The procedure to configure authentication is as follows:

2. Configure SSL on the server side. Store a certificate in the Wallet at the server side.
3. Configure the network configuration files
listener.ora
andsqlnet.ora
on the server side so it supports SSL4. Configure the client network files,
sqlnet.ora
andtnsnames.ora
so it supports SSL.5. Create a user whose authentication is performed with a certificate.
