支持集群高可用的開發方案

Quartz.net的數據庫表結構

如果支持集群與持久化，單靠本機的內存和xml來保存計算任務調度的各種狀態值，可想而知，是困難的。所以支持數據庫這樣的解決方案，OpenSymphony組織怎么可能會給遺漏。

官方提供的各種數據庫腳本：https://github.com/quartznet/quartznet/tree/master/database/tables

下面我給大家展示下quartz任務調度的MS SQLSERVER表結構

部分我們擴展開發常用到的表及字段說明

1、QRTZ_JOB_DETAILS：存儲的是job的詳細信息，包括：[DESCRIPTION]描述，[IS_DURABLE]是否持久化，[JOB_DATA]持久化對象等基本信息。

2、QRTZ_TRIGGERS：觸發器信息,包含：job的名，組外鍵，[DESCRIPTION]觸發器的描述等基本信息，還有[START_TIME]開始執行時間，[END_TIME]結束執行時間，[PREV_FIRE_TIME]上次執行時間，[NEXT_FIRE_TIME]下次執行時間，[TRIGGER_TYPE]觸發器類型：simple和cron，[TRIGGER_STATE]執行狀態：WAITING，PAUSED，ACQUIRED分別為：等待，暫停，運行中。

3、QRTZ_CRON_TRIGGERS：保存cron表達式。

4、QRTZ_SCHEDULER_STATE：存儲集群中note實例信息，quartz會定時讀取該表的信息判斷集群中每個實例的當前狀態，INSTANCE_NAME:之前配置文件中org.quartz.scheduler.instanceId配置的名字，就會寫入該字段，如果設置為AUTO,quartz會根據物理機名和當前時間產生一個名字。??[LAST_CHECKIN_TIME]上次檢查時間，[CHECKIN_INTERVAL]檢查間隔時間。

5、QRTZ_PAUSED_TRIGGER_GRPS：暫停的任務組信息。

6、QRTZ_LOCKS，悲觀鎖發生的記錄信息。

7、QRTZ_FIRED_TRIGGERS，正在運行的觸發器信息。

8、QRTZ_SIMPLE_TRIGGERS，簡單的出發器詳細信息。

9、QRTZ_BLOB_TRIGGERS,觸發器存為二進制大對象類型(用于Quartz用戶自己觸發數據庫定制自己的觸發器，然而JobStore不明白怎么存放實例的時候)。

.net程序配置quartz數據庫參數

//1.首先創建一個作業調度池var properties = new NameValueCollection();//存儲類型properties["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz";//表明前綴properties["quartz.jobStore.tablePrefix"] = "QRTZ_";//驅動類型properties["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.SqlServerDelegate, Quartz"; //數據源名稱properties["quartz.jobStore.dataSource"] = "myDS";//連接字符串properties["quartz.dataSource.myDS.connectionString"] = Config.QuartzConnStr;//sqlserver版本properties["quartz.dataSource.myDS.provider"] = "SqlServer-20";//最大鏈接數//properties["quartz.dataSource.myDS.maxConnections"] = "5";// First we must get a reference to a schedulerISchedulerFactory sf = new StdSchedulerFactory(properties);IScheduler sched = sf.GetScheduler();

上面便是創建一個調度器，以及配置與quartz數據庫的詳細參數。有啦數據庫后你會很興奮，直接寫t-sql操作數據庫多么便捷啊，并且所有的任務調度信息都一目了然，這里我要告訴你的事，你不需要直接寫sql語句，quart提供的類庫就能自動對數據庫進行填充，以完成對任務調度的管理操作。

quartz.net任務調度的各種操作方法

首先我要說下，我前面有一篇文章對quartz.net做個基本的操作描述，這里也只貼代碼，僅供參考。

1、添加任務計劃，并制定要觸發的執行類

#region 檢查是否存在if (IsExistJob(m.JobGroupName, m.JobName)){return false;}#endregion#region 添加任務計劃if (m.StarTime == null){m.StarTime = DateTime.Now;}DateTimeOffset starRunTime = DateBuilder.NextGivenSecondDate(m.StarTime, 1);if (m.EndTime == null){m.EndTime = DateTime.MaxValue.AddDays(-1);}DateTimeOffset endRunTime = DateBuilder.NextGivenSecondDate(m.EndTime, 1);scheduler = GetScheduler();IJobDetail job = JobBuilder.Create<QuartzFunction>().WithIdentity(m.JobName, m.JobGroupName).WithDescription(m.JobDescribe).Build();ICronTrigger trigger = (ICronTrigger)TriggerBuilder.Create().StartAt(starRunTime).EndAt(endRunTime).WithIdentity(m.JobName, m.JobGroupName).WithCronSchedule(m.CronStr).WithDescription(m.JobDescribe).Build();scheduler.ScheduleJob(job, trigger);scheduler.Start();#endregion#region 關聯運行接口var api = new A_RunJobTriggerEntity();api.ApiCode = m.ApiCode;api.ApiType = m.ApiType;api.ApiUrl = m.ApiUrl;api.AppID = m.AppID;api.CreateTime = DateTime.Now;api.JobDescribe = m.JobDescribe;api.ServiceCode = m.ServiceCode;api.Token = m.Token;api.TriggerGroup = m.JobGroupName;api.TriggerName = m.JobName;new ARunJobRelationManage().Insert(api);#endregion

2、移除執行計劃

scheduler = GetScheduler(); var trigger = new TriggerKey(jobGroup, jobName); scheduler.PauseTrigger(trigger);//停止觸發器 scheduler.UnscheduleJob(trigger); //移除觸發器 var result = scheduler.DeleteJob(JobKey.Create(jobName,jobGroup));

3、暫停指定任務計劃

scheduler = GetScheduler(); scheduler.PauseJob(JobKey.Create(jobName, jobGroup));

4、暫停所有的任務計劃

scheduler = GetScheduler();
scheduler.PauseAll();

5、開啟指定的任務計劃

scheduler = GetScheduler();if (!scheduler.IsStarted){scheduler.Start();}//scheduler.ResumeTrigger(new TriggerKey(jobName, jobGroup)); scheduler.ResumeJob(JobKey.Create(jobName, jobGroup));

6、開啟所有的任務計劃

scheduler = GetScheduler(); if (!scheduler.IsStarted) {scheduler.Start(); } //scheduler.ResumeTrigger(new TriggerKey(jobName, jobGroup)); scheduler.ResumeAll();

7、調度啟動狀態，如果調度的狀態沒有開啟，即便觸發器的狀態為等待執行，執行中，也是無效的。

scheduler = GetScheduler(); if (scheduler.IsStarted) {return "開啟"; } else {return "關閉"; }

8、是否集群?

//是否集群 //properties["quartz.jobStore.clustered"] = "false"; //properties["quartz.scheduler.instanceId"] = "AUTO";

檢驗下結果：

我在兩臺服務器上部署，設置一個任務計劃，每2秒出發一次，2臺機器同時跑，沒有重復執行，且一臺服務器down掉仍可準確無誤的運行，給圖。
