• Does Your Installation Have 1/2 Second Response Time? - View a .PDF file (76Kb) containing a paper that describes variability in the response time of modern DASD subsystems that is not typically observed by using disconnect time in a new manner. A proposal is being made to combine existing data sources (SMF42 and RMF74) to produce more meaningful data for performance analysis.

• Workload License Charges Optimization - This new presentation, from the November 2003 z/OS Expo discusses how to optimize your WLC environment. This session is useful to those sites alreadying using WLC or EWLC and sites that are considering WLC. Topics covered include: Combining LPARs, Splitting LPARs, Consolidation of LPARs, Controlling the 4-Hour Average, Using Defined Capacity and more!
  
  
• LPAR Initial Processing Weights, Defined Capacity and the Softcap - This presentation discusses how the LPAR parameters work with softcapping. The "Phantom Weight" is discussed along with "pulsing of the soft cap". Also be sure to see our page on WLC Reference materials.
  
  
• Real Life Analysis of WLC - View a .PDF file with the presentation from the February 2003 Share Conference. This is a total replacement for earlier versions and completely rewritten with new examples. One organization's IBM software products are used throughout an example of moving from PSLC to WLC. Each of the steps in the analysis is explained including creating the software inventory, mapping the software to the LPARs, and reviewing likely growth scenarios. Each scenario is then "priced" via WLC. Other current issues of measured usage, product features and questions about whitespace are also discussed.
  
  
• IRD: What LPAR Clusters Can Do For You! - View a .PDF file with our presentation from Share Session 2525. This presentation expands on what was presented at CMG2000 to include details on how the soft capping of Workload License Charges is implemented. Specific IRD recommendations are also presented.
  
  
• IBM's Workload License Charges and the Effects on Capacity Planning - View a .PDF file with the presentation from the San Francisco Share Conference. This presentation discusses Workload License Charges stressing how Capacity Planning will be impacted by WLC. Examples are shown that explain 'Defined Capacity', the 'rolling 4 hour average', and how WLM uses PR/SM to implement soft capping. The steps to follow when planning your environment are included along with many recommendations. Also be sure to see our page on WLC Reference materials.
  
• Workload License Charges: A Consultant's View - View a .PDF file with the presentation from the October z/OS Expo Conference. This presentation discusses Workload License Charges, IRD, the 'rolling 4 hour average', soft capping and other topics. Also be sure to see our page on WLC Reference materials.
  
  
• Reporting on Workload License Charges - View a .PDF file with the presentation from the October z/OS Expo Conference. This presentation discusses how to write reports to analyze and plan for Workload License Charges, IRD, and 'rolling 4 hour average'. Also be sure to see our page on WLC Reference materials.
  
  
• IRD: What LPAR Clusters Can Do For You! - View a .PDF file with our presentation from Share Session 2525. This presentation expands on what was presented at CMG, z/OS Expo and other Share conference to include details on how the soft capping of Workload License Charges is implemented. Specific IRD recommendations are also presented.
  
  LPAR and Parallel Sysplex Capacity Planning Update: This paper focuses on explaining LPARs and sysplexes to senior management. A variety of illustration, visualization and graphical techniques are presented to explain the CPU allocation of the LPARs in a single system. A visualization of LPAR engine allocation is used to describe the operation of logical partitioners. That is, how dynamic dispatching can be represented, the limits of capacity for a partition and “push points” between partitions. The concept is then expanded to include the LPARs within a Parallel Sysplex. The third area discussed is one physical machine having LPARs in multiple parallel sysplexes. Who is in control: the LPAR dispatcher, or the separate Workload Managers of the Parallel Sysplexes?

• IRD, LPAR Clusters and Changes in PR/SM - View a .PDF (100Kb) file with the presentation from CMG 2000's Tuesday BOF session. About 60 people gathered to hear our understanding of the changes in PR/SM. The discussion included:
  • What are LPAR clusters?
  • IRD changing the weights of partitions
  • IRD adjusting the number of LPs in an LPAR
  • How Channel Subsystem Priority Queueing works
  • An Introduction to Dynamic Channel-Path Management.
  The discussion lasted nearly 90 minutes, with people staying to talk about IRD when they could have been at the CMG evening party with free food.
  
  
• IBM's New Workload License Charges - View a .PDF (65Kb) file with the presentation from CMG 2000's Wednesday BOF session. Another 60 people showed up to hear and participate in discussion about the future of software pricing on the mainframe platform. We discussed certificates, how ILM works, it's modes of operations, how some exceptions are handled, what the other vendors are doing about ILM, etc. Again, a lively discussion. See our page on WLC Reference materials.
  
  
• Upper Bound Analysis for e-Business Capacity Planning: Often the analysis of historical data is forecasted with various regression techniques. Regression tries to provide a mathematical description of the relationship between variables. Occasionally the data does not forecast well; the forecast does not match the actual data, especially with e-business. When this does occur various techniques are tried to "make the data work". A new technique using z-scaling is proposed that uses all of the data points without filtering or summarizing. This technique helps analysts assess the risks of their forecasts by providing a useful upper limit.
  
  
• Crossing the Batch Rubicon: Understanding the Performance Implications of Job Dependencies - View a .PDF (25Kb) file containing a paper that presents a methodology for analysis of batch schedules and critical paths. SAS/OR is used to combine SMF and RMF data with your scheduling system.
  
  
• Boosting Performance with Capacity Planning - This paper (29Kb PDF) shows how Capacity Planning can help you postpone a hardware purchase or upgrade.
  
  
• Understanding the Performance Characteristics of EMIF Channel Subsystems - (46Kb .PDF). A paired test methodology is employed to compare the performance characteristics of DASD subsystems supported by dedicated ESCON channels with shared EMIF channels on a partitioned system. The results of the paired tests provide comparisons of device service times, channel utilizations, PEND times, and other critical I/O subsystem metrics.
