Hello,
Is it possible to run a certain process on a certain processor, in other words, can we isolate a processor (or a set of processors) and run certain applications on this set?
Thanks alot
Aly
How come on Solaris 8 that the sar command indicates that the %wio is very high (90%) and so does the mpstat as well:
09:14:52 %usr %sys %wio %idle
09:14:54 9 5 86 0
09:14:56 7 5 88 0
09:14:58 14 8 78 0
09:15:00...
What kind of tunning are we talking about! we have a direct quiries and Business objects hitting that DB beside other DBs from other servers.
I guess there is no much space to tune anyway, is there?
Hi, thanks for your quick response, here under are the results of uptime, sar -q, mpstat

Hi,
Running Solaris 8 on SUN E12K (4*1050 CPU, 16 GB RAM) with Oracle9 DB
CPU%: 99% Utilization
RAM%: 50% and 0 sr
I believe that the memory is overwhelming the CPU as it was not the case in the previous machine (E10K, 10*450 CPU, 8 GB RAM)
1. Is there a ratio between the cpu and memory...
Hi,
Thank you all for your help, I tried "topas" and it gave me accurate data.
I found as well a tool called "nmon" which can be downloaded from IBM
http://www-1.ibm.com/servers/esdd/articles/nmon_analyser/#4
which gives a detailed infor as well.
cheers, Aly
Hi,
Using the "ps aux" command does not reflect the actual resources consumed by a process, do I use wrong switches or is there any other commands to use?
ps aux sample:
USER PID %CPU %MEM SZ RSS TTY STAT STIME TIME COMMAND
root 774 46.4 0.0 12 8108 - A...
IBM PSERIES 660 MODEL 6H1
2x750 (2 ways) MHz CPU, 2GB RAM
I'm running my own scripts to gather and get a hourly average, the output is something like that:
(Hour)(RAM utilized %) (scan rate) (free RAM)

1. scan rate is the number of mameory scaned pages to be swaped due to in-sufficient memory (high scan rate means high memory demanding leading to the fact of lake in memory resources)
2. I made a dummy loop script that consumes all the CPU resources (sar gives 0 Idle) and yet I still see the...
Hi,
I have two questions on AIX 4.3.3:
1. During the backup I get a very high memory scan rate (reaches 600) whether in normal cases its less than 40. what am I may doing wrong?
2. To monitor the resources conumed by each process I use "ps aux", however it gave wrong answers...
