1 Oracle Fusion Middleware Patching and Upgrade Overview

This book describes the tools available for you to patch your existing Oracle Fusion Middleware Identity and Access Management environment 11g Release 2 (11.1.2.0.0) environment to the latest patch set.

The following topics are covered:

1.1 Installation, Patching, and Upgrade Terminology

This section describes various terms that you should be familiar with before you continue.

1.1.1 Patching

Patching involves copying a small collection of files over an existing 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 11.1.2.0.0 to version 11.1.2.1.0).

A patch set is a single patch that contains a collection of patches designed to be applied together.

1.1.2 Migration

Migration typically involves moving from a third-party (non-Oracle) product to an Oracle product.

It can also be used to refer to moving an existing set of software parameters (for example, an existing configuration or existing domain) from one release to another.

1.1.3 Upgrade

Upgrade involves moving from a previous major version to a new major version. For example, an upgrade would be required to move from Oracle Application Server 10g to Oracle Fusion Middleware 11g.

1.1.4 Installation

Installation is when new software is copied onto your system for use. After the new software is installed, you can patch it or upgrade it as necessary.

1.2 Patching and Upgrade Tools

Table 1-1 provides a brief summary of the patching and upgrade tools, and provides pointers to more detailed information.

1.3 About Database Patches for Oracle Fusion Middleware

This guide provides instructions for applying Oracle Fusion Middleware patches to your existing Oracle Fusion Middleware installations.

However, there are specific cases where you might be instructed to apply an Oracle Database patch to an existing Oracle Fusion Middleware Oracle home. This is because some Oracle Fusion Middleware products include specialized components, such as application programming interfaces (APIs), software libraries, and other software code developed for Oracle Database products.

In these specific cases, you might be referred to Oracle Database patching and installation documentation for more information.

Note that in most cases Oracle Fusion Middleware patches include all necessary software updates. You should apply Database patches only when specifically instructed or if you are experiencing a specific issue that can be resolved by the database patch.
