zPCR is a productivity tool designed to provide capacity sizing insights for IBM System z processors. It can help accurately estimate the capacity sizing impact from configuring System z processors. Capacity results are based on IBM’s LSPR data. zPCR is available as a free download available from IBM. This session provides an introduction to the zPCR capabilities to help estimate the impact of capacity sizing challenges, but will utilize the latest version (V7) for z196 / z114 support including the Advanced Functions. It will utilize z196 processor sizing examples to demonstrate its capabilities. This session is intended for someone new to capacity sizing/planning with no zPCR experience or for the experienced person who has never used zPCR. A suggested pre-req for the inexperienced zPCR user is to run Exercise 1 under Education - zPCR Exercises (Exercise Book) on the zPCR site http://www.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/PRS1381. This session is a pre-req for Part 2.
