  Ok, it sounds like you've successfully recovered.  Now, the problem w/ the 
"missing" rows.  This may be where NOLOGGING is relevant.  How is this data 
loaded?  If it was done as INSERT /*+ APPEND */, then the problem is that, with 
nologging set, the data was not in the archive logs you applied, so, the 
segment will need to be truncated and reloaded.  Ideally, the table is 
partitioned (is it?) so that you can truncate and re-load just that partition.  
Right now, if you do a full table scan of the segment, your query will 
eventually hit the logically corrupt blocks and raise an ORA-26040.  The only 
way to get rid of those corrupt blocks is to either drop or truncate the 
segment containing them.
   
  For more info on direct load, nologging, and recovery implications, see:

  Hope that helps,

  Okay,
   
  We used the following syntax to recover a database 
   
  ALTER DATABASE RECOVER DATABASE UNTIL TIME '2006-05-10:09:00:00' USING BACKUP 
CONTROLFILE
   
  Some of the archive files said "no longer needed for recovery"
   
  Now, we are told there are rows missing from the night of the 9th (i.e. the 
night before).  
   
  Help :)!
