This is another SYSTEM, it is IBM P 550 with 6 Processors and with Memory 96GB / 32GB Paging Space. 1000 users connecting concurrently to the Oracle Database
This is one of the best topics and most useful one as many companies buy AIX machines solely for Oracle Database.
The machine is still running slow. How can one trace and fine tune ?

hi,
how can i diplay:
- the ammount RAM used /free
- ammount of ram used from a pid or prozess
we have the problem, that malloc is returing a NULL pointer errno = 12 ( not enough space).
but i think there is still ram free.

good morning
what is the better solution to examen a P570 ?
because i use topas and nmon, and the results are totally different !!!
with nmon, i have 80% free cpu, and with nmon, i have 90% of used cpu !!!!!!
i take a shot with an intervall of 10s during 10 mn.

Hi Guys,
Need you help in one point!
I am working on one shell script which takes following steps :

2. Exporting that result to Xls file
3. Mailing that file to my own mail ID
Now, I want to give a threshold limit to one of the column... (0 Replies)

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
