When ICF catalogs were first introduced in the early 1980’s, Integrated Catalog Facility Recovery Unit (ICFRU) was IBM’s recommended tool to recover a damaged catalog. An Access Method Services EXPORT of the broken catalog was required as the starting point for the recovery. Snapshots of catalog records, in the form of SMF records, are applied to the EXPORT to “up-level” the catalog to create a new “recovered” EXPORT copy. ICFRU provides no support for the recovery of a VVDS.This whitepaper discusses the use of SMF data for Integrated Catalog Facility (ICF) catalog recovery and its complexities.

It could be argued that the catalog environment could be expanded to include a discussion including any one of the five major Tape Management Catalogs (TMCs) and/or IBM’s Hierarchical Storage Manager (HSM) offering, but these topics can be discussed in detail in a later white-paper. A catalog allows access to a data set without having to know its physical location. This whitepaper, the first in a series of in-depth technical discussions about ICF Catalog Basics, looks at the catalog BCS, VVDS, and VTOC components and how they are related.
