# SAP Web Dispatcher The Web Dispatcher terminates/forwards HTTP(S) to the SAP back-end (message-server load balancing + SSL). Two deployment shapes: - **Instance-based** (modern S/4): a real SAP instance `W<nr>` with `sapstartsrv` — driven by **SAPControl** exactly like any instance ([sap-system-lifecycle](../sap-system-lifecycle/SKILL.md)). - **Standalone binary**: the `sapwebdisp` executable + a profile, started/stopped directly. > **Guardrail:** it's internet-/user-facing — a stop **drops all active HTTP sessions**. Identify SID/host, > classify PRD, confirm before bouncing. `saprouttab`-style access and SSL config are security-sensitive. --- ## 1. Start / stop / status ### Instance-based (has `sapstartsrv`) ```bash sapcontrol -nr <nr> -function Start # start; Stop / RestartSystem to stop / restart sapcontrol -nr <nr> -function GetProcessList # status — the WEBDISP/ICMAN process GREEN ``` ### Standalone binary ```bash # start (UNIX/Windows) — profile holds ports + backend systems: sapwebdisp pf=<path>/sapwebdisp.pfl # Windows: sapwebdisp.exe pf=… [G, W1] # stop — send SIGINT to the PID: kill -2 <pid> # UNIX (graceful) [G, W1] sapntkill -INT <pid> # Windows [G, W1] # or, if installed as a Windows service: Services.msc → stop "sapwebdisp" ``` Useful start options [G, W1]: `-f <tracefile>`, `-t <tracelevel>`, `-cleanup` (release shared memory), `-auto_re
