Getting db_unique_name error on standby...

Question

HP-UX vscdsh01 B.11.23 U ia64
10.2.0 oracle
I have a primary/standby set up that just "stopped" receiving the archive files for some reason. There was no error in the alert log, so I received no notification.
I had to rebuild everything due to archive log retention issues....the configuration was calling for an archive log much older than what was available.
I did a new hot backup, created the new standby control file...transferred everything, brought it back on line doing recover standby database and alter database mount standby database...
everything worked fine.
I then issued an alter system switch logfile on the primary, while watching the alert logs...it showed the switch, but I don't see any activity for sending the log file from the primary to the secondary...
I then issue show parameter on both systems to see what is showing as the destinations. Looks fine.
So I decide to restart the process.
On the primary, I issued the following command...
alter system set log_archive_dest_state_2 = DEFER' --to shut off the shipping of log files.
it came back as system altered.
Then I issued the following, resulting in error...
SQL> alter system set log_archive_dest_2 = "MANDATORY service=SWESC reopen=30";
alter system set log_archive_dest_2 = "MANDATORY service=SWESC reopen=30"
ERROR at line 1:
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-16052: DB_UNIQUE_NAME attribute is required
Below are the init file for the primary....

Did I configure something WRONG here? Seems like I did it right...
Some checks I ran...(primary)
SQL> select * from V$DATAGUARD_CONFIG
2 ;
DB_UNIQUE_NAME
peregrine
swesc
SQL> show parameter db_unique
NAME TYPE VALUE
db_unique_name string peregrine
Thanks.

Answer 1

I'm at a loss at what to do at this point then. When I run the following on the primary database, I get the following error.
SQL> connect /as sysdba
Connected.
SQL> alter system set log_archive_dest_2 = "MANDATORY service=SWESC reopen=30"
2 ;
alter system set log_archive_dest_2 = "MANDATORY service=SWESC reopen=30"
