Mistake during Oracle 11g PITR I tried using set time until.. and mis-typed the date.  Can anyone help me understand how to get my backups into a manageable state?

After the accidental recover, most of my backupset disappeared.

I recovered them and used 'catalog recovery area' .. and they're listed in 'list backupset'.  But something still isn't right.

When I do a PITR now, I get messages that my dbf files aren't available

and... the 'list backupset' seems to show backupsets.  But they are listed differently than the files which weren't included in the 'bad' recovery.

Gists with the error and the list of backupsets are here https://gist.github.com/akinsgre/5561254
So after working through the info that Phil gave me.. and doing some research after the fact..

It appeared that the Set Until with a future date screwed things up by "removing, or de-cataloging my backups".  Even if that's possible (I don't know enough about Oracle to say) it wasn't the case.

What had happened was that my initial Full Backups were gone due to some poor data-retention.  So when I put a future date, it appeared like my PITR would work because it had a Full backup from a day ago.  However, I never did have a Full backup from a week ago.     I had taken one a couple months ago. but it had been deleted.

I'm using EM Console for my backups and haven't yet figured out how to tell it to do incrementals every day and fulls once a week.  I'll get there though.  

Thanks for all the help.
