RACF for z/OS Systems Programmers


This advanced three-day course, designed, written and presented by specialist RACF consultants, specifically focuses on RACF from a Systems Programmer's perspective.
The course provides a uniquely detailed insight into the technical architecture of RACF and RACF's relationship to z/OS. It describes and explains how RACF is implemented, and how it can be customised using standard RACF facilities.

Extensive hands-on practicals accompany the theory sessions, with each student having their own RACF system to customize.

This course is also available for exclusive one-company presentations, and for live presentation live over the Internet, via RSM's Virtual Classroom Environment service.

The next step

Do you need to know more about RACF and how it works with other systems and services?
For TCP/IP the ideal course is TCP/IP Security in a z/OS Environment using Policy Agent & RACF,
for Db2 you should attend Db2 for z/OS: Using RACF
For UNIX System Services attend RACF Security in a UNIX System Services Environment
For IBM MQ attend Using RACF with IBM MQ
For WebSphere attend Using RACF with WebSphere and Security for WebSphere Applications
For CICS attend Using RACF with CICS

What is a 'Virtual Classroom Environment'?

 

What do I need?

  • webcam
  • headphones with microphone
  • sufficient bandwidth, at least 1.5 Mb/s in each direction.

What you will learn

On successful completion of this course you will be able to:

  • describe the RACF architecture, its components and facilities
  • customise RACF to meet the requirements of their organisation and its environment
  • describe and use all of the RACF Utilities, using JCL and REXX/CLIST
  • identify how the operation of RACF changes when running in a parallel sysplex
  • describe and explain the IPL process and the security issues associated with facilities such as APF, PPT, System Exits and Linklist
  • describe the components of the RACF database.

Who Should Attend

The course is suitable for all experienced Systems Programmers and experienced RACF Administrators who need to understand the technical aspects of RACF.

Prerequisites

Attendees should have a full understanding of RACF at a conceptual level and be familiar with all of the RACF commands and how they are utilised. This can be achieved by attending the courses RACF Administration & Auditing and Advanced RACF Administration.
