Based on SAP Note 1836150, I know there is a special
configuration that has to be done in order to get QaaWS to work correctly when
multiple web servers are accessed through a single load balancer. However, my client
has two load balancers for 4 web servers in Production (two load balancers and
3 web servers in Test) – 2 internal web servers on one load balancer and 2 external
web servers on another load balancer. They have never been
configured correctly to work with QaaWS, but have requested that I do this
configuration as part of their upgrade from 4.0 SP5 to 4.1 SP2.
I have the internal web servers in their Test environment
configured, but I’m not sure what needs to be done to configure this for the
external web server(s). I assume that some rules need to be added to the
firewall, but I’m not sure what the specifics are.
Has anyone done this sort of configuration before?
