Sorry to reply so late to a post, but what do you do about third party vendors? They usually want their money for the CPU power you have and they don't care if you cap it to 1% of the cpu. At least that's what I have seen.

Perhaps, but consider that this strategy can pay off big time when you size your box for spikes instead of average load. You can give management a knob to adjust how much they pay for software, and they can change their mind every month. A pleasant scenario: buy a box big enough to do your year end processing in days instead of weeks. Open the cap and let the box run full out for a month, then throttle back to, say, 50%. You pay full fare for software that month, but much less for the other 11 months. True, there are software vendors that won't play ball. But market pressures are intense and the hard nosed vendors are either giving in or giving out. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Marian Gasparovic Sent: Thursday, May 07, 2009 7:16 AM To: [email protected] Subject: Re: Another Group Capacity question John, yes, you can get more MSUs then is your defined capacity and SCRT will still report only your defined capacity. This is nicely described in SCRT User's Guide. So as others pointed out - you are never capped below defined capacity to compensate for those MSU over limit. Unbelievable, but true :) Marian Gasparovic IBM Slovakia On Wed, May 6, 2009 at 3:00 PM, McKown, John <[email protected]> wrote: >> -----Original Message----- >> From: IBM Mainframe Discussion List >> [mailto:[email protected]] On Behalf Of Hal Merritt >> Sent: Tuesday, May 05, 2009 5:16 PM >> To: [email protected] >> Subject: Re: Another Group Capacity question >> >> No on two counts.

So I can actually, for a while, get some "free" MSUs. In my case, during month end, we literally run at 100% CPU for about 10 hours. So from what you're telling me, I can run for somewhat less than 4 hours at (maybe) 66 MSUs (well, depending) but once I've hit the 59 MSUs in a single 4 hour period, I will continue at 59 MSUs until my CPU requirements drop down below 59 MSUs. But I won't get any "trough" effect to make the average "come out right". That is good to know. > >> >> It would stay at 59 until the R4A once again dropped below >> that.

But thanks for clarifying that the 4HRA is not just calculated at an hourly boundry, but "continuously" as the system runs. > > -- > John McKown > Systems Engineer IV > IT > > Administrative Services Group > > HealthMarkets(r) > > 9151 Boulevard 26 * N.
