From the nmon, what is the PageSpace %used ?
This shows similar output to
Code:
lsps -a

and just how much percent of available paging space is being used. What does lsps -a show on your system?

Also I see Page Faults value are high. Is this mean the system is having memory constraints?
No. A Page Fault just says, that the requested data is currently not in memory and has to be read from disk. AIX is caching files in RAM, but if data is requested and not already in the cache, it has to be read from where it resides. So something very normal and nothing to worry about.

Looking at the vmstat, there seems to be no problem with your system at the time of the vmstat output taken. If you had actually memory problems, there would be non-zero values showing up in the columns for pi and po, which is reading from and writing to Paging Space. Though this is just a short snapshot. To see if there is paging eventually you might have to monitor it over a longer time, since there is also some
Code:
              901109 paging space I/Os blocked with no psbuf


Code:
               866061 external pager filesystem I/Os blocked with no fsbuf

This maybe no biggie but could be tried to avoid by increasing j2_dynamicBufferPreallocation - if it doesn't work you might also consider to increase j2_nBufferPerPagerDevice. For values, behaviour (dynamic) etc. you might want to have a look into the man page of ioo for those 2 parameters.


By the way - for a more tidier view of the columns of vmstat, you can use the -w switch so values will be indented accordingly to the heading.

NAME
ttk_image - Define an element based on an image SYNOPSIS
ttk::style element create name image imageSpec ?options? _________________________________________________________________ DESCRIPTION
The image element factory creates a new element in the current theme whose visual appearance is determined by Tk images. imageSpec is a list of one or more elements. The first element is the default image name. The rest of the list is a sequence of statespec / value pairs specifying other images to use when the element is in a particular state or combination of states. OPTIONS
Valid options are: -border padding padding is a list of up to four integers, specifying the left, top, right, and bottom borders, respectively. See IMAGE STRETCHING, below. -height height Specifies a minimum height for the element. If less than zero, the base image's height is used as a default. -padding padding Specifies the element's interior padding. Defaults to -border if not specified. -sticky spec Specifies how the image is placed within the final parcel. spec contains zero or more characters "n", "s", "w", or "e". -width width Specifies a minimum width for the element. If less than zero, the base image's width is used as a default. IMAGE STRETCHING
If the element's allocated parcel is larger than the image, the image will be placed in the parcel based on the -sticky option. If the image needs to stretch horizontally (i.e., -sticky ew) or vertically (-sticky ns), subregions of the image are replicated to fill the par- cel based on the -border option. The -border divides the image into 9 regions: four fixed corners, top and left edges (which may be tiled horizontally), left and right edges (which may be tiled vertically), and the central area (which may be tiled in both directions). EXAMPLE
set img1 [image create photo -file button.png] set img2 [image create photo -file button-pressed.png] set img3 [image create photo -file button-active.png] style element create Button.button image [list $img1 pressed $img2 active $img3] -border {2 4} -sticky we SEE ALSO
