SAS viya session error

sathya66 — Wed, 30 Sep 2020 15:03:37 GMT

All,

I am running this code from SAS EG to upload one table to caslib=casuser

It was working fine before.

this is happening only after installing new hotfixes on our machines. do we need to look for any files to get it work.

I found this is very usefull but we are on Linux and also user name is 8 characters or less and the password is 15 characters or less

https://support.sas.com/kb/66/487.html

sas94 and viya are on diffrent servers.

options cashost="test.com" casport=5570; 
cas mysession sessopts=(caslib=casuser timeout=1800 ); 
cas;                   /* log on to the CAS session */
   caslib _all_ assign;   /* create a libref for each active 
                             caslib */

options cashost="test.com" casport=5570;
29 cas mysession sessopts=(caslib=casuser timeout=1800 );

And Just checked cas services are UP and running but cas-shared-default server status (port:-5570) is not in green in environment manager.
And SAS studioV is also not working.

Welcome to SAS® Studio

@ehsanullah the issue you are facing is a kerberos handshake issue. I would suggest working through the troubleshooting steps found in this blog: https://communities.sas.com/t5/SAS-Communities-Library/SAS-Viya-3-5-Kerberos-Troubleshooting/ta-p/636283 After that, if you still cannot find the issue, I would suggest opening up a SAS Technical Support ticket for assistance going through your kerberos configuration to see where the issue is coming from.
