Hi,
Can you look at RMAN configuration for db_unique_name configuration? If the
primary and standby are configured with a connect string ( Oracle Net
tnsnames aliases specified) you should not have this problem.
Look at
http://docs.oracle.com/cd/B28359_01/backup.111/b28273/rcmsynta010.htm
for the configure db_unique_name <name> connect identifier synatax.
Best Regards,
Guenadi Jilevski
