Understanding Your ACS Routines


In the z/OS® environment, the Automatic Class Selection (ACS) routines lie at the heart of dataset creation and use. Every dataset, new or old, SMS managed or not, of whatever format, relies on the ACS routines to assign the proper SMS classes and control dataset use. The ACS Routine language is simple, compact, and deliberately limited in scope, yet many installations suffer from large, unwieldy, confusing ACS Routines containing ancient code which are updated only rarely and with trepidation. 

In this webinar we examine the ACS Routine language itself, the best practices and proper use of the language constructs, ACS testing, and provide some suggestions on how you can improve the ACS routines in your shop.
