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.
