Symptoms


RMAN looks  for the datafiles to backup and identifies that the datafile doesn't exist any more ( dropped ) that cause the backup to fail.

The question is,
Does any workaround/patch exist so rman does not fail and exit, but to continue the backup with error message,
or warning that the Tablespace / Datafile was dropped after backup has started and so not available.


Error:

RMAN-03002: failure of backup plus archivelog command at 02/05/2013 12:51:00
RMAN-03009: failure of backup command on ch01 channel at 02/05/2013 12:51:00
ORA-01157: cannot identify/lock data file 5 - see DBWR trace file
ORA-01110: data file 5: 'No file with this number, file does not exist'

 

or:

RMAN-03002: failure of backup plus archivelog command at 02/06/2013 15:55:27
RMAN-06056: could not access datafile 5            <<-- This tablespace/datafile was dropped after rman backup was already started
