OS: rm -rf \[archivelog  autobackup  backupset  controlfile  flashback  onlinelog\]  
eg :  
archivelog  autobackup  backupset  controlfile  flashback  onlinelog  
\[oracle@jibo PROD\]$ cd autobackup/  
\[oracle@jibo autobackup\]$ ls  
2014\_10\_13  2014\_10\_15  2014\_10\_16  
\[oracle@jibo autobackup\]$ rm -rf 2014\_10\_13  
\[oracle@jibo autobackup\]$ rm -rf 2014\_10\_15

RMAN:

RMAN> crosscheck backup;  
RMAN> delete expired backup;

RMAN> crosscheck archivelog all;  
RMAN> delete expired archivelog all;
