It's possible dbca puts the dbname there because everything under
$ORACLE_BASE/admin is stored under the dbname rather than the instance name.
I don't know, it's just a possibility.
All in all there is an inconsistency there when it comes to RAC. Some things
you have to use the instance name for and other things you have to use the
dbname for and Oracle has not updated all scripts to handle this very
elegantly.
Thanks,
