Interrupting Flashback Database

So a user called me up and said he was flashing back a database and he was not too happy with the amount of time it was taking to complete the operation and so he did a Ctrl-C...

When he tried to open the database this is what he saw..

==================================================================================

SQL> shutdown abort
ORACLE instance shut down.
SQL> startup

===>... Well he just turned off flashback..

SQL> alter database open resetlogs;

Looking through the alert.log

Fri Sep 18 08:35:05 2009
flashback database to restore point TEST_AFTER
Fri Sep 18 08:35:05 2009
ORA-38757 signalled during: flashback database to restore point TEST_AFTER...
Fri Sep 18 12:00:48 2009

No errors in the RVWR process trace file

So I just dropped the restore point and voila

> drop restore point TEST_AFTER;

Restore point dropped.

> select flashback_on from v$database;

FLASHBACK_ON
------------------
NO

> alter database open;

Database altered.
