SAP NetWeaver Performance: Parameters

[Former Member]

Hi!

we installed three systems on the same Windows 2003 Enterprise Server 64 Bit.

SAP Solution Manager

SAP NetWeaver 2004s

SAP EP

We have 12 GB RAM, Windows 2006 64 Bit

Now I would like to optimize the storage parameters on ABAP and J2EE stack.

Cann some one tell which parameters are relevant for start annd usage of

SAP ABAP stack (e.g. PHYS_MEMSIZE, ABAP_BUFFERSIZE)

SAP J2EE stack

With which tools can I change the settings?

Thank you very much

Hello Axel,

For J2EE Stack, please refer to the SAP note 723909. You could configure all the JVM related settings using the configtool. You find this tool under j2ee\configtool directory.

Hope this helps,

to set parameters in sap as abap you use rz10 but thats when you know the parameter you want to set.

if you dont you cant do a star find from rz11 get the parameter you want from there and cop and paste it in rz10..then you restart the instance..good luck

Hi,

I hope this is a sandbox system because 12 GB ram is very small for 3 systems with some including abap and java stacks....

Hai,

Normally all the parameters are dynamically set by SAP itself. If you face any problems in the systems while working on it then you have to decide on Tuning parameters according to your error or dumps in the system.

Tuning the storage parameters are not easy, and also they might make the system vulnerable.

Use RZ10 to configure the parameters.

Look into the below link.....
