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.

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

Schedule

No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested ? Please contact ABIS.

Intended for

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