Actually, for IBM IPLA ("One-Time Charge") software, you have two choices.
Yes, you can purchase full licenses to match the newly increased capacity.
(In fact, you can purchase as much extra IPLA capacity as you want, as long
as it meets or exceeds your actual four hour rolling average usage at all
moments in time.) However, for the vast majority of IPLA software products
IBM also offers per-day-per-MSU prices. So, just like the Capacity On
Demand CP(s) (daily "MIPS"), you can buy single day(s) of IPLA software.
That's the default plan, actually.To pick an example at random, if you turn on Capacity On Demand for one day (i.e. less than 24 hours), and you raise your softcap by 1 MSU, and you run one additional MSU of WebSphere Application Server for z/OS Version 7 (5655-N02) above your existing entitlement, then you would be charged $5 (U.S. price) for the additional MSU-day. (Yes, you read that correctly. One MSU for one Capacity On Demand day of WebSphere Application Server for z/OS is 5 dollars in the U.S.), Or, if you prefer another way to look at it, let's suppose that single additional MSU lets you run one additional transaction per second. If you do that for 20 hours, that's 72,000 more transactions (20 x 60 x 60). Thus the price for the extra WebSphere use is $0.0000694 per transaction. That's about 7/1000ths of a penny. Note that IPLA MSU-day prices are flat. There is no price curve here for either quantity of MSUs or duration. In other words, if you are a customer with a System z10 BC Model A01 (3 MSUs), and you activate Capacity On-Demand to add one additional MSU, you would pay $5 additional for WebSphere Application Server per day. This is the same price as a big customer would pay increasing their 1000 MSU machine (and WebSphere use) to 1001 MSUs. The smaller customer increases MIPS by 33% for one day, while the latter customer increases MIPS by 0.1%. It's only $5 per WebSphere MSU-day in both cases. MLC software is still calculated based on monthly peak (that's what the "M" means), so if you increase your peak four hour rolling average MSUs in any particular month then you're charged according to your new peak, per sub-capacity product. For example, if you increase your IMS and z/OS use by one MSU but not your CICS, then you'd pay for the additional MSU only for IMS and z/OS for that particular month. (I'm assuming EWLC or VWLC here.) Anyway, I just wanted to expand a bit on what Jacky Hofbauer said. Hope that helps. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Based in Tokyo, Serving IBM Japan / Asia-Pacific E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
