Multi Job with Quartz Scheduler not running

Question

I've scheduled three job in my Service:

public partial class Service : ServiceBase
    {
        private IScheduler scheduler;
        private static log4net.ILog _logFile =
            log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

        public Service()
        {
            InitializeComponent();
        }

        protected override async void OnStart(string[] args)
        {
            _logFile.Info("Service OnStart");

            var factory = new StdSchedulerFactory();
            scheduler = await factory.GetScheduler();

            await scheduler.Start();
            var job = JobBuilder.Create<SearchJob>()
                .WithIdentity("SearchJob", "group1")
                .Build();

            var trigger = TriggerBuilder.Create()
                .WithIdentity("SearchJobtrigger", "group1")
                .StartNow()
                .WithCronSchedule(Settings.Default.SearchCronExp)
                .ForJob(job)
                .Build();

            var jobUpload = JobBuilder.Create<UploadJob>()
           .WithIdentity("UploadJob", "group1")
           .Build();

            var triggerUpload = TriggerBuilder.Create()
                .WithIdentity("TriggerUploadJob", "group1")
                .StartNow()
                .WithCronSchedule(Settings.Default.UploadCronExp)
                .ForJob(jobUpload)
                .Build();

            var jobAwaiter = JobBuilder.Create<AwaiterJob>()
                .WithIdentity("AwaiterJob", "group1")
                .Build();

            var triggerAwaiterJob = TriggerBuilder.Create()
                .WithIdentity("triggerAwaiterJob", "group1")
                .StartNow()
                .WithCronSchedule(Settings.Default.AwaiterCronExp)
                .ForJob(jobAwaiter)
                .Build();

            await scheduler.ScheduleJob(job, trigger);
            await scheduler.ScheduleJob(jobUpload, triggerUpload);
            await scheduler.ScheduleJob(jobAwaiter, triggerAwaiterJob);

            _logFile.Info("End Service OnStart");
        }

        protected override async void OnStop()
        {
            _logFile.Info("Service OnStop");
            await scheduler.Shutdown();
        }
    }

Consulting the log, I notice that the only the first job starts, the other two never start but there are no errors in the log. I tested the service in debug and the jobs are executed correctly, while installing the service compiled in Release no, the three services have a CronExp of 1,10,30 minutes respectively between one execution and the other

Answer 1

There wont be any effect of calling startNow() on a CronTrigger as it triggers the job based on cron expression supplied unlike time based SimpleTrigger.
Your cron expression tells Quartz to run every x mins starting 0th minute of ever hour. Unless you start the scheduler at exactly 0th min, you will not see startNow effect.

Hope this is clear to you. Refer Quartz tutorial-lesson-06 tutorials/documentation for more details.
meaning your jobs will only run as per cronjob expressions.
