Does anyone know what this error message means:
ORA-03121 No interface drivers connected - function not performed
It appears when trying to logon to SQL Plus 3.3.
I am installing Oracle software onto a NT4 desktop. I have installed Discoverer 3.1, Enterprise Manager 1.5.0, Oracle Developer 2000 & the Oracle 8 client(v 18.104.22.168.0).
I installed SQL Plus 3.3 from Oracle Discoverer 3.0 & have since installed all of Discoverer 3.0 but this hasn't helped.
