Virtual Storage Access Method: Performance, Design and Fine Tuning

Virtual Storage Access Method (VSAM) is a versatile access method for batch and on-line applications in the IBM mainframe operating systems environment. This book tackles the problems users have long had with VSAM - fine tuning it. Emphasizing the use of VSAM in actual work environments, Ranade explains how to adapt VSAM, design new systems and fine tune existing systems for better performance, without spending more money. This second edition now includes more performance-related information on IBM's new disk drives including cache controllers, effect of SMS, data spaces and hyperspaces on VSAM, ESA and VSAM and a new chapter containing tips and hints.
