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 (for example, from version 18.104.22.168 to version 22.214.171.124). A patch set is a single patch that contains a collection of patches designed to be applied together.
If you plan to install the Oracle Real-Time Decisions 126.96.36.199 patch set over an existing 188.8.131.52 instance, see Oracle Fusion Middleware Patching Guide.
