You can use archive log backups to recover database transactions that have been lost due to an operating system or disk failure. Apply the archive logs to an online backup to recover a database.
By default, full backups include both data and archive logs, but you can also perform separate archive log backups.
Procedure
On the RMAN command line, run the following sample script, substituting any required or optional Oracle parameters. For information on required and optional parameters, see Oracle Agentless SBT Parameters for RMAN Jobs.
