CRITERIA & FORMAT
• Focus is on a “vanilla” migration and what performance
changes might arise as a consequence
– With one exception: Migrating from ESA mode/31-bit processing
to zArchitecture mode/64-bit processing
• Releases covered -- OS/390 V2.10 through z/OS V1.6
• Release is identified for various performance comparisons
or benchmarks
• This is not a tuning presentation
• Reference material is identified
– Hyperlinks are active on PowerPoint Slide Show, which can be
downloaded. You may need to use CTRL-ESC to view reference.

SOFTCAP
• Allows you to evaluate CPU, real storage impact of a
migration from OS/390 V1.1 through z/OS V1.6
• Options
–
–
–
–
ESA/390 vs. z/Architecture, or 31-bit vs. 64-bit
WLM Compatibility vs. Goal Mode
Demand Paging to/from Expanded Storage
RSM Services Intensity
• CICS, IMS release migration estimation is also provided
– CICS/ESA V3.1.1 through CICS TS V2.3 + MRO (FOR, AOR, TOR)
– IMS V3 through V8 + Fast Path & Full Function
• You can specify workload % for CICS, IMS, DB2, TSO,
batch, and system where total = 100%
• Requires Java Runtime 1.4.1, part of download package

CONCLUSIONS
• The mean CPU utilization increase between OS/390 V2.10 &
z/OS V1.4 is 1.26%, 1.38% for V1.4.2, 1.56% for V1.5
– For 31-bit to 31-bit or 64-bit to 64-bit
– z/OS V1.6 only requires .5% more
• The mean CPU increase between OS/390 V2.10 & z/OS V1.4 is
4.4%, 4.5% for V1.4.2, 4.76% for V1.5, 3.6% for V1.6
– For ESA mode/31-bit to zArchitecture/64-bit migration
• The CPU increase between z/OS V1.2 & V1.4 through V1.5 is
between .4% and .7%, V1.6 is actually a decrease of .34%
– The increase between V1.4 & V1.5 is .34%, V1.6 is a .8% decrease
• Batch processing appears to benefit the most from z/OS V1.6
• In zArchitecture/64-bit mode, OS/390 requires the least storage
(35M), z/OS V1.2, V1.4, & V1.4.2 the most (42M), and V1.5/
V1.6 requires marginally more than OS/390 V2.10 (37M)
• z/OS V1.6 is the best performing z/OS release

• Uses RMF or SMF input
• Analyzes and estimates processor utilization, workloads,
storage usage, and I/O performance
• Evaluates parallel sysplex
• Simulates zSeries performance
– ITR ratios and partitioning costs are derived from zPCR
– LSPR data is also factored in
• Simulates non-zSeries performance
– PCRW data is used instead of zPCR data
– LPAR/CE is used to estimate partitioning overhead

zPCR
• zPCR is comprised of LSPR ITR ratios and detailed LPAR
configuration detail that predict performance/capacity
• Capacity figures are derived from user-defined values
– User-selected processors
– Scaling-factor and scaling metric
• Processor Capacity Tables include standard CPs, ILF CPs
– z/OS, z/VM, and Linux workload-based LPAR configurations are
supported
– LSPR workload primitives, predefined workloads, user-defined
workloads can be used
• Primitives and predefined workloads are different mixes of work, such
as transaction intensive, batch intensive, blends of the 2, Websphere,
Linux, and I/O intensive
• LPAR configurations include traditional, IFL, and ICF CPs
– Capacity assessment is performed for each LPAR and overall host

Non-zSeries Tools
• PCRW provides similar function to z/PCR for processors
and LPAR configurations on pre-zSeries processors
–

–
–
OS/390, VM/ESA, and VSE/ESA environments are supported
Evaluates processor consolidation as well
Sizes applications
Analyzes workload growth
Analyzes workload characteristics
• LPAR/CE evaluates LPAR performance/capacity for prezSeries processors
– Provides detailed LPAR capacity analysis and planning information
• These tools can be used in conjunction with zPCR
– They can provide capacity data, etc., for processors not supported
by zPCR (for example, upgrade from non-zSeries to zSeries)
– Workloads must be similar and base ITR, scaling, etc. must be
similar
