swapinfo -tam

Attaching a script to display ram deployment. It requires cstm be installed.

Rich,

Not being exactly sure what you mean by configuration, I'll offer this little script that gives you the size of RAM:

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

Hi Rich,

Check the faqs on Merijn's/Procura's page.

#
How much memory do I have

a5:/ 112 # echo "selclass qualifier memory;info;wait;infolog" | cstm | grep 'Total Configured'
Total Configured Memory : 2048 MB
a5:/ 113 # echo 'memory_installed_in_machine/D' | adb -k /stand/vmunix /dev/mem | perl -nle'/(\d+)/&&print$1*4,"k"'
2097152k
a5:/ 114 # grep Physical /var/adm/syslog/syslog.log
Aug 25 08:01:07 a5 vmunix: Physical: 2097152 Kbytes, lockable: 1562360 Kbytes, available: 1801856 Kbytes
a5:/ 115 #

Best regards,
Robert-Jan

grep -i memory /var/adm/syslog/syslog.log..

and also SysInfo utility is a good tool...

Or with adb...
