When you have developed a keyword string describing the DFSMSdfp software failure, you are ready to search the IBM® software database, using the keyword string as a search argument.
Each keyword describes one aspect of a program failure. Specifying the component identifier keyword, together with the type-of-failure keyword, as a search argument, detects all APARs for that component with that type-of-failure. The more precisely you describe the failure with additional keywords, the more selective the resulting search is, yielding fewer problem descriptions for you to review.
Recommendation: For the catalog-related failures, you should construct two keyword strings because a problem could exist in a module that services catalogs. The first string should specify the ICFCAT keyword for the catalog, and the second should specify the VSAMCAT keyword for the catalog.
