I know some of you folks have large SMPs as the result of consolidating
a lot of little SMPs into one large one for managability sake. What
about distaster
recovery?  If you have, say, 20 databases in a large SMP, do you set up
20 "streams" of
DG to a DR site?  Is that a nightmare?  Are there any sites out there
that have, say, more
than 10 databases that require disaster protection where DG is the tool
of choice? Or
do such sites opt to replicate at the storage (or volume e.g., Veritas
VVR) level?

Yes, Carel-Jan will remind us  that replicating at the storage level
requires replication of
all writes as opposed to just sending redo pieces...

Thoughts ?
