 ENUS202-236.PDF (39KB)


At a Glance

WebSphere Studio Workload Simulator:

  • Simulates multiple Internet browser users ("virtual" users), for load-testing Web servers, such as WebSphere Application Server.
  • Offers a graphical, Windows-based user interface through which you create and edit test scripts, control the execution of the test, and analyze test results.
  • Features a controller "capture" function that helps you generate test scripts automatically and quickly.

For ordering, contact:

Your IBM representative, an IBM Business Partner, or IBM Americas Call Centers at 800-IBM-CALL (Reference: LE001).

Overview

WebSphere® Studio Workload Simulator conducts stress, performance, regression, and capacity planning tests. It can simulate multiple Internet browsers to test Web servers. This eliminates the need for using large numbers of "real" ("live") users to generate Web traffic.

Almost anything that a user can do at a browser, WebSphere Studio Workload Simulator can do faster, more reliably, and typically for less cost.

WebSphere Studio Workload Simulator consists of two components:

  • A graphical, Windows®-based "controller" through which you create and edit test scripts, control the execution of the test, and analyze test results.

    With its simple "capture" function and your browser, WebSphere Studio Workload Simulator provides an automated way to create test scripts. The captured scripts are visually editable.

  • The "engine" executes the test script. The engine resides on a S/390® server.

You can use the "virtual users" created by WebSphere Studio Workload Simulator to validate any Web-serving environment.

Key Prerequisites

One of the following:

  • OS/390® V2R10, or later (5647-A01)
  • z/OS™ V1, or later (5694-A01)

A Windows 2000 or Windows XP workstation, with a Microsoft™ Internet Explorer browser V5.x, or later

Planned Availability Date

October 25, 2002

Description

In e-business, transaction volumes can fluctuate rapidly. A sudden, unplanned increase in transaction volumes can tax the traffic-handling capabilities of the Web-serving environment. The profitability of the enterprise can be seriously impacted. WebSphere Studio Workload Simulator is used for load-testing and for validating an infrastructure that is capable of handling production-level workloads.

WebSphere Studio Workload Simulator enables actual programs to operate as they would under actual conditions. The evaluation can start with a low volume of traffic and proceed in an orderly manner to a high-volume level. Because programs and associated hardware are integral parts of the simulation process, WebSphere Studio Workload Simulator provides an approximation of the true operational environment.

WebSphere Studio Workload Simulator helps reduce testing time and testing resources while improving the thoroughness of testing. It provides repeatability for functional testing and regression testing, large volumes of Web traffic for stress testing, and reporting capabilities for system performance testing.

WebSphere Studio Workload Simulator has a graphical, Windows-based user interface through which you can create and edit test scripts, control the execution of the test, and analyze test results. The controller also features a "capture" function, which helps you generate test scripts automatically and quickly.

Section 508 of the U.S. Rehabilitation Act

WebSphere Studio Workload Simulator is capable as of October 25, 2002, when used in accordance with IBM's associated documentation, of satisfying the applicable requirements of Section 508 of the Rehabilitation Act, provided that any assistive technology used with the product properly interoperates with it.

Value Unit Based Pricing

Value Unit based pricing will help to align the prices of these products to the principle of the PSLC pricing curve, which provides for a lower price per MSU (millions of service units per hour) for larger capacities.

There is also a price benefit when customers grow their capacity. Additional capacity will be based on the number of Value Units (MSUs) the customer has already installed, for example, additional capacity will not be priced starting at the base with a higher price per unit but on the capacity that is already installed.

Note that Value Units of a given product cannot be exchanged/interchanged/aggregated with Value Units of another product.

International Program License Agreement (IPLA) and Subscription and Support Considerations

IPLA licenses can be transferred from one machine to another within, but not limited to, an enterprise. The customer may aggregate the capacity for all the processors the product is operated on to achieve a more economic price. This will result in a single Proof of Entitlement. It is the customer's responsibility to manage the distribution of Value Units within the limits of the entitlement of the product license.

Subscription and Support must cover the same capacity as the product license entitlement. Subscription and Support will be available in the country in which the agreement is made.

Product Positioning

WebSphere Studio Workload Simulator is a component of the Application Development Tools portfolio for WebSphere for z/OS. The other components are WebSphere Studio Asset Analyzer for z/OS and WebSphere Studio Enterprise Developer. These tools offer customers a solution that spans the application lifecycle, and provide application developers with powerful tools to help improve productivity and effectiveness during development, testing, and deployment of new and existing applications on the z/OS platform.

The products in this announcement have one charge unit — Value Units.

Value Units for IBM 9672 Processors will be based upon the full capacity of these systems. This is applicable to all S/390®-based systems that are measured on MSU capacity. Information on MSU capacities can be found in the IBM System/370™, System/390® and zSeries™ Machine Exhibit (Z125-3901).

Value Units for IBM eServer zSeries will be based upon full MSU capacity as defined in the Machine Exhibits.

There will be a tool available that provides support for transforming the MSU-based capacities of S/390 systems to new Value Units by calculating the applicable number of Value Units for a given number of MSUs.

Translation from MSUs to Value Units Example

           MSUs       Value Units/MSU
 
Base        1-3            1.00
Tier A      4-45            .45
Tier B     46-175           .36
Tier C    176-315           .27
Tier D    316+              .20

Note: For the actual translation from MSUs to Value Units for this product, refer below.

Ordering Example

The total number of Value Units is calculated according to the following example.

If the customer has installed 1,200 MSUs, the applicable Value Units would be:

Translation from MSUs to Value Units

            MSUs    *  Value Units/MSU  = Value Units
 
Base          3     *      1.00         =      3.00
Tier A       42     *       .45         =     18.90
Tier B      130     *       .36         =     46.80
Tier C      140     *       .27         =     37.80
Tier D      885     *       .20         =    177.00
 
Total     1,200                              284

When calculating the total number of Value Units, the sum is to be rounded up to the next integer.

  1 Value Unit
250 Value Units

Example: For a product running on machines with 1,200 MSUs requiring 284 Value Units, order the feature number for "1 Value Unit," quantity 34 and the feature number for "250 Value Units," quantity 1.

Terms and Conditions

Sub-Capacity Charges Terms and Conditions

IBM eServer zSeries software charges at less than full machine capacity for eligible Data Management (DM) and Application Development (AD) Tools apply when z/OS is running in z/Architecture™ (64-bit) mode on a zSeries 900, no other MVS™-based operating system is licensed to that server and the required information is provided by the customer in accordance with the applicable terms.

Sub-capacity charges for an eligible AD or DM Tool is based on the z/OS product-defined capacity. To obtain charges at less than full machine capacity for eligible AD and DM tools, the customer is required to:

  • Determine the MSUs needed for each machine on which the tools will run. Only machines on which the customer has implemented sub-capacity Workstation License Charges (WLC) according to the above terms and conditions, are eligible for charges at less than full machine capacity for the tools.
  • Use the product-defined capacity for z/OS (as specified on the Sub-Capacity Reports submitted to IBM for sub-capacity WLC) as the sub-capacity (MSUs) for each tool.
  • Submit any additional MSUs and/or Value Units required for each product along with the current entitlement in Value Units for each product.

Sub-Capacity Charges for AD and DM Tools

To be eligible for sub-capacity charges for AD and DM Tools, the machine on which the AD and DM Tools are running must be eligible for WLC sub-capacity charges, terms, and conditions. The customer must have signed the Attachment for zSeries Workload License Charges-Pre-ILM, Z125-6516, and submitted at least one Sub-Capacity Report to IBM as defined in the attachment.

With sub-capacity charges, the charge for an eligible AD or DM Tool is based on the z/OS product-defined capacity. To obtain charges at less than full machine capacity for each eligible AD and DM Tool for each machine, the customer should:

  • Determine the MSUs needed for the machine on which the tools will run. In a data sharing environment, determine the aggregate MSUs needed on the machine where the tools run. Use the product-defined capacity (MSUs) for z/OS (as specified on the Sub-Capacity Reports submitted to IBM for sub-capacity WLC) as the sub-capacity (MSUs) for each Tool.
  • Submit any additional MSUs or Value Units required for each product along with the current entitlement in Value Units for each product.
  • If the use of sub-capacity pricing terms for AD and DM Tools results in a reduced requirement for Value Units, thus freeing up entitlements, customers can reallocate the entitlement difference by distributing the Value Units across a larger or different set of systems, or reserve them for future growth. There will be no refunds for these freed up Value Units. Subscription and Support volumes and entitlements for existing contracts will continue to be at the same levels as the acquired licenses.

Management of the Value Unit entitlements continues to be a customer responsibility. If one of the following occur on a machine to which AD or DM Tools are licensed, the customer must determine if additional Value Units and Subscription and Support need to be ordered for those tools to cover the increase:

  • The z/OS product-defined capacity is increased.
  • The requirements for WLC sub-capacity charges are no longer met.

Licensing: IBM International Program License Agreement (IPLA). Proofs of Entitlement are required for all authorized use.

The following agreement applies for maintenance and does not require customer signature:

  • IBM Agreement for Acquisition of Support (Z125-6011)
