Hi Andrew, I don't think it is possible to get the information you want from the database since Oracle doesn't know the hostnames for instances that aren't running. With RAC (I'm not talking about Clusterware), there are no database configurations that you would use to describe the list of hosts configured for a particular database. That configuration lies outside the database in the clusterware configuration (hence the OS commands offered in this thread). Put directly: The database doesn't know how many instances there are *supposed* to be nor on which hosts those instances may be started until it actually happens. All the database knows is that it only has X threads of redo, so only X instances can be started, but it doesn't care (or know) where those instances will be started (or if they'll ever be started). So, if you want to find out which hosts are configured to run an instance of the ORCL database, you'll have to query the clusterware via the srvctl or crs_* commands.
