server upgrades, informix configuration changes

[dmaranan]

I'm adding an extra processor to a single processor machine and I'm adding 512 MB to an existing 256MB machine.

Do I need to make any major configurations on any of the informix files?

You could set the
MULTIPROCESSOR=1
NUMCPUVPS=(Number of CPUs -1)

The settings depends on your Informix Version.
9.x is different to 7.x

Also You can increase the
SHMVIRTSIZE
SHMADD

since you now have more memory.

Of course this is not essential, as Informix will use your new memory anyway if you have SHMTOTAL=0
