DB2 for z/OS: Using RACF


DB2 for z/OS security has historically been performed using an external security product such as RACF to secure the system, while access to DB2 objects and data was controlled using DB2 internal security.
However now more and more organisations are using RACF to control all aspects of DB2 security - both at the system and data levels.
This intensive, one-day course shows exactly how this may be achieved.

This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.

Objectives

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

  • describe DB2 security
  • understand terminology used with DB2 security
  • use and structure DB2 security tables
  • use primary, secondary, and CURRENT SQLID authorisation IDs used by DB2
  • use SQL to control security using the GRANT and REVOKE statements
  • describe the meaning of explicit, implicit, composite and grouped privileges
  • explain ownership considerations with regard to DB2 objects
  • control DB2 address space and data set authorisation using RACF
  • use RACF to control access to DB2 objects
  • describe the new RACF classes for DB2 objects
  • create RACF profiles for DB2 objects
  • understand the additional considerations when using DB2 in a distributed environment.

Who Should Attend

All DB2 or RACF security administrators wishing to gain further insight into controlling DB2 security using RACF.

Prerequisites

A working knowledge of RACF and an understanding of DB2 for z/OS at a conceptual & terminological level.
