How to turn on Archive redo log mode for 10g

Hi,

Do you guys know how to turn on Archive redo log mode for 10g,

I alter my database already, here is my pfile created from my spfile.

I have this error
ORA-16019: cannot use db_recovery_file_dest with LOG_ARCHIVE_DEST or LOG_ARCHIVE
_DUPLEX_DEST
*.db_name='Ora10g'

*.db_recovery_file_dest='C:\MyOracle\product\flash_recovery_area'

*.db_recovery_file_dest_size=2147483648

*.dispatchers='(PROTOCOL=TCP) (SERVICE=Ora10gXDB)'

*.log_archive_dest='C:\MyOracle\oradata\Ora10g\archive'

*.log_archive_start=TRUE

*.undo_management='AUTO'

*.undo_tablespace='UNDOTBS1'

*.utl_file_dir='C:\MyOracle\oradata\utl'

Thanks and Regards,

Sin
