startup command, specify the MOUNT option to startup; else if you are directly
doing an ALTER DATABASE DISMOUNT, do nothing; else specify the MOUNT
option to ALTER DATABASE. If you are doing a backup or copy, you must first
mount the desired database. If you are doing a FLASHBACK DATABASE, you
must first mount the desired database.
