Question

Answer 1

I assume you have a Schedulable class created? You can schedule it using the system.schedule command:

system.schedule('Name of Job', '0 0 * * * ?', new MySchedulableClass());

Where '0 0 * * * ?' is a CRON expression to run the job every hour.

More details here: https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_scheduler.htm

Answer 2

This simple script should be all you need if you want to test your class in the dev console.

scheduledClassExample abc = new scheduledClassExample();
abc.execute(null);

Answer 3

Something like this

String CRON_EXP = '0 30 * * * ?';
SWD_SoftwareDownloadScheduler sch = new SWD_SoftwareDownloadScheduler();
system.schedule('SWD_SoftwareDownloadScheduler - Hourly (TEST)', CRON_EXP, sch);    

This runs hourly 30 minutes past the hour.

Answer 4

try this:

apexScheduledJob myJob = new apexScheduledJob ();
String sch = '0 0 0,2,4,6,8,10,12,14,16,18,20,22 ? * *';
System.schedule('My Job', sch, myJob);

Answer 5

We can use Cron expression to run scheduled job-in-developer-console. Referal link:- http://docs.oracle.com/cd/E12058_01/doc/doc.1014/e12030/cron_expressions.htm

  Datetime dt = Datetime.now().addMinutes(1);
  String CRON_EXP = '0 '+ dt.minute() + ' * ' + dt.day() + ' ' + dt.month() + ' ? ' + dt.year();
  ScheduleBatch.SchedulerMethod('Sample_Heading', CRON_EXP, new ScheduleBatch () );   

Answer 6

Run a Schedule Job NOW

ScheduleSalesTargets c = new ScheduleSalesTargets();
c.execute(null);

OR

Check the Time Now, if it is, let's say 10:39 AM, in your clock, then set the minute to 41. This will schedule the job for 10:41 AM just two minutes from now. But, if you set minute value to 38, then it will schedule to next hour 11:38 AM

ScheduleSalesTargets c = new ScheduleSalesTargets();
String sch = '0 0 * * * ?';
System.schedule('Sales Target Job11',  '0 41 * * * ?', c);
