XI sizing

[Former Member]

Hi,

I am sizing for an XI 3.0 production environment. The parameters we have are as follows:

< 160,000/day sales order create/changes

< 50,000/day records of master data (i.e. prices, customers, materials, etc).

We will need HTTP, IDOC, and RFC adapters with mapping and synchronous processing. The events are real-time and distributed uniformly in 18 hour/day. In the quicksizer I assumed that transactional messages are 100KB and master data messages are less than 200KB. The results from quicksizer indicate volume of almost 6000 SAPS/1200 concurrent users. This is much higher than I anticipate. I am thinking that my assumptions regarding the message size are wrong. Does anyone has ballpark figures for SALESORDER_CREATEFROMDAT2 and DEBMAS message sizes used in production?

thanks.

Hi James,

this is very easy to check in your environment:

2 ways:

a) the easiest one:

go to RWB - performence monitoring on your dev or qa XI

and choose your message

from the you can see the average message size

for one interface - this is exactly what you want

b) the longer one:

go to sxmb_moni on the dev or qa XI

open a few messages (matmas, sales orders)

and take a look at the content of the message,

view - source - save a file... and you have the message size - but this way you cannnot be sure if this is an average size... so the first method is much better

Hi Michal,

Thanks for your excellent response. As we are in the initial stage for deciding O/S and CPU, we don't have DEV or QA installed yet. I am curious about ballpark figures for the sales order BAPI message and MATMAS/DEBMAS records. Greatly appreciate if you can provide the data from your RWB if you have it.

thanks.

James
