Can't create a connection


I am trying to use QUest SQL Optimizer for Oracle 9.3.4. Everytime I try to create a connection it gives me a TNS error. I am copy-pasting the information directly from Toad for Oracle where it works just fine.

To reproduce:

  1. Run SQL Optimizer from Windows 10 menu.
  2. Click CONNECTION button on upper right of screen
  3. Copy-paste direct connection info from toad.
  4. Click create connection.
  5. Get tns error.

I have tried this with 3 different DB connections that work from Toad by not from SQL Optimizier.

Any idea what I am doing wrong?
