1 Overview of Applications in an Application Container

• Managing Applications in an Application Container
  In an application container, an application is the named, versioned set of application common objects stored in the application root. In this context, “application” means “application back-end.” Application common objects include user accounts, tables, PL/SQL packages, and so on. An application can be shared with the application PDBs that belong to the application root.
• Application Maintenance
  Application maintenance refers to installing, uninstalling, upgrading, or patching an application.
