But you cannot really do anything when the whole application/server/scheduler was down. You can increase the number of worker threads by simply customizing the in quartz.properties (default is 10). the job was scheduled with start time in the past (probably a coding error).all worker threads were busy running other jobs (probably with higher priority).In addition to our product website, we’ve discussed Obsidian’s standout features many times here on our blog.Sometimes Quartz is not capable of running your job at the time when you desired. We have a live, interactive demo where you can try out the interface and see first-hand how easy it is to add/change/disable jobs, to monitor all the node activity, disable/enable nodes and even take advantage of advanced schedule configuration such as chaining and sticky nodes. You truly can be up and running the same day you download it. Obsidian Scheduler really is the best choice for your java-based applications. It is feature poor and has high implementation and ongoing utilization costs in terms of time and energy. Insufficient mechanisms for dealing with errors/failures and recoveryĪll this means Quartz is not really a justifiable choice as an enterprise scheduler.No adminstration UI that allows all job scheduling and configuration to be done outside of code.No out of the box support for multiple execution nodes (pooling or clustering).Simply put, Quartz doesn’t meet these basic needs: Quartz also provides an add-on called Quartz Manager, it too needs additional advanced configuration, is a flash app and is incrediby cumbersome and impractical to use. Quartz does provide add-on support for multiple nodes, but it requires additional advanced configuration. No monitoring console for reviewing errors and history, no useful and reasonably searchable logging, no support for multiple execution nodes, no adminstration interface, no alerts or notifications, inflexible and buggy recovery mechansims for failed jobs and missed jobs. Out of the box, it is just a code library for job execution. Quartz is also deficient in its feature set. What happens when you need to make a change to a job’s schedule? Temporarily disable a job? Change the parameters bound to a job? All these require a build/test/deploy cycle which is impractical for any organization. Even in Quartz’ tutorial, it takes 6 lessons to setup a job. Quite the headache for something that was supposed to simply be “execute jobs when you need to”. All this is code you have to write for each job or the equivalent xml configuration. withIntervalInSeconds(40).repeatForever()).build()Īnd then schedule them using Schedule instance from a ScheduleFactory. withIdentity("myTrigger", "group1").startNow().withSchedule(simpleSchedule() You have to write your implementation of the job interface, then you have to construct large xml configuration files or add code to your application to build new instances of JobDetails, Triggers using complex api such as Getting your code to run in a schedule with quartz is anything but straightforward. For any of you that actually have experience with Quartz, this is truly laughable.įirst of all, adding the quartz library to your app does not begin to ready your application to schedule jobs. Quartz’ home page at the time of writing claims that using quartz is a simple 3-step process: Download, add to app, execute jobs when you need to. If you need to schedule jobs in Java, it is fairly common in the industry to use Quartz directly or via Spring integration.
