Hi there,

I would like to ask you how can I check:

How many MIPS are defined on partiton? (I just need the number)

Some commands or any other way.

Thank you for your time
Karel Stromsik

Hehe. I am part of the team who is working on data revalidation. I am doing it FOR Management. I appreciate your reply but is not what I need. Any sugestions? icon_wink.gif

IBM has been saying to replace MIPS with MSU for many years now -- and both numbers are not partition related, they're hardware related. Given a particular hardware configuration, the MSU rating is pretty much considered a constant (at least for a given workload -- but that opens up a big can of worms we'll leave alone for now).

Google MIPS MSU and you can find a number of charts giving the MIPS and MSU ratings for various hardware platforms from z800 up to z10. Find your hardware and voila there's your MSU (MIPS) rating.

Hello,

How will this number be used? How is data revalidation related to cpu speed/usage?

MIPS are not typically allocated by partition. Jobs running in partitions use cpu cycles (among other resources), but this is not considered MIPS for the job, let alone for the partition.

When we better understand your requirement, more usable replies may be posted.

Thank you again but I also know this. I call it catalogued value. I will put command d m=cpu and after that a I have exact type of CPU in order to find MIPS (MPU).

They gave me this description Number of MIPS defined on partition (Part power). So I dont know if it is the same as catalogued value.

I guess there is for example one CPU with for example 1000 MIPS. This Cpu is for 5 LPARS.

And now for first LPAR is dedicated 300 MIPS from the whole amount of 1000 MIPS

Second LPAR 200 MIPS etc.

The thing why I am interesting in these numbers is:

Company needs to make overview how many resources (MIPS, DASD, version of Z/OS) customer uses for their purposes. I am interesting only in MIPS because everything else I figured out.

If you need more info tell me. I really appreciate your time and replies

Hello,

A bit of progress with this last exchange icon_smile.gif We have been working with 2 different "partition" concepts. . .

The "partition" i referred was the initiator/partition where individual jobs are run. The "partition" from Karel's question is the entire lpar (if i understand correctly). When the system is configured, the amount of resources to be allocated to each lpar is defined. Your system support people should be able to show you these configuration entries for the lpar(s) you are interested in.

The info at this link may also provide some insight:

Yeah you understand well. We sometimes call LPAR - "partition" - missunderstanding. I will check link.

Ok can we do some math? icon_biggrin.gif

CPC SI = 2084.307

ID CPU
0 +
1 +
2 +
3 +
4 -

Is this enought information?

Using a Google link as I said earlier, a z990 307 is 2669 MIPS approximately. You must find out from your systems support group the 5 LPAR weights -- we cannot tell you what these are since they are set machine by machine. If the first LPAR (0 it appears from your post) is 30% of the machine, for example, 30% of 2669 is roughly 801 MIPS.

Unless your site is using LPAR capping, however, if LPAR 0 needs 45% of the machine, and the other LPARs are not using their full weights, LPAR 0 will get 45% of the machine, or about 1202 MIPS. Furthermore, these numbers may be modified by assigning a processor to a single LPAR -- which removes it from the calculations for other LPARs. There are many factors which only your systems support people can help you determine since they are typically coded in places applications people cannot access.

And none of this has absolutely anything to do with an application. Applications are measured in terms of resource usage within the LPAR in which they run. If you have an issue with an application that you think is using too much resource (be it CPU time, tapes, disk space, or whatever) you need to investigate it from the applications side, not from the hardware side.
