Schedule a Quarterly Maintenance Update

You can schedule an on-demand maintenance to update RU (Release Update) along with the time-zone file or just the time-zone file for an Autonomous Container Database (ACD). You can also choose to update using an existing custom database software image.
Note

For on-demand maintenance updates with a time-zone file update, the standby ACD will be patched 3 days before the primary ACD in autonomous data guard enabled ACDs.

Required IAM Policies

Procedure

  1. Go to the Details page of the Autonomous Container Database for which you want to schedule a maintenance update.
  2. Under More actions, click the Schedule maintenance button.
  3. Choose the following on the Schedule maintenance dialog that appears.
    Setting Description Notes
    Configure update type

    Custom database software image: Click this tile to schedule an update using an existing custom database software image. You can select a Region, Compartment, and Database version to choose a Custom database software image.

    Release Update (RU): Click this tile to schedule a release update (RU) along with time-zone file update. This tile is disabled if your ACD is already patched to the latest RU.

    Time-zone file update: Click this tile to schedule time-zone file update only.

    Time-zone files can only be updated in a non-rolling configuration method that involves full system downtime.

    If the selected Custom database software image has an updated Time-zone version, the time-zone of the ACD will be updated. Updating the time-zone requires mandatory downtime for the ACD and associated Autonomous Databases. The downtime duration depends on the amount of time-zone sensitive data.

    You cannot select a custom database software image of a previous RU. Selecting the Custom database software image for patching will cancel the current maintenance run if one is scheduled for your ACD.
    Configure maintenance method

    The Rolling method updates the ACD, one node at a time, with no downtime for theAutonomous Databases.

    The Non-rolling method shuts down and updates the ACD in parallel across all nodes. This method minimizes maintenance time but it requires full downtime for the ACD and all associated Autonomous Databases.

    		 
    Enable time-zone update

    Optionally, you can also select Enable time-zone update. Time-zone files can only be updated using the non-rolling configuration method.

    If you configure your maintenance to the rolling method and enable time-zone update, all the RUs that include a time-zone update are applied in the non-rolling method only. Only those RUs without a time-zone update are applied in the rolling method.

    You cannot enable time-zone update if you are scheduling an update using a Custom database software image.
    Schedule start time

    Using the calendar tool, choose a date and time for the maintenance update.

    		  
  4. Click Schedule maintenance.
Note

The maintenance settings selected from the Schedule maintenance dialog apply to the maintenance update scheduled from this dialog only. These changes do not apply to the maintenance preferences defined at the ACD level.
