So from the prtconf output you have about 24GB memory total in the machine. What other information were you looking to get from the machine?

The below script will show you from smallest to largest the memory usage of each process:

The following shell script prints the memory usage of each process, sorted by ascending memory usage.

Code:

#!/bin/sh

/usr/bin/printf "%-6s %-9s %s\n" "PID" "Total" "Command"
/usr/bin/printf "%-6s %-9s %s\n" "---" "-----" "-------"

for PID in `/usr/bin/ps -e | /usr/bin/awk '$1 ~ /[0-9]+/ { print $1 }'`
do
   CMD=`/usr/bin/ps -o comm -p $PID | /usr/bin/tail -1`
   # Avoid "pmap: cannot examine 0: system process"-type errors
   # by redirecting STDERR to /dev/null
   TOTAL=`/usr/bin/pmap $PID 2>/dev/null | /usr/bin/tail -1 | \
/usr/bin/awk '{ print $2 }'`
   [ -n "$TOTAL" ] && /usr/bin/printf "%-6s %-9s %s\n" "$PID" "$TOTAL" "$CMD"
done | /usr/bin/sort -n -k2

swapoff

SWAPON(8)						     Linux Programmer's Manual							 SWAPON(8)

NAME

       swapon, swapoff - enable/disable devices and files for paging and swapping

SYNOPSIS

       /sbin/swapon [-h -V]
       /sbin/swapon -a [-v] [-e]
       /sbin/swapon [-v] [-p priority]	specialfile ...
       /sbin/swapon [-s]
       /sbin/swapoff [-h -V]
       /sbin/swapoff -a
       /sbin/swapoff specialfile ...

DESCRIPTION

       Swapon  is used to specify devices on which paging and swapping are to take place.  Calls to swapon normally occur in the system multi-user
       initialization file /etc/rc making all swap devices available, so that the paging and  swapping	activity  is  interleaved  across  several
       devices and files.

       Normally, the first form is used:

       -h     Provide help

       -V     Display version

       -s     Display swap usage summary by device. Equivalent to "cat /proc/swaps".  Not available before Linux 2.1.25.

       -a     All  devices marked as ``swap'' swap devices in /etc/fstab are made available. Devices that are already running as swap are silently
	      skipped.

       -e     When -a is used with swapon, -e makes swapon silently skip devices that do not exist.

       -p priority
	      Specify priority for swapon.  This option is only available if swapon was compiled under and is used under a 1.3.2 or later  kernel.
	      priority	is a value between 0 and 32767. See swapon(2) for a full description of swap priorities. Add pri=value to the option field
	      of /etc/fstab for use with swapon -a.

       Swapoff disables swapping on the specified devices and files.  When the -a flag is given, swapping is disabled on all  known  swap  devices
       and files (as found in /proc/swaps or /etc/fstab).

NOTE

       You should not use swapon on a file with holes.	Swap over NFS may not work.

FILES

HISTORY

       The swapon command appeared in 4.0BSD.
