server.crt and server.key in that directory. Those files should be stored in PEM format. If those files do not exist, the database uses the same ocient.crt and ocient.key that are used for the internal cluster authentication. The server.crt and server.key files should be used to provide user-defined certificates to the database.
When these files are in place, restart the services, and they automatically make use of TLS and the specified certificate.
By default, the database allows both encrypted and unencrypted database (JDBC) connections, even if the specified server.crt and server.key files exist.
