This manual guides you through the process of planning and executing database upgrades on the Oracle Database. In addition, this manual provides information about compatibility, about upgrading applications to the new Oracle Database 10g release, and about important changes in the new release, such as initialization parameter changes and data dictionary changes.
Oracle Database Upgrade Guide contains information that describes the features and functionality of the Oracle Database (also known as the standard edition) and the Oracle Database Enterprise Edition products. The Oracle Database and the 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 Real Application Clusters option.
See Also:Oracle Database New Features for information about the differences between the Oracle Database and the Oracle Database Enterprise Edition and the features and options that are available to you.
