A complex job is made up of one or more tasks, a schedule, and a set of performance options. At the time that you create the job, you set the schedule (see To Set Job Schedules) and the options (see To Set Job Options). On the other hand, you may create the objects of the tasks either on the fly, as you create the tasks, or before you begin to create the job.
A task needs a profile:
You can create or copy a profile beforehand. See Chapter 9, Profiles
You can use Predefined Profiles. See Chapter 7, System Management Profiles
A task needs a policy:
You can create or copy a policy beforehand. See Chapter 10, Policies
You can use the default Always ask me policy.
A task needs a hostlist:
You can select groups to ensure hosts of similar functionality receive consist jobs. See Chapter 4, Hosts and Groups
You can select one or more hosts (using the Shift or Control keys) from the New Job window.
Users with restricted permissions over groups can select only groups and hosts of their authorized groups.
