Empty Web App Servers

jklaverstijn — Thu, 18 Sep 2025 08:24:14 GMT

We are in the process of new grid deployments using 9.4M9. We have also decided to discontinue the use of certain web applications like Enterprise Miner (use Viya for that), Business Data Network and Business Rule Manager. I have unchecked these apps in the deployment wizard. The products currently do still exist in our setinit.

Now the apps are not installed but the Web App Servers SASServer7_1 and SASServer11_1 instances are created with empty sas_webapps directories. They are also started and stopped in the sas.servers scripting.

This makes for the fastest startup times of any web app server I have seen in my life but it still bothers me that they are there; I'd like to see them gone altogether.

Now, my question is: can I go scorched earth by removing their directories in the WebAppServer directory? Their presence in that location is triggering the start/stop actions. And remove their mentions in the webserver config? Or is there more and will I mess things up? Like metadata.

Thanks in advance for your input.

Kind regards,
- Jan.

Caveat Emptor, and also make sure you have a backup, but you can add simple conditional logic to start_saswebappsrv() in Lev1/sas.servers.mid so it looks something like the following. Any time you are managing updates/hot fixes etc, you will want to toggle back to the original sas.servers.mid script. This would be a lot safer than the "scorched earth" approach 🙂

start_saswebappsrv() { if [ ! -z "$SASWEBAPPLIST" ] then { for SASWEBAPPINSTANCE in $SASWEBAPPLIST; do if [ "$SASWEBAPPINSTANCE" = "SASServer7_1" ] || [ "$SASWEBAPPINSTANCE" = "SASServer11_1" ]; then echo "Skipping $SASWEBAPPINSTANCE" continue fi start_saswebappsrv_instance; done } fi }
