Not sure what I am doing wrong because DEFAULT StaticConnectIdentifier does not seem to work.
Google and MOS were not much help.
Using StaticConnectIdentifier as created by dmgrl would fail with the following error during switchover.
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
The error can be found in the listener.log
When using tnsnames for StaticConnectIdentifier, switchover works like a charm.
I keep thinking, there must be something wrong with my configuration but as you can see from the test case, the only changes were to StaticConnectIdentifier.
Both databases are on the same host with each listening on different ports.
Updated: Just found this note
DGMGRL>switchover to Fails with ORA-12514 (Doc ID 1582927.1)
Oracle Database – Enterprise Edition – Version 12.1.0.1 to 12.1.0.1 [Release 12.1]
Interesting to see if this will work.

Thanks to Shivananda Rao (http://shivanandarao-oracle.com/) for pointing out the obvious which I was blind to.
IT’S NOT GLOBAL_NAME = hawklas_DGMGRL !!!
It’s GLOBAL_DBNAME = hawklas_DGMGRL (Missing DB)
R.I.P.
