Baseline Libraries and Delta Decks

ChangeMan ZMF recognizes that your software components are a vitally important business asset. It gives you the ability to store your production source components in a structure that works for your organization. Components can be stored in PDS files, PDSE files, CA Librarian files or CA Panvalet files. Components can be segregated by application or by categories, such as batch versus online. Equally, applications can share libraries.

ChangeMan ZMF automatically stores prior versions of components. These versions can be stored as full copies (inherent for load components), or as delta decks. It uses a unique reverse base/delta technique known as stacked reverse deltas. With this technique, the current version of the component is the base, and delta decks are created to backtrack to previous versions.
