Yes, DB Connect 2.2.0 works for following two scenario: Scenario1: If you are using Oracle Single Scan(Single Client Access Name), then you should set your connection as set your Host to host-scan-1.com Choose database type to Oracle Service (using ojdbc6.jar) Set default database to my-oracle.com, actually this is your service name Port is 1521 Then you can connect to the host-scan-1.com Scenarios2: If you are using multiple SCAN, san host-scan-1.com and host-scan2.com. You need to specify the URL by your self in JDBC URL Format, see below screenshot. For example: jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = host-scan-1) (PORT = 1521)) (ADDRESS = (PROTOCOL = TCP) (HOST = host-scan-2) (PORT = 1521)) (ADDRESS = (PROTOCOL = TCP) (HOST = host-scan-3) (PORT = 1521)) (CONNECT_DATA = (SERVICE_NAME = myoracle.servicename) (CONNECT_TIMEOUT=5)(RETRY_COUNT=2) ) ) Hope this would help ...
