Hi,

Is anyone using 11i in pre-production release for the PO application?

We are researching the impact of an upgrade from 10.7 SC, and need more
than the public information disseminated by Oracle, if possible.

Thanks!

We went from 10.7SC to 11.02, and it was a monster jump... It took
months for the user screams to die down to a dull roar... 10.7 to
11i is an even huger jump--two releases later.

Hope your upgrade goes well. Best of luck.

Bob,

Thanks for the [grim] input :-)  but wasn't the performance better?  Did
the users find any apps interfaces that had changed drastically?  It is
my understanding that most aspects "look" the same, but the background
processes (not to mention the 3-tier architecture) work much better in
most implementations.  So why were the users screaming?

Thanks - Tom

Actually, the performance took a major nosedive for us :(  Our
DBA/sysadmin spent about a month pulling out his hair, tuning
everything he could think of, trying to get better performance.
He brought in tuning consultants from Oracle Consulting, and
OS performance consultants from HP... It was pretty ugly for a
while there.

I don't know the specifics of the eventual fix (I'm just an
apps programmer), but it had something to do with the
R11 self-serve web apps hogging system resources... The good
news for you is that we upgraded to 11.02 in the first wave,
last year at about this time. We'd open TARs with Support,
and unfortunately, most of the Support people at that
point were less familiar with R11 than we were... Obviously,
that won't be the case with your upgrade, although if you
go to 11i soon after it's first released... Well, you may
experience something similar.

The biggest change (apart from the initial performance problems)
was the switch to 'floating forms', i.e., each form you open
is in its own window. So as you open forms, when you eventually
get to the form you want, instead of having one Oracle Apps
icon down in the start bar tray, you have an icon for every
single form you've opened already. That takes a little getting
used to for users, but they do get acclimated to it after a while.
It's a bit more confusing when you've got more than one instance
up (production and development, for example)... I find myself
checking 'Help->About Oracle Apps' with just about every form
to make sure I'm working in the right instance...

As for performance overall, after the DBA figured out the problem
with the self-serve web apps, I'd say the performance is about
back to the point it was when we were on 10.7. Not noticeably
faster, IMO.
