Using PSQL in SAS web infrastructure platform data server

SAS uses postgres DB for shared services as a default choice. The installation file is located under SAS home -> SAS Web Infrastructure Platform Data Server. The psql is located under the bin directory. PSQL is the postgres client software used to connect to postgre database. In simple words it is similar to SQL developer but psql is a command line interface.

psql location in SAS:


Issue:

When running psql we get following error message.

psql: symbol lookup error: psql: undefined symbol: PQconnectdbParams



Solution:

This can be solved by linking a library to usr lib.

Library name - libpq.so.5

Create symbolic link of this library to /usr/lib and /usr/lib64



Connecting using PSQL:

You can use any user to connect to the database. However you need database username and password. In the below screenshot dbmsowner is the username and postgres is the database name. I have hidden the hostname using the hand, usually will be computer server.

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.
