I'm running an EM clone right now. I've done it before and it is pretty reliable. It didn't like the existing tnsnames.ora on the system because it had been modified but not by em. The solution was to create someplace else for the network/admin/ stuff, which I did, but which I don't like. Life is so much easier when you stick to standard locations. I'll have to see if the files can be moved where they belong once the cloning process is finished.
The data guard / flashback are probably wonderful the 5th time you have done them. Isn't that the way with all our procedures?

Ah right, a combination of DG and flashback which I did hear mentioned somewhere this week. I might see about trying that out but it does sound rather complex and time-consuming Having used duplicate database before I really think that is the way to go, although as I said in my last post the EM clone option seems quite good as well.
If anybody cares to try out the whizz-bang approach then feel free to blog about it.

I saw Lutz Hartmann give a demo of that at 2007 Open World on a toy database. It looked really wiz-bang. His demo also involved ASM in the mix. I took notes intending to try it out, and then didn't.

That sounds like
- setup standby - physical
- open standby read-write at time x
- do stuff
- flashback to before x
- resume standby
