The biggest thing was the move to a 64-bit server. Without a 64-bit
server thereís no way we could run databases of this size. You can
only redesign so much.

That said, even on 64-bit itís important to analyze your application
thoroughly to ensure that youíre being ìgentleî on the cache, that
your heavy database queries are all indexed, and that you optimize
your use of scarce resources (server side procedures, triggers, etc.).

But 64-bitÖ all you Mac people will be blown away when you try it for
the first time. So many problems immediately go away.

?when it became evident that your systems
were going to grow into these sizes, did you change anything in your
approach to 4D design? ?I know that's a broad question, but have you
seen
anything common in many 4D system designs that you know would present
problems if a system grew to the size you are dealing with?

It is really go to hear this. Combine this with Thomas Maul's post
that 64bit 4D Server v14 for Mac OS X is in the queue and expected to
be released this year, 2014 is going to be a good year for 4D Server
on Mac OS X.

I'm already planning on upgrading one client that runs Mac OS X
servers and they need more than a 2GB cache. =A0So happy the client
is
on maintenance so we can upgrade at our leisure. v14 requires at least
Mac OS X 10.7. So I've got to upgrade some old Mac Pros running 10.6
to 10.7. I'd love to jump directly to 10.9 but it's not possible with
some of these old Mac Pros -- they don't support EFI booting in 64bit
without some gnarly hacking. I'm just praying 4D does not change the
minimum specs for v14 64bit 4D Server on Mac OS X to require more than
10.7. (Top of my list of questions to ask the 4D engineers at 4D
Summit in Texas this year.)

Just running the server startup routines on this server consumes more
than 2GB of cache right off the bat. I can open it in 32-bit 4D and do
a few limited things, but anything substantial requires the 64-bit
engine.

I hope that once 4D is done modernizing things for the Mac that
they?=80&ocirc;ll move everything to 64-bit!
