the cpu right now is high because they are not-using bind variables. Which is being fixed. So I was ignoring CPU usage.
Ive read that article. I dont remember any CPU material in there. I just focused on LIOs and didnt realize I needed to monitor CPU. However, high LIOs will lead to high CPU right? So in order to tune, wouldnt I concentrate on lowering LIOs and as a result that will bring down CPUs. I take CPU as a consequence of something, but not as a means to an ends. or am I wrong here? > > From: "Cary Millsap" <[EMAIL PROTECTED]> > Date: 2003/12/23 Tue PM 01:59:32 EST > To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> > Subject: RE: does CPU usage matter when scaling? > > Ryan, > > Take a look at "Why you should focus on LIOs instead of PIOs" at > www.hotsos.com/e-library.
