I have no idea on how to estimate the MIPS MQSeries will use; however, I have to justify MQSeries cost in z/OS as part of requirements. Here's what the starting environment will look like...
Queue managers: Production total - 1; Test total - 1
Persistent Queues: Production total - 15; Test total - 120
Total persistent messages (size * volume):
• Total production messages
Best = 50 bytes/msg * 60,000 msgs per day
Expected = 1K bytes/msg * 100,000 msgs per day
Worst = 2K bytes/msg * 200,000 msgs per day
• Total test messages
Best = 50 bytes/msg * 500 msgs per day
Expected = 1K bytes/msg * 1,000 msgs per day
Worst = 2K bytes/msg * 2,000 msgs per day
Can someone please give me a hand in estimating MIPS for the environment above? Thank you! Mike |

Support Pac MP1B will tell you everything you need to know and more.

A little confused...
Since MQSeries is not installed (that's what I am estimating) how will support pac MP1B help me determine MIPS?
Thanks.

Maybe javagate meant MP1D or MP1E. 
Cheers,

Take a look at this one. This is what I meant to post...
However MP1B is good to have also.
This will help estimate costs

queuetip: I'm afraid, that like in any performance evaluation, especially in z/OS, a theoretical calculation for requirements is simply impossible - There are too many variables, too many specific scenarios, too many exits and configurable options for both z/OS and WMQ. For example:
1. WLM settings.
2. WMQ buffer pools, checkpoints, (all this has a big impact on cpu as well as IO).
3. JES2 or JES3, using any custom-made exits.
4. UOW management, use of CorrlId/MsgId, character conversions..
5. Your WMQ program general design. (dynamic queues, waits etc)
6. Security settings, encryption.
And the list goes on to infinity...
My advice - get a general idea from the SPs mentioned and other sites you may know, but accept the fact that you will probably be off by 50% either way once you get it into production. |

This may be of interest as well...
Select Application License Charges (SALC) is available solely for MQSeries and only on machines with either Workload License Charges or Entry Workload License Charges. SALC is an excellent price/performance option on very-low utilization installations of MQSeries. SALC is available for either Sub-Capacity or Full Capacity WLC/EWLC machines. For an MQSeries installation with the SALC pricing metric, software charges are based upon the utilization of MQSeries.

| Thanks, hopsala. This is my position, too...just getting heat from the infrastructure group to give them something. Seeing a list of items to show goes a long way - if you have other factors still...all the better. I bet I will have to make assumptions on these factor - have any suggestions for reasonable defaults and how I'd do caluculations? Thanks, Mike |

Hm, other than trying make an estimate based on support pacs previously mentioned, I will add these humble suggestions:
A> Give a pessimistic estimate, worst case scenario you'll have some MIPS to spare.
B> Turn to IBM, there's a good chance they will be willing to give you an estimate according to your environment/requirements; this way, your off the hook, and they are bound to their word. It is probable that they have better resources than you to answer said question, as they have thousands of such sites around the world. If you make it clear to them that your going to Buy their product, they will make an effort.
C> Through an acquaintance, friend, an IBM contact, whatever - converse with a fellow MQ Admin who has been working with WMQ on MF for a long while, and ask him what it's like; you might even get lucky - as he's already done a benchamark test last week and has compiled results 
If It sounds as if I'm telling you to try and shift some of the responsibility elsewhere, it's because I am; not an approach I normally or gladly condone, but when asked for the improbable, it's the best one available...
A petite question arises - is this a brand new MF your talking about, or an existing environment? |
