Preparing 12.2 Database Deployments Hosting Oracle RAC Databases for Patching
This topic does not apply to Oracle Cloud Infrastructure or to Oracle Cloud at Customer.
Note:
The following procedure is required only for 12.2 database deployments using Database Classic Cloud Service release 17.2.1 or earlier.
Before you begin
-
Make sure the database deployment has cloud tooling version 17.2.5.1 or later. For more information, see Updating the Cloud Tooling by Using the raccli Utility.
-
Before starting the procedure, you should back up the deployment. For instructions, see Creating an On-Demand Backup.
-
Plan for the following downtime while performing the procedure:
-
Database Clustering with RAC—Both Oracle RAC nodes will be shut down simultaneously while you apply a patch to the database.
-
Database Clustering with RAC and Data Guard Standby—First, both Oracle RAC nodes of the standby database will be shut down simultaneously while you apply a patch to the standby, and then both Oracle RAC nodes of the primary database will be shut down simultaneously while you apply a patch to the primary.
-
Procedure
Apply a “sync-up” patch to your 12.2 database deployment.
-
For Database Clustering with RAC databases, perform the steps in this procedure once.
-
For Database Clustering with RAC and Data Guard Standby databases, perform the steps in this procedure twice: first on your standby database and then on your primary database.
