Re: Local Partitioning

Question

Hi,
If you intend it on the first time you make a partitioning,
just define your client node as Client only on the environment. So
the environment visible service objects will automatically be assigned
to server nodes.
Hope this helps.

I was wondering if anybody knew how to force a Service Object to be
partitioned onto the server without it being a DB service object or C
shared library when partitioning for a local run instead of running
distributed?
Greatly appreciate it.

Another useful reply! What a great news group this is.
One last thing I wanted to ask about, though, is global vs. local. I see you
talk about globals, but in fact the variables in my subVI's were locals. I can
easily understand the behavior I observed accompanying the use of global
variables, But I guess the use of the word "local" stumped me.
Should I interpret "local" in LabVIEW's sense to mean "local to all instances
of this VI"? And global to mean "visible to all instances of this VI as well
as other VI's"?
