Batch Model has been enhanced to model Power9 processors.

After applying the required PTF, use the commands below to restart your IBM Navigator for i server.

OSP-OTHER Batch Model support for 5.4 and 6.1 collection

PTF/FIX #: SI55981 - IBM i
LICENSED PROGRAM: 5770SS1

DESCRIPTION OF PROBLEM FIXED FOR APAR SE61159 :
-----------------------------------------------
   The following problems are fixed in this APAR:
   1)Support for 16 wait buckets for collection data of V5R4
   2)Substitute JBCPU for JBINDCPU for V6R1 and V5R4 data
   3)Support concurrently creating model from multi-collections

CORRECTION FOR APAR SE61159 :
-----------------------------
   1)V5R4 collection only provides 16 wait buckets, however Batch
   Model retrieved data from 32 wait buckets. This has been fixed
   by adding logic to handle 16 wait buckets for V5R4.
   2)JBINDCPU is not available below V7R1, so Batch Model could not
   get CPU data in those cases. This has been fixed by using JBCPU
   as substitution for JBINDCPU for V6R1 and V5R4 collection.
   3)Batch Model was using a same temporary file to merge data from
   multi-collections. This has been fixed by merging data into
   different temporary files.

OSP-MSGCPFB50B-T/QPYBBCHMDL Batch Model merge fails

PTF/FIX #: SI55899 - IBM i
LICENSED PROGRAM: 5770SS1

DESCRIPTION OF PROBLEM FIXED FOR APAR SE61102 :
-----------------------------------------------
   The following problems are fixed in this APAR:
      1) Batch Model merge operation fails with MSGCPFB50B.
      2) Modeling processor changes while keeping the same number
      of processing units as the original configuration shows no
      changes to workloads in the modeled results

CORRECTION FOR APAR SE61102 :
-----------------------------
   1) The Batch Model merge failed because the modeled workloads
   were not properly merged. This has been fixed by correcting the
   algorithm which merges the workloads.

   2) The modeling algorithm was ignoring any processor changes
   when the number of processing units remained the same as in the
   original configuration. This has been fixed by detecting changes
   to any of the processor attributes, not just processing units.

Batch Model has been enhanced to model Power8 processors. You must apply both PTFs SI54715 and SI54462.

After applying the required PTFs, use the commands below to restart your IBM Navigator for i server.
