Hi,
I've just setup a test-database (oracle10g standard) and am about to do some tests.
I will do some benchmarks, and here I need your help to advice on my spfile settings.
The testdb is running on a Solaris 10 x86.
No other applications beside Oracle is running, and it is equiped with:
2.8 GHz Xeon CPU and 2GB Memory.
I want to use the maximum resources (cpu/memory) for this Oracle instance.
Please advice,
Thank you!

You are probably fine, depends on what you are trying to do though. Your sga target might be a bit on the high side, might want to reduce it by 256MB and increase pga target by 256MB.
But many params, especially in the newer versions and for a testing database, are fine with the defaults, and it is just a matter of you tweaking them as the need arises.
Your workarea size policy is set to auto right?
And undo management also auto?
I like to pre page, and lock, my sga.
And if you are just downloading and testing, almost might as well go with 10gR2 instead of 10gR1.
