SMFPRMxx Parameters - Which Can Help; Which Can Hurt
Project and Program: MVS
, MVS Performance
, SHARE in Orlando 2015
Every installation depends on their SMF data, and the collection of that data is controlled by the SMFPRMxx member of SYS1.PARMLIB. Most people set the parameters for SMFPRMxx once and never look back. But times change, and some of the old values may actually be hurting you now. And there are many parameters that you probably don't even know exist, but they can significantly increase your performance. Cheryl and Frank will provide their recommendations for best practices when setting these parameters.-Cheryl Watson-Watson & Walker, Inc.; Frank Kyne-Watson & Walker, Inc.
