Scheduling upload to CAS task in SAS Viya from .sas code

[madhuramalkar]

Hi All,

We have just migrated from SAS 9.4 environment to SAS Viya environment. Both the environments are running on Linux servers.

In SAS 9.4 we had created SAS EG projects for data preparation and upload to LASR task was also included in same. These projects were scheduled for daily pulls. After migrating to SAS Viya we are able to run all the codes in SASStudio environment and also in SPRE.

I have 2 questions here:

1. I tried putting upload to CAS snippet in the .sas code and tried running from SPRE but that fails with following error:

code : cas mySession2 sessopts=(caslib=casuser timeout=1800 locale="en_US");
ERROR: The request to start or connect to a session failed. Specify a UUID to connect to an existing session or specify a session
name, port and host name to start a session.

How to connect to CAS server from SPRE?

2. Is there any other way to schedule .sas program to run automatically other than running it in SPRE and scheduling it in crontab?

Hi, any luck?

To do this, I've created the .authinfo at the home of the user "sas" (eg).

Now on the code.sas add the cas session:

cas batchsess authinfo="/home/sas/.authinfo" host="cascontroler.fqdn.com" port=5570 sessopts=(caslib=casuser);

Remember, user sas is on the Linux servers and on the LDAP, then you can try this on the SASStudio first

call it with user sas:

/opt/sas/spre/home/SASFoundation/sas code.sas

OR using the batchserver (do this)

/opt/sas/viya/config/etc/batchserver/default/batchserver.sh

Using the batchserver you don't need to set the cas host and port, also you can configure the autoexec, sasv9, sasenv_, etc on the batchserver folder

The .authinfo contains the following (https://documentation.sas.com/api/docsets/authinfo/9.4/content/authinfo.pdf?locale=en😞

default user sas password {sas004}xxxxxx
