System-Impacting Virtual Storage Issues: Detection and Diagnosis

Project and Program: MVS, MVS Core Technologies

Tags: Proceedings, 2019, SHARE Pittsburgh 2019

Join z/OS Software Support specialists in their virtual world as they delve into the prevention, detection, and diagnosis of system-impacting virtual storage growth problems.  This presentation will focus on recognizing growth in below-the-bar common storage, as well as in high virtual (above-the-bar) private, shared, and common storage.  Learn what tools are available to safeguard your system and alert you to a potential virtual storage problem BEFORE it leads to system impact. Additionally, VSM's storage management strategy for below-the-bar common storage will be overviewed, setting the stage to perform analysis on a dump of an actual below-the-bar common storage problem.  Dump analysis will focus on effective use of VSM's CSA Tracker report (under IPCS) to quickly identify the source of common storage growth. By the end of the hour, you will feel virtually brilliant!-John C. Shebey-IBM Corporation; Patty Little-IBM Corporation
