as for
DD upgrades...<shrug>...praps the init.ora parameter compatible is not set
to the
newest version until the latest upgrade is in place? Just a guess.

  when freshly upgraded box comes online, lock manager doesn't have a problem   with different versions? And on related note, at what point is the data   dictionary upgraded? Having never done this, I'm rather   curious....

  You can do rolling upgrades on OPS, yes.   For quite some time, now....not a "new feature" either.

  Not 100% sure, but I don't believe you can do a "rolling"   upgrade in OPS configuration. All or nothing deal it   seems. I can't imagine DLM capable of operating with   different Oracle versions in multiple instances. My guess is, <FONT   size=2>you could upgrade one box in the cluster at a time, but you would need   to have a black out for the last box. Again, this is   only a guess.

  Any body have ideas on how a Oracle Upgrade is done in a 24*7   installation for a very large database specifically   using OPS.
