Determines the amount of time the system will wait before the start of each database server patching operation. Custom action timeout is in minutes and valid value is between 15 to 120 (inclusive). Note: Numbers greater than Number.MAX_SAFE_INTEGER will result in rounding issues.
Days during the week when maintenance should be performed.
The window of hours during the day when maintenance should be performed. The window is a 4 hour slot. Valid values are
If true, enables the configuration of a custom action timeout (waiting period) between database server patching operations.
If true, enables the monthly patching option.
Lead time window allows user to set a lead time to prepare for a down time. The lead time is in weeks and valid value is between 1 to 4. Note: Numbers greater than Number.MAX_SAFE_INTEGER will result in rounding issues.
Months during the year when maintenance should be performed.
Cloud Exadata infrastructure node patching method, either "ROLLING" or "NONROLLING". Default value is ROLLING.
IMPORTANT*: Non-rolling infrastructure patching involves system down time. See [Oracle-Managed Infrastructure Maintenance Updates](https://docs.cloud.oracle.com/iaas/Content/Database/Concepts/examaintenance.htm#Oracle) for more information.
The maintenance window scheduling preference.
If true, skips the release update (RU) for the quarter. You cannot skip two consecutive quarters. An RU skip request will only be honoured if the current version of the Autonomous Container Database is supported for current quarter.
Weeks during the month when maintenance should be performed. Weeks start on the 1st, 8th, 15th, and 22nd days of the month, and have a duration of 7 days. Weeks start and end based on calendar dates, not days of the week. For example, to allow maintenance during the 2nd week of the month (from the 8th day to the 14th day of the month), use the value 2. Maintenance cannot be scheduled for the fifth week of months that contain more than 28 days. Note that this parameter works in conjunction with the daysOfWeek and hoursOfDay parameters to allow you to specify specific days of the week and hours that maintenance will be performed.
