Kernel Selection

[Former Member]

Hi

I am installing SAP Netweaver 2004s in a new server where i need to install unicode system. My architecture is like this manner. System A --> AS ABAP

System B --> AS Java BI javaEP but together there should be one database whether it is possible. My solution for this is System A --> AS ABAP + AS Java

System B > BI Java+EP to refer system A.

could anyone guide me how to achieve this both the versions whether possible or not. and moreover

since NW2004s is always a unicode while installing thro the SAPinst GUI sometimes it asks for "Kernel NW2004s SR!" and sometimes " UC Kernel NW2004s SR!" while there are availablity of KN_WINDOWS_I386 and KU_WINDOWS_I386

if select KU_WINDOWS for the both the options what will happen

Hi David

Thanks for ur reply. I am cleared about the Kernel concept. regarding the Installation point of view i have already read in the installation guide (few things confusing) and more over this is our test system.

Has i have explained two scenarios in which you have said the Distributed system is feasible. and the scenario which i have said the SCS+DB in one system and in another Central instance.

But our test scenario ic changed like this :

SYSTEM A :

Distributed Systems --> AS ABAP +AS JAVA --> SCS and Database instance.

AS ABAP ---> AS ABAP ( only ABAP Stack)

and

SYSTEM B:

Distributed Systems --> AS JAVA +BI JAVA + EP which refers to the DB of SYSTEM A.

( Over all one DB should be there in SYSTEM A)

Whether this scenario is feasible.

I have tried this option but while proceeding in SYSTEM A in the AS ABAP --> Central Instance i have faced the following error when profile screen appears

"SAP system BIT is based on AS Java. Cannot remove it."

and then further it is not proceeding. Could u guide me how to achieve this changed test scenario

hi

sorry for confusing u guys i will clearly give the details

there are 2 questions for me somewhat i want to clrify my doubts or concept

1. While installation , in one of the screen it asks Kernel NW2004s SR! so what i should select KN_Windows_I386 or KU_Windows_I386?.

2. MY desired architecture was

System A : ABAP schema

System B: JAVA + only BI and EP

overall there is should be only one DB

by this scenario how to install to achieve this by following methods :

Install SAP Systems->Central System-> Cenatral System Installation in System A and select AS ABAP and AS JAVA and in System B BI Java + EP .

or

Distributed Systems --> AS ABAP +AS JAVA --> SCS and Database instance in SYSTEM A and in

SYSTEM B : Distributed Systems --> Central instance

if iam wrong please guide with step by step so that it will help me in the installation

Hey there Bala,

Some quick answers to your questions - first one is Unicode or Non-Unicode. Doesn't really matter for a test system and if you have a small system to install on (not a lot of memory) then I would use Non-Unicode (the 'N' one). Anything that will be used for supporting a real productive landscape (including sandboxes) - use Unicode (the 'U' one). The differences between Unicode and Non-Unicode are significant enough that you don't want to do any development on a Non-Unicode enviornment to get ready to work on productive systems for proof of concent or anything else like that. For a personal installation for messing around with, you will reduce your memory requirements in the ABAP Stack by half (UTF-16 in Unicode).

As for the way in which to make a distributed or a central installation, that information is in the installation guide for your respective NW intallation that can be found in the Service Market Place - http://service.sap.com/instguides - it is too much detail and information to discuss here only.

Be aware that one Db is supported by both of your scenarios - Central Installation under one SID is one Db - no issues - Distributed under multiple SID's can be two database instances or one MCOD instance. Again more details in the installation guide that would be overwhelming to state in here what all this is. Sorry to push the guide but want to make sure that you get all of the answer you are looking for.

Thanks and if this answers your questions, please set this thread to answered - if not, please provide additional details.

I don't undestand your question.... it looks to me as you're looking more for reasurance than for an answer.

As long as your box have enough resources for all the systems, i can't see an issue... as per the kernel, unicode sounds good to me... i can't see where are you getting confused?
