Patrick,
Jason and I already told you that you can't do a rollforward when you have
opened the database in r/w because you then need to open the database with
resetlogs (the same as with an incomplete restore).
You can however open the flashbacked database in read only mode, shutdown it
again, mount it and then do a rollforward.

Lee,
I had to do a reset unless I wanted to use a backup control file which, I did
not want to go there...
SQL> FLASHBACK DATABASE TO TIMESTAMP timestamp'2010-03-02 10:13:40';
Flashback complete.
SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-01589: must use RESETLOGS or NORESETLOGS option for database open
SQL> alter database open noresetlogs;
alter database open noresetlogs
*
ERROR at line 1:
ORA-01610: recovery using the BACKUP CONTROLFILE option must be done
SQL> alter database open resetlogs;
Database altered.

I am thinking you shouldn’t have issued your resetlogs, however my knowledge of
flashback stuff is limited to say the least ☹ ??

Jason,
Good to know about the flash forward until; thanks!
What commands/processes did you use?
This is what I did and I had problems. Any thoughts?
Shutdown immediate;
startup mount;
FLASHBACK DATABASE TO TIMESTAMP timestamp'2010-03-01 09:41:49';
alter database open resetlogs;
SQL> RECOVER database until time '2010-03-01:09:42:38';
ORA-00283: recovery session canceled due to errors
ORA-19907: recovery time or SCN does not belong to recovered incarnation

Hello Patrick,
Been testing flashback a bit recently so when I saw your email thought
I would test. Tested this with 10.2.0.4 on linux, and yep you
definitely can flashback and then roll forward, I did a recover
database until change to roll forwards again.
As Freek pointed to open read-write a flashed back database you need a
resetlogs, but of course you can open read-only without this.
Once you have flashed back you can even use flashback database to
"flash forward" and undo your flashback.
jason.
