Starting and Stopping the SAP Gateway 

Use

Under UNIX and Windows you start and stop the SAP Gateway together with the SAP System. The gateway is started by the dispatcher. No special entries are required in the sapstart script.

For more information see Starting and Stopping SAP Systems and Instances in the System Management documentation.

To find out how to start and stop the SAP Gateway processes of the R/2 Workstation Software on the various platforms, look in the relevant document.

Prerequisites

You have installed the gateway together with your instance, or as a gateway instance (standalone gateway). For more information see the SAP Service Marketplace.

 http://service.sap.com/instguidesNW04 .

under Installation in Inst. Guide SAP Web AS ABAP for your platform.

The gateway instance has its own SID (for example, G11) and instance number, and the executable gwrd(.exe) is located in the corresponding directory (for example, /usr/sap/G11/SYS/exe/run).

Procedure

Standalone Gateway on UNIX

To start a SAP Gateway installed separately on a UNIX machine, you specify a start profile:
gwrd -force pf=<profile> &

To cancel, you must send the INT signal to the gateway read process.

Use the following command to obtain the process ID (PID) of the gateway read process:
ps -ef | grep gwrd

To kill the process, send the relevant INT signal to the process:
kill INT <pid>

Standalone Gateway on Windows

You can start and stop the standalone gateway just the same on Windows. You just have to use sapntkill instead of kill, or exit the process from the task manager.  Usually you use the SAP Service Manager to start an SAP Gateway installed separately on Windows. For more information see the documentation specified above.
