      Hi,

       

      I am a beginner, I installed oracle 11g R2. I also created a database.

       

      Unfortunately, I am not able to create a connection to databse in SQL Developer.

       

      It is giving me error : the network adapter could not establish connection

       

      I appreciate your help
