Errors RMAN-03009 ORA-19809 ORA-19804 When doing a backup

If you are trying to do a backup of your database and are receiving these errors below:

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

RMAN-03009: failure of backup command on ORA_DISK_1 channel at 01/11/2010 11:27:28
ORA-19809: limit exceeded for recovery files
ORA-19804: cannot reclaim 52428800 bytes disk space from 5218762752 limit

Check if you are using the db_recovery_dest as the backup destination and if yes, increase the value of db_recovery_file_dest_size initialization parameter to a value that could behave your database size.

Example:
alter system set db_recovery_file_dest_size=15G scope=both;
