Hi Mary Elizabeth,
Right now we have an 11.1.0.7 EE RedHat physical standby setup. It's
not RAC or ASM, so not 100% what you're looking for, but hopefully
still be helpful...
I haven't encountered any gotchas...The only ones I am aware of are
the same as any setup - the bugs that exist for each version and
product..(including DG specific patchsets).
For standby creation, I typically use a hot backup script or an image
copy; but a duplicate (duplicate target database for standby) would
work just as well.
Personally, I think the offerings of DG (e.g. fast-start failover) are
definitely worth any extra pre-prod testing you may be inclined to
perform based on your predecessor's setup.
