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.

As of January 31, 2014, zBNA will only install on the Windows 7 64-bit platform! It is REQUIRED that any previous version of zBNA is UNINSTALLED due to this latest requirement along with the upgrade to the CPS Java Runtime Environment v7, which is packaged with the tool!

zBNA requires an independent version of the IBM CPS Java Runtime Environment v7 64-bit, which is packaged with the tool.

Please uninstall any previous zBNA package before installing the one above.

Obtain the CP3KEXTR program
CP3KEXTR runs on a System z processor under z/OS. It reads the SMF records to produce an Enterprise Data File (.edf) that contains the SMF Type 70's data and a (.dat) file, which contains the Type 14, 15, 30 and 42 data as input to zBNA.

Access the CP3KEXTR materials.

  • The ability to generate CSV output has also been added to the File menu on the “Job Dataset Report”, “Top 10 Data Sets”, and “Life of a Dataset” panels.
  • Updated the CSV output to contain periods for decimals even in countries where it is a comma so that the CSV can be parsed.

V1.3.0 (12/31/2013)
IBM zEnterprise Data Compression (zEDC) support is implemented. SMF Record Types 14 and 15 are required. Invoke the function using the zEDC: Compression menu on the main zBNA panel. Use the CP3KEXTR program dated 12/12/13 or later.
