Help interpreting Oracle RMAN results

backuporacleoracle-11grman

I am extremely new to Oracle and had to take a backup on an 11g database that is in NOARCHIVELOG mode. Below is the output. It claims that the backup failed but I have a file of appropriate size where I expected the backup to be created.

Can someone help me interpret this log?

Lets see what the Oracle supplied oerr utility says about you errors.

[oracle@testsrv Desktop]$ oerr ora 19804

ORA-19804 cannot reclaim %s bytes disk space from %s limit

Cause: Oracle cannot reclaim disk space of specified bytes from the DB_RECOVERY_FILE_DEST_SIZE limit.

Action: There are five possible solutions:
1) Take frequent backup of recovery area using RMAN.
2) Consider changing RMAN retention policy.
3) Consider changing RMAN archived log deletion policy.
4) Add disk space and increase DB_RECOVERY_FILE_DEST_SIZE.
5) Delete files from recovery area using RMAN.

ORA-19809 limit exceeded for recovery files

Cause: The limit for recovery files specified by the DB_RECOVERY_FILE_DEST_SIZE was exceeded.

Action: There are five possible solutions:
1) Take frequent backup of recovery area using RMAN.
2) Consider changing RMAN retention policy.
3) Consider changing RMAN archived log deletion policy.
4) Add disk space and increase DB_RECOVERY_FILE_DEST_SIZE.
5) Delete files from recovery area using RMAN.

Increase the db_recovery_file_dest_size size or specify format for the RMAN channel to different location.

Example

SQL> conn / as sysdba
SQL> alter system set db_recovery_file_dest_size=30G;

You should take care about actually disk space size of the disk which has defined as fast recovery area. If you want to store your back other location than flash recovery area then you can allocate channel as shown below.

RUN
{
  ALLOCATE CHANNEL disk1 DEVICE TYPE DISK FORMAT 'E:\%U'; 
  BACKUP DATABASE PLUS ARCHIVELOG;
}
