One of the best things about Obsidian Scheduler is how quick and easy it is to get it running jobs. With other tools, you might have to set aside an afternoon to get it going, but with Obsidian, trust me, it won’t take long at all. To show you how easy it really is, I’m … Read more
We’ve all worked on projects that required us to do very basic tasks at periodic intervals. Perhaps we chose a basic ScheduledThreadPoolExecutor. If we’re already using Spring, maybe we tried their TaskExecutor/TaskScheduler support. But once we encounter any number of situations such as an increased quantity of tasks, new interdependencies between tasks, unexpected problems in … Read more
The use of Spring framework has woven its way into a large percentage of Java projects of all sorts. It has grown well beyond a dependency injection framework to a large interconnected technology stack providing “plumbing” in a large number of areas. Since it’s so often a part of our lives, we’ll discuss Obsidian’s support … Read more
A lot of Obsidian users write custom jobs in Java and leverage their existing codebase to performs things like file archive or file transfer right inside the job. While it’s great to reuse that existing code you have, sometimes users end up implementing the same logic in multiple jobs, which isn’t ideal, since it means … Read more
When we began development on Obsidian Scheduler, one of its key objectives was transparency. Quoting my own post, transparent means letting us know what is going on. We want to have available to us information such as when was the job scheduled to run, when did it start, when did it complete, which host ran … Read more
In this post I’m going to cover how to do job chaining in Quartz versus Obsidian Scheduler. Both are Java job schedulers, but they have different approaches so I thought I’d highlight them here and give some guidance to users using both options. It’s very common when using a job scheduler to need to chain … Read more
Getting your program code to the point that it satisfies the functional requirements provided is a milestone for developers, one that hopefully brings satisfaction and a sense of accomplishment. If that code must be executed on a schedule perhaps for multiple uses with custom schedules and configurable parameters, this can mean a whole new set … Read more
Job scheduling is used on many software projects to enable both internal jobs and third-party integration. Clustering can provide a huge boost to reliability by providing fail-over and load-sharing. I believe that clustering should be implemented for reliability on just about all software projects, so I’ve decided to outline how to go about doing that … Read more
