"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Blackout temporarily pauses the monitoring of the target, so that event triggers such as "database down" don't fire.  To a site that measures down time, then scheduled maintenance windows are blacked out -- rather than being reported as a violation of the service level agreement (SLA).
Oracle admin use blackouts to prevent data collection during scheduled maintenance or emergency operationsfor users.

Also all jobs submitted  will not be scheduled or run for the duration of the blackout.

Sp button line they get used when DBA does a maintenance.
