I've said this before in another thread: Tune the application before you
tune the system. Fixing a broken or misconfigured or badly designed
application can improve performance a great deal. On a well tuned and
properly configured system, you may perhaps get 10% performance
improvement.

So, get with your DBAs and start tuning Oracle's performance _first_.
They'll suggest changes to improve Solaris. If you don't have any DBA's
that can do this, hire a consultant. Those that know what they're doing
are worth it, especially since you're stuck on an old version of Solaris
which is soon to be end-of-lifed (but you knew that, right?).
