Memory — Wed, 20 Jul 2011 09:34:59 GMT

MY swap utilization is very high ., i just need to find the top memory utilization processes.

am using below command to retrieve , but due to shell problm am getting error UNIX95 not found , pls suggest.

my command : UNIX95=1 ps -eo pid,ppid,vsz,args | sort -nr | head -10

Hi

Try below

UNIX95= ps -eo sz,comm,args | sed 1d | sort -rn | awk '{size=$1/1024; printf("%dMb %s\n", size,$2);}'

or

UNIX95= ps -eo vsz,comm,args | sed 1d | sort -rn | more

Thanks

Hello Naj , Thanks for you reply..

still am getting the error : UNIX95= not uctvp628%

nexec -e UNIX95= ps -eo vsz,comm,args | sed 1d | sort -rn | more

/sbin/sh: UNIX95=: not found. uctvp628%

uctvp628% nexec -e UNIX95= ps -eo sz,comm,args | sed 1d | sort -rn | awk '{size=$1/1024; printf("%dMb %s\n", size,$2);}'

/sbin/sh: UNIX95=: not found.

am not connecting via putty, we have separate tool to connect the servers with out giving any username / password. suspect the issue is with some terminal issue , pls suggest

Try this $ UNIX95= ps -e -o "user,vsz,pid,ppid,args" | awk 'NR>1' | sort -rnk2 | head -10

Or if you can check top output also.

When using the UNIX95 syntax, it is important to remember that there is a space between the equal sign (=) and the ps command. I think that may be why you were getting errors when you tried the command Naj gave you.

Re: To find highly memory utilized processes

Hi,

Sorry being late to reply,

I'd tested all the command above and was working fine from my end.

I do not sure what exactly problem that you have facing but you can try execute below command

alias ps="UNIX95= /usr/bin/ps"

Now, all your ps commands will have the extra options available.

Next step is try execute ps command without UNIX95

root@twst2a / # ps -e -o "user,vsz,pid,ppid,args" | awk 'NR>1' | sort -rnk2 | head -10
root      503800 16579 15163 /opt/OV/lbin/perf/coda
root       48540 11899     1 /opt/wbem/lbin/cimprovagt 3 9 SFMProviderModule
root       33488 16073     1 /opt/perf/bin/midaemon
root       19384 16054     1 /opt/perf/bin/scopeux
root       18664 25255     1 /opt/omni/lbin/crs
root       16944 15907 12997 sort -n

Good luck!

Thanks

That isn't going to work in HP-UX. The '-o' argument applies only to XPG4 (UNIX95). You have given it the appearance of working by setting the environmental variable in your alias.

Don't think, either, about setting UNIX95 in your login profile. There may be side effects with other commands of which you are not aware and which will lead you into trouble. Setting the variable locallly for the duration of the command line is what the variable declaration does when followed by whitespace and a command. This is safe.

AS Naj suggested i have tried by seting alias.

still i could'nt retrive the processes, any other method to retrive the high memory / swap utilized processes

uctvp628% nexec -e alias ps="UNIX95= /usr/bin/ps"
uctvp628% nexec -e ps -e -o "user,vsz,pid,ppid,args" | awk 'NR>1' | sort -rnk2 | head -10
ps: illegal option -- o
usage: ps [-edaxzflP] [-u ulist] [-g glist] [-p plist] [-t tlist] [-R prmgroup] [-Z psetidlist]

try these.

ps auwx |sort –r +2 | head –x (where x =5, 10, 15, etc..) à this is to see top CPU using processes
ps auwx |sort –r +3 | head –x (where x =5, 10, 15, etc..) à this is to see top Memory using processes

First try using the provided ps(1) commands without this nexec.

swapinfo -tam will give you the big picture.

You can't logon at all just to try the experiment?

Shalom,

Are you logged in on console?

Doesn't matter whether you are using putty or not. We need to see command output to assist.

Setting UNIX95 in the root command profile will cause among other bad things, checksums on patches to fail. You will not be able to create depots. Only set UNIX95 when you need to set UNIX95

another alternative to use glance OR full-path /opt/perf/bin/glance if you have, it is talented tool, also Steven 's mem.mon script is great.

but I suspect your connection issue what kind of connection you try ?
