Questions tagged [job-scheduling]

A job scheduler is a computer application for controlling unattended background program execution (commonly called batch processing).

Today's job schedulers, often termed workload automation, typically provide a graphical user interface and a single point of control for definition and monitoring of background executions in a distributed network of computers. Increasingly, job schedulers are required to orchestrate the integration of real-time business activities with traditional background IT processing across different operating system platforms and business application environments.
