Operating Systems AIX topas - computational memory 95% : Any Impact? Post 302492924 by zxmaus on Wednesday 2nd of February 2011 12:12:43 AM

I am glad it helped.

I can see that you are currently not paging what is good - and no scan to free what is good as well - but 22 GB avm (computational memory) when you only have 22 GB is not that good as every new connection / DB query will probably cause paging.

From your vmstat output ...
Quote:
15661 paging space page ins
102513 paging space page outs
Each of these will definitely cause your system to slow down - so you should try to avoid them. Same recommendations I almost always give: try to mount with noatime option and switch Oracle to SETALL - ideally this frees up some computational memory.

NAME
substrate - Grow crystal-like lines on a computational substrate SYNOPSIS
substrate [-display host:display.screen] [-foreground color] [-background color] [-wireframe] [-max-cycles cyclecount] [-growth-delay delayms] [-initial-cracks numinitial] [-max-cracks nummax] [-sand-grains numgrains] [-circle-percent circlepercent] [-fps] DESCRIPTION
Lines like crystals grow on a computational substrate. A simple perpendicular growth rule creates intricate city-like structures. Option- ally, cracks may also be circular, producing a cityscape more familiar to places for which city planning is a distant, theoretical concern. Ported from the code by j.tarbell at http://complexification.net OPTIONS
substrate accepts the following options: -wireframe (Default: False) Don't draw sand-painting colored effects, only make a wireframe. -max-cycles cyclecount (Default: 10000) Maximum number of growth cycles before restarting. The higher this is, the more complex the art. -growth-delay delayms (Default: 18000) Delay in ms between growth cycles. More delay, slower (but smoother and less CPU intensive) art. -initial-cracks numinitial (Default: 3) Initial number of cracks in the substrate -max-cracks nummax (Default: 100) Maximum number of cracks in the substrate at a single time -sand-grains numgrains (Default: 64) Number of sand grains dropped during coloring. More grains cause a denser colour but use more cpu power. -circle-percent circlepercent (Default: 0) The percentage of the cracks will be circular. -fps Display the current frame rate and CPU load. ENVIRONMENT
DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. SEE ALSO
