How to calculate SAP/Oracle Performance parameter

Dear All,

Recently i stuck with SAP performance issues So maximum time its related to Database so Here i have oracle and i am sharing a report and script through which you can find out the optimum Oracle database Parameters :

Steps:
1) Log-in to SAP system
2) Go to SA38/Se38
3) Give report name RSORADJV
4) Paste this script in provide window ( Script is for 10.2.0.2 only)
