Chris,
RMAN duplicate recreates the controlfile as part of the duplicate process.
This happens after the datafiles are copied to the target server/database.
Are you getting a specific error from RMAN? i ran into a similar situation
recently where RMAN complained that it couldn't find any datafiles to restore
and went back a few backups to do the restore. I eventually ended up doing a
log switch on the source database and then it would use the backup i was
expecting it to use.
Hope this helps.
Haroon

Well, thats just it, I don't think its actually restoring
the controlfile autobackup. I don't specifically tell RMAN to restore it,
which I think is part of the problem.
Joe mentioned the backups might be expired (which I think
they are since I had to restore them from tape).
I seem to remember running into this before, but I cannot
remember how to restore the controlfile autobackup when using a
catalog/repository during a duplicate.

Chris,
What does the log look like when you run the duplicate? In
particular, which controlfile autobackup is getting restored during your
duplicate? Make sure that the April 30th controlfile is being
restored.

I have a need to create a test db clone from May 1st 2009 at 7:30 AM.
I have the RMAN full backups from April 30th 8:16PM and May 1st 8:30 PM.
I am using an RMAN catalog.
Here's my RMAN script:
run
{
allocate channel d1 type disk;
allocate channel d2 type disk;
allocate channel d3 type disk;
allocate channel d4 type disk;
allocate auxiliary channel a1 type disk;
allocate auxiliary channel a2 type disk;
allocate auxiliary channel a3 type disk;
allocate auxiliary channel a4 type disk;
set until time="to_date('05/01/2009 07:40:00','MM/DD/YYYY HH24:MI:SS')";
duplicate target database to f9tst
logfile
GROUP 1
(
'G:\oracle\oradata\F9TST\onlinelog\redo01a.log',
'F:\oracle\oradata\F9TST\onlinelog\redo01b.log'
) size 25M,
GROUP 2
(
'G:\oracle\oradata\F9TST\onlinelog\redo02a.log',
'F:\oracle\oradata\F9TST\onlinelog\redo02b.log'
) size 25M;
}
Now RMAN is complaining that it cannot find backups which I believe are more
current than the ones I have. (Meaning they were taken from May 2-10th...It
seems that RMAN rolls back to previous backups starting with the current one
and maybe only tries 3 days worth perhaps?)
I have the controlfile autobackups from 4/30 and 5/1 as well.
I need some suggestions here as I seem to be missing something.
