Below the ARCHIVELOG Mode checkbox is a list of up to ten possible log archiving locations. Enter USE_DB_RECOVERY_FILE_DEST as one of the destinations, to specify the flash recovery area as a destination. For ease of database management, the best practice is to use the flash recovery area as your only redo log archiving destination. You can, however, specify other locations on disk as well.
The purpose of the different log archiving locations is to spread your archive logs across different disks.
More info here:
1) Quota indicates the maximum number of 512-byte blocks of physical storage on a disk device that can be used by a local destination.
More details and an example on :
2) USE_DB_RECOVERY_FILE_DEST at destination #10 means that the archive logs will be written to the flash recovery area (That's the default).
You can specify the location and size of the flash recovery area on the same page in enterprise manager.
Do you really want to write your archive logs to multiple locations? -> do you have good reasons to do so?
To take maximum advantage of Oracle's features that automatically manage backup and recovery files and processes, configure your database as follows
- Use a flash recovery area, which automates storage management for most backup-related files.
- Run your database in ARCHIVELOG mode, so that you can perform online backups and have data recovery options such as complete and point-in-time media recovery.
- Use the flash recovery area as an archive log destination for your database (leave all archive log destinations empty, except #10 which points to USE_DB_RECOVERY_FILE_DEST)
I hope that this answers your questions at least partially?
