http://www.unix.com – I am neither a DBA nor an AIX spcialist. We are running Oralce 11G on P5, AIX5.3. Per Oracle reports we are using 16 CPUs and 8 cores. However when I am looking at nmon report I find the cpu utilization is not load balanced. Code: CPU_SUMM User% Sys% Wait% Idle% xxx001 74.2 23.6 1.0 1.3 xxx002 71.1 10.1 &nb (HowTos)
