Central SLD/Local SLD
Hello All,
Is there limitation with central SLD over Local SLD?.
To deploy Webdynpro applications (Mobile) please let me know if there are any limitations
Thanks
Hello.
SLD architecture is a long discussion
There are different views on how to set up SLD's.
In my oppinion, the limitations of SLD is that it's a central component to a growing number of netweaver component.
Right now, the portal, webdynpro, xi, nwdi wouldn't work very well without the SLD.
Considering this there is aspects on how to set up the SLD's. Usually critical systems have a local SLD, with supplyer briges to central SLD's.
You would have a separate SLD landscape for Production servers, since they usually run on different SLA (service level agreements).
If you're using NWDI, it's usually a good place to have you're central SLD.
If you're running a smaller landscape, go for the local SLD only and don't complicate your landscape too much.
Check this document (about last slide) with different SLD scenarios. https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/204994f3-0e44-2a10-17b3-808fbd8db4aa

Difference Between Central SLD & Local SLD
Hi All,
Q1) What is the Difference Between Central SLD & Local SLD.
Q2) Maintaining Individual SLD For DEV, QTY, PRD Servers is the Best One Or Maitaining the Single SLD is the Best One ????
Please Ans These Two Q's
Regards
Vamsi> 2. Maintaining individual SLD for DEV, QTY & PRD
> will be better approach. We follow this approach.
SAP recommends a Single SLD.
Having a separate SLD for every environment beats the concept of SLD itself. SLD is a place where you can look and understand what components/ system run in your landscape. If you are going to hve one for every Environment, it is against the concept of SLD itself. More maintenance is another issue.
Single SLD as recommended by SLD has the problem that you do not want to provide access to a component that can be used in production to developing teams and so on .What Barry has pointed is something that is a more practical approach.
There are no hard and fast rules. A client present across Geographies, havinng multiple vendors and IT teams handling different geographies would prefer to have multiple SLD's one for each Geography and then maybe a master SLD that is going to conain all info of the other Sld's and so on., There is no direct answer to this question other than it purely depends on individual clients.

PI 7.1: Central vs. local SLD
We are in the process of setting up a PI 7.1. Our landscape has a central SLD (standalone on 7.00 without any other applications on it).
The PI installation guides recommends to use the local SLD that is synchronized with the central SLD instead of using the central SLD directly.
I remember from some time ago - where we tried to get a synchronization running - that is was not that "easy" and difficult to troubleshoot.
I'm not yet convinced to set up a separate SLD (or more than one for DEV, QA and PRD) instead of having one SLD in the landscape.
Are there any known implications (aside from the inability to use the CTC during setup) when we use an SLD of 7.00 together with a PI 7.1?
MarkusHolà Henrique,
gracias!
We don't use a "classical" cluster scenario but virtualized using Solaris zones (as failover cluster only, not with two nodes).
My question was more regarding functionality with scenarios - are the implications or any known no-go's for running a PI 7.1 against an SLD 7.00? If the SLD is "just" the storage for Technical and business systems and JCos for WD-Java, then it should work

Como pasar un SLD central de PI a SLD LOCAL...???
Hola amigos necesito de su ayuda...!!!!
tengo un SLD central PI entre Desarrollo y Calidad, ya no lo quiero central, lo quiero cambiar a LOCAL
alguno de ustedes podría orientarme para resolver este asunto......???
muchas gracias...!!!Hi Swapnika,
"The SLD is a server application that communicates with a client application by using the Hypertext Transfer Protocol (HTTP)"
Server application is nothing but the SAP server, every SAP server has it's own SLD which can be treated as local SLD. it will use HTTP communication to interact with the Client's nothing but the other SAP and non-SAP systems which are configured in your SLD.
What is Central SLD and what is the difference between Central and Local SLD?
System Landscape Directory Planning Guide
Using Local and Central System Landscape Directories - SAP NetWeaver Process Integration - SAP Library
Do we have to register all SAP and non-SAP systems manually in SLD.
Yes we should register both SAP and Non-SAP systems manually in SLD.
there are 4 types of Technical and business systems in available in SLD.
Web AS ABAP : used for configuring SAP systems like SRM, CRM etc
Web AS Java : used for java systems consist of one or more instances.
Third-party : used for configuring non-SAP systems like Oracle, SQL server, Web-services etc
Stand alone Java: used for java systems that are installed on a system from an administrative perspective.

Migration of local SLD to Central SLD on different host.
Hello Experts,
We have migrate the local SLD existing on the SAP PI System to a new Central SLD on a different host on SAP Solution Manager system.
I followed the OSS Note 720717, which contains the description of the changes that have to be exectued in the SAP XI/PI Environment, during the SLD Migration. This note does not give any details of the description of changes for the other SAP Systems such as SAP ECC, BI etc registered in the SLD.
Can anyone provide the OSS Notes, SAP Doc URL or the steps on how to migrate the local SLD existing on SAP XI/PI System to the new Central SLD on the SAP Solution Manager system.
Thanks for help in advance.
Best Regards,
HaleemFirstly
I recommend to avoid having 1 SLD for multiple clients - like Solution Manager, BI, ECC
This is because clients may end up having conflicting requirements for the same SLD
- for example the small user group for Solution Manager may have a flexible and easy going policy on J2EE downtime
- but if you take down the Solution Manager J2EE that houses the SLD and PI uses this SLD - then you could have a severe affect on PI useage
Secondly
Although you can migrate content - this still does not guarantee the target landscape will work
- you may still need to manually re-implement target landscape configuration
let me give you an example
SLD 1 is being moved to SLD 2
Portal 1 is pointing to SLD 1
Even if you migrate the content of SLD 1 - including the ECC and Portal technical system landscape information
Portal 1 is still pointing to SLD 1 - this then needs to be manually re-pointed to SLD2
and that might not be all the complete steps either !
The complete steps of migration from the client side may not be available (I have found only steps to
migrate SLD content not migrate client use of the SLD)
- they may only be available as the documentation for the original configuration steps required to step SLD and the client
- therefore when migrating SLD you must go through the client setup documentation for SLD and check your
target landscape is consistent
Lastly - other considerations include
Lets say you also export model and CIM content from SLD 1 to SLD 2 - this means SLD 2 has an import line from SLD 1
- if you decomission SLD1 then you need to switch the import line which is not recommended - this could cause severe problems and may require you to create a new import line to upload content from SAP /swdc (which you need to keep the SLD bug free and latest definitions)
Just a few thoughts on issues you may encounter
Best wishes

Local SLD not updating a central SLD
Hi,
In my company landscape, I have
SolMan7.1 with Central SLD (Let's call this SLDA)
Portal 7.02 with local SLD (Let's call this SLDB)
ECC6
Both the Portal and ECC systems are updating SLDB, so I can see both technical systems in SLDB.
SolMan is updating SLDA, so I can see SolMan technical system in SLDA.
I linked SLDB to SLDA via
From SLDB> administration> data suppliers --> add SLDA
For this setting, I use the user SLDDSUSER, which have a role LcrInstanceWriterAll.
The problem now is SLDA does not get the data from SLDB. In SLDA, I see only the SolMan Technical System.
How often does SLDB update SLDA? Can we manually trigger an update SLDB->SDLA?
How can we troubleshoot the SLDB -> SLDA update?
What else needs to be configured other than "From SLDB> administration> data suppliers --> add SLDA" ?
Thanks
Edited by: Nick Foo on Sep 27, 2011 3:53 AMHi Sunny,
yes I have done those steps. Very short and easy setup steps to link to another SLD.
OK, just one thing to confirm here.
After Add SLD, the SLD URL syntax should be http://host:port correct?
I have tried all sorts of entires for the URL
http://host:port
http://host:port/sld
http://host:port/
All not working
Checked the user, user is ok, even tried giving the user Administrator role and still not working -
Hi,
We are planning to install a NW2004s system for the use of EP. During installation we had configured the system to use "Local SLD". How do we configure this system to use our "Central SLD" ? Please point to some documentation.
Cheers!!Hi Rao
I will tell you few steps to hook ur EP system to Centrel SLD.
1.Go to visual administrator of EP( java system)--instance-serverservices-----SLD data supplier
2.Put the details of ur centrel SLD there in http settings.I mean the server name,user who has admin rights for ur central sld.
3.Click on the save button.
4.Perform the same steps in CIM client generation settings
5.You can check ur configuration by clicking on CIMClient Test.
6.If everything is correct ,you will get successfull pop up window.
7.Then trigger the data transfer by clicking a blue colour arrow.This will trigger ur EP data to the central SLD.I mean they both can talk now.
8.Then you can also go to ur central SLD,and search for your EP instance,it will be listed there.
In case you face any issues let me know.

Local sld pull from central sld
We are in the process of configuring a brand new sp19 solution manager server. We have a central sld on a dedicated server with several systems already registered on it I created a local sld on the new solution manager server. I want to pull the systems from this central sld server into the solution manager server, but cant' seem to find any documentation on how to do it.
I've read the SLD planning guide, the sld post-installation guide,, and the sld user guide. If there are any steps that document how to do this, I've missed them.
Can anybody help?
--CarlOn your central SLD: Administration -> Data Suppliers -> Add SLD...
Type in URL, valid user and pass and that should be it. It works this way on SLD based on NW70. -

Regarding Central SLD and Local SLD
Hello,
Can we maintain Central SLD as well as Local SLD?
We have maintain central sld during installation , now i want to maintain local sld also.
How can we do this? what is the benifit and disadvantage for maintaing both?
Regards,
V.SinghHi V.Singh
You can have as many SLD as you like - the service is available as part of a WAS JAVA install
Bear in mind the more SLD = the more administration and if you wish to sync them there is also many considerations
It is best you check the SLD planning guide at System Landscape Directory (SLD) to select the landscape that
best suits the intend use
The Central SLD concept is primarily to have an SLD containing all systems in your company i.e complete overview - this might not be specifically used for runtime of these systems - say PI useage etc - it might be used to populate Solution Manager with landscape data or just track all systems and changes in the organization
The central SLD concept is also not essential however an SLD (a local or app specific one) is essential for certain applications like PI, ESS etc
