Chapter 9. Data Guard Configuration Patching
Patching demands more from production systems to fix the existing bugs in the software to avoid outages in critical databases even when there are no workarounds available. These patches will be delivered by the development team of Oracle. Some patches come with scripts and some do not.
In this chapter we shall discuss the different types of patches, importance of patching, and how to apply patches on a database with Data Guard configuration, either on physical or logical standby databases.
