DB Servers Hotfixes

DB Servers Hotfixes best practices report by SPDocKit determines whether all SQL servers supporting the SharePoint farm are running on the same patch level.

Issue description

A SharePoint farm may utilize one or more SQL servers in various configurations to store configuration, content, and service application databases. This check determines whether all SQL servers supporting the SharePoint farm are running on the same patch level.

Explanation

All components in a SharePoint environment should be on the same patch level in order to provide maximum compatibility, stability, and supportability. This also applies to SQL servers.

Solution

Check all SQL servers in the SharePoint environment. Make sure that all SQL servers are running on the same patch level and that they are running on the minimum required patch level to support the SharePoint version you are running. In addition, verify that all servers are running the same Windows Server hotfixes.

To verify installed Windows and SQL Server updates, start Control Panel, go to Programs > Programs and Features and click View installed updates.
