Hi,

I was looking if lsof was useful for listing open files, and yes it is.

see thread:

James R Ferguson explains this well.

Hi,
Dmesg is showing old mesg.
Don't worry about the /home is full.It was full some time back.
to see memory
#cat /var/adm/syslog/syslog.log|grep Phy
#echo phys_mem_pages/D | adb /stand/vmunix /dev/kmem

Hi again,
the message in dmesg is probably old: once in the past /home was full. If your next question is how to get rid of this - hopefully old - message, I think the only answer is to reboot your computer.

Hi,

Try this little script:

HPUX=/stand/vmunix
MAJORREV=$(uname -r | cut -f2 -d .)
if [ $MAJORREV -ge "11.0" ]
then
MYSYMBOL="phys_mem_pages"
else
MYSYMBOL="physmem"
fi

MYMEM=$(echo "${MYSYMBOL}/D" | adb $HPUX /dev/kmem | grep "${MYSYMBOL}: *." | awk '{printf "%.0f MB\n",$2/256}')
echo $MYMEM

echo phys_mem_pages/D | adb64 /stand/vmunix /dev/mem

or

cat /var/adm/syslog/syslog.log|grep Phy

to find out the amount of RAM.

To list out open files use
you can use lsof ot you can use glance to find that

Thanks

the output of
echo phys_mem_pages/D | adb64 /stand/vmunix /dev/mem will be in memory pages

so multiply that with
X 4096

THanks
