In the middle of researching for a colleague, but thought I'd check here
too.
Database 9.2.0.4.0
OS HP-UX B11.00
Wanted to restore database to 9:15am server time this morning (5/10/06).
Last hot backup was (5/7/06). All database files and controlfiles were
restored and then he did this:

Customer said they did not see changes after 5/7. I had my guy run the
following query to check on the archive logs timestamps:
select to_char(first_time, 'DD-MON-YYYY HH:MI:SS') from v$loghist;
and the last few lines returned were:
04-MAY-2006 11:07:37
04-MAY-2006 11:08:24
05-MAY-2006 07:41:00
06-MAY-2006 10:01:17
07-MAY-2006 12:00:26
07-MAY-2006 03:00:09
It seems that the database was not rolled forward to the time he wanted.
And, of course, a new archive log has over-written the old archive log
because the database was opened noresetlogs and blah, blah, blah.
He has all the old archive logs and is now restoring the Sunday backup
again for attempt #2 and I am trying to help make this one successful.
Questions:
1. Should he see the archive logs being applied as it occurs? (I would
think yes)
2. Should he open resetlogs to avoid any archive/redo issues when
opening the database in the future? (Again, I lean towards yes given
what just happened to him :-) )
3. It seems to me the real problem is that he restored the Sunday
controlfile which only know about archive logs up to the time the backup
was taken. Therefore, the recover command completed almost immediately
without applying logs because there were no logs to apply. Soo, does he
recreate the controlfile and then issue the same command plus "using
backup controlfile"? Any other suggestions?
Thanks,
