EREC: Question concerning system landscape

Hi all,
I'm looking for someone who has excperience with a systemlandscape like this:
development-system: one frontend-system and one backend-system
quality-system: one frontend-system and one backend-system
produktive-system: one frontend-system and one backend-system
training-system: only one system (backend=frontend)
The customer has no transport connection between the frontend- and backend-systems. There are transport connections between the frontend systems and the backend systems.
The question is: which transport requests go into the training-system? Do we have a problem, when the frontend- and backend-transports go into the training-system?
Thanks in advance!
Regards
Chris

Hello Chris,
first of all I am a bit confused why there is no connection between the frontend and the backend systems. The best practice approach for implementing an e-recruiting project with frontend / backend separation is to do all customizing and development on the dev backend server and then transport to the dev frontend system to ensure th systems are in sync. Parallel customizing and development in frontend and backend is not adviced.
In general the training system should have the same system architecture as all other eRec systems in the landscape. This way even if there are customer developments which have been done in a way that only supports your project landscape instead of supporting all possible eRec landscapes (integrated / standalone, frontend / backend separation, ... ) they will work properly on training. Furthermore the system setup will be the same.
Of course it could work if you use a training system without frontend / backend separation if this has been thoroughly planned during the project. If you can ensure that all developments have been done in a way that they support this landscape this should work. Special in your case, if you have really implemented in parallel on frontend and backend you must have applied and tracked sufficient naming conventions to prevent any conflict in development objects when they are combined on one system. (As the effort to implement the required processes and tools to ensure the compliance to such development standards is usually exceeding the costs for a small separated training frontend server having the training landscape aligned to the other systems landscape is the bst solution).
Kind Regards

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

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.

Quick question on BOE deployment for SAP BW with 3 system landscape

Client has SAP BW environment with 3 system landscape: Dev, QA, Production
Should BOE be installed seperately on 3 different machines for each of them?
Or is there any best practice for this?
Thanks,
Henry

Hello Henry,
yes - i would recommend this Setup. Technically there is no need for it but on an organisational/development/deployment level it makes more sence.
I often saw it at customers that Dev and Q&A is on virtual machines and Prod is on a physically machines. Saves some Hardware costs.

EREC E-recruting DMZ landscape

Hi
We are designing an E-recruiting system, which should be used for external candidates.
We are planning to use the webdynpro interface technology and has decided to split the 'frontend' and 'backend' into two systems - running the 'frontend' WebAS ABAP system in the DMZ.
When having a look of SAP's online documentation
http://help.sap.com/saphelp_rc10/helpdata/en/2c/95c241979ac417e10000000a155106/content.htm
...and will probably go for the technical system landscape at the bottom of this link (above).
Our question: Is the any reason for having a separate reverse proxy/application gateway (like SAP web dispatcher) in front of the 'frontend' system in the DMZ (as indicated in the link) ?

Hi Roman
Thanks for the advices.
Do you have any specific reasons for not recommending the last ("Front-End and Backend on Different Systems (SAP E-Recruiting Integrated with ERP)") solution with the EREC backend in the HR system?
Reasons: Security, flexibility, performance, availability, manageable?
This alternative is attractive from a cost perspective, as one less system (SAP, RDBMS, OS etc) is needed as if the backend should also have its own WebAS ABAP system.
Another alternative with only one extra system for EREC would be the frontend and backend in the same system hidden by an application gateway in the DMZ. This has some advantages
- Only one extra system for the EREC project (per environment of cause)
- Frontend and backend customising/development in same system (in same net as no frontend in the DMZ)
- EREC can be patched/maintained independent of the HR system
- but... Any security issues having the EREC system (frontend+backend) on the same net (not in DMZ) as the HR system?

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:

Good afternoon ladies and gentlemen!
My question concerns the impossibility to open RAW-files directly from the program Adobe Bridge. At the moment when you open a RAW-file from Adobe Bridge by double-clicking, RAW-file is opened only in Photoshop. In the settings Adobe Bridge - in "open RAW-files by double-clicking in Adobe Camera Raw» box is checked. When you try any changes in the settings Adobe Bridge system displays a message:
Bridge's parent application is not active. Bridge requires that a qualifying product has been launched at least once to enable this feature.
The entire line of Adobe products on my computer updated to the latest updates. Previously, a family of products Adobe Photoshop on your computer is not set. Computer - PC, Windows 7 Enterprises.

Is it possible to do portal content transports through System landscape?

Hello,
In order to transport content from portal A to portal B I am currently using transport packages: export the content from portal A, download it to the local PC and import it to portal B. The process is working OK but I still have a question:
SAP are transferring all the control on their systems to the System landscape, for example Java developments. My question is if it is also possible to make these transports through the system landscape so no local PCs are involved in the process?

Hi Roy,
You are right in the point that development projects can be transported, using the NWDI, centrally managed through the system landscape.
Nevertheless, the PCD transports (EPA) have to be touched manually anyhow. Theoretically, you can set up an SDA and put an EPA into it, see http://help.sap.com/saphelp_nw04/helpdata/en/a3/782240da03e569e10000000a155106/frameset.htm for details.
But this only really makes sense if you want to transport your own application together with the portal configuration (iViews representing your application...).
So in the end, PCD transports are designated to be transported as you are used to - manually via the export / import function of the portal.
Hope it helps
Detlev

System Landscape directory not available error,

I am still a beginner, and I am having some slight trouble understanding, what tools would be needed, and how to install. I am using the forums.
We have the MII Discovery Server up and running.
NWDS Server installation is done.
We have the MII track ready to be used for Development(SLD URL is available) , Userid and password available
I am working on installing the NWDS 7.3 Developer Workspace.
Would I also need to do NWDS Server install on my laptop?
Would these steps be sufficient?
1. Download and install JDK 1.6
2. Copy the file nwds-extsoa-7.3-SP00-PAT0000-win32.zip from:
<your download location>\51039309\DATA_UNITS\JAVA_IDE\distros\com.sap.netweaver.developerstudio.distribution.complete.extsoa\8.30.0.101020102100
to a convenient folder.
3. Extract the content and you will have a folder with name eclipse.
4. Launch the Netweaver Developer Studio from folder eclipse, you may want to create a shortcut on the Desktop.
5. If you haven't maintained JAVA_HOME property or if it's pointing to some other java version, eclipse will complain about it. In the dialog window locate the JDK 1.6 installation. Path to JDK 1.6 should be something like
C:\Program Files\Java\jdk1.6.0_25\bin
6. Restart the NWDS after this and select a suitable workspace.
7. Set the run time engine in NWDS, by going through the menu path:
Window->Preferences->SAP AS JAVA
Question:
1. I am unable to Set the run time engine in NWDS, please could you give me details steps with what I would need to enter for Instance Hostname and Instance Number...etc
2. As part of Development installation do I have to Modifying the Logon Page? Do I have to go thru the Server installation in order to start developing on eclipse environment?
I do not have the war file. How do i Copy the war file tcsecumelogonui.war from
<Installation drive>:\usr\sap\<SID>\J00\j2ee\cluster\apps\sap.com\com.sap.security.core.logon\servlet_jsp\logon_ui_resources\tcsecumelogonui.war
3. System Landscape directory not available error,
In the Component Browser when I right click and select New u2013 Development Configuration u2013 Import From System Landscape Directory (SLD) u2013 Next (Enter UserID and Password)

Might go for T400/500- Many questions concerning Think Vantage

Hi,
I am deciding on my first IBM, a T400 or T500
I have a few questions concerning the Think Vantage Function:
a) Does the recovery DVD set back the hard drive partitions to factory settings?
b) Does the Think Vantage function set back the hard drive partitions to factory settings?
This means the original size of the partitions, when they have been changed manually.
c) Does Think Vantage work with a self buyed Windows Vista?
d) Does Think Vantage work unter Windows XP
e) Does Think Vantage need drivers/ anything else to work or is it entirly working on the hardware side, so no software/ windows is needed
f)Will Think Vantage work under Windows 7 in a T400/500
g) How was the past situation? Did a under Windows XP working Think Vantage also work on Vista / have there been drivers delivered, when needed, for the new OS
h) Is it possible to set up a new OS (like Vista Ultimate) and then backup it up on a external hard drive and later recover from this?
What do I want to achieve?
I want to recover the factory settings at all times, this means partition size, number of partitions etc. and Windows Vista Business. Then I want to install Vista Ultimate do my settings and backing it up to an external drive or whatever and then recover from that all 3 Months. In the end I should be able to set back factory settings with the earliest/ first backup from Windows Business; Furthermore I might want to install Windows 7 sometimes.
Thank you for your help! Kind regards

Client Roles in a Three System Landscape

I initially post this Question in other forum:
Hi all,
We have a three system landscape. In the Development client, we have the Customizing Client, the Sandbox Cliet and a Training client. I have some questions about this configuration:
Acording to System and Client Settings - System Administration Assistant (BC-RRR) - SAP Library, Training client must be in Quality Assurance System, and it must be created by client copy from client QTST (it gets the transports from Custimizing). In this Training System we must create users for all our key-users to training. We must not create any user for key-users in sandbox client (this client is for the DEV team). is that ok?
What are the downsides of having out TRAINING client in the Development System?
Now, a consultant is asking me to open some modifications in the TRAINING client: He needs to load Exchange rates (OB08) in that client, but he is getting "Client is not modifiable". They are asking me to create users for key-users in the sandbox client and the training client.
I need to know if they are using the system in the right way. I dont want the system to become a mess.
I been reading this notes: SAP Note 356483. I don´t know what this means: "Now the corresponding Customizing object is no longer subject to the transport connection and is excluded from the changeability check. The change is active in all clients of the system. You can also change the Customizing object in a locked client (independent of the client role). However, now it is also no longer possible to manually transport entries of the view or table."
Aditional notes:
SAP Note 78329, sap kb 356483
Thanks for your help!
One person answere me this:
Hi
You should create your question in the appropriate area :
Software Logistics
The drawback of having training client in dev system is that it could be negatively impacted by ongoing changes performed in that system (custom program that are changed, not working...)
Some specific customizing changes can be set as current setting and thus can be modified without needing to open customizing but only if the client is set as productive.
There is also a way do deactivate modification recording of objects (aka deactivating the transport connection) but, if you apply this change for this activity/object, you won't be able any more to record change into transport orders
Regards
356483 - Customizing: Current settings in the test system
77430 - Customizing: Current settings

Hi Andres
I do not really now the exact impact, it might prevent some business data from being mass processed or overwritten...
I did had to deactivate the transport connection on specific objects/activities for some customers.
It depends on the frequency of that activity. I don't like to open the client to modification as you can sometime forget to close it back, and sometime also it gave the opportunity to other consultants to make changes that would create inconsistency among envt in the whole landscape.
At least activating the recording of changes could help in tracking the source of modifications
RZ10 => rec/client=ALL
STMS => RECCLIENT=ALL

How to deal with customer motive in three system landscape?

Hello,
I am developing a portal application based on the Composition Environment 7.1 in a three system landscape. Now, I have created a customer motive on the development system.
What is the proposed way to transport this motive from the development system to the quality aussurance and the production system?
Is there some sort of transport mechanism or do I have to export / import the motive?
Best regards
Alexander

Hello,
Portal themes can be moved use the theme transport tool. From system admin -> portal display -> theme transport there is an option to store a theme as a zip file and then you can upload it to another portal.
I know that this is possible. My question is, whether this is the preferred (or intended) way to do this.
Best regards
Alexander

System Landscape Directory is not accessible

I am trying to get my end to end monitoring working but every time I try to log in and display it asks for a user and password and no matter which user I try it tells me i have no authorisations...
So someone suggested that I goto /nwa to implement the template...
When I go there and put in the user and password it comes up with System Landscape Directory is not accessible.
Does anyone know why this is? or what can fix it?
NOTE: It is worth mentioning that the SLD can be accessed by the IR and ID... and I can go on to the SLD directly so I don't understand this issue...

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.

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
