Scrubbing derived objects and data containers

A reference count of zero means that the derived object has been deleted or overwritten in every view that ever used it. This situation calls for scrubbing: automatic deletion of DO-related information from the VOB.

Scrubbing can remove the derived object from the VOB database, its data container from a VOB storage pool (if the DO had ever been shared), and in some cases its associated CR, as well.

The scrubber utility removes derived objects from a VOB database and data containers from VOB storage pools. The view_scrubber utility removes data containers from the private storage area of the dynamic view. For more information about scrubbing, see the Help for HCL VersionVault.
