One Nightly per Day

The Scheduler has an additional validation for Nightly tasks named the One Nightly per Day rule. This rule is turned off by default, meaning that if it’s not explicitly set, the Scheduler will not enforce it. If this rule however is explicitly set, the Scheduler will try to ensure that two consecutive Nightly cycles are not run on the same calendar day (based on the time zone set). For example, consider the case where the Nightly cycle is setup with the WEEKLY frequency, and is scheduled to run at 10 am on Sunday and then 7 pm on Monday. If this validation is not enforced, the Scheduler would schedule the Nightly cycle at 10 am and then again at 7 pm on Sunday itself.

In such cases, if this rule is in place, the Scheduler bumps the Nightly Cycle to the same time for the next day. A Notification is also created to signal that the Nightly has been adjusted in adherence to this rule.

Note:

As stated previously, the default is not to enforce this validation. This behavior can be changed by creating the System Option EnsureOneNightlyPerDay and setting it to TRUE on the System Configuration – System Options screen.
