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
www.magnifictraining.com
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
www.magnifictraining.com
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
