Effective in version 10.2.2, you can create incremental applications. An incremental application is an application that you can update by deploying an application patch to update a subset of application objects. The Data Integration Service updates the objects in the patch while other application objects continue running.
If you upgrade to version 10.2.2, existing applications are labeled "full applications." You can continue to create full applications in version 10.2.2, but you cannot convert a full application to an incremental application.
