I just downloaded Oracle SQL developer for my Learning, while trying to log-in for connection, this result keeps showing "Status: Failure - Test failure: IO Error: The Network Adapter could not establish the connection"
What should be the value on the following fields; connection name, username, Password, connection type, role, host name, port, SID etc.
Because I'v used those used in the downloaded tutorial on the oracle side for SQL developer.
Kindly , save me from this problem.
Do you have a database installed already? If yes
host name = give the host name or ip address of the database server
port=1521 is the default try with this if not check in the database
SID = your oracle database sid
