At a Glance

PC-based capacity planning and performance modeling for OS/390® or z/OS-based mainframe computers:

  • Optimize mainframe system resource
  • Deliver optimum service for customer/user satisfaction
  • Enter a proactive mode of planning or predicting:
    • Additional or new workloads
    • Future upgrades and other long-term system capacity requirements
  • Gather/report on day-to-day workload data
  • Model "what-if" versus actual scenarios

Overview

IBM Tivoli® Performance Modeler for z/OS™ is a PC-based performance modeling and capacity planning tool that runs on Windows® — a new option for system management on the zSeries and System/390®.

In the S/390® environment, the primary benefits of PC-based performance modeling:

  • Allow you to review the impact of workload changes on your current S/390 environment as well as future processor types
  • Free mainframe time and expense in performing capacity planning tasks
  • Examine what-if scenarios without the expense of running actual scenarios
  • Predict the impact of hardware and software changes
  • Use sophisticated simulation techniques for a high degree of accuracy
  • Indicate current processor utilization against processor capacity
  • Predict when increased processor capacity will be required
  • Allow graphing of workload performance
  • Provide integration with familiar spreadsheet tools such as Lotus® 1-2-3® and Excel

Performance modeling is now as portable as your PC or laptop.

With growing operating system complexity and the huge impact of responding to workloads, basic CPU utilization is no longer enough. Performance Modeler can model:

  • Number and speed of CPUs
  • Disk I/O response times
  • Paging rates (auxiliary and Expanded Memory paging)
  • Logical partitioning (LPAR) definitions and parameter changes

Advantages

Performance Modeler enables you to plan for acceptable levels of computing while managing your IT costs. You define your acceptable limits on response times, level of workloads, and service available to the end user using:

  • Tracking and reporting function: Capture and report resource usage, including historical charts for trend analysis.
  • Workload characterization and priority: You decide the level of aggregation for data reporting.
  • End-to-end performance modeling that spans zSeries and S/390.
  • Modeling input data manually entered or captured from other tools (RMF™, CMF).
  • Fast, efficient simulation techniques.
  • An easy-to-use interface with a clear link between the data you input and the resulting reports.

Bottom line: With good data, you make better decisions.

Key Prerequisites

  • Any PC that runs Windows/98, or later (recommend 300 MHz or greater)
  • IBM z/OS Resource Measurement Facility (RMF), or equivalent software (such as CMF MONITOR from BMC Software)
  • Excel or Lotus 1-2-3 spreadsheet

Description

By definition, a system is out of capacity when it can no longer meet the service commitments made to the end users. To properly predict when capacity needs increase, any capacity planning tool must be able to predict — or model — the impact of change on end-user performance. Multitier platforms and reliance on Internet, intranets, and extranets makes prediction very difficult. Capacity planning and performance modeling tools must consider all the components in the delivery of service. Systems programmers or operations professionals can use capacity planning — or performance modeling — tools to simulate the actual performance behavior of the mainframe computer. They can predict the output of these complex mainframe systems and also the impact of changing hardware or software. With this data, you can manage your zSeries or S/390 proactively.

After building and calibrating a baseline model, all results will be compared to that baseline. Changing configuration definitions is relatively simple.

Simulation Versus Analytic Models: Tivoli Performance Modeler creates a simulation model that can easily be modified to reflect changes in the operating system when they occur.

Modeling techniques generally fall into one of two categories — Simulation or Analytic. In some cases, hybrid models have been developed which use combinations of both techniques. The differences between these techniques are as follows. Analytic models consist of mathematical equations that describe the processes being modeled. Analytic models are used when the processes being modeled are well understood and can be described as mathematical expressions. Simulation models rely on running the actual process being modeled, but in a simplified form. Since these processes take place over time, simulation requires running (simulating) these processes over and over in order to reach a steady state that mimics the real process.

Analytic models are, by their nature, fast to run and require less processing power than simulation. Analytic models execute a number of mathematical equations and can run in seconds or less. Computer-based simulators must execute lots of instructions in order to simulate one point in time. Since simulators must model a period of time, many iterations must take place before the results are meaningful. This means simulators can run for an extended amount of real time, and use a larger amount of computer resources compared to analytic models. Simulators are used today to predict complex processes where analytic equations are not suitable. Some examples of these simulators are models that are used to predict weather and the presence of oil deposits. These models require large amounts of computer resources, but produce results that are not attainable with analytic techniques.

In the early days of mainframe computers, operating systems were simpler than they are today. Over time, features have been added and operating system complexity has grown. Older analytic models, which were developed to predict computer performance, have found it difficult to keep up with the changing nature and complexity of today's systems. Simulation models have a distinct advantage over analytic models when it comes to staying current. Simulators can be easily reprogrammed to model changes in the operating system as they occur.

Model Input and Output: Performance Modeler can model nearly every hardware and software change you could make.

It is a powerful tool in helping you analyze "what-if" scenarios. For example, it can model the effects of:

  • Changing hardware configuration
  • Changing logical partition (LPAR) mode parameters, including the number of logical CPUs per LPAR and any weighting factors
  • Changing the growth rate of workloads

The input definitions are specified on three easy-to-understand screens:

  • Configuration screen
  • Workload activity screen
  • LPAR definition screen

As you build and calibrate your capacity planning model, you can capture numeric or text data. If you accumulate weekly reports, several weekly reports can be merged to produce a monthly report, and so on.

An output metric is the performance of each workload modeled:

  • For online workloads — the average response time (in seconds)
  • For batch workloads — the average elapsed time

Graphing Workload Performance: While the simulator is running, you can see a graphical picture of workload performance. You can choose up to four workloads from a panel of 20 workloads to display in a continuously updated line graph.
