Thanks Dennis,
I have periodic (10 mins) snapshots taken of following views ...
1. gv$session
2. gv$sesstat
3. gv$transaction
4. gv$sess_io
5. gv$sysstat
Now, I really _can't_ use Statspack, because it tells me overall score. I need to compute the load put on system by a set list of users ... it is kind of computation of possible charge back.
So, I have the underlying system stats. but I am having tough time to put them in perspective for management types. I'd like to show them %CPU usage, %IO load, %Memory being used ...
any ideas?
Raj

I'll second Jared's idea. Don Burleson in his book Oracle9i
High-Performance Tuning with STATSPACK makes a strong point that looking at
system load must start with the underlying system. Any look at Oracle
performance must begin with an understanding of what the system load was at
that time. As Jared points out, the three components are CPU, I/O, and
memory. For example, you may find that one of these target users is the high
CPU consumer from an Oracle perspective at a point in time. Now, if you
discovered the system CPUs weren't being taxed at that time your conclusions
might be different than if you discovered the system CPUs were pegged at
100% at that time.

Load on a system is in general comprised of three components:
CPU, memory and IO.
If you have something in place to track those on a per user
basis, then you're doing well. You might consider also tracking
other users, so that you have a basis for comparison.
