Hi, I am new to Oracle database and installed Oracle Virtual Box MAnager. I got it running and then installed SQL developer. However, when I try to create a new connection using the following details from my online course:
username: hr
password: oracle
hostname: localhost
port:1521
service name: freepdb1
I receive the following message:
ORA -17002: Connection reset or established connection was aborted by software in your host machine.
I downloaded SQL developer version with Java.
I tried uninstall everything and reinstalled, but I still cannot establish a connection. I tried to adjust some firewall and security setting, but the issue persist.
Could someone please help me resolve this?
Big thank you
