Cause
Incorrect naming convention for fal_client parameter
Primary shipped particular log seq# to a destination pointed by log_archive_dest_2=p1ncm2_<host>
The standby can do its own GAP analysis and can request logs from the FAL_SERVERS.

The FAL servers, in this case the primary, will try to honor that request.
when standby attempts to resolve a gap, primary gets a different fal_client=p1ncm1_<host>

In effect p1ncm2_<host> and p1ncm1_<host> point the same standby

If we set up fal_client on standby with a different tns alias that we have set at primary's LADn,
then ORA-16401 is expected.

If the TNS alias had matched, then we would have been able to see that the FAL request from the standby was the same as the FAL request created by regular LADn redo shipping,
and we would not have created the second FRB (FAL Request Block)

Consequently no ORA-16401 would have been reported

In 11gR2 we explicitly say that FAL_CLIENT is optional and should not be used. In which case we use the DB_UNIQUE_NAME of the sender of the request to match up to a LADn. So there would not have been redundant request for the same log seq#.
Solution

Make sure primary's log_archive_dest_n remote desitnation and standby's fal_client share
the same tns alias.


---primary --

log_archive_dest_2             service=p1ncm2_<host> optional reopen=60 valid_for=(ONLINE_LOGFILES,PRIMARY_ROLE) db_unique_name=p1ncm2
alter system set fal_client=p1ncm1_<host> scope=both sid='*';

--- standby ---

Current Parameter Value:-

fal_client                     p1ncm2_<host>

Proposed Parameter Value:-

alter system set fal_client=p1ncm2_<host> scope=both sid='*'; ## same as primary's LAD_2
