[SOLVED] 10g RMAN Point-in-time recovery
I'm attempting to practice a RMAN based DB PITR using Oracle XE and am not getting the expected results. The scenario is such:
1. Create an instance and set ARCHIVELOGS and enable archiving.
2. Create a table.
3. Back up the database with RMAN (NOCATALOG mode).
4. Note the SCN from V$DATABASE.
5. Drop the table.
6. Execute RMAN restore/recover with a SET UNTIL SCN = the scn from step 4.
The problem is that RMAN throws an error saying it can't find any datafiles to restore, which seens wrong -- it should be able to restore the datafiles and roll forward to the appropriate SCN.
Create table BAR.
Run backup (list backup output below):

The backup is performed with the standard 'backup database' script provided with XE, which ultimately does a 'backup database' command in RMAN.
Any ideas why this might be failing?
