Planning for Catalog Recovery

z/OS DFSMS Managing Catalogs
SC23-6853-00

To recover a catalog, the ICFRU needs three inputs:
  • An IDCAMS EXPORT copy of the catalog
  • The SMF data from all systems accessing the catalog
  • Parameters describing the needed recovery action
Correct recovery requires that adequate records be kept for the catalog backup data sets and for the SMF dump data sets. It must be possible to:
  1. Determine the date and time of the last valid catalog backup
  2. Identify and locate the catalog backup data set
  3. Identify and locate the SMF dump data sets covering the period between backup and failure
