Title: RE: Rolling Upgrade of Oracle on a 24*7 implementation

Gary,

 

i wish i knew the answers to those good questions.

 

Consider though, that until recently the DLM was the job of the OS vendor

NOT the dbms vendor and so a dbms version tick changed nothing in that

regard.

 

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.

 

For a real answer, you'd have to open an iTar, and head to Tibet to meditate

yourself into Perfect SelfTranscendence before getting an answer from the hamster

running MetaStink.

So, 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,
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.
