VSAM data set design parameters

by D. G. Keehn, J. O. Lacy
A general description of the Virtual Storage Access Method (VSAM) is followed by a qualitative discussion of performance expectations. VSAM data-set design parameters are discussed with respect to performance tradeoffs. Analytic techniques are developed for relating some of the VSAM performance sensitivities to data set design parameters.
