Before you start any patch or upgrade process, you should refer to the release notes that apply either to your patch or to the release levels of your upgrade.
For information about upgrading your existing Oracle Real-Time Decisions 184.108.40.206 environment to Oracle Real-Time Decisions 11g, see "Upgrading Oracle Real-Time Decisions" in Oracle Fusion Middleware Upgrade Guide for Oracle Business Intelligence.
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.
