Hi Keerthi,

Technical Systems are of following types:

1.)WEBas java,

2.)Standalone JAVA

3.)Third party

4.)Web as ABAP

1) Web AS Java

Web AS Java systems consist of one or more instances and each instance is installed on a separate host. An instance itself consists of cluster nodes that can communicate with each other.

2.)Standalone Java

Standalone Java technical systems are standalone Java applications that are installed in a computer system from an administration perspective. They can also be installed as an operating system service or as a daemon

Web AS java belongs to the NetWeaver [Comes with both ABAP and Java], Standalone instread comes separate from the netWeaver.

3) Third party technical sytem

It can be any of the technical sytem. let us say if you want to send a file to R/3, here the file reside in your local system. for that you can define your local system as a third party technical system.

All those machines that comes under non sap, belongs to the third party.

4.) Web AS ABAP technical systems, ranging from any SAP system to an APO server or CRM server, are based on the same Basis Component (BC), which includes the ABAP interpreter, ABAP Dictionary, ABAP Workbench, and so on. A dedicated database, which stores most of the data of the BC and the application components, is associated with the system.

Hi,

The best way to learn is to go to TCODE SXMB_IFR , then go to SLD and then click on Help, it will show you one PDF and you can read everything about SLD.

The SAP System Landscape Directory (SLD) is a J2EE application. It uses the Common Information Model (CIM) from Distributed Management Task Force, Inc. (http://www.dmtf.org) and implements this vendor’s Web-Based EnterpriseManagement (WBEM) for client-server communications.

The SLD Server is a central data storage point for system landscape information for system management applications. The SLD Server guarantees the consistency of the stored data. Data in the SLD can be split into two categories:

· Component Information

This category includes information about all available SAP software modules (such as products, software components, and Support Packages), as well as information about how you can combine them, and any dependencies on other modules. SAP provides you with the component information; customers can update this information as required at SAP Service Marketplace (http://service.sap.com) (for more information, see SAP Note 669669). Customers can also add components from third-party vendors to their SLD.

· Landscape Description

This category describes the individual system landscape installed at the customer site. The description of the components that are actually installed, combined with the component information, provides reliable and up-to-date data for system management applications. Data Suppliers are provided for R/3 Systems and SAP Web Application Servers. These Data Suppliers are configured specifically for each system and send the current system data to the SLD at regular intervals (for more information, see SAP Notes 584654 and 673144).

SLD Steps for starting a XI project

Configuration Steps

The configuration steps that you need to perform depend on the type of system. The following system types are relevant for the SAP System Landscape Directory (SLD):

· SAP technical systems

The following SAP systems do not need to be configured manually since they automatically register themselves in the SLD:

- SAP Basis systems as of Release 4.0B

- All SAP Web AS ABAP systems

- SAP Web AS Java systems as of Release 6.40

SAP XI has several SLD use cases:

- The SLD acts as a server for application business system names for the receiver

determination in the Integration Directory. Therefore, all business systems must

be available in one master SLD if you need to send messages from a business

system in Region 1 to a receiver system in Region 2.

- The SLD acts as a server for application business system names for application

systems to get their own business system name (Java Proxy Framework and

SAP systems).

- The SLD provides the transport targets for Integration Directory content

transports, such as from a business system in a development environment to a

business system in a test environment.

- The SLD provides all systems and adapters for the end-to-end monitoring in the

Runtime Workbench assigned to an Integration Server.

- The SLD provides the address for the transfer of adapter configuration data from

the Integration Directory to the adapter cache.

- The SLD contains functions for software component version management.

Hi,

<b>refer this thread for answers.. and see my post..

</b>

Technical systems are application systems that are installed in your system landscape (a CRM server, for example). You can manage data about these application systems by using the landscape description of the SLD. Most systems (Web AS ABAP and Web AS Java

systems) automatically report information to the SLD about the elements that they contain by using the SLD data supplier programs. You need to manually register the following types of system only:

• Standalone Java systems

• Third-party systems

To manually register these systems – and if you want to maintain additional data about

automatically registered systems – you use the technical system browser.

Registering Standalone Java Systems

Whereas SAP systems handle business processes by using a highly developed client system,

most applications run as separate systems. These systems are called standalone systems.

Prerequisites

• You have the user role LcrInstanceWriterLD.

• You have navigated to the Technical System Browser.

Procedure

...

1. Choose New Technical System... .

The browser displays the screen Technical System Wizard in a separate window.

2. Select Standalone Java, and then choose Next.

The browser displays the screen for registering an SAP standalone Java system.

3. Enter the technical system identification and the system host name.

The technical system identification is a unique system ID.

The system host name specifies the host where the application runs.

4. Choose Finish.

The SLD server has now registered the standalone Java system.

Web As Java config :

Maintaining Additional Data About Web AS Java Systems

Web AS Java systems that are installed in your system landscape automatically report

information about the elements that they contain by using the SLD data supplier programs.

However, some data is not automatically reported; you have to maintain this data manually.

Examples of this data are the administrative contact (e-mail address) and the JCo

destinations. This procedure explains how to add a JCo destination.

Prerequisites

You have navigated to the Technical System Browser (by choosing Technical Landscape on

the initial screen of the SLD).

Procedure

1. In the drop-down list Technical System Type, select Web AS Java.

The browser displays a list of all the Web AS Java systems that have been registered

in the SLD.

2. Select the system to which you want to add JCo destinations by clicking the system in

the Name column.

The browser displays the detail view of the relevant system.

3. Under JCo Destinations, choose Add.

4. Enter the relevant data in the fields and choose Save.

On the detail screen, you can also enter a description of the Web AS Java system and the name of the system administrator.

hope this will help you in all extend.

Have you ever considered searching for previous replies/ using help.sap.com?

These type of questions are answered a zillion times in SDN and are very basic that you can find the answer yourself if only you really need them.

Hi Keerthi,

You can get the answer in the SLD

there are 6 types...

the types are also pretty self explainatory.

for ex: third party type deals with the systems which are neither SAP not Java systems.
