KURSINHALT
Kursziele This classroom course discusses catalog management and availability issues of Integrated Catalog Facility (ICF) catalogs in the z/OS and OS/390 environments. Parallel sysplex considerations are examined, and the influence of the Storage Management Subsystem (SMS) on catalogs is discussed. A comparison of catalog caching techniques is analyzed. The course compares the efficiency of two catalog sharing modes: VSAM Volume Data Set (VVDS) Mode and Enhanced Catalog Sharing (ECS) Mode.
Operational examples using a number of IDCAMS commands, such as REPRO, EXPORT, IMPORT, EXPORT DISCONNECT, IMPORT CONNECT, and ALTER are provided and discussed. The course addresses the structures (catalog, VVDS, and VTOC) involved in the ICF environment. Emphasis is placed on systematic error diagnosis, recovery, and backup procedures. Sizing and performance considerations are also introduced.
