Q:

What is Autosys?

Answer

AutoSys is an automated job control system for scheduling, monitoring, and reporting. These jobs can reside on any AutoSys-configured machine that is attached to a network.


 


However, in real business, you need to fire jobs not just based on scheduled time, but also based on events (like an arrival of a file), and, based on the success or failure of other jobs. Autosys is a total job scheduling solution that allows you to define these events, dependencies, time schedules, alerts, etc, making it a complete data center automation tool.
