Question about set local redo log path in DG

Question

i see doc says that:
If a fast recovery area was configured (with the DB_RECOVERY_FILE_DEST initialization parameter) and you have not explicitly configured a local archiving destination with the LOCATION attribute, Data Guard automatically uses the LOG_ARCHIVE_DEST_1 initialization parameter (if it has not already been set) as the default destination for local archiving.
and i active the function of fast recovery area,
SQL> show parameter DB_RECOVERY_FILE_DEST;
NAME TYPE VALUE
db_recovery_file_dest string /opt/app/oracle/flash_recovery
_area
db_recovery_file_dest_size big integer 2G
that's mean that i should set LOG_ARCHIVE_DEST_1 as DB_RECOVERY_FILE_DEST or i have not set LOG_ARCHIVE_DEST_1 ?

Answer 1

Technically you do not need to set LOG_ARCHIVE_DEST_1 because oracle will use it as the default setting for archiving the logs since you have DB_RECOVERY_FILE_DEST set, but it's good practice to explicitly set it so that's it's easy to look up.
alter system set log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST' scope=both sid='*';
