It was going so well. The problem is a chunk of missing archived logs,
so I'm unable to apply them. :-(

Which is, unfortunately, the point I can't get to. System data file
needs additional recovery.

All files are online at the same SCN, date & Time according to
v$datafile_header. All files are still in "RECOVERY" status according to
V$RECOVER_FILE.

I have the rman backup and the backup of all the archived logs from
before, through and just after  the backup of the datafiles. 

Well, I did have. I've blown them all away now and restarted the rman
backup. Better luck this time I hope!



Cheers,
Norman.
