The solution in this scenario is to simply create two triggers, and register both of them to run the same job.
You won't be able to use the same jobs but certainly two different jobs
Job 1 (between 2pm-3pm runs every 5 seconds)
0/5 * 2-3 * * ?
Job 2 (between 3pm-4pm runs at every 50 seconds)
0/50 * 3-4 * * ?

I have this quartz cron expression: exp = "0 * * ? * *" that runs every minute.
I use this expression as a trigger to call a HTTP POST method every minute.
The problem is that it calls the post method multiple times.
I need an expression that will execute one time in a minute.
Any suggestion how to do that?
This works with Quartz.
Every 1 minute, exactly at the start of a minute - 0 0/1 * * * ?
How about a simple schedule trigger instead?
trigger = newTrigger()
.withIdentity("trigger7", "group1")
.withSchedule(simpleSchedule()
.withIntervalInMinutes(1) )
.build();

It may happen because request lasts longer than 1 min. You can simply annotate class implemented with Jobs with #DisallowConcurrentExecution, which disallow your job execute multiple times in exact time.
You can check example .
use this expression :
"* * * * *"
i.e 5 asteriks
try using that.

Currently I'm using Spring annotation to schedule my task every 20 minutes:
#Scheduled(fixedRate = 1200000)
I want to change schedule that my task will execute only between 2AM and 5AM (still every 20 minutes).
Is it possible with Spring Scheduler? Or are there any best practices to solve this problem?
Thanks
#Scheduled has 'cron' element so you can use full power of cron
#Scheduled(cron = "0 0/20 2-5 * * ?")
0/20 -> every 20mins
2-5 -> between 2 to 5 AM
I want to execute cron job between specific time. i.e. Cron job should execute every 15 minutes between 7:03 to 21:04?
I can manage between 7 to 9 but can't schedule between 7:03 to 9:05.
After understanding your requirement clearly, AFAIK, you need two schedulers:
First Scheduler (runs between hours 07:00 to 21:00):
Cron expression should be like 0 3/15 7-20 * * *
0 - seconds
3/15 - runs at 3rd, 18th, 33rd, 48th minutes of each hour
7-20 - starting from 07AM to 08PM (included)
Second Scheduler (runs ONLY at 21:04):
Cron expression should be like 0 4 21 * * * (which runs ONLY at 21:04)
Try with below cron expression
0 3/15 7-21 * * ?
If you need it to run daily, you can try to use DailyTimeIntervalTrigger.
There you can set the start time (7:03) and end time (21:04) and choose the interval you want (in seconds, minutes, hours...)
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 * * ? // every 30 min starts from 9:00
I have a Quartz job that is to fire for a certain time repeatedly. Unfortunately it does not fire for some unknown reasons.
Here is my cron expression :
0/5 0 0 * * ?
So basically the job should be fired every 5 seconds. This is the part which does not work.
Now the wierd thing is when I changed the cron expression to
0 0 0/1 * * ?
which fire the job at every 1 hour. The job is fired and I can see that the method is being invoked on the Java side.
I have tried also on the minute field eg. 0 0/5 0 * * ? for every 5 minutes but it does not fire either.
I don't know what is the behavior is that the other two expression are not firing. Any help would be very much appreciated.
Here is also my seam.quartz.properties file
Configure Main Scheduler Properties
org.quartz.scheduler.instanceName QuartzScheduler
org.quartz.scheduler.instanceId AUTO
org.quartz.scheduler.rmi.export false
org.quartz.scheduler.rmi.proxy false

org.quartz.threadPool.threadCount 10
Configure JobStore
org.quartz.jobStore.misfireThreshold 60000
org.quartz.jobStore.class org.quartz.simpl.RAMJobStore
I am using Jboss 5.1.0, Seam 2.2 and Quartz 1.8.3.
0/5 0 0 * * ?
The above cron expression will schedule the job to trigger every 5 seconds during minute 0 and hour 0 daily. In other words, the first minute every day, the job will execute 12 times.
I assume you want it to trigger any hour, that is every 5 seconds regardless of the hour.
Replace the two zeros indicating minute and hour with the * wildcard. Also, you don't need ? which means no specific value. The below expression will schedule the timer every 5 seconds, regardless of which hour or minute it is:
0/5 * * * * *
The reason why 0 0 0/1 * * ? is "working" is because you undertand the expression correctly, which you didn't with the ones that were "not working". Basically it means every 1 hour at the start of a new hour (minute 0 and second 0).
