Hi PAVB
I understand what you're saying. But Oracle won't let me connect even as sysdba, in the first place. I tried relink all; attached is its output. (I had to break them down to 2, as they exceeded 100K size limit.) And after relinking, 'env | grep ORA' gives me correct paths. But still I am getting following error.
[oracle@oradb1 ~]$ sqlplus /nolog
