This hands-on course describes and explains the access method concepts in MVS and the structure and design of VSAM files. It teaches how to create VSAM files using the utility Access Method Services (AMS), both from a functional as well as a performance point of view.<br>Additionally, it provides the Systems Programmer and Operational Analyst with information on the structure of ICF catalogs and the related VTOC and Index VTOC.<br>Online exercises provide experience in creating, accessing and managing VSAM files. Attendees will create and use clusters, alternate indexes and paths.<br><br>This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.

Familiarity with basic z/OS principles and a working knowledge of TSO/ISPF and JCL.

  • describe and explain the concepts of the z/OS access methods
  • analyse the structure of the RRDS, ESDS, KSDS and LDS data sets
  • use the Access Method Services utility program IDCAMS to define, load, backup, monitor and manipulate VSAM data sets with particular emphasis on the KSDS file type
  • develop guidelines for optimised allocation of VSAM files for use at their installation
  • identify performance related issues in the batch and online environments that can be found when using the KSDS file type.
