The Network Adapter could not establish the connection when connecting with Oracle DB

Question

When trying to connect with a remote Oracle database via JDBC I receive the following exception:

java.sql.SQLRecoverableException: IO-fout: The Network Adapt         


        

Answer 1

If it is on a Linux box, I would suggest you add the database IP name and IP resolution to the /etc/hosts.

I have the same error and when we do the above, it works fine.
