Schedule Apex to run every 5 or 10 minutes in Salesforce

Hello Everyone, In this post, We are going to see a code example that illustrate you, how you can schedule an apex class in every 5 or in 10 minutes duration in salesforce using CRON expression. This is too simple, so without wasting time let's get started,

Schedule Apex in every 5 or 10 minutes in Salesforce

In apex, By default scheduled job run in every 1 hour using CRON expression but you can scheduled this job in every 5 minutes or 10 minutes duration. Scheduled a class in every 5 minutes or 10 minutes is not possible to do through the standard Salesforce user interface, But you can achieve this by using a small piece of code. So here are the steps,

1. Navigate to Developer Console | New | Apex Class, create a new apex class “SampleScheduler” and replace the following markup in the class.

 global class SampleScheduler implements Schedulable{
    global void execute(SchedulableContext SC){ 
        //Code logic goes here..
    }
 }

2. To schedule class in every 5 minutes, Navigate to Developer Console | Debug | Open Execute Anonymous Window. Copy and paste the below code and click on “Execute” button.

 System.schedule('SampleScheduler 1',  '0 00 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 2',  '0 05 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 3',  '0 10 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 4',  '0 15 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 5',  '0 20 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 6',  '0 25 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 7',  '0 30 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 8',  '0 35 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 9',  '0 40 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 10', '0 45 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 11', '0 50 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 12', '0 55 * * * ?', new SampleScheduler());

3. To schedule class in every 10 minutes repeat step 2 with following CRON expression.

 System.schedule('SampleScheduler 1', '0 0 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 2', '0 10 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 3', '0 20 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 4', '0 30 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 5', '0 40 * * * ?', new SampleScheduler());
 System.schedule('SampleScheduler 6', '0 50 * * * ?', new SampleScheduler());

If you want to check apex class in scheduled or not then Navigate to Setup | Jobs | Scheduled Jobs.

 The following are some example of CRON expressions:
