how many work process r there in application server...

The various work processes are described briefly below. Other parts of this documentation describe the individual components of the application server and the R/3 System in more detail.

<b>

Dialog Work Process</b>

Dialog work processes deal with requests from an active user to execute dialog steps.

<b>Update Work Process</b>

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.

<b>Background Work Process</b>

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

<b>Enqueue Work Process</b>

The enqueue work process administers a lock table in the shared memory area. The lock table contains the logical database locks for the R/3 System and is an important part of the SAP LUW concept. In an R/3 System, you may only have one lock table. You may therefore also only have one application server with enqueue work processes.

<b>Spool Work Process</b>

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

The services offered by an application server are determined by the types of its work processes. One application server may, of course, have more than one function. For example, it may be both a dialog server and the enqueue server, if it has several dialog work processes and an enqueue work process.

You can use the system administration functions to switch a work process between dialog and background modes while the system is still running. This allows you, for example, to switch an R/3 System between day and night operation, where you have more dialog than background work processes during the day, and the other way around during the night.

The types of WPs are - Dialog Work Process, Update Work Process, Background Work Process, Enqueue Work Process, Spool Work Process.

If you want to know the number of them on the App server, goto transaction code SM50. This lists the WPs.
