Am working on small program that used to calculate the memory usage of AIX servers. Am using svmon -G command to get the memory usage. For example, consider the following output.
Code:
$ svmon -G
size inuse free pin virtual mmode
memory 1957888 670177 1287711 411476 512709 Ded
pg space 131072 2929
work pers clnt other
pin 350964 0 0 60512
in use 512709 0 157468
PageSize PoolSize inuse pgsp pin virtual
s 4 KB - 269713 2929 85684 112245
m 64 KB - 25029 0 20362 25029
$
Am using "in use" value at the 6-th line number as memory usage. It gives 26 % as a memory usage. Also am using /bin/ps -eo comm,pmem,args to get the all the process memory usage to confirm with previous calculation.But value calculated by both methods does not match.
Please advise.

edit by bakunin: my first advice is to use CODE-tags. Its the button misleadingly labeled "CODE" (in case you can't find it).
Hi All,
I have a question, can you guys please help me by giving your valuable suggestons:
I am using AIX 5L, running oracle 7 version. I need to increase the oracle memory to 40 MB more. Currently Oracle occupies 260M. I wanted to know whether I can increase the memory without any problem.... (1 Reply)

Hi, i have 2 identical web servers using AIX. I use nmon analyser to check their performance.
The server A exceeds 20% memory usage for system, 5% for cache and the rest 75% for processes. While, it uses 4% of Paging Space.
The server B exceeds 20% for system, 45% for cache and 35% for processes.... (24 Replies)

gpioctl
GPIOCTL(1) BSD General Commands Manual GPIOCTL(1)NAME
gpioctl -- GPIO control utility
SYNOPSIS
gpioctl -l [-f ctldev] [-v]
gpioctl -t [-f ctldev] pin
gpioctl -c [-f ctldev] pin flag [flag ...]
gpioctl [-f ctldev] pin [0|1]
DESCRIPTION
The gpioctl utility could be used to manage GPIO pins from userland and list available pins.
The options are as follows:
-c pin flag [flag ...]
Configure pin by setting provided flags. The following flags are currently defined:
IN Input pin
OUT Output pin
OD Open drain pin
PP Push pull pin
TS Tristate pin
PU Pull-up pin
PD Pull-down pin
II Inverted input pin
IO Inverted output pin
-f ctldev GPIO controller device to use If not specified, defaults to /dev/gpioc0
-l list available pins
-t pin toggle value of provided pin number
-v be verbose: for each listed pin print current configuration
EXAMPLES
o List pins available on GPIO controller defined by device /dev/gpioc0
gpioctl -f /dev/gpioc0 -l
o Set the value of pin 12 to 1
gpioctl -f /dev/gpioc0 12 1
o Configure pin 12 to be input pin
gpioctl -f /dev/gpioc0 -c 12 IN
SEE ALSO gpio(4), gpioiic(4), gpioled(4)HISTORY
The gpioctl utility appeared in FreeBSD 9.0.
