Quartz Scheduler中的多个作业未根据触发器运行

Question

I have configured a quartz scheduler with 4 different jobs, each triggering every 1 minute. The schedule I have configured is as follows:-

  <schedule> <job> <name>LockMonitor</name> <job-class>background.jobs.LockMonitor</job-class> </job> <trigger> <simple> <name>LockJobTrigger</name> <job-name>LockMonitor</job-name> <repeat-count>-1</repeat-count> <repeat-interval>60000</repeat-interval> </simple> </trigger> <job> <name>LogMonitor</name> <job-class>background.jobs.LogMonitorJob</job-class> </job> <trigger> <simple> <name>LogMonitorTrigger</name> <job-name>LogMonitor</job-name> <repeat-count>-1</repeat-count> <repeat-interval>60000</repeat-interval> </simple> </trigger> <job> <name>ProcessMonitor</name> <job-class>background.jobs.ProcessMonitor</job-class> </job> <trigger> <simple> <name>ProcessMonitorTrigger</name> <job-name>ProcessMonitor</job-name> <repeat-count>-1</repeat-count> <repeat-interval>60000</repeat-interval> </simple> </trigger> <job> <name>HealthCheck</name> <job-class>background.jobs.HealthCheck</job-class> </job> <trigger> <simple> <name>HealthCheckTrigger</name> <job-name>HealthCheck</job-name> <repeat-count>-1</repeat-count> <repeat-interval>60000</repeat-interval> </simple> </trigger> </schedule> 

The problem that I am encountering is that only the 1st and 2nd jobs are getting executed most of the time. The 3rd and 4th jobs - namely ProcessMonitor and HealthCheck are getting executed only once in a while. Can someone help me with this? Is this because I have configured the same time interval for all the jobs? Is there any means by which I can ensure that all the 4 jobs are executed before starting the next set of execution?

I have configured all the jobs as implements StatefulJob

Answer 1

How many threads did you configure? When I keep the number of thread == number of jobs registered to run in the Quartz framework, everything seems to run as expected.
