Aqua Studio
If you are having problems connecting to a Oracle Instance using Aqua Data Studio that has a similar tag:
jdbc:oracle:thin:@//58.37.64.169:1521/MyDBOn a Macintosh you are best to use SQLGrinder. I have found that Aqua Studio doesn't handle service name varient too well.
The Oracle thin driver supports two variants of the database specifier: the service name and sid variants. Oracle highly recommends using the service name version of the connection URL. In fact they no longer describe the sid version in their current documentation. We describe both because some users may be more comfortable with the traditional sid over the new service name.
