RE: Recovery Issues :)

Hi Paula,  

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: http://dizwell.com/main/index.php?option=com_jd-wiki&Itemid=138&id=direc tpathoperations  

Hope that helps,  

-Mark

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 :)!
