To apply patches to Microsoft SQL Server databases in an NDB environment, the administrator should follow a structured process:
Create a new software profile version: Download the latest cumulative update (CU) or patch from Microsoft and use it to create a new version of the existing SQL Server Software Profile in NDB. This ensures the patch is integrated into NDB’s management framework.
Publish the updated software profile: Promote the new version to "Published" status, making it available for use across the environment.
Apply the update: Navigate to the "Database VM Menu" for each database server, select the updated software profile, and apply the patch. This automates the patching process while maintaining database consistency and allowing rollback if needed.
Other options are incorrect or incomplete:
A. Create a Maintenance window schedule and associate the SQL server with that maintenance window in the Database VM Menu: Maintenance windows manage downtime, not patch application for databases.
B. Apply the patch to the database VM then create a new software profile using that updated VM as the source: This manual approach bypasses NDB’s structured patching and lacks version control.
C. Apply the patch to the database VM, then create a new software profile version using that updated database VM as the source, publish the updated software profile then apply that patch under the database VM Menu for each database server: This is overly complex and risky, as manually patching a VM first can lead to inconsistencies.
Thus, the verified answer is D, aligning with NDB’s best practices for database patching.
