Hi frds,

We are using Itanium servers with 8GB RAM. How many work process can be increased for this server.

It depends on th euser activity, if u have a heavy user activity like say if u have 10-20 users and the activity is high from then, then u should have 10 dialog 4 background 2 update 1 enq.

now u do the math depending on your requirements.

Niran.

P.s, allot me some points if i have been any help to you. thanx

Hi,

As per SAP, we can have 50 - 60 MB of memory per work process. So calculate for 8GB memory.

thank u.

well,

from a throughput point of view (benchmarks) the optimum number of wps is depending on the number of CPUs and is about 3-4 wps per CPU.

In real life your primary optimization goal may be different.

On a development system there may be several users locking a wp during debugging session, and therefore the number of wps might be trippel of the one listed above or even higher.

so, the optimum number of wps depends on the usage of the system.

The maximum number configurable is at least 99.

6 dialog, 3 backgrounds, 2 update (v1 n v2), 1spool and 1 enqueue, even for a development system is small. Increase the number of background to at least 5.

4-6 WP per CPU is not valid anymore.

Itanium processor has a power of 800 to 1400 SAPS depending of the model. Plus they are multithreading, multi-core...

One rule of thumbs is to have 1 dialog process for 5 concurrent users. However, some applications consume more dialogs than others (reporting, PI-Sheets,…).

Also, keep in mind that you should limit the number of process per application instance to 50. So, I you plan to have more process, plan to have other application instances.

If you want more information, please give more details (SAP product? Version? Number of concurrent users? ….)

Thanks in advance.

uhu uhu, of course, configure 50 WPs on single-CPU machine and watch 45 of them consumed 0% CPU (in other words - do nothing).

the same is related to number of BGD - only 1-2 of 6 BGD WPs will do real job

Hi,

use 10 Dialog work processes to start with.

if you see too much activity, then use higher value.

[former_member433984]

how many CPUs do you have?

from my experience 4-6 WP per CPU is good value

[Former Member]

hi,

I have only one CPU, but we shd have 4-6 dialog work process? Can we increase update work process.
