A shoot-out has erupted between your MS development teams using .NET and your Linux
development teams using Java. Knowing that your database is in danger, which command would you use to back up your
NOARCHIVELOG mode database using RMAN with compression?
A.
backup database all
B.
backup compressed database
C.
backup as compressed backupset database;
D.
backup as compressed backup database plus archivelog all;
E.
backup as compressed backupset database plus compress archivelog all;
Explanation:
RMAN-03009: failure of backup command on ORA_DISK_1 channel at
02/23/2014 11:46:01
ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode
RMAN>
Is the quiestion correct ?
“backup database all” is not correct command
RMAN> backup database all;
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

Also you can use “backup as compressed backupset database;” if database is in mount mode :
RMAN> alter database mount;
database mounted

RMAN> backup as compressed backupset database;
