The Software-Oriented View of R/3
4
The SAP R/3 System Architecture

• Implications for Application Programming
• Separate presentation and application layers
  implies that when you run an application program
  that requires user interaction, control of the
  program is continually passed backwards and
  forwards between layers.
• When a screen is ready for user input, the
  presentation layer is active, and the application
  server is inactive with regard to that particular
  program.
• As a consequence, the program logic in an
  application program that occurs between two
  screens is known as a DIALOG STEP.

The SAP R/3 System Architecture

• Application Layer (cont.)
• Application Server
• R/3 programs run on application servers
• The APPLICATION SERVER communicate with the
  presentation components, the database, and also
  with each other, using a MESSAGE SERVER.
• Main components
• Work Processes (Dialog, Update, Enqueue, Batch,
  Spool)
• Dispatcher
• Gateway
• Message Server

Dispatcher

• Program which manages resources of the R/3
  applications
• Receives requests from user and passes them to
  the corresponding work processes
• Only one dispatcher per application server

www.magnifictraining.com
10
Dispatcher Tasks

• Balances the workload between the processes
• Buffer management in main memory
• Connection with the presentation level
• Organization of the communication processes

Work Process

• Responsible for executing R/3 application tasks

Dialog Work Processes

• Responsible for the interactive tasks of the R/3
  system
• Dialog work processes execute only one dialog
  step at a time and are immediately freed for the
  next user request
• Constantly switching between users

Dialog
14
Background Work Processes

• Responsible for executing ABAP programs submitted
  for background execution
• Batch jobs schedule the sequence of program
  execution
• Used for running long and time consuming programs

Batch
B
15
Spool Work Processes

• Responsible for formatting the data for printing
  and passing it to the host spool system
• Only one spool work process allowed per server

Spool

16
Enqueue Work Processes

• Responsible for the lock management system
• Synchronizes database access for the multiple
  application servers and work processes
• Only one enqueue process per R/3 system to ensure
  data integrity

Enqueue
E

17
Update Work Processes

• Responsible for making database changes requested
  by dialog and background processes
• For better performance, this process should be on
  the database server

Update
V

18
V1 vs. V2 Update Processes

• Time-critical processes are inside V1 and less
  critical ones within V2
• Error situations in
• V1 changes rolled back and V2 components not
  executed
• V2 only changes of V2 components rolled back

Update
V

19
Message Server

• Used by different application servers to exchange
  data and internal messages
• Routes messages, such as update or batch job
  starts, between application servers
• One message server per system

Message
M

Gateway Server

• Allows communication between R/3, R/2, and
  external applications
• Exchanges large amounts of information between
  application servers
• Gateway can reside on any of the connected systems

Work Processes

• Number of work processes can only be changed
  after restarting the system
• Should have at least two dialog work processes
• Need to have at least one V1 and V2 processes
• Number of spool processes cannot be changed
