Looks like you missing some Oracle setup stuff via CONNECT signon. I'm guessing that the $ORACLE_HOME environment variable is not being set when you signon hence SAS can't find the Oracle executables - this only applies if you are using SAS/ACCESS to Oracle.
Try using the SYSEXIST SAS function to check this:
data _null_; if sysexist('$ORACLE_HOME') then do; put "Exists"; Oracle_Home = sysget('$ORACLE_HOME'); put Oracle_Home = ; end; else put "Not exists"; run;
You may need to work with your SAS server administrator on this one.
