Quartz.NET Quick Start Guide

Welcome to the Quick Start Guide for Quartz.NET. As you read this guide, expect to see details of:

• Downloading Quartz.NET
• Installing Quartz.NET
• Configuring Quartz to your own particular needs
• Starting a sample application

Download and Install

You can either download the zip file or use the NuGet package. NuGet package contains only the binaries needed to run Quartz.NET, zip file comes with source code, samples and Quartz.NET server sample application.

Zip Archive

Short version: Once you've downloaded Quartz.NET, unzip it somewhere, grab the Quartz.dll and Common.Logging.dll from bin directory and start to use them.

Quartz depends only on single third-party library called Common.Logging (which contains logging abstractions that allow you to use the logging provider that suites you the best). You need to have Quartz.dll and Commong.Logging.dll beside your app binaries to successfully run Quartz.NET. So just add them as references to your Visual Studio project that uses them. You can find these dlls from extracted archive from path bin\your-target-framework-version\release\Quartz.

NuGet Package

Couldn't get any simpler than this. Just fire up Visual Studio (with NuGet installed) and add reference to packageQuartz from package manager extension:

• Right-click on your project's References and choose Manage NuGet Packages...
• Choose Online category from the left
• Enter Quartz to the top right search and hit enter
• Choose Quartz.NET from search results and hit install
• Done!

or from NuGet Command-Line:

Install-Package Quartz

Configuration

This is the big bit! Quartz.NET is a very configurable library. There are three ways (which are not mutually exclusive) to supply Quartz.NET configuration information:

• Programmatically via providing NameValueCollection parameter to scheduler factory
• Via standard youapp.exe.config configuration file using quartz-element
• quartz.config file in your application's root directory

You can find samples of all these alternatives in the Quartz.NET zip file.

Full documentation of available properties is available in the Quartz Configuration Reference.

To get up and running quickly, a basic quartz.config looks something like this:

quartz.scheduler.instanceName = MyScheduler
quartz.threadPool.threadCount = 3
quartz.jobStore.type = Quartz.Simpl.RAMJobStore, Quartz

Remember to set the Copy to Output Directory on Visual Studio's file property pages to have value Copy always. Otherwise the config will not be seen if it's not in build directory.

The scheduler created by this configuration has the following characteristics:

• quartz.scheduler.instanceName - This scheduler's name will be "MyScheduler".
• quartz.threadPool.threadCount - There are 3 threads in the thread pool, which means that a maximum of 3 jobs can be run simultaneously.
• quartz.jobStore.type - All of Quartz's data, such as details of jobs and triggers, is held in memory (rather than in a database). Even if you have a database and want to use it with Quartz, I suggest you get Quartz working with the RamJobStore before you open up a whole new dimension by working with a database.

Actually you don't need to define these properties if you don't want to, Quartz.NET comes with sane defaults

Starting a Sample Application

Now you've downloaded and installed Quartz, it's time to get a sample application up and running. The following code obtains an instance of the scheduler, starts it, then shuts it down:

Program.cs

using System; using System.Threading; using Quartz; using Quartz.Impl; namespace ConsoleApplication1 { public class Program { private static void Main(string[] args) { try { // Grab the Scheduler instance from the Factory IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler(); // and start it off scheduler.Start(); // some sleep to show what's happening Thread.Sleep(TimeSpan.FromSeconds(60)); // and last shut down the scheduler when you are ready to close your program scheduler.Shutdown(); } catch (SchedulerException se) { Console.WriteLine(se); } } } } 

Once you obtain a scheduler using StdSchedulerFactory.GetDefaultScheduler(), your application will not terminate by default until you call scheduler.Shutdown(), because there will be active threads (non-daemon threads).

No running the program will not show anything. When 10 seconds have passed the program will just terminate. Lets add some logging to console.

Adding logging

Common.Logging can be configured to use different logging frameworks under the hood; namely Enterprise Library, Log4Net and NLog.

However, to keep things simple for our example we take the simple route and configure logging using code to just log to the console using Common.Logging basic logging mechanism.

Add the following line to the beginning of your Program.cs

Common.Logging.LogManager.Adapter = new Common.Logging.Simple.ConsoleOutLoggerFactoryAdapter { Level = Common.Logging.LogLevel.Info};

Trying out the application and adding jobs

No we should get a lot more information when we start the application.

We need a simple test job to test the functionality, lets create HelloJob that outputs greetings to console.

public class HelloJob : IJob { public void Execute(IJobExecutionContext context) { Console.WriteLine("Greetings from HelloJob!"); } } 

To do something interesting, you need code just after Start() method, before the Thread.Sleep.

// define the job and tie it to our HelloJob class IJobDetail job = JobBuilder.Create<HelloJob>() .WithIdentity("job1", "group1") .Build(); // Trigger the job to run now, and then repeat every 10 seconds ITrigger trigger = TriggerBuilder.Create() .WithIdentity("trigger1", "group1") .StartNow() .WithSimpleSchedule(x => x .WithIntervalInSeconds(10) .RepeatForever()) .Build(); // Tell quartz to schedule the job using our trigger scheduler.ScheduleJob(job, trigger); 

The complete console application will now look like this

using System; using System.Threading; using Quartz; using Quartz.Impl; using Quartz.Job; namespace ConsoleApplication1 { public class Program { private static void Main(string[] args) { try { Common.Logging.LogManager.Adapter = new Common.Logging.Simple.ConsoleOutLoggerFactoryAdapter {Level = Common.Logging.LogLevel.Info}; // Grab the Scheduler instance from the Factory IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler(); // and start it off scheduler.Start(); // define the job and tie it to our HelloJob class IJobDetail job = JobBuilder.Create<HelloJob>() .WithIdentity("job1", "group1") .Build(); // Trigger the job to run now, and then repeat every 10 seconds ITrigger trigger = TriggerBuilder.Create() .WithIdentity("trigger1", "group1") .StartNow() .WithSimpleSchedule(x => x .WithIntervalInSeconds(10) .RepeatForever()) .Build(); // Tell quartz to schedule the job using our trigger scheduler.ScheduleJob(job, trigger); // some sleep to show what's happening Thread.Sleep(TimeSpan.FromSeconds(60)); // and last shut down the scheduler when you are ready to close your program scheduler.Shutdown(); } catch (SchedulerException se) { Console.WriteLine(se); } Console.WriteLine("Press any key to close the application"); Console.ReadKey(); } } public class HelloJob : IJob { public void Execute(IJobExecutionContext context) { Console.WriteLine("Greetings from HelloJob!"); } } }
