I think the wide range of answers as to what this output means is a good indication that IBM would do well to develop a more concise tool for reviewing resource utilization. As for my opinion I would start with 'vmtune' and then look at 'iostat'. Good Luck

I am runnning AIX 4.3.2 on a H50. TSM is the only application running on the server. When I run vmstat I get the following... kthr memory page faults cpu ----- ----------- ------------------------ ------------ ----------- r b avm fre re pi po fr sr cy in sy cs us sy id wa 0 0 136233 202 0 3 2 99 210 0 52 240 66 17 30 16 37 1 3 136234 342 0 38 11 3727 4204 0 1322 6136 4665 12 11 3 74 2 3 136236 160 0 44 12 3728 5326 0 1324 5844 4644 10 11 2 76 1 3 136237 295 0 17 19 4113 5725 0 1305 7174 5091 13 10 3 74 0 3 136237 629 0 19 9 4240 7442 0 1316 7200 5082 14 13 5 68 Does this look normal to anyone? From my limited understanding of vmstat it looks like: CPU utilization is maxed out I have blocked processes (the b column) The scan rate (sr) column is very high. The server has 1Gig of memory. I'm really not sure how to tell how much is allocated to the OS and how much is allocated to TSM. Does anyone have any ideas or pointers is tuning memory for AIX? Do I need a memory upgrade? I started checking this because my server response is horrible. Thanks. Denis
