title: How to find Oracle database connection details
body: <p>I am new to Oracle DB and have created a new Oracle 12c database. I am creating a new connection through SQLDeveloper and where can I get the connection details? HostName? Port? SID?</p>
  
  <p>I tried connecting using default details given in documentation but got the below error</p>
  
  <blockquote>
    <p>Test failed: Listener refused the connection with the following error:
    ORA-12505, TNS:listener does not currently know of SID given in connect descriptor></p>
