Java Quartz作业由每个群集计算机同时执行多次，而不是由一台计算机为整个群集执行一次
目标： *让Job1每10分钟为三节点群集运行一次，让Job2每5分钟为同一群集运行一次。每个作业生成一封电子邮件；所以在上午10:55我应该只收到来自集群的一封Job2电子邮件，在上午11:00我应该收到来自集群的一封Job1电子邮件和一封Job2电子邮件，在上午11:05我应该只收到来自集群的一封Job2电子邮件，以此类推 问题： *在群集中的每个节点上，Job1每10分钟运行多次，Job2也是如此（每5分钟除外）。这就导致了很多很多不止一两封的电子邮件 配置： *三节点linux集群 *每台机器的NTP配置和时间同步 *甲骨文数据库 *Quartz v2.2.0（群集模式） *通过CronTrigger配置的作业 *每个节点都有一个运行在其上的相同独立Java应用程序的实例，Java应用程序以集群模式实例化quartz调度器的一个实例。 *quartz.properties文件在每台机器上都是相同的 我已经调查了所有明显的潜在原因，但没有任何解释或解决办法。我甚至试着在工作中插入一个人工的10秒睡眠指导，以确保它不会在一秒钟内完成。请在下面查找相关工件（quartz.properties和日志输出）。任何帮助都将不胜感激 工件#1:Java Quartz作业由每个群集计算机同时执行多次，而不是由一台计算机为整个群集执行一次,java,oracle,cluster-computing,quartz-scheduler,Java,Oracle,Cluster Computing,Quartz Scheduler,目标： *让Job1每10分钟为三节点群集运行一次，让Job2每5分钟为同一群集运行一次。每个作业生成一封电子邮件；所以在上午10:55我应该只收到来自集群的一封Job2电子邮件，在上午11:00我应该收到来自集群的一封Job1电子邮件和一封Job2电子邮件，在上午11:05我应该只收到来自集群的一封Job2电子邮件，以此类推 问题： *在群集中的每个节点上，Job1每10分钟运行多次，Job2也是如此（每5分钟除外）。这就导致了很多很多不止一两封的电子邮件 配置： *三节点linux集群 *每

OP给出了以下答案 问题是，我使用具有唯一组id（调度程序id）的标识定义quartz作业，而不是集群中所有主机共用的组id。由于调度程序id对于主机是唯一的，因此群集中的每个主机都会使用完全限定的作业名称groupId.jobName查看该作业是否已经存在，并且肯定会发现它没有存在，因此它会在启动期间创建一个新的Job1和Job2实例。如果没有Java中的显式请求或Oracle中的手动sql语句，quartz作业/触发器永远不会过期或清除。因此，随着时间的推移，实例将逐渐增多，而不是运行Job1和Job2的单个实例，它将运行随着时间的推移创建的每个作业的所有实例（因此会出现多次执行和多次电子邮件警报） 解决方案是，在定义作业标识时，我将schedulerId替换为静态字符串，如“MyQuartzJobs” 基本上，我更改了以下一行Java代码：
JobDetail job =
newJob(Job1.class).withIdentity(JOB1_JOB_NAME, uniqueSchedulerId)
.withDescription(JOB1_DESC + " created [" + new Date() + "]")
.storeDurably(false)
.requestRecovery(false)
.build();
JobDetail job =
newJob(Job1.class).withIdentity(JOB1_JOB_NAME, "MyQuartzJobs")
.withDescription(JOB1_DESC + " created [" + new Date() + "]")
.storeDurably(false)
.requestRecovery(false)
.build();
谢谢，但不幸的是，这些问题解决的是另一个问题。
