hi,

Dialog Work Process

Dialog work processes deal with requests from an active user to execute dialog steps (see also Dialog Programming).

Update Work Process

Update work processes execute database update requests. Update requests are part of an SAP LUW that bundle the database operations resulting from the dialog in a database LUW for processing in the background.

Background Work Process

Background work processes process programs that can be executed without user interaction (background jobs).

Enqueue Work Process

The enqueue work process administers a lock table in the shared memory area. The lock table contains the logical database locks for NetWeaver AS ABAP and is an important part of the SAP LUW concept. In NW AS, you may only have one lock table. You may therefore also only have one ABAP application server with enqueue work processes. Normally, a single enqueue work process is sufficient to perform the required tasks.

Spool Work Process

The spool work process passes sequential datasets to a printer or to optical archiving. Each ABAP application server may contain only one spool work process.

hi

good

Work processes execute the individual dialog steps of ABAP application programs. They are components of ABAP application servers. The next two sections describe firstly the structure of a work process, and secondly the different types of work process in NetWeaver AS ABAP.

Hi,

Work Process

Definition

An SAP application server has to process SAP requests from multiple front ends. The application server has the use of a dispatcher, which gathers the requests and transfers them for processing to the work processes. The work processes then execute the desired requests (for example, an ABAP program).

Use

Here are the following types of work processes:

Work Process Type

Use

Dialog

Executes dialog programs (ABAP)

Update

Asynchronous database changes (is controlled by a COMMIT WORK statement in a dialog work process)

Background

Executes time-dependent or event-controlled background jobs

Enqueue

Executes locking operations (if SAP transactions have to synchronize themselves)

Spool

Print formatting (to printer, file or database)

Several dialog work processes usually run on one application server. There are usually only one or two other types of work processes. For more information, see Setting Up Work Process Distribution in the CCMS Documentation.

Structure

A work process consists of a screen processor, the ABAP interpreter, the database interface and the task handler that calls these programs.

Integration

The dispatcher is the central process of the application server. After it has been started, it generates the work process. You can configure the number of different types of work processes that run on an application server (see Setting Up Work Process Distribution).
