This advanced, three-day course is designed, written and presented by specialist RACF consultants.<br>It provides a detailed insight into the technical architecture of RACF and z/OS for z/OS Systems Programmers. The course describes and explains how RACF is implemented and how it can be customised using standard RACF facilities.<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.
RACF for z/OS Systems Programmers
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.
- describe the RACF architecture, its components and facilities
- customise RACF to meet the requirements of their organisation and its environment
- describe how RACF interacts with USS, DB2 for z/OS and CICS
- describe and use all of the RACF Utilities, using JCL and REXX
- 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.
