System landscape information

Hi,
I got an email from support team with few questions on system landscape. If any idea can you please tell me how we can find the following information at SAP GUI level?
System landscape:
- Is it a Integrated or a external installation ?
- What is your current system status(kernel basis)
- Is it a single or a dual host installation ?
- Which operating system is the ITS running on?
Thanks in advance
Regards
Srinivas

actually I got this mail from support team hmmz. But I think your answer will be fine.
What about ITS single or dual installtion? how we can tell that our system ITS is single or dual?
If any idea please tell me.

Information on 3-System Landscape for XI

Hi All,
Currently we have DEV/QA XI as one system and Prod as another. We plan to seperate QA and have a 3 system landscape for XI... ie, DEV, TEST, PROD.
My Question is
> Any documents on what are the system requirements in doing so?
> Is there any advantage/disadvantage in doing this?
Pavan.

The sysetm configuration might be 2Gb+ Ram with good storage of Harddrive....there can be problem when you have both the dev and QA system on the same server or same instance with dfiferent client......
It;s better to have the Different system for DEV,QA and Production but as far as SLD is concerened standard says to maintain the single SLD but for production it will be good if kept seperate SLD.

Information broadcasting system landscape

Hi,
Can you let me know, what is best system landscape for IB?
Can you let me know which option is good on production environment?
1) We are planning to install Pre Calculated service on production application servers. We don't want install Pre cal service on database server.
2) Install pre cal service on standalone server without application server components.
Thanks

This will depend on the load you are expecting for the Pre-calc server, if your app server is running on Windows environment you have the option for running the pre-calc server also on the same server. But it will be better to seperate the the Pre-calc server and install it on a standalone windows server. Under "normal situations" 1GB main memory on a 1 Ghz machine sufficient, but as I already said the need for resource might grow when more heavy workbooks are precalculated.
Thanks.

SOLMAN 4.0 SR2 connect to SAP R/3 Three System landscape (DEV QA and PRD)

Hi,
We have successfully installed SOLMAN 4.0 SR2 (ABAP + JAVA) on
WIN2003 SP2 EE MSSQL 2005 EE SP1.
I just want to activate the service so that SOLMAN could see my existing SAP R/3 4.6 C Three system landscape (DEV QAS PRD).
I heard settings should be done on SPRO IMG configs. Could anyone tell me the exact procedure to navigate on it. I see a lot of buttons to config and execute, Just want to make sure everything will be in order.
My SLD is directly installed locally on my SOLMAN server.
Thanks,
Simoun

Hello Simoun,
Telling from your last sentence I assume that you would like to connect SolMan (transaction SMSY) to your locally installed SLD or in other words: replicate SLD system data into SOLMAN system landscape SMSY.
Please check this document:
http://service.sap.com/~form/sapnet?_SHORTKEY=01100035870000538663&_SCENARIO=01100035870000000202&_OBJECT=011000358700000530282007E
Here you find information covering prerequisites, required SAP Solution Manager IMG configuration to connect SLD and SMSY and frequently ask questions (FAQ-like).
I hope this helps you to get started.

Doreen

Doubts in System Landscape Directory

Hello All,
I got some basic doubts in SLD.
Why do we need to store the information about the installed products and to be installed products in software catalog?
And, what is this techncal system?
After reading few help sites, what I understand is the following:
For example SAP is a product and CRM etc are the software components. We create the technical system for this product like for client 100 we create a technical system and for client 200 we create another technical system. And we give some logical names, called business sytems, to these technical systems.
My second question is, why do we need to create all these information(the information in SLD)? Why cant we directly create messages types, message interfaces etc and configure them in Integration directory without using the information in SLD like business system?
In Integration Directory, we say that the sender is one Business System and receiver is another business system. These business system are created based on some technical systems. These technical systems are based on some software components and product. This product and the software component might be a installed or non installed product. Then how do we can get the connection between the sender and the business system? Can you please explain me the idea behind considering the sender and reciever as business systems.
Can anybody please clear the above doubts?
Priya

Hi Priya,
SLD:
The System Landscape Directory of SAP NetWeaver (SLD) serves as a central information repository for your system landscape. A system landscape consists of a number of hardware and software components that depend on each other with regard to installation, software updates, and demands on interfaces.
- so talking about the working of an SLD, here if any information is required for the integration server regarding the systems(logical or physical) and the software (installed products) it refers to the SLD.
- to tell you about the other features it has....it captures the dimensions of the system landscape like solution dimension, transport dimension and technical dimension.
- putting it in short XI IS A CLIENT OF SLD
Also go thru this link and understand more about SLD <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/31/f0ff69551e4f259fdad799a229363e/frameset.htm">System Landscape Directory</a>

SOFTWARE CATALOG:
The SLD contains a Software Catalog of all installable SAP products and software components. The Software Catalog includes information about support packages and dependencies between the products and software components. This information is the basis for the description of the system landscape.
Also go thru this link and understand more about Software Catalog <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/a2/2999ef97ea2b4790165f9ca5c05c41/content.htm">Software Catalog</a>
TECHNICAL SYSTEM, BUSINESS SYSTEMS, SOFTWARE PRODUCTS:
Technical system correlates the software to the physical host on which it is installed
Or in other words Technical systems are application systems that are installed in your system landscape.
- they are actually the basis for defining the business systems.
- we assign a technical system to a business system to help the SLD make the appropriate association.
- the software products used by the business system are got from the technical system definition.
- to note 1 technical system can have more than one business system assigned to it....and as told the SLD make the appropriate association between them.
Also go thru this link and understand more about each of it:

System landscape planning on system i

Hi,
We have V5R4 latest AS/400 Model with 2 LPARS(Logical Partitions).Each LPAR consists 2 TB storage and 30GB RAM.
a) LPAR1 - 2TB Storage ( SB,TA,DEV,QAS) :
b) LPAR2- 2 TB Storage for Production (PRD) + HA- High Availability
Our initial plan is All Solution Manager Instances B,TA,DEV,QAS), ECC6.0 Instances
(SB,TA,DEV,QAS), Net Weaver 2004s instances (SB,TA,DEV,QAS) install on LPAR1.
Each LPARS consists 3 iASPs(Auxilarlly Storage Pool).
ASP1- SYSBASE stores all Instances(Solution Manager,ECC6.0,Netweaver 2004s) Files Systems like /usr/sap/SID-SB,TA,DEV,QAS.
ASP2- Journals : Stores all instances(Solution Manager,ECC6.0,Netweaver 2004s) recent databse changes.
ASP3 - Libraries storesStores all instances(Solution Manager,ECC 6.0,Net weaver2004s)Database informations
But We are planning to implement 2 iASPs in LPAR1 ( DEV/TR/QA )
a) ASP1 - Sysbase + journals
b) ASP2 - Database
what approach would be best for our SAP system landscape environment.
Thanks

Not quite, Nesimi
The planning guide is clear: For each data supplier, you need a dedicated user in the central SLD.
What I do not understand is why. Why can't I get away with using the SLDDSUSER of the central SLD for all data suppliers? What difference does it make if I have a dedicated user for each data supplier in the central SLD?
I have 10 systems to send data to my central SLD and I want to avoid creating 10 different users, if it can be avoided

URGENT: Changing System Landscape in ChaRM

Ok...here is our situation:
We use ChaRM with a 3 tier system landscape (DEV > USER > PROD).
Out USER system has been down for a month (maintenance) so we went live with ChaRM as follows:
DEV > PREPROD >PROD
Our USER system is now back up and running so we have replaced the Logical Component on the project to reflect this. This has worked ok but the task list is still showing the old system landscape. i.e. its showing PREPROD still instead of USER. How do I resolve this?
Do I have to complete the existing cycle and then create a new one? This would be fine except I would lose all the jobs I have scheduled in the task list (schedule every 15min EVERY day....took me ages).
Any suggestions?
Thanks!!!!!!!!!!!!

Hi,
About this issue, there is a detail information about this in blog point 6 u201CChanges in the logical components of a project where Charm is already activatedu201D.
This is the link: http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/15116
So, you have to change the transport route accordingly and then close current maintenance cycle and generate a new one.
Following is the steps.
1: please import all the transport requests which were associated in the current maintenance cycle task list by STMS manually import.
1: change transport route from DEV > PREPROD >PROD to DEV > USER > PROD on the domain controller system.
2: close current maintenance cycle.
3: change the system landscape to DEV > USER > PROD in solar_project_admin.
4: generate a new maintenance cycle.
Thanks

No access to system landscape at present

Hi
I am trying to establish connectivity between ECC and PI. I am in SXMB_ADM of ECC and under Global Configuration Data, I put the role of business system as Application System. Now when I click on the Systel Landscape, I am getting an error " No access to system landscape at present". How should I solve this?
What do I enter next to corresponding Integ server ?
Regards

Hi,
Check in SLDCHECK, from R/3 side, if everyhting is ok.
You may want to check:
#1143810 - Troubleshooting SLDCHECK - Releases 71X
Second point, check note below to about the components in SLD, if they are correctly registered.
#1334053 - No automatic PI 7.10 SLD Registration
And take into account the following notes mentioned in the note above:
#1117249 - Incomplete Registration of PI components in SLD
#764176 - Error in XI due to inconsistent SLD contents
Last recommendation, open the Exchange Profile and change all parameters that ends in *.name to FQDN, and don't forget to restart the system to activate the changes.
For more information about the FQHN, check the notes below:
#773830 - FQHN determination in ICM
#654982 - URL requirements due to Internet standards
Also ensure to apply the FQHN as per instructions on the note below:
#804124 - HTTP communication with XI Adapter Engine fails
And check for the parameter 'com.sap.aii.connect.integrationserver.sld.name' from note:
#1278563 - Specification of message server host in Exchange Profile

What is the Three System Landscape in SAP

Hi All,
Please explain me What is the Three system Landscape in SAP.
Thank you very much,
Kavya.

1. Database Layer
The database layer consists of a central database system containing all of the data in the R/3 System. The database system has two components - the database management system (DBMS), and the databse itself. SAP does not manufacture its own database. Instead, the R/3 System supports the following database systems from other suppliers: ADABAS D, DB2/400 (on AS/400), DB2/Common Server, DB2/MVS,INFORMIX, Microsoft SQL Server, ORACLE, and
ORACLE Parallel Server. The database does not only contain the master data and transaction data from your business applications, all data for the entire R/3 System is stored there. For example, the database contains the control and Customizing data that determine how your R/3 System runs. It also contains the program code for your applications. Applications consist of program code, screen
definitions, menus, function modules, and various other components. These are stored in a special section of the database called the R/3 Repository, and are accordingly called Repository objects. You work with them in the ABAP Workbench.
2. Application Layer
The application layer consists of one or more application servers and a message server. Each application server contains a set of services used to run the R/3 System. Theoretically, you only need one application server to run an R/3 System. In practice, the services are distributed across more than one application server. This means that not all application servers will provide the full range of services. The message server is responsible for communication between the application servers. It passes requests from one application server to another within the system. It also contains information about application server groups and the current load balancing within them. It uses this information to choose an appropriate server when a user logs onto the system.
3. Presentation Layer
The presentation layer contains the software components that make up the SAPgui (graphical user interface). This layer is the interface between the R/3 System and its users. The R/3 System uses the SAPgui to provide an intuitive graphical user interface for entering and displaying data. The presentation layer sends the users input to the application server, and receives data for display from it. While a SAPgui component is running, it remains linked to a users terminal
session in the R/3 System.

System Landscape Directory is not accessible on NW04 Sneak Preview

Hi,
I installed Netweaver sneak preview Full Java edition on a server and when i access the NW administrator at the url http://...:50000/nwa.
In "Overview" of system management there are 2 warnings :
System Landscape Directory is not accessible
and
Only local system can be administered
But SLD is working i can assess it on http://...:50000/sld
Can anybody help me ...?

Hi,
NWA works out of the box for the local Java stack. No SLD needed. Its just an information.
The second flavor of NWA is to act as a central monitoring tool. In that case, some things have to be configured (e.g. the connection between NWA and the SLD). Information about that can be found in SMD service.sap.com/nwa, or probably here

Related to System Landscape of XI

Dear All ,
I have a query related to the structure of system landscape of XI in the implementation project .
Do we create two clients for Development and QAS on the test system or we create just one client for Development and QAS ?
Thanks & Regards
Prabhat

Dear Udo ,
Thanks for the information but my question is somewhat related to client's creation on XI server .
As we know Development , Quality and Production sytem exists in normal system landscape .
Now I am putting Development and Quality on one XI server and Production on the another .
Keeping this in mind do I need to create 2 client's for Development and Quality or we should simply create one client on XI server which will work as development as well as quality client ?
Thanks in Advance
Prabhat

System Landscape on XI or SRM ?

Hello to all,
Actually I have to configure the system landscape for several systems, but I do not know which are the best practices that I must follow to form it.
I have two servers one of the XI and other one of SRM 5.0, additional I have in another server of SSM 3.2.
Would I like to know which is the best recommendation, if I must install and configuring SLD in the XI or SRM?. And if someone can indicate me where it he can access information that recounts me to this topic.
I have never formed the SLD in Systems SAP, estimated to anybody who could orientate me.
Best Regards,
Desiree

Hello Desiree,
A good approach is to use the SLD for your Solution Manager 4.0, by using this SLD as primary one, you can release the resources for the others Application Servers and also use this for change management reporting....
Of course it depend how critical is your XI and if your system have sufficient resources.
BTW, if you don't have a Solution Manager you must install one as soon as possible or at least use the SM Diagnostics as stand alone cause it's very important for root cause analysis on Java based product like your XI.
Hope this helps.
Yours,
Luis

System Landscape security

Hi,
We have a system landscape having systems based on Java stack(EP,BI Java), Java+ABAP(XI,SRM) stack and ABAP(ECC) stack.
We have Windows Active Directory as the LDAP server.
We need to implement a security concept for the entire landscape.
Requirement is to use single sign-on and LDAP. We also want to use Windows integrated authentication.
Could someone please answer the following questions:
1.Recommended data source for users and role assignments?(LDAP,ABAP,UME).
2.Can/Should CUA be used to manage the users of Java stacks?
4. Any other recommendation / learnings?
Basically, I need to know an optimal/tested solution for implementing security in such a complex landscape.
Thanks.

Rohit,
If you go to https://websmp207.sap-ag.de/security and navigate to 'Security in Detail' on detailed navigation, you will find relevant information.
There is also a security guide on /NW2004s. Related documents you can find at

System Landscape for ESS/MSS in EP60 SP2

I have installed EP60 SP2 on J2EE 6.20 and MSSQL. I have imported business packages ESS 50-4 and MSS 60-1-5. I have created the folder Systems in Portal Content and created a system SAP_R3 with aliases SAP_R3_HumanResources, SAP_R3_Cross, SAP_R3_Travel, and SAP_R3_Financials.
My 4.7 R/3 system is app server R3DEV02.domain.com, system id DEV, sysno 01, client 100. My ITS server is http://itsdev01.domain.com:71/scripts/wgate/webgui/! using client 100. My EP path is http://sapport01.domain.com:50000/irj/.
Given this information, can anyone tell me exactly what parameters I must set in the system landscape for system SAP_R3 and what the values should be for ESS and MSS to work properly? If I go to the System Landscape Cockpit, system SAP_R3 fails all tests.
Any and all help is certainly appreciated.

Hello Gary,
WRT SAP_R3 system landscape test failure, I ran into the same issue earlier, for a SAP_R3_Dedicated system. Keep the same setting values, but leave the system id (DEV) Blank, then test.
Your definition of (Application Server Host Address + System Number) should be sufficient for a SAP_R3_Dedicated connection.
I hope this will resolve your system TEST problem.

AAAttar
