Hi Lorne,

First let me say one caveat....
I'm not an Oracle backup expert...

You migth want to post to contact Oracle if you have a support agreement. There migth be something else you can do.

Here's what I think happened...
Did you restore a control file? If you did you should try to restore only the
data files (hence the non existant archive log file..)
Easier is if you have a nigthly export file in addition to standard backup? I find the export files easier to work with
then a full backup for partial restores...

You should be able to do a complete or cancel based recovery..

You need..
-dbf files from yesterday
-control file from today is ok or backup controlfile taken using "alter
database backup controlfile command"
-All archived logfiles ( not redologs ) since your yesterdays dbf file
backup

If you meet this requirement,
you can go for either complete recovery (only your current control & redologs are intact ) or cancel based recover ( If U lost your current controlfile and redo log groups ) or timebased recovery....I haven't got time to explain
all in detail but they are covered in the manual..

Hope that helps..
