The recommended practice is to use SIDs because that's what Iwov understands by default. If you must use service names, make sure to use the Oracle thin driver and use a manual JDBC connection string that looks a bit different. Not sure if the installer will allow you to specify what you need, so you might need to use a 'dummy' database for the install and then search+replace all the jdbc mappings everywhere later and recreate the schmas (hence why you'd be better off with SIDs).Standard jdbc connection string:jdbcracle:thin:@myserverort:sidService Name connection string:jdbcracle:thin:@//myserverort/ABCD
