Quartz.NET学习系列(十一)--- Quartz.NET持久化及客户端服务器模式

持久化

        Quartz.NET如果不进行数据库相关配置，则默认的执行模式为内存模式，优点是执行速度快，确定就是数据无法存储，宕机了需要重新开始。

        持久化只需要做如下配置（以SQLServer为例）

            NameValueCollection properties = new NameValueCollection();
            //存储类型
            properties["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz";
            //表明前缀
            properties["quartz.jobStore.tablePrefix"] = "QRTZ_";
            //驱动类型
            properties["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.SqlServerDelegate, Quartz";
            //数据源名称
            properties["quartz.jobStore.dataSource"] = "myDS";
            //连接字符串
            properties["quartz.dataSource.myDS.connectionString"] = @"Data Source=(local);Initial Catalog=quartz;User ID=sa;Password=123";
            //sqlserver版本
            properties["quartz.dataSource.myDS.provider"] = "SqlServer-20";

        服务器代码例子：

        public class RemoteServerExample 
	{
		public static void Run()
		{
			ILog log = LogManager.GetLogger(typeof(RemoteServerExample));
			
                        NameValueCollection properties = new NameValueCollection();
                        <span style="font-family: Arial, Helvetica, sans-serif;">properties["quartz.scheduler.instanceName"] = "RemoteServer";</span>

                        properties["quartz.threadPool.type"] = "Quartz.Simpl.SimpleThreadPool, Quartz";
                        properties["quartz.threadPool.threadCount"] = "5";
                        properties["quartz.threadPool.threadPriority"] = "Normal";

                        // 设置服务器
                        properties["quartz.scheduler.exporter.type"] = "Quartz.Simpl.RemotingSchedulerExporter, Quartz";
                        properties["quartz.scheduler.exporter.port"] = "555";
                        properties["quartz.scheduler.exporter.bindName"] = "QuartzScheduler";
                        properties["quartz.scheduler.exporter.channelType"] = "tcp";
                        properties["quartz.scheduler.exporter.channelName"] = "httpQuartz";
                        // 拒绝远程
                        //properties["quartz.scheduler.exporter.rejectRemoteRequests"] = "true";

                        //存储类型
                        properties["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz";
                        //表明前缀
                        properties["quartz.jobStore.tablePrefix"] = "QRTZ_";
                        //驱动类型
                        properties["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.SqlServerDelegate, Quartz";
                        //数据源名称
                        properties["quartz.jobStore.dataSource"] = "myDS";
                        //连接字符串
                        properties["quartz.dataSource.myDS.connectionString"] = @"Data Source=(local);Initial Catalog=quartz;User ID=sa;Password=123";
                        //sqlserver版本
                        properties["quartz.dataSource.myDS.provider"] = "SqlServer-20";

                        ISchedulerFactory sf = new StdSchedulerFactory(properties);
                        IScheduler sched = sf.GetScheduler();
			sched.Start();
			
			log.Info("------- 服务器启动 -----------------");
			Thread.Sleep(TimeSpan.FromMinutes(5));
                        //sched.Shutdown(true);
                        log.Info("------- 服务器关闭 -----------------");
			
			SchedulerMetaData metaData = sched.GetMetaData();
			log.Info("执行次数 " + metaData.NumberOfJobsExecuted );
		}
