ORA-16009 Error in Alert Log

Question

Hi DBAs,
I saw the error ORA-16009 in alert log file. The database version is 10.2.0.3 configured with Physical standby on AIX 6.1 . The error is coming in alert log for a long time , I beleive after a swithover to Standby and switch back to Primary.
But I see the log from Primary to Standby are being applied and MRP is working fine on Standby Site.
I am posting the error message from alert log and trace file.

Answer 1

I have the follow setting for log_archive_dest_2 on Primary and standby which seems to be OK but above mention note which is for Oracle 9i server suggesting to disable the remote archiving on the standby database. Also I am using ASYNC option for log transport.
At Primary:
SQL> show parameter log_archive_dest_2
NAME TYPE VALUE
log_archive_dest_2 string SERVICE=STDBY LGWR ASYNC REOPEN=60 DB_UNIQUE_NAME=STDBY
At standby:
SQL> show parameter log_archive_dest_2
NAME TYPE VALUE
log_archive_dest_2 string SERVICE=PRI LGWR ASYNC REOPEN=60 DB_UNIQUE_NAME=PRI
Thanks
