|Oracle® Database Upgrade Guide
11g Release 2 (11.2)
Part Number E17222-04
This manual guides you through the process of planning and executing Oracle Database upgrades. In addition, this manual provides information about compatibility, upgrading applications, and important changes in the new Oracle Database release, such as initialization parameter changes and data dictionary changes.
Oracle Database Upgrade Guide contains information that describes the features and functions of Oracle Database (also known as the standard edition) and Oracle Database Enterprise Edition products. Oracle Database and Oracle Database Enterprise Edition have the same basic features. However, several advanced features are available only with the Enterprise Edition, and some of these are optional. For example, to use application failover, you must have the Enterprise Edition with the Oracle Real Application Clusters option.
See Also:Oracle Database New Features Guide for information about the differences between Oracle Database and Oracle Database Enterprise Edition and the features and options that are available to you.
