The Scheduler service provides a generic job scheduling service for System Manager and Avaya Aura® applications. The Scheduler service provides an interface to run a job on demand or on a periodic basis. You can schedule a job to generate an output immediately or set the frequency of the task execution to run on a periodic basis. You can modify the frequency for a periodic job schedule any time. After you define a task or a job, System Manager creates instances of the task, monitors the execution of the task, and updates the status of the task.
