I've got this voice application running on AIX. ever so often you just have to restart that application since everything comes to almost a halt. I did run just the basic sar. The only thing i noticed was the wait i/o was 97% and pct idle was 3%. How do i determine what the causes are? This may be a seperate question, but how do i set up sar to give the best info plus i think it is supposed to give reports.
