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 (See ORA-26040.ora-code.com). 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: http://dizwell.com/main/index.php?option=com_jd-wiki&Itemid=138&id =directpathoperations
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 :)!
