Hi Sudheer,

If you are refering to the downloads:

- Linux/Unix are "servers" only = all components other than clients.

- Windows has "Server" downloads which are Server and Client in one installation package

and then there Client only (obvioulsy only for Windows..Designer = Windows)

Client only =  the (Windows) Designer that is needed to define the datasources and create the job. You drag and drop elements on the main window (although it is a little more complicated )

You can put a Designer on every Laptop of your Data Flow developers, but they will be pointing back to the Server to execute the jobs. (So even if you create the job in the Designer and rightclick to execute it, the Designer will simply save the job into the shared database (called repository) and tell the Server to execute that job.)

Once this design part  done the job will be saved in the (repository) database and can be executed by the JobServer.

Somehow inbetween is the Management console which is a web interface on tomcat. For the installation it is still "Server" part. It will show you if Jobs have completed and you can start jobs from there. However the jobs must exist and you can't create them.

Hi Sudheer ,

I am not sure I understand fully what you mean by  differences between server and client components, but here what I think I understandand I am  also assuming that  you are referring to DS 3.x version.

When you install Data Services,  you have a choice of selection between server and client components.  These  components may have different requirements basedon the given supported platforms. For example you can install DS client designer on Vista OS whereas you can't for the job server. Likewise you can install server components on a Unix platform but not DS client tools. Alternatively on a supported Windows server you can install everything if needed.

So basically you need to verify the supported platform document OS ( http://service.sap.com/bosap-support ) look for Desktop and Server products.

Furthermore, here is what you get when you install DS with explanation of what each component does:

Server components:

• Access server: Provide realtime access to DS.
• Job Server: Executes batch DS jobs
• Technology Interface: Provides access to technologies such JMS and Salesforce.com
• Metadata Integrator: Collects metadata from BOE system for impact and analysis

Client:

• Designer
• Repository:Creates and manages all types of DS repositories(Local,Central,profiler)

Web-tier:

• Management Console: Web application that manages DS environment

Message client components :

• Client SDK

Documentation.

Hope this helps.

Which components ?

The main client component is the designer where you develop jobs.

The main server component is the job server, which runs jobs.

But there are many other client and server components.

It might help to understand why you are asking ?

Hi Leigh Kennedy,

I know about the components access server and job server will belongs to server componets.

But am asking the Difference between them and where they will reside in Data services.

Thanks for Replay...

Hi Leigh,

Designer is the component where you can actually develop the ETL jobs.

Repository have two types - Local & Central repository where Local repository is the space where you will design the jobs which will be stored in the database . Central repository can only store the jobs ( versions of job are maintained when chnaegs are done to the job).

Job server enables to run the batch jobs

Access server enables to run the real time jobs .

thanks,
