石英触发器已成为过去

Question

我有 750 个 Quartz 作业，每个作业有 1 个触发器。

转储触发器数据显示下一次触发时间是过去的时间。转储来自 15:55 Berlin/Europe 时区。

nextfire 时间是错误的还是 Quartz 因作业过多而过载？

Answer 1

我发现 quartz 默认配置为只有 10 个运行作业。我将其更改为 200，现在我碰到的下一堵墙是 oracle 不喜欢同时建立那么多连接。

SchedulerFactoryBean quartzScheduler = new SchedulerFactoryBean();
quartzScheduler.setSchedulerName("rm-quartz-scheduler");

Properties props = new Properties();

// Thread pooling
props.put("org.quartz.threadPool.class", org.quartz.simpl.SimpleThreadPool.class.getName());
props.put("org.quartz.threadPool.threadCount", "200");
props.put("org.quartz.threadPool.threadPriority", "5");

quartzScheduler.setQuartzProperties(props);

您可以通过指定

来控制与数据库的连接数

org.quartz.dataSource.myDS.maxConnections = 5

参考此处获取示例配置 JDBC-JobStore Configuration
