Bug 5207044  RMAN "backup validate check logical" fails with OERI[krbbfmx_notfound]
Range of versions believed to be affected Versions < 11 
Versions confirmed as being affected 10.2.0.3 

 

ORA-600 [krbbfmx_notfound] can occur during RMAN backup of
locally managed datafiles.

 

Workaround:
 Disable undo optimization by using:
 - BLOCKS ALL qualifier in backup command,
   ie. backup blocks all database
   This disables unused block optimization for the backup command only.
 or
 - Set "_unused_block_compression"=false as an initialization parameter.
   This disables unused block optimization for all backups until removed.
