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?
RMAN uses backupsets by default. The following commands will create a backup to a backupset:
RMAN> backup database;
RMAN> backup database plus archivelog;
This is assuming that you haven't changed the default RMAN parameters:
RMAN> SHOW ALL;
...
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
"Backup as backupset" is not a valid command and will return a syntax error.
"Backup as backupset database include current controlfile" might be useful if you changed the default backup type to something other than a backupset (e.g. "BACKUP TO COPY").
I suppose that you looked at the Oracle site (http://docs.oracle.com/cd/B28359_01/backup.111/b28270/rcmquick.htm)? If not then look here: http://www.thegeekstuff.com/2013/08/oracle-rman-backup/.
