Error Create CAS Connection

DavidLie — Thu, 30 Jul 2020 12:37:41 GMT

Hi SAS Studio Expert,

This is the first time that I'm using (and accessing) the SAS Studio. I guess the first part is to create a CAS connection and I'm having trouble with that. The error message that I'm getting is:

ERROR: The host name 'sas1' could not be found.

ERROR: Unable to connect to Cloud Analytic Services sas1 on port 5570. Verify connection parameters and retry.

When I hover around the community, I notice that I need to connect something to somewhere. If you can teach me some of the steps, that would be awesome.

Thanks.

Best,
David

Are you sure sas1 is a valid fully qualified domain name (FQDN) of the CAS server?

Also, if you are connecting to the CAS server from SAS Studio V, you do not have to specify the hostname.

Hi alexal,

Thank you for replying. I'm unsure - just following some tutorials. How do we check the FQDN? Are there any guidelines that I can follow? Your help is greatly appreciated.

Open the SAS Environment Manager http://<SAS_VIYA_HOSTNAME>/SASEnvironmentManager/ and go to the "Servers" menu on the left-hand side. Then on the right-hand side, you will see the actual hostname of your CAS server. Again, if you are connecting from the SAS Studio V, then you do not have to specify the name of the server.
