Rman point in time recovery

Question

Windows server 2003
Oracle 10g
Hi all please help.
I'm doing a reorg so I exported the production schemas and droped the schemas so that I can import the data again, but I dropped one user with out exporting it first!. I have no full exports but archivelog is enabled.
I want to do a point in time recovery :
RMAN> RUN
2> {
3> SET UNTIL TIME 'DEC 12 2009 04:00:00';
4> RESTORE DATABASE;
5> }
executing command: SET until clause
using target database control file instead of recovery catalog
Starting restore at DEC 13, 2009 13:30:53
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=541 devtype=DISK
allocated channel: ORA_DISK_2
channel ORA_DISK_2: sid=540 devtype=DISK
creating datafile fno=1 name=E:\ORADATA\JDE\DATA\SYSTEM01.DBF
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 12/13/2009 13:30:58
ORA-01180: can not create datafile 1
ORA-01110: data file 1: 'E:\ORADATA\JDE\DATA\SYSTEM01.DBF'
Just prior to this i did a restore/recover with a sequence nr, no problem but it didn't work, the schemas still wasn't there, so now i want to use a timestamp.
Please help this is a production database
RUN
SET UNTIL sequence 5657;
RESTORE DATABASE;
RECOVER DATABASE;
}

ORA-01180: can not create datafile 1Basically this error means RMAN 'thinks, I have no backup of datafile 1 and will try to create datafile 1. Afterwards I will apply archivelogs to the newly created datafile' . But that is not possible for datafile 1.
By the way instead of 'DEC 12 2009 04:00:00', I would always use something like
"TO_DATE('DEC 12 2009 04:00:00','MM DD YYYY HH24:MI:SS')" .
So you are sure the date is always interpreted correctly - independent of your default format settings.
