ERROR: Unable to establish a SAS Metadata Server connection. Proc Upload

vfarmak — Fri, 27 Feb 2026 08:11:37 GMT

Hi everone!

I execute a proc upload statement as listed below:


%let sashost=sasva01.myserver.com 7551;
options COMAMID=tcp;
libname vaload 'E:\SAS\VA';
signon sashost user='lasradm' password='mypassword';
rsubmit status=no;
libname SASDATA BASE "/opt/sas/sashome/DATA";
proc upload inlib=WORK outlib=SASDATA memtype=data;
select my_dataset;
run;
endrsubmit;
signoff;

And I Get the following error:

You are running SAS 9. Some SAS 8 files will be automatically converted
by the V9 engine; others are incompatible. Please see
http://support.sas.com/rnd/migration/planning/platform/64bit.html

PROC MIGRATE will preserve current SAS file attributes and is
recommended for converting all your SAS libraries from any
SAS 8 release to SAS 9. For details and examples, please see

ERROR: Unable to establish a SAS Metadata Server connection.

The Visual Analytics machine is a linux server, whereas the machine in which the SAS Data Integration Studio is installed is a Windows machine.

Any ideas?

Best Regards

We have a slightly different setup, SAS Compute (corresponds to your DI Server I assume) is on the same host as LASR root (controller) node.

How is your LASR defined in metadata, when it comes to Logical Server, hosts etc?

Also, it doesn't look like you are using the SAS LASR Analytic Server Loader transformation?

Please share your Job diagram and the complete job code.

/** Step end Proc Upload **/

I have also compressed the file including the image.

The SAS LASR Analytic Server Loader transformation I think that we do not have it (at least from the list option access options available in SAS Data Integration Studio.
