/usr/sam/lbin/getmem

Hi

I have many boxes with 11.0 and 11.11. I am trying /usr/sam/lbin/getmem command to get the physical memory. For non root users it gives nothing and for root users it gives wrong answer. I observed that this command is giving right answer in a B class workstation where memory is less than 512 MB. Anyone knows about this command? Why getmem misleading me? Is it a known issue?

TIA
Shahul

take a look at KBRC00010402
getmem doesn't report more the 512mb RAM
dmesg | grep P
or consider using glance ?

it is an obsolete command

Shahul,

I use the following script for memory reporting:

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

Pete your suggestion needs to read KMEM which is something users cannot do. it puts the problem back to
glance -m

Hi,
You can use this:

#/usr/sbin/dmesg |grep -i Physical
look for the output line beginning:
Physical: xxx Kbytes
Divide it by 1024 to the value in MBs.

Thanks.
