在特定主机上运行特定的石英作业

Question

I've few quartz jobs that I'm running in clustered mode. Some are IO intensive and some are CPU intensive jobs. What I want to do is run CPU bound jobs on a particular host and run IO bound job on another set of hosts. Is there any configuration where I can whitelist a set of jobs that can run on a particular machine? I don't want to create another set of quartz table do this kind of thing.

Tech: Spring boot, Oracle, Quartz 2.X

Thanks a lot!

Answer 1

I suggest in the Jobstore, just use pauseJob or pauseJobGroup for each jobs for those particular machines.

Or you can also use pause thru SQL

Or thru environment settings, you have a switch there to what jobs you want to get disabled.

Answer 2

The way I did this is to create a different scheduler instance depending on the property passed in JVM startup parameter. I used Spring quartz integration and here is the sample code for that. Most important part is setting of auto startup to false for the scheduler that should not run. This way I was able to create different scheduler but only started the ones that were configured in properties.

 @Bean
public SchedulerFactoryBean schedulerFactory(DataSource dataSource, JobFactory jobFactory)
        throws IOException {
    SchedulerFactoryBean factory = new SchedulerFactoryBean();
    factory.setBeanName("myscheduler");
    factory.setDataSource(dataSource);
    factory.setJobFactory(jobFactory);
    factory.setQuartzProperties(getQuartzProperties());
    if (!System.getProperty(SCHEDULER_NAME).contains("myscheduler")) {
        factory.setAutoStartup(false);
    }
    return factory;
}
