Chapter 9. Scheduling Red Hat Satellite Administrative Tasks
Red Hat Satellite allows organization administrators to regularly perform long-term operations using the
taskomatic service. These operations are segregated into individual tasks and grouped logically into a bunch that is defined by schedules. You can modify these schedules to execute at specific time intervals. Satellite schedules are used to:
- Remove the administrative burden from the organizational administrator by automating tasks.
- Schedule operational tasks for time frames that will not tax the organization's daily network traffic.
Red Hat Satellite provides default schedules that trigger specific task bunches.
