TNS Entry Environment Variable for SAS

After you install Oracle driver in your SAS environment make sure you define following environment variables:

tnsnames.ora file:

This file will be placed in the Oracle installation location under network -> admin. This is where you need to define the connection string. 

 /oracle/product/11.2.0/client_1/network/admin

Oracle.env file:

Inside the file you need to define all your environment variables. Without this your connection is likely to fail. Oracle.env file will be in following location.

 oracle/product/11.2.0/client_1/oracle.env

Environment variables:

All environment variables should be mentioned inside the oracle.env file. Below are the environment variable you need to define:

 ORACLE_BASE=/oracle
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/client_1
TNS_ADMIN=$ORACLE_HOME/network/admin
PATH=$PATH:$ORACLE_HOME/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib   

To test an Oracle connectivity from SAS, you can use below libname statement:

LIBNAME test ORACLE user="Oracle_user" password="urscerslc323" path="production" schema="usrusdrl";

Insufficient authorization to access PIPE error in SAS EG

Issue: When I tried to run SAS code in SAS Enterprise Guide it throws following errors: ERROR: Insufficient authorization to access PIPE. ERROR: Error in the FILENAME statement. Screenshot of error: Solution: This error occurs when you try to run OS commands in SAS code. To run the OS commands in SAS code you need to enable XCMD option. You check it in SAS Management Console by following below steps.   Open SMC -> Expand Servers -> Expand   In SASApp , expand Logical Workspace Server -> right click on Workspace Server. Click properties -> option tab -> advanced options -> launch properties. Check whether Allow XCMD is checked. The issue arises if the Allow XCMD is not checked. In above image, Allow XCMD option is not checked. It should be checked to run OS commands from SAS code.

The authentication server is not SETUID ROOT error in SAS

Question: When validating the SAS Server from SAS Management Console, I received the following error: The authentication server is not SETUID ROOT.  So, I ran the setuid.sh utility and restarted the services many times. I just checked the elssrv sasauth sasperm setuid bit. There were no error in sasauth-debug.log, sasauth-access.log, sasauth-error.log.  Any suggestions? Answer: Please do the following:    1) Run /<SASConfig>/Lev<X>/ObjectSpawner/ObjectSpawner.sh stop  2) Edit /<SASConfig>/Lev<X>/ObjectSpawner/ObjectSpawner.sh and add the code shown below right after SCRIPT=`basename $0`:  if [ -n ""$TKPATH"" ]; then  unset TKPATH  fi   if [ -n ""$TK_PATHLIST"" ]; then  unset TK_PATHLIST  fi    3) Run /<SASConfig>/Lev<X>/ObjectSpawner/ObjectSpawner.sh start  The above code change in ObjectSpawner.sh should fix the issue.
