DFSMS Implementation


Course Description


Overview

This course provides the skills required to plan and implement Data Facility Storage Management Subsystem (DFSMS). A step-by-step implementation strategy, emphasizing coexistence considerations, is reinforced by hands-on labs. In the hands-on labs, students will be creating constructs as well as coding ACS routines. This milestone approach includes managing temporary and permanent data sets. The course also discusses exploitation of functions provided by DFSMS as the installation evolves to the DFSMS environment.  

Audience

This is an intermediate course is for personnel responsible for developing and implementing effective storage management techniques using DFSMS.

Prerequisites

You should take the following courses or quivalent knowledge may be substituted for these courses.
  • An Introduction to Data Storage Subsystems (SS05G)
  • Storage Management Fundamentals (SS06G) or Storage Management Fundamentals (SK06G)
It is recommended that the student have programming experience which will aid in the writing of the ACS routines.
