Abstract
IBM Z Batch Network Analyzer (IBM zBNA) is a no charge, "as is", PC-based productivity tool designed to understand the batch window and estimate the CPU upgrade effect by performing "what if" analyses. Use IBM zBNA to evaluate the impact of new technology exploitation such as zEDC, DFSMS Encryption, zHyperLink, and DFSORT IBM Z Sort. IBM zBNA provides powerful, graphic demonstration of the z/OS batch window, which can be automatically captured in a report file using the Named Favorites feature.

Obtain the CP3KEXTR program
CP3KEXTR runs on an IBM zSystems processor under z/OS. It reads the SMF records to produce an Enterprise Data File (EDF) that contains the SMF Type 70 - 78 and 113 data and a (.dat) file, which contains the Type 14, 15, 16, 30 (4) (5), 42 (6) data as input to IBM zBNA.
