Time elements are the building blocks of a schedule. Before you can create a scheduled job you must create at least one time element.
Table 31 on page 102describes the components of a time element.
“Creating a scheduled job” on page 96describes how to create a scheduled job by using the available time elements.
Create a new time element
To create a new time element:
1. On the Schedules tab, in the Time Elements section, click the Add a New Time Elementicon.
The Create a New Time Element wizard launches.
2. Select one of the recurrence options.
Table 32 on page 103describes the options.
Table 31 Components of a time element Component Description
Recurrence The calendar cycle that provides the framework for the schedule. This can be daily, weekly, monthly, yearly, weekends, or weekdays.
Wake-up interval Time interval on which the task is started. The task is started at each wake-up interval during the runtime. However, if the task is already running from a previous wake-up, additional processes are not started.
Note: The wake-up interval is determined based on the host’s internal clock, not the last start or finish of the job. For example, a 15 minute wake-up interval with a daily recurrence would check if the job is running and start it if is not at: midnight, 12:15 A.M., 12:30 A.M., 12:45 A.M., and so forth.
Start time Beginning of the time period included in a time element.
End time End of the time period included in a time element.
3. Click Next.
The fields on the wizard's second screen change depending upon the recurrence option selected.

One Specific Time To complete a time element that uses the One Specific Time recurrence option:

This is the one time at which the time element starts the job running.
