What is SLD?
SLD is the acronym of “System Landscape Directory». Is a Java Application running in all the Sap
Java Systems. Is used like Central Information repository of all your system Landscape. SLD use
the Common Information Model (CIM), this is a standard object oriented modeling DB.

Who use SLD?
SLD is used by:
• Process Integration.
PI/XI use SLD like the repository of all the Business Systems definitions, without this
service PI/XI doesn’t run.
• Solution Manager
SM Read the Information from the SLD and refresh the technical definition on SMSY.
• Portal
Used by the JCO Destination.
• NWDI
Identify the role of the system and the Name reservation
• .SLM
Software Lifecycle Management is the tool provide by SAP to make the pacification of you
Landscape.
• NWA
In SLD you can create Groups used by NWA to administrate more efficiently the Landscape.
• ACC
To know all the Systems in your Landsace.

SLD Strategy
The strategy for the SLD is very important, you need to decide in witch way you want administrate
the SLD Information, there are several way and key points(Important, Version, Etc). You can check
in https://www.sdn.sap.com/irj/sdn/nw-sld the SLD paper to develop your strategy. (My
recommendation is read the Planing Guide for SLD).

Access to the SLD
To access to the SLD you can run the transaction SLDHTMLGUI or Goto
http://<sld_hostname>:5<sysnr>00/SLD

Create Landscape
The Landscape definition are used by different applications, Is the best way to group your systems
to Administrate better. You can create Landscape to:
• Administration
which is created for administration purposes, for example, for common monitoring.
• General
which can contain all types of application systems.
• NWDI Systems
that contains servers of the NWDI
• Scenario
is created for a specific business scenario. Scenario landscapes are used in the Software
Lifecycle Manager of SAP Netweaver.
• Transport
is created for transport purposes. For example, all SAP Web AS systems that are connected by an
ABAP transport path distributing the ABAP development.
• Web Service
is created to collect systems offering Web services and their clients. The hierarchy of these
landscapes defines the Web service that is most appropriate for a given client.

<sld_hostname><sysnr>
To create one Landscape go to SLD Main Screen. Goto 􏰀Landscapes


click in “New Landscape”

Complete with the Name and Landscape Type and Create

You can add new Systems to this landscape clicking in “Add System to Landscape..”.

Create your Product/Software
During the implementation phase, you need to define all the technical systems who interact with
you project, to do this you need to create you System/Product/Software definitions.
To create you Product definition Goto the SLD Main Screen􏰀Products. (Remember to check the
Note 1101564 - SMSY: Reading third party products from the SLD)

Click in “New Product Version”..

Complete the information and Click in “Create”

Complete with the Software Unit Name and “Create”.

Complete the component Name and Status and “Create”.


Create Technical System
Is recommendable to create the System in Automatic way using RZ70 in Abap, SLD Data Supplier
in Java or sldreg in other instances types.
If you want you to create manually you need to go to SLD main Screen and click in Technical
System.

Click in New Technical System.

Select Third-Party and Next.

Complete with the System Name and Hostname

Select the Installed Product and the Software component and then click in Finish button. You can
create you own product definition, check the previous chapter.

Now you can see the System in defined in the technical Systems Screen.

View Systems
Goto the SLD Main Screen and click in Technical Systems.


Select one system and in the bottom of the screen you ca see all the technical details for the system
selected

Delete Systems

If you want to delete system, Goto the SLD main screen and click in Technical Systems

Select the System to delete and click in Remove.

View Content Information
If you want to check the Content of SLD, you can go inside the SLD􏰀Administration􏰀 Content
Maintenance

Select the Subset “All With Instances” and BC Systems (our sample).

Now we see the list of all BC Systems defined in this SLD
You can check the Last Modified date to control how updated is the information. Click over one
system to see the details.

You can see all the related information about this instance(You can update this information but
remember that is preferable use automatic update)


If you click in Associated Instances you can see all the relationship with this instance.

Replicate SLD
Is mandatory to understand and create a Policy/Strategy for the SLD in your company. SLD have
different synchronization mechanics:
• Fully automatic synchronization
Only provide in NW 7.1 or higher.
• Automatic Message Forwarding
Using Data Suppliers.
• Data Export/Import.
Manually-Not recommended.
• Using CTS.
In NW7.0 and complex.
Define new Data Suppliers
If you want to update the SLD Information between 2 SLD, you can use the SLD Data supplier.
In http:<sld_host>:5<sysnr>00/SLD , Administration􏰀Data Suppliers
 
Click in Add SLD..

Add the Connection parameter and Save

Now you can see the new SLD connection.

You can check in the SLD Log if the new connection start the replication process.(In this sample
don’t work because we use difference CIM Version ;-)).

Cleanup old systems
Every system in the landscape send all the technical Information to the SLD every 720 minutes,
this is the standard time defined by sap.
If you don’t charge manually information in SLD is a good practice clean the SLD Information to
control the status of the updates in SLD.

Logon to SLD and list all the system, sort by Last Update. You can see few system with old data.

    Hi,

    You wrote :
    "
    Define new Data Suppliers
    If you want to update the SLD Information between 2 SLD, you can use the SLD Data supplier.
    In http::500/SLD , Administration􏰀Data Suppliers "

    This is confusing.

    Indeed, the "http::500/SLD , Administration􏰀Data Suppliers" menu you are refering to, is used to configure the target SLD to which the SLD bridge send the data to.

    To configure the target SLD Brige of the Data supplier, this should be done :
    - for ABAP data supplier : in RZ20
    - for JAVA data supplier : in Java Visual Admin tool :
    /usr/sap///j2ee/admin/go -> -> Services -> SLD Data Supplier -> Runtime -> HTTP Settings

    So SAP would have better to call this sub menu "Administration -> SLD Bridge Target definition", rather than "Administration -> Data Supplier"

    Cheers,

    Steria Dude
