Patching is the process of copying a small collection of files over an existing instance (also referred to as an "in-place installation"). A patch is normally associated with a particular version of an Oracle product and involves updating from one minor version of the product to a newer minor version of the same product. A patch set is a single patch that contains a collection of patches designed to be applied together.
If you plan to install any Oracle Real-Time Decisions patch set, see Oracle Fusion Middleware Patching Guide.
