The document discusses Oracle's Database Fleet Maintenance solution which provides automated software configuration standardization at scale. It detects configuration variations across databases, defines standard software "images", and allows databases to subscribe to these images. Changes are made at the image level and propagated to subscribers, enabling simplified and centralized software updates across the database fleet with reduced downtime. The solution provides complete automation, easy scaling, centralized control, and support for patching and upgrading databases.

Database Fleet Maintenance
• Allows emergency, ad-hoc patching.
• Ad-hoc is more an exception than a norm,
its tracked as ‘Rogue’
• Reconcile the rouge targets either by rolling
the changes to a new version of the image
or override it with the latest version.
