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

But Obsidian does so in a way that is painless and non-invasive. In fact, you don’t have to do anything. Load balancing and fault tolerance are built into each instance of Obsidian Scheduler whether … Read more
When we started working on our Obsidian Scheduler, one of the primary motivations was to give our clients full control over the configuration of their server runtime and total control over job configuration, including schedule, state, parameterization, etc. More than just full control, we wanted the configuration of said items to take effect immediately across … Read more
