In DLM 2.0 dlm.xml file is no longer used. It is replaced with the Fragment Manager channel as seen running in Luminis IV in the image below. The set of configured fragments is persisted in the uPortal database. The uPortal entity cache is used to convey to other servers in a cluster that fragments have changed and should be loaded. Such changes include not only fragment definition changes but also fragment layout changes and published channel changes where such channels are found in the layouts of one or more fragments. Most items currently configured using the dlm.xml file are visible. For example, precedence is clearly indicated by order in the list. Fragments at the top have highest precedence. The arrow buttons allow for increasing or decreasing precedence in a very straightforward manner. A new feature in DLM 2.0 is depicted by the green lamp indicator next to most of the fragments. Each fragment can be enabled or disabled at any time. Such functionality was only possible in DLM 1.0 by removing the definition from dlm.xml.

The name of each fragment corresponds to the "name" attribute of the <dlm:fragment> element. The delete button is for deleting a fragment. The edit button immediately to the left of the fragment name delete button allows an administrator to change the name and type of the fragment. Note that both pushed and subscribe subscribed fragments appear in the same view in the Fragment Manager. This is important since each type can restrict movement of tabs and hence those tabs may be competing for location in a user's layout. The ordering here with respect to each other clearly shows which will have greater precedence when competing in a user's layout.
