How many work processes..??..

Hello Andi!

Don't ask... Just fighting with SAP service who does not
want to accept an ABAP bug for correction... :-((((

Interesting configuration...
My guess is that you will need to increase main storage when going to 4.6c.
We had to jump from 12 GB to 20 GB on our 740 12-way
after the upgrade because the performance was so poor. Be alert!

Kind regards from Austria where the winter has come today
Rudi

Hi Rudi.. how goes it?

we are running an 840 24way 40Gb mem 650Gb Dasd (moving to 1.4Tb in
April 2002)

This will be split into 2 LPARS, 1 being "normal" SAP (FI CO PP MM
etc) & HR

Normal SAP is 3.1I (18000CPW) & HR is 4.6B/Dkernel(2000CPW)

We are looking to support 5/6000 users (about 1000 concurrent)& from
our current config in the 3.1i partition we can only seem to get
72wp's running, any more than that & the system wont start! (any
ideas)

Due to the great power that we can get from an 840 we have
consolidated to 2tier - in Oct 2003 we intend to upgrade to 4.6D, my
estimates then is that we will need about 40000CPW for our normal SAP
system

HR is only a baby & I cant see her growing more than 3000CPW

This machine is then replcated using MiMiX to (currently) an 840
18/24way POD machine

My only concern at the moment is that I may not be able to run a
single instance, but may need to install a few APP instances to get
to my required WP levels.

I'll be interested in the results of your survey....

best regards

Andi
