Need Help Determining What WLC Means for You?

I/S Management Strategies can work with you to help you understand zSeries, z900, z/OS and Workload License Charges. Every customer with more than 300 MIPS of installed capacity must analyze WLC.

IRD changes some of the PR/SM configuration guidelines used in the past. Configuration of PR/SM on z900s will be different than on 9672s. Today many data centers are configured in an effort to control software costs. With Workload License Charges, IRD and Parallel Sysplex many of these configurations can be changed to further reduce your expenses and improve the flexibility within your configuration.

IBM Delivers Sub Capacity Pricing

On July 23, 2001 IBM announced sub capacity pricing without the IBM License Manager. Instead IBM developed the Sub Capacity Reporting Tool. You can use this tool to report to IBM your LPAR sizes and the products running in the LPARS. Defined Capacity, managed by WLM with the 4-hour rolling average is available to limit the size (CPU consumption) of each LPAR. Read the WSC flash, and Don't use Defined Capacity by mistake.

Effective on October 1, 2001 you can be using Workload License Charges. The high level requirements are:

• a z900 server,
• z/OS LPARs,
• no OS/390 LPARs (z/VM and Linux LPARs are allowed)

Take our WLC Survey

I'm curious as to how many installations are using Workload License Charges (WLC) at less than full machine capacity. You can help by filling out the survey below whether you are using z900 and z/OS or not.

The survey is now closed. Click this link and the survey will be emailed to you. After you fill out the survey you can "reply" and return it by email or fax it to +1 (414)332-8771.

Join the IBMLM-L List

This list was created for IBM's License Manager rather than include LM discussions on IBMMAIN-L. Update: the IBMLM-L list is no longer active, please consider LPAR-PRICING-L!

MXG Calculates Your 4 Hour Rolling Average

Gartner: Moving to new IBM mainframes should reduce users' software costs Computerworld (27Nov2000)

IBM's new pricing option for mainframe users could save companies thousands of dollars per month. But to qualify for the full cost benefits, customers must first move to IBM's new zSeries 900 mainframe hardware, run the z/OS operating system in full 64-bit production mode and use the company's new IBM License Manager (ILM) technology.
