How to Update Exadata Database Service in Oracle Cloud to Exadata Image Version 23.x and Oracle Linux 8
(Doc ID 2936828.1)
Last updated on AUGUST 15, 2023
Applies to:
Oracle Database Cloud Exadata Service - Version N/A to N/A [Release 1.0]Oracle Exadata Storage Server Software - Version 23.1.0.0.0 and later
Information in this document applies to any platform.
Goal
The goal of this document is to guide a user of the Exadata Database Service in Oracle Cloud in updating the Exadata System Software on nodes in the VM cluster to Exadata image version 23.x from 22.1/21.2 using a command line patchmgr-based approach.
The preferred approach for updating the Exadata image version is to use the Oracle Cloud Console, but there may be circumstances where the manual approach described in this document is needed, such as the following:
- Updating one node at a time, which may be necessary when customer actions are required on each node before or after the update before proceeding to the next node.
- Updating a subset of nodes at a time.
- Updating all nodes in the VM cluster in a non-rolling manner.
