Without logs from both sides, it's not easy to say exactly what's going on. The Primary and Secondary should have different, unique names and IP addresses. Oracle and TNS are resolving the names of Oracle services, not necessarily DNS names. Once the Primary's Oracle can identify and connect to the Secondary, the Primary tells the Secondary what data structures to build, and begins trying to sync it's own [Primary's] database to the Secondary.
Trouble can happen all sorts of places in between. Double check the Ports Used listing from the Prime Infrastructure Quick Start Guide to make sure that there aren't any Oracle ports blocked between the Primary and Secondary.
If you haven't already reimaged the Secondary from the .iso image (burned on a dual layer DVD burner to a dual layer DVD disk), that might be a good place to start, just to make sure that if something squirrelly happened to the image onboard the disk hasn't had anything weird happen to it.
Please be aware of a new bug: CSCuj84053 PI Update.4-16 cannot be installed on a secondary
The Primary can/should/must have the Update-4 patch on it, and still be able to sync with a Secondary that only has the Update-1 patch. Might want to go to the Bug Search Tool and sign up for updates on it.
