SAP NW ABAP 701 SR1 TRIAL - Performance Issues

Former Member
0 Kudos

Hi guys,

I'm a BW consultant and thought i would have a go at installing the SR1 trial. Specs are as follows:

VM XP SP2

1 Processor, 4 Cores @ 4Ghz

3GB allocated (out of possible 4GB)

The main purpose of this build is to create ABAP function modules and classes and ofcause BW. The system memory doesn't appear to be fully utilised, usually 30% while all 4 cores hover around 20% while creating an InfoPackage.

The tasks that take the logest time a gernally when the system states "Compiling XXXXXXX in a separate task".

Can anyone suggest some settings that i can look at in order to better utilise the resources of my computer?

NB: I'm planing on buying another 4GB of ram and moving to Windows Server 2003.

Hi Paul,

The tasks that take the logest time a gernally when the system states "Compiling XXXXXXX in a separate task".

You can get rid of the compilation issue by kicking off an SGEN process (takes a few hours depending on the speed of the machine).

For the memory settings, you can generally take the total memory given to the VM and split it into thirds. Give one third to the DB and two thirds to the application server (i.e. your PHYS_MEMSIZE setting).

Hope that helps.

Hi Joe - many thanks for the response. I already have a specific thread going with regards to memory and have already set the PHYS_MEMSIZE to 2000mb but SAP is still paging up to 4GB whilst the actual physical memory stats suggest that the server is still only 1/3 utilised

I'll post some screen shots shortly.

Thought it might be useful to also post total memory settings:

Please can someone advise?

Hi Experts,

Have run SGEN and things are allot better now. With regards to this statement:

"For the memory settings, you can generally take the total memory given to the VM and split it into thirds. Give one third to the DB and two thirds to the application server (i.e. your PHYS_MEMSIZE setting)."

Can someone tell me how to allocate DB memory? I can't find the setting in ST02, ST06, RZ10 or DB02.

could not check your screenshots as they are not visible. But see if following helps you.

- Swap memory on operating system 2.5 to 3 times of your RAM

- /3GB switch in windows boot.ini file

Thanks Manoj,

I assume that you are talking about this [article|http://technet.microsoft.com/en-us/library/bb124810%28EXCHG.65%29.aspx]?

Note, you need to click on the links I have provided to see the screenshots. Just tested the last couple and they are working

As i thought, looks like the memory is not really being utilized. I think i only have 1 dialog available as well?????

Can someone please interpret these stats and provide advise with regards to how i can better tune my system.

BTW: I'm aware that maxdb should be on another disk but i have no idea how to move it?

Hi all,

I have managed to fix allot of my performance issues by increasing the dialog and background processes, previously 1 & 2 respectively! I have done this by using transaction RZ04, clicking on instance DUMMY, and then changing the allocated values. My current setup appears as follows: http://img156.imageshack.us/img156/6437/performance5.jpg

I am however still at a loss with regards to changing the PHYS_MEMSIZE. Also, as i am running a VM, i have allocated 3GB to the VM leaving 1GB for windows 7. I assume that within the VM i will need to allocate 1GB to the XP PRO SP2 OS leaving a PHYS_MEMSIZE of 2GB?
