Hi Keith,
I have to second Carels and Michaels meanings. Your desire is highly
complex and multi dimensional. So you will not get any straight
forward answer.
In one of my prior lives I had to promote and support Multi Master
Replication. If someone uses this wise, he can achieve a zero-downtime
environment.
But be warned: You need a tremendous engineering work and still really
good skilled operational DBAs with enough time to take care of.
I have never checked, wether or not streams can provide the same
functionality. Maybe it's worth checking.
just some ideas, might they help,
Martin

Hi, I'm working with a customer running a critical web site on a
10gR2 RAC backend DB - they support hundreds of thousands of
simultaneous connections at the "quietest" time.
They have expressed a desire for NO downtime during ANY changes to
Oracle, particularly the application of Oracle patches and Oracle
upgrades (both minor and major), etc.
Any thoughts? Who's "been there done that"?
