Overview
Bottom rule

IBM provides Integrated Workload Pricing (IWP) to enhance utilization reporting capabilities of systems running IBM z/OS®, which can improve the price/performance for eligible Monthly License Charge (MLC) programs running within the same logical partition (LPAR) as select defining programs. These programs are listed in the Description section, Integrated Workload Pricing Defining Programs. The IWP enhancements to the reporting capabilities in z/OS enable the IBM Sub-capacity Reporting Tool (SCRT) to calculate the general purpose processor time consumed by eligible defining programs and adjust the reported MSU values for eligible MLC programs running in the same LPAR.

The WebSphere® family of programs for z/OS can help you modernize and extend existing business applications to drive business agility. Significant performance and operational benefits can be achieved when WebSphere middleware is collocated with System z® MLC programs within the same LPAR instead of separate LPARs. However, collocating these programs can have the effect of increasing MLC software charges due to the incremental processing in the LPAR attributable to the running of WebSphere programs. IWP has the potential to adjust and significantly improve the software price performance for certain z/OS programs when they are running in a collocated LPAR with WebSphere IWP Defining Programs, compared to running the programs in a collocated LPAR without IWP.

IWP enhances IBM sub-capacity Advanced Workload License Charges (AWLC) described in the IBM sub-capacity pricing announcement for z/OS. For additional information, refer to Software Announcement 210-238, dated July 22, 2010.

For a list of the programs eligible to define the IWP adjustment and those eligible for adjustment, refer to z/OS programs eligible for IWP option for AWLC sub-capacity clients in the Description section.

Key prerequisites
Bottom rule

IWP is available only when running specific eligible programs installed on zEnterprise 196 machines that have implemented sub-capacity pricing under AWLC terms and conditions, as specified in the Integrated Workload Pricing addendum to the AWLC.

Prerequisite hardware and software requirements are:

  • z196 Enterprise System processor
  • z/OS V1.10, or higher, with SMF APAR OA31615
  • Installation and use of SCRT V19.2.0
  • Use of the SCRT IWP control statement

For z/OS guest systems running under z/VM®, all z/OS guest systems must be at z/OS V1.10, or higher. One of the following is required:

  • z/VM V5.4 with APAR VM64798
  • z/VM V6.1 with APAR VM64879

IWP billing effective date
Bottom rule

Sub-capacity licenses with AWLC charges including the IWP adjustment cannot be billed until users submit a Sub-capacity Report containing programs with MSUs adjusted by IWP. SCRT V19.2.0 is required in order to submit Sub-capacity Reports containing programs adjusted by IWP. SCRT V19.2.0 availability is February 10, 2011.

To enable IWP, z/OS SMF APAR OA31615 must be applied prior to the collection of system utilization data. The earliest date for collecting system utilization data eligible for IWP adjustment is February 2, 2011.

You may generate the first Sub-capacity Report containing MSUs adjusted by IWP on March 2, 2011. This report, for data collected during the February reporting period, may be submitted between March 2 and March 9, 2011, and will have a billing effective date of April 1, 2011. Therefore, the earliest billing effective date for programs with MSUs adjusted by IWP is April 1, 2011.

Description
Bottom rule

IWP enhances z/OS system utilization reporting capabilities, which can significantly increase price/performance for eligible MLC programs when running in the same LPAR as select IWP Defining Programs.

Determining eligibility for Integrated Workload Pricing

IWP requires implementation of AWLC under sub-capacity terms.

z/OS programs eligible for IWP option for AWLC sub-capacity clients

Integrated Workload Pricing Defining Programs

Program ID  Program name
 
 5655-N01   IBM WebSphere Application Server for z/OS V6
             Service level 16, or higher
 5655-N02   IBM WebSphere Application Server for z/OS V7
 5655-N53   WebSphere Process Server for z/OS V6

At this time, Integrated Workload Pricing is available only in connection with select qualified IBM programs known as IWP Defining Programs. IBM may evaluate authorizing additional programs as eligible IWP Defining Programs over time if warranted, based on customer demand and subject to an appropriate level of qualification of those programs.

The corresponding sub-capacity System z IPLA programs with Reference-Based terms receive the same sub-capacity adjustment as their parent program.

Calculating the billable MSUs for applicable Monthly License Charge programs

SCRT calculates the 4-hour rolling average of the general purpose processor time consumed by the IWP Defining Programs and subtracts those values from the traditional sub-capacity values for the MLC programs eligible to be adjusted by IWP, on an hour by hour basis, per LPAR.

For the case where the z/OS system is a guest system running under z/VM, each z/OS guest system is treated as its own LPAR when applying any sub-capacity adjustments for IWP.

The program values for the same hour are summed across all of the LPARs and z/OS guest systems running under z/VM in which the program runs to create an adjusted sub-capacity value for the program, for the given machine, for each hour.
