When a new security patch is released for the Oracle Database software on a BaseDB VM system, what is the recommended approach for applying it in a production environment?
A.
Immediately apply the patch directly to the production database during off-peak hours to minimize potential security vulnerabilities.
B.
Download the patch and apply it to a non-production environment that mirrors the production environment for testing before applying it to production.
C.
Wait for Oracle Cloud Infrastructure to automatically apply the security patch to all BaseDB VM systems.
D.
Apply the patch to a production standby database (if one exists) and then failover to the patched standby.
B. Testing patches in a non-production environment:
Critical to ensure that the patch does not introduce performance issues or compatibility problems.
Best Practice:Apply the patch to astaging environmentthat mirrors production, validate stability, and then proceed to production.
Minimizes the risk of unplanned downtime or disruptions.
Why the other options are incorrect:
A. Immediate application in production:Risky as untested patches might cause outages.
C. Automatic patching by OCI:OCI does not automatically apply database patches; the customer must manage this.
D. Patching the standby and failing over:While a good strategy when applicable, it still requires prior testing.
