Hi,  
I want to set a Cron job in my application to execute 1 specific method to update the database value.  
I have checked the Servoy wiki and found that we can set a Cron job using addCron method.  
But after implementation I have found that method is being executed only once.  
I want to set Cron for every 5 mins. Please share the syntax to add Cron job.  
And I want to run without client login.

Thanks in advance.

Abhishek

Hi Abishek,

Cron uses a specific format to define when a job should run (_seconds, minutes, hours, day of month, month, day of week, year_). It’s very versatile which also makes a bit complex.  
To run a job every 5 minutes you use the time-string “0 0/5 \* \* \* ?” (_0 seconds, every 5 minutes starting from the top of the hour_).  
You can read more about it [here](http://www.quartz-scheduler.org/documentation/quartz-2.x/tutorials/crontrigger.html).

Hope this helps.
