I am using quartz to schedule my jobs,
I need to execute a job at 2:00am every day and repeat the execution 5 times every 10 minutes, any ideas?
the result should be: 2:00 2:10 2:20 2:30 2:40
Thanks in advance.
I would look at the Quartz CronTrigger, and particularly the usage of / to specify every 'n' minutes/hours whatever.
I think you would need
0 0,10,20,30,40 2 * * ?
to fire at 2am and then 2.10am-2.40am every 10 minutes.
Just specify the schedule times as a cron string for the CronTrigger like this:
0 0,10,20,30,40 2 * * *
Use a CronTrigger with a cron expression that describes the exact times you want it run. For every day at 2:00, 2:10, 2:20, 2:30, 2:40, use:
0 0,10,20,30,40 2 * * ?
A simple solution would be to simply have 5 tasks, one for every 10 minutes.

Is it possible to schedule quartz job for every 3 business days ?
I'm seeing some examples time or specific day or month examples but how to write quartz expression every 3 business days with any month and any year ?
I have tried 0 0 */3 * 1-5 * but got error day-of-week and a day-of-month is not implemented.
Thanks
You cannot specify both a day-of-week (1-5) and a day-of-month (*/3) - one of them must be ?.
How about 0 0 0 ? * MON-FRI/3? Or 0 0 0 ? * MON,THU,TUE,FRI,WED?
EDIT: I tested above - it does not work (the / only seems to work for non-intervals, and the MON,THU,TUE,FRI,WED gets normalized to MON-FRI).
Looking at the source of the next-trigger-day-computation, I am quite confident now that "every 3 business days" is not possible with a single Quartz Scheduler Cron-Expression.
What possibly could work would be a collection of expressions. The "Related" links on the right might give some inspiration.
For my enterprise application, i need do the batch operation with time of intervals.
While referring quartz scheduler, there are two types. One is simple trigger and another one is cron trigger.
I am confusing about these concepts. Please explain me with simple example.
Please refer to the examples given in the documentation.
CronTrigger
CronTrigger is often more useful than SimpleTrigger, if you need a job-firing schedule that recurs based on calendar-like notions, rather than on the exactly specified intervals of SimpleTrigger.
Some Examples
“every Friday at noon” or “every weekday and 9:30 am”, or even “every 5 minutes between 9:00 am and 10:00 am on every Monday, Wednesday and Friday during January”, .
CronTrigger Example 1 - an expression to create a trigger that simply fires every 5 minutes
“0 0/5 * * * ?”
CronTrigger Example 2 - an expression to create a trigger that fires every 5 minutes, at 10 seconds after the minute (i.e. 10:00:10 am, 10:05:10 am, etc.).
“10 0/5 * * * ?”
CronTrigger Example 3 - an expression to create a trigger that fires at 10:30, 11:30, 12:30, and 13:30, on every Wednesday and Friday.
“0 30 10-13 ? * WED,FRI”
CronTrigger Example 4 - an expression to create a trigger that fires every half hour between the hours of 8 am and 10 am on the 5th and 20th of every month. Note that the trigger will NOT fire at 10:00 am, just at 8:00, 8:30, 9:00 and 9:30
“0 0/30 8-9 5,20 * ?”
I am having trouble with finding a cron expression for Spring Quartz-scheduler.
I know that the cron expression that runs for every 5 mins was:
"0 0/5 * * * ?".
I am looking for cron expression that runs continuously once every 5 mins.
1:05 , 1:10 , 1:15 , 1:20.....
or
2:10 , 2:20 , 2:30 , 2:40 .....
Use http://www.cronmaker.com/ online tool which helps you to build cron expressions from based on in your inputs.
I currently have a Quartz cron trigger that runs every 10 minutes Monday to Friday with this expression:
0 0/10 * ? * Mon-Fri
I am looking for a way to start the schedule from 1am on Monday and then run it every 10 minutes for the remainder of the week. Is this possible with a single cron expression?
An expression such as 0 0/10 1-23 ? * Mon-Fri would start at 1am but not run between 12 midight and 1am on subequent days, which is not what I need.
I'm not an expert on Quartz, but couldn't you schedule your job twice?
0 0/10 1-23 ? * Mon
0 0/10 * ? * Tue-Fri
The cron expression you told works fine i guess. You can verify it here http://www.cronmaker.com/ by entering your cron expression 0 0/10 * ? * Mon-Fri and check the next schedule.
I need a particular job to be run every 3hrs and 15 mins .
Will this expression serve my purpose ?
batch.backupscores.cronExpression=0 0/15 0/3 * * ?
thanks in advance .
No, this expression won't work and I believe you can't express this using Cron. But you can use simple trigger instead.
Running job every 195 minutes will work (3 * 60 minutes + 15).
0 15 0,3,6,9,12,15,18,21 * * ?
this will serve the purpose
