How Event-Based Scheduling Works
An enterprise job scheduler that includes event-based scheduling options maximizes your resources by uniting your disparate platforms and their respective job schedules and critical business applications and allowing them to become reactive with one another. A file transfer or report completion could trigger Job A. Then from there, Job A’s completion immediately triggers Job B, which could trigger Job C.
This creates a holistic job schedule that coordinates—and therefore makes the most of—the resources you already have in place.
Benefits of Event-Based Scheduling
- You have the most current data and files in your workflows
- You can cut the built-in slack time between jobs from your schedule, meaning everything runs more efficiently
- You get visibility into every job running
- If a job fails, the process will halt, and you’ll get an alert to fix the problem before another job runs with incorrect or incomplete data.
Types of Job Triggers
JAMS event-based scheduling has built-in triggers which enable users to execute processes on any operating system based upon files being created, modified or deleted.
JAMS can check exit status and determine the appropriate job to trigger based on conditional flows. JAMS event-based job scheduling allows for jobs to have expected run times so that they can be monitored. Alerts can even be triggered to the appropriate person to notify him/her that a job is waiting for that person to release a file.
Alerts can be triggered when an expected event does not occur within a specified time window. With JAMS you can, as an example, alert a vendor or supplier that the system is waiting for their action or a file.
Multiple triggers can be set on jobs so that jobs are triggered based on events, a specific date and time, or even from previous jobs that have failed or succeeded. With JAMS sequences, users can create workflows that depict the dependencies that exist between various processes that are being managed through JAMS.
JAMS event-based job scheduling can also interrogate data by using JAMS Variables and allow specific data to be used as an alternative approach to an event based job trigger. JAMS Variables can be used between jobs so that data is passed throughout the workload.
Event-Based Scheduling vs. Time-Based Scheduling
The most common ways to set your job schedule is event-based and time-based scheduling. Time-based scheduling is a simple way to schedule jobs by designating a time for your process to run. However, event-based scheduling provides a more robust way to streamline your workflows with greater reactivity. Instead of letting your processes sit idle until a set time with time-based scheduling, event-based scheduling allows jobs to begin immediately after another event or process has occurred. This ensures that processes complete in the right order to avoid complications and problems with your IT workflows.
Now, we’re leveraging file triggers. As soon as something happens in the database, it writes a file to the server. JAMS sees the file and it kicks off another job in real-time.
