SMS Implementation and Control

Audience

This course is intended for all those who may be concerned with planning for, implementing, or managing system-managed storage in an installation. As such it is suitable for System Programmers, Storage Administrators and all those who share with them the management of the installation's data.

Prerequisites

Delegates should already have attended our z/OS for Beginners and Storage Management Fundamentals courses or have a similar level of knowledge or experience.

Duration

3 days. Hands on.

Course Objectives

This course will enable the participant to take full control of an SMS implementation project within their installation, and/or be able to maintain a running SMS installation to best effect. It concentrates on the system management of data stored on DASD.
On completion of this course the delegate will be able to:

• List the areas in which DFSMS/MVS benefits the installation.
• Explain the overall concept of system-managed storage.
• List the control data sets required for DFSMS/MVS
• List the SMS constructs and their purpose
• List the members of SYS1.PARMLIB related to system-managed storage.
• Create an Implementation Planning document for DFSMS/MVS.
• Create the control data sets and populate the Source Control Data Set with: Data Classes, Storage Classes, Management Classes, Storage Groups.
• Plan and code automatic class selection routines to implement the installation’s data management policies.
• Bring about the initialisation of SMS both manually and automatically.
• Control the SMS address space and working environment by means of system commands.
• Explain the benefits of: Concurrent Copy, Sequential Data Striping, Dynamic Cache Management Enhanced.
