ORA-12504: TNS: listener was not given...

FC60Sep 11 2018 — edited Sep 14 2018

Hi,

I use each day SQL Developer without problem. Today, I want to create a ODBC connection and I have installed Oracle Client, but I'm not able to create a connection because I have this error ORA-12504: TNS: listener was not given...

Why?

Thanks for the help
