I installed Oracle 11g Enterprise Edition on my Windows 7 Pro. My problem is that I cannot log into database from other host (local network).
When I connect to database using Oracle SQLdeveloper everything is ok as long as I specify 'localhost' in connection configuration. However, when I change it to '192.168.0.190' which is my host IP address I get 'The Network Adapter could not establish the connection'. I get the same error when logging in from other host in local network.
What is the problem?
