How to flash the database back to a guaranteed restore point

After a week of testing their new release, my customer wanted their database reset to the state it was previously in.
Earlier this week, I created a restore point of type GUARANTEED FLASHBACK.

Here is how I restored a database using flashback database technology. It was, as expected, very quick. Only a few seconds to flash back 14 GB of changes.

Connect to Recovery Manager:

oracle@myserver:[TESTDB01]# rman target / catalog uid/pwd@rmancat

Recovery Manager: Release 11.2.0.4.0 - Production on Thu Nov 20 16:06:44 2014

connected to target database: TESTDB01 (DBID=411134280, not open)
connected to recovery catalog database

RMAN> list restore point all;

SCN              RSP Time  Type          Time         Name
---------------- --------- ----------   ---------     ----
153050263689                GUARANTEED  17-NOV-14     AKSEPT_TEST_START

Start the flashback operation:

RMAN> FLASHBACK DATABASE TO RESTORE POINT AKSEPT_TEST_START;
Starting flashback at 20-NOV-14
