Specifying whether to dismount the tape  Protecting dump files from being overwritten

Chapter 12: Backing Up and Restoring User Databases

Rewinding the tape

By default, both dump and load commands use the nounload tape handling option.

On UNIX systems, this prevents the tape from rewinding after the dump or load completes. This allows you to dump additional databases or logs to the same volume or to load additional databases or logs from that volume. Use the unload option for the last dump on the tape to rewind and unload the tape when the command completes.
