      Hi every one,

       

      Im new in Database and in sql, I recently installed SQL Developer on mac because i couldnt found oracle database express 11g or 12c for mac.

      After installation I install the clients that listed here :

       

      Instant Client downloads for Mac OS X (Intel x86)

       

      And I Followed instructions that toad explained here :

       

      Connecting to Oracle with Toad - Mac Edition (updated for OS X 10.9 Mavericks!) - Toad - Mac Edition - Toad – Mac Editi…

       

      So after all these steps i tested the connection by running this code in terminal

       

      /usr/bin/sqlplus scott/tiger@myoracle

       

      and i Got Error saying: TNS:could not resolve the connect identifier specified

       

      and i tried creating new connection in SQL developer i got this error:

       

      IO Error: The Network Adapter could not establish the connection 

       

      What can i do ?? <

       

      I checked TNSNames.ora and there is no mistake !!

       

      so PLEASE HELP ME, DONT give me previous post link because i check all of them before posting new one

       

      Thanks in advance
