How many work processes..??..
Good morning SAPlings!I'd like to know who runs the biggest instance on an iSeries:
i.e. What machine, GB main, work processes...
Our biggest instance is our general hospital: On a
740 12-way 20 GB main we run a single 4.6c instance (2-tier) with
19-25 DIA, 4-10 BTC, 4 SPO, 3 UPD, 3 UP2, 1 ENQ = 41 WP total
Andi: What is your new machine you try to run your 150 WPs?
And why did you return from 3-tier to 2-tier?
Kind regards
Rudi

Hi Andi,
there is no total limit, but there may 2 problems occur if you are below
4.6x:
- you have care about the problem that a big ABAP buffer will descrease the
possible WPs and vice versa. (e.g. ABAP: 900000, WP: 75 would be too high;
but a bit less works: ABAP 748000, WP: 75 or ABAP 890000, WP: 66)
- you can increase the Extended Memory only up to 8GB, this might be not
sufficient
But, as I read a few minutes ago, that you are on 4.6x, there is no problem
in this area:
You should have a look to note 371029 or 376827, but the essentials are:
The profileparameter:
ztta/as4/roll_shm_cpp_16MB = 5
and at least 4.6D kernel patch 698.
Then you can increase em/initial_size_MB as high as you need!
