Question

Java. Sql. Sqlrecoverableexception: IO Error: The network adapter could not establish the connection..

Do I need to specify the VPN details in databricks?

Answer 1

Even if you connected to VPN, the Databricks cluster that is running in the cloud couldn't reach your on-premise Oracle installation. To achieve that you need to work with your networking team on setting VPN connection between on-premise & cloud. It's described in the documentation in great details, so it doesn't make sense to repeat it here.

Answer 2

Hostnames which are being used in the Databricks clusters should be enabled to access on-prem resources through Endpoint Services.You can ref: link
