Following is the snippet of anonymous code which will help you to schedule your apex for any interval. The Time parameter is not well structured and because of it I had to put in efforts in compiling the time parameter.
Update (@23 Nov 2011) – Use below code to schedule apex class 10mins (change it as per your need) from now
String str = system.now().addMinutes(10).format(‘ss mm HH dd MM ? yyyy’);
System.schedule(‘Registration Report’, str , new scheduledApexClassName());
I am documenting all the parameters neatly, which will help you to schedule apex to run at any time interval even minutes. Below code executes Apex every 10 minutes.
scheduledApexClassName m = new scheduledApexClassName();
String seconds = ‘0’; //Execute at Zero Seconds
String minutes = ‘10,20,30,40,50’; //Execute at every 10th minute of hour
String hours = ‘*’; // Execute Every Hour
String dayOfMonth = ‘*’; // Execute Every Day of the Month
String month = ’11’; //Execute only in November(11)
String dayOfWeek = ‘?’; //Execute on all 7 days of the Week
String year = ‘2009’; //Execute only for year 2009//Seconds Minutes Hours Day_of_month Month Day_of_week optional_year
String sch = seconds + ‘ ‘ + minutes + ‘ ‘ + hours + ‘ ‘ + dayOfMonth + ‘ ‘ + month + ‘ ‘ + dayOfWeek + ‘ ‘ + year;
//String sch = ‘0 10,20,30,40,50 * * 11 ? 2009’;system.schedule(‘Registration Report’, sch, m);
Execute above code in system log i.e., execute above annonymous code and it will schedule your Apex Class.

System.StringException: Minute and Second values must be between 0 and 59
Hi Chirag, We can’t provide comma seperatwed integer values in minutes. It excepts only integer from 0 to 59.
I am having same issue, I need to schedule my job to run every 3 minutes and want to use comma seperated minutes, but it won’t accept it. If you come up with solution, let me know, thanks.
I get ‘ trigger must be associated with a job detail’
This was very helpful! Thanks didn’t think to run this in the system log. Though you can’t have apex schedule something more frequently than once per hour.
hi chirag, what if i want to update 2 leaves for an employee at the start of every month, can i also have the coding plzzzzzzzzzz
Please update your site, the syntax you specified is based on *nix CRON,
As many other reads pointed out, the current [ Winter 12 ] with Force.IDE version 23 only support a single integer for the minute field.
So if you want to execute a job every 10 minutes, you will have a schedule 6 jobs…..
I’ve updated the post with a more optimised code to schedule apex class 10mins (change it as per your need) from now.
Let me know if you need anything else, would be happy to help and get your issue resolved.
Hey thanks !!!!!
Can we have the cron expression dynamically….?
I mean that can we assign the current datetime value to it.So, it will be comfortable while a job is getting scheduled from a trigger……….
How will you deploy this scheduler in production where you can not schedule it with developer console.
Do we need to then create a VF page & click a button and call the class to execute this? Is there a cleaner way to deploy?
how can set scheduler startTime, endTime tynamiclly?
wait
