Re: Upgrade oracle first or upgrade ML11 first

One might expect that the Oracle upgrade would contribute more potential
problems than the application of a new AIX ML. It might be prudent to
upgrade Oracle first to isolate issues in order to prevent the "we
upgraded two things at once, we've got a problem, let's blame the O/S"
argument.

A lot depends on your testing/validation procedures.

You may have middle-ware consequences to consider, too.

Let QA decide. :-)

I would not do testing until after both the OS and oracle is patched.
It seems that a test of patched oracle and unpatched OS is useless when
you
will not be running it that way once you upgrade the OS.

Likewise vice versa, testing unpatched oracle with a patched OS is also
not
a valid test, as it is not indicative of what the environment will be in
finality.

I am also with simon on the backout procedures, I would put much more
emphasis on what to do if something goes awry.

Assuming that there are no dependencies, then I don't think it makes
much
difference.

Maybe you'd like to consider back-out scenarios. The order in which you
do
the upgrade could affect these.

You might take the view that doing the AIX ML11 first is best. It's
relatively trivial so you can get that done then leave the DBAs to it.
