If no quota is set for archive area, this is calculated through the UNIX df –k command.
If quota is set:
total archive area = quota_size * db_block_size (in KB)
Oracle recommends that multiple archivelog destinations across different disks be configured. When at least one archivelog destination gets full, Oracle recommends the following:
If tape is being used, back up archivelogs to tape and delete the archivelogs.
If tape is not being used, back up the database and remove obsolete files. This also removes archivelogs that are no longer needed based on the database retention policy.
If archivelog destination quota_size is being used, raise the quota_size.
