How to update or patch the SAP Web Dispatcher?
- Connect to the machine on OS level, where SAP Web Dispatcher is installed. In this case I describe procedure for Linux, but it can be used for other OS’s as a general guide.
- Check current version – below the version is 753:
su – <sid>adm
sapwebdisp -v
>

- Download latest SAP Web Dispatcher SAR archive for version 753 from SAP portal: https://me.sap.com/softwarecentersearch/SAP%20Web%20Dispatcher
- On download page select desired version (753) and desired operating system (Linux in this case)
- Upload the SAP archive to the machine into a desired temporary location, and unpack it:
mkdir /tmp/wdisp-patch
./sapcar.exe -xvf /tmp/wdisp-patch/SAPWEBDISP_SP_1230-80002353.SAR
- Make a backup copy of the current SAP Web Disp directory (to be safe). Backup directory used in example below is: /sapmnt/<SID>/exe/uc/linuxx86_64_backup
cp -R /sapmnt/<SID>/exe/uc/linuxx86_64 /sapmnt/<SID>/exe/uc/linuxx86_64_backup
- Stop SAP Web Dispatcher, execute bellow commands:
sapcontrol -nr <instance_number> -function Stop
cleanipc <instance_number> remove
- Copy unpacked files from temporary directory to /sapmnt/<SID>/exe/uc/linuxx86_64
cd /tmp/wdisp-patch/
cp -R * /sapmnt/<SID>/exe/uc/linuxx86_64
- Start SAP Web Dispatcher after patching
sapcontrol -nr <instance_number> -function RestartService
sapcontrol -nr <instance_number> -function Start
- Your SAP Web Dispatcher is patched with success!
- Check if the process runs. It needs to be in status GREEN. Use this command:
sapcontrol -nr <instance_number> -function GetProcessList
GetProcessList
OK
