We were receiving out of process memory errors - unable to allocate .. bytes of memory for PGA
Could you provide the exact error code and message (ORA- ...)?

vmstat - sr was increasing constantly and used oracle EM to monitor memory usage
The scan rate is not enough, check if si/so have values different than 0
(or if pi/po have high values) with vmstat -S.

I can check within Oracle by checking v$pgastat , v$process etc
Could you post the output from:

Based on the average RSS size I am multuiplying it by total processes to compute total memory usage
of these processes, is this the right way of computing the memory usage of these processes?
Just sum the RSS values of all those processes:

Hi all,
Without oracle tunning I understand that oracle processes always run on a single CPU at a time (the prstat output always show 1 CPU number) even on multi-processor hardware.
Is it correct?

Hello,
I'm looking for a command or script that could permit me to know what is memory usage group by HP-UX kernel, oracle processes and other users (specific software).
A command like 'top' but for all processes and not only for 12 max could be very useful
Thanks in advance (4 Replies)

Hi,
I'm running a multi-process software system on a Solaris 8 machine. When I monitor the memory usage, I see that the free memory is dropping rapidly, but I can't detect a process that uses this memory.
I'm using "top" to get the free memory and the memory usage of processes.
Thanks. (3 Replies)
Hi All,
We have a server with Solaris 10 installed. The total memory of the server is 64GB. In order to check the memory info of the server I use "top" utility that gives me total and free memory in real-time.
I have also installed a Sun container (non-global zone) on top of parent operating... (4 Replies)

shell-quote
SHELL-QUOTE(1) User Contributed Perl Documentation SHELL-QUOTE(1)NAME
shell-quote - quote arguments for safe use, unmodified in a shell command
SYNOPSIS
shell-quote [switch]... arg...
DESCRIPTION
shell-quote lets you pass arbitrary strings through the shell so that they won't be changed by the shell. This lets you process commands
or files with embedded white space or shell globbing characters safely. Here are a few examples.
EXAMPLES
ssh preserving args
When running a remote command with ssh, ssh doesn't preserve the separate arguments it receives. It just joins them with spaces and
passes them to "$SHELL -c". This doesn't work as intended:
ssh host touch 'hi there' # fails
It creates 2 files, hi and there. Instead, do this:
cmd=`shell-quote touch 'hi there'`
ssh host "$cmd"
This gives you just 1 file, hi there.
process find output
It's not ordinarily possible to process an arbitrary list of files output by find with a shell script. Anything you put in $IFS to
split up the output could legitimately be in a file's name. Here's how you can do it using shell-quote:
eval set -- `find -type f -print0 | xargs -0 shell-quote --`
debug shell scripts
shell-quote is better than echo for debugging shell scripts.
debug() {
[ -z "$debug" ] || shell-quote "debug:" "$@"
}
With echo you can't tell the difference between "debug 'foo bar'" and "debug foo bar", but with shell-quote you can.
save a command for later
shell-quote can be used to build up a shell command to run later. Say you want the user to be able to give you switches for a command
you're going to run. If you don't want the switches to be re-evaluated by the shell (which is usually a good idea, else there are
things the user can't pass through), you can do something like this:
user_switches=
while [ $# != 0 ]
do
case x$1 in
x--pass-through)
[ $# -gt 1 ] || die "need an argument for $1"
user_switches="$user_switches "`shell-quote -- "$2"`
shift;;
# process other switches
esac
shift
done
# later
eval "shell-quote some-command $user_switches my args"
OPTIONS --debug
Turn debugging on.
--help
Show the usage message and die.
--version
Show the version number and exit.
