SAP Web AS 6.20 with a 6.20 kernel

The HTTP port for the SAP message server is configured (profile parameter ms/http_port)

Starting the SAP Web Dispatcher

You start the SAP Web dispatcher with the command

sapwebdisp pf=<Profile name> [-f <tracefile> -t <tracelevel> -cleanup -version]

The optional parameters have the following meaning.

You can use -f to determine the name of the trace file. The standard is dev_webdisp.

You can use option -t to set the trace level.

-cleanup means that common resources (shared memory and so on) are released. This is necessary if the SAP Web dispatcher ran was not stopped in an orderly manner the last time it ran, but was terminated by a crash.

-version displays the version of the SAP Web dispatcher. The program is not started.

You usually start the SAP Web dispatcher as follows:

sapwebdisp pf=<Profile name>

If you want to stop the SAP Web dispatcher, you determine the parameter ID and enter the following command: kill -2 <pid> (UNIX) or sapntkill -2 <pid> (Windows NT).
