Flashback database in Dataguard environment

Question

On primary if i flashback database to a restore point, do I need to rebuild standby environment. Is there any other option. Can I flashback standby to restore point also. Can you please detail me the steps.
These I think are the steps.
1) Create Flashback database Guarantee restore point on Standby.
2) Create Flashback database Guarantee restore point on primary.
Backout
1) Flashback Database to restore point on primary.
2) Flashback Database to restore point on standby
Is it possible if we follow the above steps we dont need to rebuild the standby after flashing back the primary database.

Answer 1

If I flashback database to a restore point, do I need to rebuild standby environment?
No, since the standby database should be synchronized to the primary (assumes no delay) it should come along for the ride.
Can I flashback standby to restore point also?
Yes, but the retention period must be greater or equal than the Primary database retention period.
There are very few cases where you would want to do this on the standby.
For example you might use it if a RESETLOGS was used on the Primary.
Setup
Guaranteed restore points provide a complementary capability to Flashback Database.
You might set them up during an upgrade.
Ex.
CREATE RESTORE POINT before_upgrade GUARANTEE FLASHBACK DATABASE;
FLASHBACK DATABASE TO RESTORE POINT before_upgrade;
Section 5 of B14192-03 has some good information on this.
This is worth a look too:
