Re: gathering history v$ to predict system change
Check out the statspack viewer at http://www.statsviewer.narod.ru. I played with it a little and it gives you graphs of the performance data gathered by statspack. I plan to check it more thoroughly in the near future.

RE: gathering history v$ to predict system change
Zhu - You can use STATSPACK to gather the statistics into its tables and then query those tables directly. In the book ORACLE High-Performance Tuning with STATSPACK, Don Burleson describes how to do this in detail and provides many example queries. He advocates gathering STATSPACK statistics over a day or week, then reviewing them to identify the times your system is performing the most processing. Based on that, you can gather statistics for the peak times with shorter time intervals.

Re: gathering history v$ to predict system change
Why not issue queries against the statspack tables to get your info?
