IBM Workload Simulator for z/OS and OS/390 Provides a Structured and Systematic Approach to Testing

 ENUS202-176.PDF (38KB)


At a Glance

Workload Simulator performs the following testing functions:

  • Function Testing: Testing a new program or subsystem to determine that it performs according to specifications. Test cases are prepared to verify that the code will execute the job it is designed to run.
  • Regression Testing: Testing a modified program or subsystem to determine that the change has had no effect on the modified portion. In regression testing, all of the test cases that were run against the unmodified program must be run against the modified program, and each test case must produce the same results as before.
  • Performance Testing: Testing the system to determine that it can handle the projected throughput with acceptable response times.

For ordering, contact:

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

Overview

Workload Simulator is used to conduct stress, performance, regression, function, and capacity planning tests. It can simulate user-specified terminals and the associated messages, significantly decreasing the number of terminals and reducing terminal operator time. Anything that a user can do at a terminal, he can do faster, more reliably, and typically for less cost with the help of Workload Simulator.

Workload Simulator provides SNA, CPI-C (LU 6.2), and enhanced TCP/IP support.

Workload Simulator Test Manager (Test Manager) is a user interface provided with Workload Simulator. Test Manager is an integrated utility that guides the user through the test process. It helps with the development and management of test cases, the automation of test runs, and the analysis of test results.

Key Prerequisites

One of the following:

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

Planned Availability Date

August 16, 2002

Description

In the world of e-business, not only do transaction volumes fluctuate, the changes can be very abrupt. A sudden, unplanned spike in transaction volumes can tax the traffic-handling capabilities of the network. In the end, the profitability of the enterprise can be seriously impacted. IBM Workload Simulator can help test systems, applications, and networks and ensure that the enterprise infrastructure is capable of handling the additional workload.

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, Workload Simulator provides a close approximation of the true operational environment.
  • Can help reduce testing time and testing resources while improving the thoroughness of testing for teleprocessing systems. Workload Simulator provides repeatability for functional testing, a collection of comprehensive transaction messages for regression testing, large volumes of message traffic for stress testing, and message rate statistics for system performance testing.
  • Can also be used as an availability monitor. By simulating a terminal that transmits messages to an online system at predetermined intervals and analyzing the response times to these messages, Workload Simulator can monitor system availability and transaction response times to ensure service-level requirements are met.
  • Test Manager is a user interface provided with Workload Simulator. Test Manager is an integrated utility that guides the user through the test process. Test Manager helps the user with the development and management of test cases, the automation of test runs, and the analysis of test results. For greater flexibility, Test Manager offers three modes of operation that control the amount of interaction the user may observe with Workload Simulator.

Value Unit Based Pricing

Value Unit based pricing will help to align the prices of these products with the principle of the Parallel Sysplex® License Charge (PSLC) pricing curve which provides for a lower price per millions of service units per hour (MSUs) for larger capacities.

There is also a price benefit when customers increase their capacity. Additional capacity is based on the number of value units (MSUs) the customer has already installed, that is, 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.

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 economical price. This will result in a single Proof of Entitlement (PoE). It is the customer's responsibility to manage the distribution of value units (VUs) 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

Workload Simulator is the fifth component of the Total Cost of Operation Application Development Tools (TCO-AD Tools). The other four components are:

  • IBM File Manager for z/OS and OS/390
  • IBM Fault Analyzer for z/OS and OS/390
  • Debug Tool
  • IBM Application Monitor for z/OS and OS/390

The TCO-AD Tools 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.

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

Ordering Example:

The total number of value units is calculated according to the following example:

If the customer has installed 1000 MSUs the applicable value units would be:

Translation from MSUs to value units

                                   Value
                                   Units/                 Value
             MSUs         *        MSU           =        Units
 
Base             3        *        5.25          =         15.75
Tier A          42        *         .83          =         34.86
Tier B         130        *         .35          =         45.50
Tier C         140        *         .26          =         36.40
Tier D         685        *         .20          =        137.00
 
Total        1,000                                        270

When calculating the total number of value units the sum is to be rounded up to the next integer.

The value units should be ordered using the exact quantity of features representing the calculated number of value units. For example, in the above example, to order 270 Value Units, order quantity 1 of the "250 value units" feature and 20 of the "1 Value Units" feature. (Calculation: [1 x 250] + [20 x 1] = 270)

Basic License: To order, specify the program number, feature number 9001 for asset registration, the feature number of the desired distribution medium, and the correct number of Value Unit features as illustrated above. To suppress shipment of media, select the License-only option in CFSW.

Terms and Conditions

Sub-Capacity Charges Terms and Conditions

zSeries software charges at less than full machine capacity for eligible Data Management and Application Development Tools apply when z/OS is running in z/Architecture (64 bit) mode on an IBM eServer 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 Workload 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 Application Development (AD) and Data Management (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 total number of 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 and/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 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 occurs 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 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 (PoEs) are required for all authorized use.

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

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

These products are licensed under the (IPLA), the associated Agreement for Acquisition of Support, and the Addendum for Support (Z125-6312), which provides for support with ongoing access to releases and versions of the program.
