You change the maintenance schedule of an Autonomous Container Database from its Details page.
Go to the Details page of the Autonomous Container Database whose maintenance schedule you want to change.
For instructions, see View Details of an Autonomous Container Database.
Click the Edit link in the Maintenance Details field.
On the Edit Automatic Maintenance card, change settings under Configure the automatic maintenance schedule as desired.
Select No preference to permit Oracle to schedule maintenance as needed based on the maintenance schedule of the Autonomous Exadata Infrastructure resource hosting the Autonomous Container Database.
Select Specify a schedule to restrict when Oracle can schedule maintenance.
- Specify the permitted months. You must select at least one month per quarter.
- Specify the week (or weeks) within the selected months.
- Specify the day (or days) of the selected week.
- Specify the 4-hour window (or windows) when maintenance operations can begin.
When specifying a schedule, you should ensure that the schedule you define falls after the schedule of Autonomous Exadata Infrastructure resource hosting the Autonomous Container Database. If the Autonomous Exadata Infrastructure resource has a customized schedule, you can view its schedule by clicking Show Autonomous Exadata Infrastructure maintenance schedule. If the Autonomous Exadata Infrastructure resource doesn't have a customized schedule, its maintenance schedule will be automatically modified so that it precedes the Autonomous Container Database schedule you define.
- When finished, click Save Changes.
