Memory parameters



We have installed 4 SAP components(R/3,Xi,EP,BIW) on single OS (HP-UX)with Oracle. System perfectly working but little bit poor performance.

During installation we have given 8GB memory for all the compoennets , that means each instance 2GB ( 60:40 rule - 1.2GB for Application server ,0.8GB for DB)

All the instances we have installed same . Now we are planing to upgrade extended memory 8GB to 32GB (approx 4times of previous memory)

Now my concern is if i increase extended memory 8GB to 32GB , how it will effect to SAP applications.

Should i go and change instance profile parameters ?

Which profile parameters i should change ?

And what is the memory caluculation proportionality rate for my previous and upgrade memory?

I should change all the 4 components ?

Is there any problem if i change wrong parametrs ?

Please suggest .
