Re: Standby for testing and Flashback

Ravi,

In 11g, Oracle introduced a new concept of 'Snapshot Standby Database/Active Standby' which enables you to open standby in RW mode (for testing, development purpose) and easily revert back it to standby mode again.

However, in 10g, it is very well possible, In fact, I did discuss this on my blog :

Mr. Alejandro documented the above clearly at this presentation:
