quartz.net

问题 I am implementing quartz.net scheduler to my project, and have some questions about the workings of this library: What happens if one job raises an exception without a catch block (unhandled exception)? Would this cause the process to terminate and AppDomain Unloading? Would other jobs suffer? Does Quartz.net lib try to restart jobs that raised unhandled exceptions? Or should I implement it manually in my project? Thanks. 回答1: From what I can determine being a user of Quartz.net myself. If

问题 I just started with Quartz.net and I have it running as a service. I created a Job and moved the resulting .dll to the Quartz folder and added a new entry to the jobs.xml file to kick it off every 3 seconds. I updated the job .dll but it is in use by Quartz (or is locked). Is it possible to update the .dll without restarting the Quartz service? If not what would happen to a long running job if I did stop/start the Quartz service? 回答1: You cannot update the job dll without restarting the

问题 I am new to Quartz.NET so bear with me please. I would like to run Quartz.NET as a stand-alone service which runs jobs. I would like to create a different assembly containing all the jobs I need to run and have Quartz configured to run these jobs from my assembly. Thus, whenever I create a new job, I add this to my assembly and all I am left to do is to replace the old assembly and restart the Quartz service. Is this possible? Could anyone please show/redirect me to a code example showing how

问题 How to mark my IJob implementation as durable? I couldn't find any reference to this in quartz .net documentation and I do not use any xml job configurations. Shouldn't there be some kind of attribute like PersistJobDataAfterExecution , DisallowConcurrentExecution or boolean property in IJob interface? 回答1: var job = JobBuilder.Create<TestJob>() .WithIdentity(typeof(TestJob).Name) **.StoreDurably(true)** .Build(); 来源： https://stackoverflow.com/questions/33612215/how-to-mark-job-as-durable-in

问题 I have this entry in web.config <appSettings> <add key="pingUrl" value="http://examplesite.com/login.aspx"/> </appSettings> I have the below code in Global.asax.cs to automatically start the IIS when it is recycle void Application_End(object sender, EventArgs e) { try { string pingUrl = ConfigurationManager.AppSettings["pingUrl"]; WebClient http = new WebClient(); string Result = http.DownloadString(pingUrl); } catch (Exception ex) { string Message = ex.Message; } } My Question is can I

问题 I am running Quartz.NET as a service and I add my jobs directly in the quartz-jobs.xml file. So in order to add and delete jobs and triggers I deal with Xml and not the normal functions. I would like to know how can we get the next fire time of a trigger just by looking at its cron expression? 回答1: You can get the next fire time from given cron expression: var expression = new CronExpression("0 26 13 17 10 ? 2015"); DateTimeOffset? time = expression.GetTimeAfter(DateTimeOffset.UtcNow); 来源：

问题 We are using Quartz.Net to trigger jobs on a schedule in a Windows Service . I have a situation where I have to Trigger a job every 5 minutes from Start DateTime till End DateTime . After the job is completed we need to calculate the Next Start DateTime and Next End DateTime and save to the DB - For this I tried to override the JobListener which has a method: JobWasExecuted public class xPTJobListener : JobListenerSupport { public override string Name { get { return "xPTJobListener"; } }

问题 I am using a cron trigger with misfire-instruction set to FireOnceNow in quartz.net-2.0 set up with AdoJobStore and using XMLSchedulingDataProcessorPlugin . cron-expression is set so the job will trigger every 1 minute: 0 0/1 * * * ? . The job scheduler is set to start in Global.asax.cs . Expected behaviour: If the server is stopped when a job should trigger but it is restarted before the next trigger then it should trigger once immediately. Example: First job triggers at 00:01:00 . I stop

问题 I am trying to create some Quartz.Net jobs following my own answer from this question. However, if the job is fairly complex and required "scoped" ( services.AddScoped<.., ...> ) services, the example does not work because jobs are created as singletons. If I change them to be scoped, the serviceProvider does not contain the services I need. I have managed to make it work using the following code: Startup.cs /// <summary> /// service provider to be used by qiaryz job factory which cannot use

问题 Am I understanding this correctly? ISchedulerFactory sf = new StdSchedulerFactory(); IScheduler sched = sf.GetScheduler(); sched.Start(); Is the StdSchedulerFactory a singleton? What I want to achieve is in my global,asax on Application_Start to start up the quartz scheduler, and then later on in one of my classes create the job, the trigger, get a handle again to the scheduler, and schedule the job/trigger But as it turns out, I need to re-start the scheduler, I thought it was already
