what program do you try to connect with?
Is the database a local or remote database?

please post the connect string (annonymize it)

A lot of things to check. See if you have listener running on your database. Try to use the tnsping to see if there's connection.

And of course let us know what tool are you using to connect: SQLPlus, OEM?
