Hi, I have the following schedulable class below and i wanted to be able to schedule it to run at 12am through the UI by navigating to schedule apex and then setting it to run every day at 12am. However, after this job has ran, i want it to schedule a subsequent job (same class) to run in the next hour. Is this possible?

The goal is to only schedule it through the UI to run at 12 Am and then it will automatically schedule the remaining jobs 1 hour later.

global class SampleClass implements Schedulable{
    global void execute(SchedulableContext alistContext) {
        Database.executeBatch('myBatchClass', 100);

       //when database executebatch is done, I want to schedule the same job 1 hour later
       String cron_exp = '0 0 1 * * ?';
       String jobName = 'somename';
       System.Schedule(jobName, cron_exp, new SampleClass())
Here is my apex batch:

global class EmailAlertToQuoteProposalApprovalUser implements Database.Batchable<sObject>, database.stateful{

And here is schedulable:  I want to run batch file after every 5 minutes... Please Help

global class scheduledQuoteReminderBatchable implements Schedulable {

i have an bach apex class i want to write a schedule class for this batch apx class for evereday afternoon  at 1PM


Can anyone provide sample code for schedule apex class



Current documents has no example on how to schedule apex jobs every 10 mins. I tried with unix cron job syntax style (like 0,10,20,30,40,50 slots), that doesn't work.


Any help would be appreciated.
