Nahata,

My experience is a little dated, having not worked with 11i (just up through 10.5), however in my experience a n-node install would be preferable. At least when I was working with the Apps, it was a lot easier to size the database/concurrent processing server in terms of overall horsepower (memory/cpu) to get consistent performance, or at least know that at X time, there would be some slowdowns (usually when 1000+ reports got kicked off for month end). The form/web piece was highly variable in what it needed however. My isolating it on another server, it was a lot easier to demonstrate needing an additional forms server. I also found that the database/cm tier tended to be a lot more stable than the machine where all those web connections were being made. Using more than 1 web/forms server helped to work around unanticipated machine problems.

I was generally working with Financials (AR, AP, GL) and OE, with a little Manufacturing thrown in.

Just my $0.02.

Hi,

We are implementing Oracle Apps version 11.5.9 on Solaris with the following modules:
AR, AP, GL, FA, CM, Project Billing, Project Costing, PO, iProcure, iExpense

The anticipated load is:

	20 Forms users
	500 Web users

Should we go for 2 Node install or a single node install? I know the answer is "it depends", but what are the factors I should consider in choosing between the two?

Regards
Naveen
