IBM z Systems Batch Network Analyzer (zBNA) Tool

Product documentation

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.

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

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 & 113 data and a (.dat) file, which contains the Type 14, 15, 30, 42 data as input to zBNA.

  • Added a new column, Delta DASD Space MB, to the zEDC table to estimate how many MBs won't be stored on disc as a result of converting the dataset to zEDC.
  • Miscellaneous bug fixes.

V1.6.1 (01/30/2015)
Miscellaneous enhancements and bug fixes.

V1.5.1 (12/12/2014)
  • Enhancements made to the “zEDC Top Data Sets” panel include;
  • New graph, Dataset Gigabytes per Hour, has been added.
  • Added a filter function, Graphing Options, to support what gets graphed.
  • A checkbox column has been added to the DSN table allowing data sets to be included or excluded from the graphs.
  • The status bar has been added at the bottom of the table to show how many DSNs (maximum is 1000) there are.
  • A total row has been added for each compression type in the zEDC report.
  • A file is created when zBNA detects an error. The default directory where the file is saved is C:\Users\IBM_ADMIN\AppData\Roaming\zBNA .

V1.5.0 (10/21/2014)
  • The Job Information panel (Step Details) was updated to look as the regular panels. The panel can now be resized.

  • Improvements in load processing to help handle large amounts of data.
  • Fixes to CSV and HTML generation for zEDC
  • Fix to the main table and filters (seconds added where needed)
  • The “zEDC Top Data Sets” panel now shows the estimated I/O Count, I/O time, and CPU Time deltas, if the candidate data set would be compressed with zEDC. For current PS and EF data sets this panel also allows the user to specify a compression ratio used for the estimate.
  • Added the following zEDC graphs: Projected zEDC CPU Savings , Projected zEDC I/O Count , and zEDC Dataset Analysis .
  • Reporting on selection detail of the SMF 14/15s used in the zEDC analysis has been added.

V1.4.6 (08/29/2014)
  • Added the IIP CP Time column on the zBNA main panel.

  • The Find and Find Next are now available on the Edit menu on several of the zBNA panels that contain tables.
  • 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)
