This is my first time connecting to an Oracle server. I'm using SQL Developer. They only gave me an IP, the default port (1521), a user name and a password. So I filled them in in the "New / Select Database Connection" dialog. When pressing "Test", I wait for a while, then I get the following:
Status: Failure -Test failed: IO Error: The Network Adapter could not establish the connection
It's possible I don't know what information to ask more from them or they are sending me incomplete information. The first time I asked they only sent me credentials, and when I asked for their server's host, they provided me with a LAN IP (192.168...) when they should know I'm not accessing it from inside their network.
They also sent a "Database name" which I then tried filling in as well (in the "Service name" field, then as the SID, thinking that might be the missing piece, but I always get the same error.
EDIT: I asked them to allow public access from my IP through their firewall, but maybe they didn't understand what I asked, or I'm doing something wrong.
How should I request access from them so that they send me something I can use to connect to their Oracle server? Or how can I troubleshoot / verify access?
