Is it possible to connect to a RAC with a JDBC driver using a "global" SID rather than a service nam

We are migrating our application to RAC and we provided a service name and connection string example.

It turns out, the application will require code change to fit the new connection string and tight schedule means the developers would prefer to continue using a "SID".

I explained that using a SID meant connecting to only one node and loss of load balancing and high availability.
However someone in the room mentioned something I never heard before, that it was possible to use a global sid.

Of course I tried it and (using dbname as sid) and it didn't work but it was mentioned that it may need to be configured.
