Assume that there are lot of servers in your landscape and you want to know the details of them like what components have been installed, maintaining RFC connections.It seems to be Gruesome task.. How would you go about maintaining it?

SAP provides an excellent usage called as

SLD

i.e. System landscape Directory. A system landscape consists of a number of hardware and software components that depend on each other regarding to installation, software updates, and demands on interfaces.

Since the data about your system landscape is updated automatically, SLD always provides you with reliable and up-to-date information. Thus, SLD is a central information provider for SAP and third-party tools that use this data to deliver the services that you need to keep your
Landscape up and running.

I would love to give analogies pertaining to it.

Analogy 1

:[start]Assume in the class there are 10 students and the teacher has to maintain their records and handle them and hence teacher appoints a monitor who is one among the 10 students.

Teacher :: Administrator

Students:: servers

Monitor :: SLD

What makes the teacher appoint a particular student as a monitor depends on the students academic performance and etc.

So an SLD server may be a high availability or 8GB ram server. It’s left to the admin to choose one.

we take the same example of teacher , monitor and students. Now the teacher has appointed a monitor of the class to collect the details of all other students. Assume that the class contains students from different parts of the world and they are not able to communicate to the monitor using a single language. How will the monitor communicate with the students?

    Hence the teacher will provide certain converting tools to the monitor to help him to comprehend.The converter would convert whatever the students would communicate into a Monitor understandable langauge.That common language is called CIM and the converter is SLD Bridge. Now if you ask the students to give the details of their home town , house address , name of their dependents, all these students would give it in their format. But monitor will have his on format to collect  the details in such a way that whatever the students would give him he would format it into an understandable format,so that it would be understood by the teacher who would be asking the details henceforth.

Common language :: CIM model

Converter ::SLD Bridge

So to relate, If in your landscape you have AS-JAVA,AS-ABAP and other third party systems, each of them would be giving their own data , now to consolidate and to convert the data so that the SLD can comprehend , we need to Import the CIM model which is a common language. IT also contains the components available in SAP, and Until the CIM model is not imported you cannot list you systems in the SLD.

Now For more updates on SLD Bridge,SLD gateway and how to register an ABAP system and JAVA system in SLD, Kindly refer to my blog Discovering SLD-PART 2

    “hence teacher appoints a monitor who is one among the 10 students”  – Not necessarily..

    In the same way as ur analogy , my opinion is there is no need to have a server with high configuration jus for the sake of SLD.. 8 gb jus bcoz it has SLD.. :o..?

    It would be more informative , if the central HTTP Sld configuration is discussed with its advantages and disadvantages rather than the basic stuff of SLD url etc.,

    The second analogy was nice by the way.. 🙂 ..Will it happen in any school .. i doubt that part.

      First of all, Thanks a heap for posting your comment, I would also agree with you that you dont need a 8 GB ram server, just because its an SLD.

      And regarding the advacned stuff, i would indeed come with those blogs in near future, I just wanted every one ( even those who are new to SAP ) to understand the underlying concepts first and then we can move on to the Intricacies. And also I have the part 2 of this blog following this, I would love to see your comments on that.

    Hi Naveen,

    Thanks a ton for the nice blog. I have so many questions on SLD before reading this blog. Now, I have a basic understanding of SLD. Taking up an analogy for explanation made the blog very interesting one.

    Hope you come up with more blogs.

    Thanks!
    Siribabu G.
