SAS Enterprise miner SSL error in SAS 9.4

Issue:

I see below error message in SAS Enterprise Miner log:

ERROR: SSL Error: Missing CA trust list

Solution:

This issue occurs if SSL certificate is not set correctly. To rectify this problem, you need to mention the SSL certificate location in SSLCALISTLOC option. SSLCALISTLOC option can be invoked in many ways. Here I will explain invoking this option using Workspace Server. 

1. Stop the Object spawner.
2. Take backup of  /sas-config-directory/Lev1/SASApp/WorkspaceServer/sasv9_usermods.cfg and opne the file in your favorite text editor. 
3. Add the below line to the file
4. SSLCALISTLOC="/etc/pki/tls/cert.pem"
5. Save the file.
6. Start the Object spawner. 

Run below code in SAS Enterprise Guide to check the settings change:
proc options option=SSLCALISTLOC value; run;
