Home -> Community -> Usenet -> c.d.o.tools -> Re: new question about the set-up
The host string is looking for a subsection in your TNSNAMES.ORA file. The file is used by the client to create Oracle's Protocol stack. There should be SQLNet easy config utility on your machine to set this up. Also checkdocumentation for TNSNAMES or LISTENER.
Good luck :)
