Unable to create new connection

[manch84]

Hello to all,
Am new to oracle sql, and I am using the developer to create new database. Unfortunately, when I try to create new connection and error appears saying that :
Status: failure –lo exception. The network adapter could not establish the connection.

Connection Name: NewDatabase
Username: test
Password: test

HostName: localhost
Port: 1521
SID: xe

Thank you

Is the database created?. Can you logon to the server and see if database instance is up and database is open. If yes, then you need to modify your tnsnames.ora file to include new database connection detail.

no, this is the very first time i run developer!

the error that appears is :Failure -io exception: Got minus one from a read call

any clues?

I am not sure whether you can create a database from Oracle developer, can you create it using SQL Plus?
