If you change a window when it is currently open, the change does not take effect until the next time the window opens. This window runs for one hour daily between 5 a. The window continues to exist but no longer runs automated maintenance tasks. Any other Oracle Scheduler jobs assigned to this window continue to run as usual. This subplan divides its portion of total resource allocation equally among the maintenance tasks.

Note that as with any resource plan, the portion of an allocation that is not used by a consumer group or subplan is available for other consumer groups or subplans. By default there are seven predefined maintenance windows, each one representing a day of the week.

The list of predefined maintenance windows is given in Table Table Predefined Maintenance Windows. Table displays information about database dictionary views for automated maintenance tasks:. Contains information about currently running Scheduler jobs created for automated maintenance tasks. It provides information about some objects targeted by those jobs, as well as some additional statistics from previous instantiations of the same task. Some of this additional data is taken from generic Scheduler views.

Lists the history of automated maintenance task job runs. The system restarts a suspended maintenance task during the next idle period; however, the system won't suspend any task marked as critical. Instead, the system allows a critical task to complete, regardless of user action.

Due to the nature of scheduling, some scheduled tasks may not finish: perhaps there are too many scheduled events to fit into the 1-hour maintenance window, or maybe the computer was simply not turned on. In such cases, you can define a task with a deadline. A deadline is defined as a recurring timeframe in which the system must successfully perform the task at least once. If a task misses a deadline, then the maintenance scheduler will continue to attempt to execute the task during the maintenance window.

Further, the scheduler will not limit itself to the regular 1-hour time limit. Instead, the scheduler extends the duration of the maintenance window in order to complete the delayed task. Once the system completes the task even with a failure error code , the attempt is considered successful. After a successful attempt, the scheduler resets to the regular maintenance schedule, and will attempt the task during the next period.

On Windows 7, a maintenance task runs exclusively during maintenance hour , defaulting to 3 AM, and configurable via Group Policy. The machine would wake up from standby, run maintenance tasks, and go back to sleep. This daily session was limited to a maximum duration of 1 hour per attempt. This would allow the system to perform maintenance daily, starting at 3 AM by default. Note that the user may re-schedule the time that the maintenance is triggered by configuring these settings.

With the advent of laptops, and the heavy focus on battery life, machines are no longer configured to allow S3 wakeup in most circumstances, and generally Doze-To-S4 hibernate as soon as possible, to save battery. So based on how your machines and your tasks are configured, the daily wakeup behavior may not occur today as expected because of this new configuration.
