Please visit orapub.com, download the 'Ratio Modeling' paper for capacity
planning.
It's a quick and dirty method for estimating system capacity, be it CPU, RAM, disk, whatever.
Keep in mind that 'quick and dirty' is a relative term.
In addition, I highly recommend Craig's Capacity Planning course.

Subject: Sun/Oracle harware sizing tool
I am looking for a hardware sizing tool to determine adequate hardware for
our application that will soon be expanding from 25,000 active users, to
85,000 active users. At any given time I suspect I will not have anymore
than 500 users logged in at any one time, with 200 being a median .
Is there some equation for calculating the number of users that an
application serving tier can handle based on the processing power/number
of
CPU's and memory?
We are currently using Sun Solaris 2.5.9, RDBMS 9.2.02, Oracle
applications
11.5.7, HR only.
I am maintaining 4 instances , (3 copies of PROD generate little DB
activity) , on a Sun Sunfire 280R, dual processor, 8gb ram, and alot of
SAN
based storage for my DB tier.
I have a middle tier for each Instance on another Sunfire 280R , 2
processors, 8gb ram, application server discoverer etc...
For the pupose of covering the increased load, we are contemplating
acquiring 2 Sun 880Rs , 2-4 processors, and some multiple of 8gb ram for
memory, and clustering them for the DB tier requirements.
For our middle tier, we are planning using our existing s280r's , and
implementing load balancing... if that approach is still appropriate. We
have 3 now.
Any gotcha's with 9i RAC?
Oracle Applications requirements for this environment?
What would be a recommended migration path/approach?
Thanks All!
