cd $ORACLE_HOME/bin
./rman target /

RMAN>startup nomount;
RMAN>restore controlfile from '/u01/app/oracle/flash_recovery_area/DPC11/autobackup/18_8_2011/o1_mf_s_759472776_74sn369s_.bkp';
RMAN>alter database mount;

then I crosscheck
crosscheck backup;
crosscheck copy;
crosscheck backup of database;
crosscheck backup of controlfile;
crosscheck archivelog all;

Then I catalog all backup piece all pieces are successfully catalog except 1 i.e.
CATALOG backuppiece '/u01/backups/klmj1c3r_1_1';

Catalog a previous backup of this file, if you have any.
Otherwise, skip the tablespace that contains this file.

Hey Hi,

I also faced this problem few days back.
Did you try again catalog that particular piece ??
Usually if there is no any error in rman logs (when taking backup through RMAN ) so you can retry to catalog and it will be catalog.
