Abstract: zBNA is a PC-based productivity tool designed to provide a means of estimating the elapsed time for batch jobs solely based on the differences in CPU speeds for a base processor and a target processor, the number of engines on each system, and system capacities; data sharing is not considered. zBNA provides powerful, graphic demonstration of the z/OS batch window.

Important: Any previous version of zBNA must be uninstalled prior to installing the new version (1.7.0) that supports Java V8. This is necessary in order to preserve Windows Registry integrity with respect to this tool.
