Your database has to be in archivelog mode for RMAN.

Subject:        checking for block corruption
Sent by:

I need to run a block corruption test. I have a BCV copy of prod I am running this on. We are not using RMAN for prod backups. I can't change this.
DB Version:
DB Size: 10 TBs
files are on raw partitions
rman target /

backup validate database;

if I run this will this actually backup the DB? When I read the docs they seemed to say it would only do a validate check. We have the DB copy in noarchivelog mode.
When I ran that command I get:

RMAN-03009: failure of backup command on ORA_DISK_1 channel at 05/21/2012 16:05:09
ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode

If backup validate only checks for block corruption why does it care if I am in archivelog mode ( i know i can bounce the db or turn it off. I want to make sure I'm not actually taking a backup).
