Hi,
My application are a compiled stand alone OEM application, can run on
sigle mode or in client-server mode.
I know all hardware that run my application, so i can set the memory
cache in better mode.
Is even true that number of records are not the same for all the
installations, and i have the issue only for the greater installation (
1.700.000 size of datafile with the greatest table have 4/5 milions of
records ).
Thanks

Adaptive cache
Percentage of available memory for cache
Minimum size
Maximum size
Adaptive cache was a feature designed for OEM 4D applications.
Say you have a 4D product that is used by say 100 different customers. You
don’t know what server hardware each customer has. Some customers have 4GB
machines, some have 8GB machines, some have 32GB machines. Some customers run
only 4D Server on the machine, some also use the machine for file server
operations. Some customers have 1GB 4D data files, some have 4GB data files,
etc.
You create new version of your 4D application and want to send it all 100
customers. What 4D data cache setting should you use? Literally every customer
should have a different setting. Adaptive cache setting is for this situation.
You want to give 4D some guidelines on how to use the memory on the server
machine.
If the above describes your 4D application situation then using Adaptive cache
would be a good thing.
If you have a single 4D application and it is deployed on a single machine,
then Adaptive cache does not provide a big advantage for you. I would turn off
Adaptive cache in this situation and just set the 4D data cache size based on
how much RAM is in the server machine.
All my 4D applications are deployed on a single machine that I have total
control over. So I never use Adaptive cache. See my previous post for details
on how to configure 4D’s data cache size. I’m don’t have experience on what
are “good” settings for Adaptive cache since I never use it.
Here’s a great question? What 4D developers out there are actually using the
Adaptive cache setting for deployment of a 4D application to multiple
customers? Any of you care to reply to Ferdinando’s question and give home some
advice?
