Hi List,
This is 11.1.0.7 on RHEL 5.1 (external application requirements).

I don't know if this is related, however, this started with only incremental backups failing with:
ORA-19643: datafile 6: incremental-start SCN is too recent ORA-19640: datafile checkpoint is SCN 656412919 time 02/27/2015 06:46:55 (sometimes datafile 83 and different SCN numbers)

Fulls were OK until just recently; they now fail with: ORA-00001: unique constraint (RMAN.DF_P) violated

No changes to backup scripts which are fairly standard - the logfile and error stack (for a full) is:
RMAN> run {

2>         show all;
3>         backup incremental level = 0 database plus archivelog delete
input tag Full_DB_20150304_062126 ;
4>         delete noprompt force obsolete ;

5> }
starting full resync of recovery catalog

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of show command at 03/04/2015 06:21:31

RMAN-03014: implicit resync of recovery catalog failed RMAN-03009: failure of full resync command on default channel at 03/04/2015 06:21:31
ORA-00001: unique constraint (RMAN.DF_P) violated

Google and MOS have been little to no help...did find Bug 9288598, however, this is not a standby and I don't think it ever was. Support is also "working" on this, however, not much there either (just sent them log files and a debug).

We do see that these datafiles (6 & 83) as well as some others have UNRECOVERABLE_CHANGE# populated and UNRECOVERABLE_TIME with a date back in 2013. This looks to me like there was some NOLOGGING activity back then, but I don't think this should be an issue?

Any ideas?

Thanks,
Rich
