Hi Gianni Ceresa,
Using below link I'm trying to configure DB Authentication.
Message icon - Error Connection test failed.
Message icon - Error IO Error: The Network Adapter could not establish the connection
I've checked port opening both Ip's between client and server.Its working fine and I've test the connection through SQL developer, there also working fine and connected.
Please guide me where issue will happen and is their any way to analyze log files to debug this issue.
