In a Snapshot Standby environment, the archive logs are not applied as they come in and are pooled or stored in the archive log directory of the standby until they are all applied. A snapshot standby has a 1:1 mapping in terms of the file and storage layout from primary to standby. A Snapshot Standby database is typically open in read-write or Active Standby mode for accessing the data. However, it has to switch back to mounted mode in order for the pooled archive logs to be applied to the database.
