I'm an OK dba with MySQL, passable with SQL Server, awful with Oracle.
I have a Windows Server 2008 R2 running Oracle 11g. I'd like to connect to this server with SQL Developer running on Windows XP Mode with a Windows 7 machine on the same LAN. I finally got SQL Developer running but can't connect to the server. I generally connect using TNS names. Is an Oracle client still required on the client machine or does the SQL Developer folder tree have everything I need to connect to the server?
