disp+work, Dispatcher, GRAY, Stopped

I installed SAP Netweaver on Linux Mint and was getting the issue of dispatcher not starting.

GetProcessList

name, description, dispstatus, textstatus, starttime, elapsedtime, pid
disp+work, Dispatcher, GRAY, Stopped, , , 7230

The issue is that with a local system on a laptop, it uses the loop-back address.

So you have to set the following in your profile file:

/usr/sap/NPL/SYS/profile/NPL_D00_vhcalnplci

Add the following line:

rdisp/tolerate_loopback_addr=yes

Make the change and restart your laptop/system.

The output is now as shown below:

vhcalnplci:npladm 2> sapcontrol -nr 00 -function GetProcessList
