Presentation Server

The Presentation Server

GUI only

The presentation server is actually a program named sapgui.exe

It is usually installed on a user's workstation

Sends requests to application server Obtains screens from application server and displays


13/1813

Application Server

Application Servers- A set of executables that collectively manage the input and the

output for ABAP/4 Programs.

- If ABAP/4 program requests information from the database, the

application server will format the request and send it to the

database server.

An application sever profile specifies:

- Number of processes and their types

- Amount of memory each process may use

- Length of time a user is inactive before being automatically

logged off


14/1814

Database Server

The Database Server

Interface between application server and RDBMS

The database server is a set of executables that accept database

requests from the application server

Also holds the vendor specific DB driver

R/3 ArchitectureWork Processes.

Dialog Work process Background work Process

The Dialog work process fulfill all requests

for the execution of dialog steps triggered

by an active user.

The background work processes execute

programs that run without user interaction.

They are not used for a request which

take long time and which use more cpu.

Every dispatcher requires at least two

dialog work processes

At least two background work processes

are required per SAP system

If the dialog work process does not

respond in this time, it will be terminated.

Also dialog work process are multiplexed to

handle large no of user request

Usually the background work process are

used for carrying jobs that take long time to

finish, like client copy, client transport etc..,

There are two types of background work

process type A and type B. A type

background work process are used for

mission critical jobs.

R/3 landscape

In an SAP R/3 scenario there will be multiple servers present.

Typically these will be: Development, Quality and Production.

All the development and configuration is first done in Dev.

After a round of unit testing the development and configuration

is movedto the next system (Quality)

In quality integration/

regression testing is done.

Finally everything is moved to

production or the actual system

which the client uses i.e Go Live.

History of ABAP

ABAP (Advanced Business Application Programming, is a high levelprogramming language created by the German software company SAP. It is currently

positioned, alongside the more recently introduced Java, as the language for

programming SAPs Web Application Server, part of its Net Weaver platform for building

business applications. Its syntax is somewhat similar to COBOL.

ABAP is one of the many application-specific fourth-generation languages(4GLs) first developed in the 1980s. It was originally the report language for SAP R/2, a

platform that enabled large corporations to build mainframe business applications for

materials management and financial and management accounting

ABAP was one of the first languages to include the concept of Logical Databases

(LDBs), which provides a high level of abstraction from the basic database level.
