How to schedule my batch class for every 6 hours ?

How to schedule my batch class for every 6 hours ?
This is my scheduler -
  
global class UpdateBatchSchedule implements Schedulable{
    global void execute(SchedulableContext ctx) {
        UpdateBatch p = new UpdateBatch();
        database.executeBatch(p,200);
    }  
}

Hi,

Can you try the schedular as below cron job for scheudling it. it runs at 12am, 6AM,12PM,6PM every day


  
global class UpdateBatchSchedule implements Schedulable{
    global void execute(SchedulableContext ctx) {
        UpdateBatch p = new UpdateBatch();
        database.executeBatch(p,200);
    }  
}


You can use the same class which you have written . Just execute this in anonomous window.
  
UpdateBatchSchedule m = new UpdateBatchSchedule();

String sch = '0 0 0,6,12,18 ? * *';
String jobID = system.schedule('Merge Job', sch, m);


Let me know if you face any issues.

If this solution helps, Please mark it as best answer.

Thanks,

Hi @Sai Praveen

Do I have to run it every time in anonymous window?

Thanks
Sai PraveenSai Praveen (Salesforce Developers) 
Hi,

No it is not needed to run every time. If you run this once in each sandbox then this class will be scheduled every 6 hours like I mentioend above.

Thanks,

Hi,

Yeah it will be same in production as well. You have to run this once in production as well.
