    Hi Mohit,

    Cron expression for scheduling batch in Salesforce
    Cron expression

    Every 30 minutes - '0 30 * * * ?'

    Every hourly - '0 0 * * * ?'

    Every 5 min - '0 5 * * * ?'

    Every 10 min - '0 10 * * * ?'

    Every 15 min - '0 15 * * * ?'

    Every 20 min - '0 20 * * * ?'

    Every 25 min - '0 25 * * * ?'

    Every 30 min - '0 30 * * * ?'

    like upto 55 or 59 your wish

    Note: If you schedule your batch for every 5 min '0 5 * * * ?'. It means it will run every hours 5th minute.

    It will not run every 5 minutes

    If you want to run for every 5 min then you need to schedule 12 times with different different cron expression like for 5 min, 10 min, 15min like upto 60 min..

     

    but you can use below code to schedule your batch for every 5o minutes

    global class SelfSchedule implements schedulable
    {
    global void execute( SchedulableContext SC )
    {

    // do whatever it is you want to do here

    SelfSchedule.start();

    // abort me and start again
    System.abortJob( SC.getTriggerId() );
    }

    public static void start()
    {
    // start keepalive again in 5 mins
    Datetime sysTime = System.now().addSeconds( 3000);
    String chronExpression = '' + sysTime.second() + ' ' + sysTime.minute() + ' ' + sysTime.hour() + ' ' + sysTime.day() + ' ' + sysTime.month() + ' ? ' + sysTime.year();
    System.schedule( 'SelfSchedule ' + sysTime, chronExpression, new SelfSchedule() );
    }

    }

    Hope it may Helps you

    thanks
