Application Upgrade
An application upgrade is a major change to an installed application.
Typically, an upgrade changes the physical architecture of the application. For example, an upgrade might add new user accounts, tables, and packages, or alter the definitions of existing objects.
To upgrade the application, you must specify the following in the ALTER
PLUGGABLE DATABASE APPLICATION statement:
- Name of the application
- Old application version number
- New application version number
During an application upgrade, the application remains available. To make this availability possible, Oracle Database clones the application root.
The following figure gives an overview of the application upgrade process.
