You know about the ACS routines and the SMS constructs, but do you know about all of the additional SMS management controls and switches that IBM has placed in SYS1.PARMLIB? More than 75 different IGDSMSxx keywords control important aspects of allocation, volume selection, RLS, PDSE functions, and much more. In this session we'll examine some of the most significant parameters in IGDSMSxx that have an impact on data set creation and usage and system function, as well as some important others 'hidden' in DEVSUPxx, IGGCATxx, and ALLOCxx and recent changes introduced in z/OS 2.4.-Steve Pryor-DTS Software, LLC
