I feel a bit confused when I read about RMAN!
what are the differences between:
RMAN> backup as backupset
RMAN> backup database;
RMAN> backup database plus archivelog;
RMAN> backup as backupset database include current controlfile;
what is the difference between backup database and backup as backupset
also how to backup the database + needed archivelog + controlfile + spfile in one command for a full restore when needed?
is there any site explains this stuff in details with examples?
