Error while taking RMAN back up - RMAN-03009: failure of backup command ..

Question

Hi Experts,
I am trying to take RMAN back up but at the end I get this error message.. I found a solution at http://www.oracle-base.com/articles/9i/RecoveryManager9i.php
But this is of oracle 9i. Can I use it on 10g too ?
So is this Step correct ?
1) First create a user to hold the recovery catalog:
a) CONNECT sys/password@w2k1 AS SYSDBA
b) GRANT connect, resource, recovery_catalog_owner TO rman;
2) Then create the recovery catalog:
a) C:>rman catalog=rman/rman@w2k1
b) RMAN> create catalog tablespace "RMAN";
c) RMAN> exit
3) Register Database
a) C:>rman catalog=rman/rman@w2k1 target=sys/password@w2k2
b) RMAN> register database;
c) Existing user-created backups can be added to the catalog using: (*So far no Back up taken so I guess this step can be ignored*)
i) RMAN> catalog datafilecopy 'C:\Oracle\Oradata\TSH1.dbf';
ii) RMAN> catalog archivelog 'log1', 'log2', 'log3', ... 'logN';
4) Full Backup Configuration
RMAN> configure retention policy to recovery window of 7 days;
RMAN> configure default device type to disk;
RMAN> configure controlfile autobackup on;
RMAN> configure channel device type disk format 'C:\Oracle\Admin\W2K2\Backup%d_DB_%u_%s_%p';
5) Full back up
RMAN> run {
backup database plus archivelog;
delete noprompt obsolete;
6) RMAN> resync catalog;

Answer 1

Provided you consult the 10g RMAN documentation and the online error documentation: yes.
But apparently you didn't check documentation, not even the error messages!!!!! Why?
You are backing up to the Flash Recovery Area, and the error messages mean too much space is occupied.
How to configure the Flash Recovery Areea is fully documented in the Backup and Recovery manual for 10g at http://tahiti.oracle.com
READ IT.
Please do not ask a volunteer to abstract it.
