@nadment: There are 3 ways to setup a connection for oracle in Hop.

If you have a SID, to use this (old) format: jdbc:oracle:thin:@hostname:PORT:SID
Put the SID as is in the database name

If you have a service name, use this (newer) format: jdbc:oracle:thin:@//HOSTNAME:PORT/SERVICENAME
Put the service name with '/' prefix in the database name

If you want to use TNS format: jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=host) (PORT=port)) (CONNECT_DATA=(SERVICE_NAME=service_name))
Put the TNS description in the database name and leave the hostname empty as well as the port.
