Physical Memory in HP-UX

Nicky Power — Thu, 07 Dec 2006 06:56:04 GMT

What is the command to use when you need to find the physical memory of a HP-UX box...

A support company ran a command
ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 786432
stack(kbytes) 8192
memory(kbytes) 370064
coredump(blocks) unlimited
nofiles(descriptors) 4096
vmemory(kbytes) 4194304

This provides certain details such as above. it is recommended that we increase the memory setting... but before I do this I need to know how much we have...

If I was to increase the memory setting... how can this be done?

Thanking you,

Niccky,
a few commands are possible:
dmesg | grep
Using SAM -> Performance Monitor -> System Properties -> Memory

I found this excellent utility to let you know everything about your memory. I have attached it...I use it all the time. Here is a sample of the output from one of my systems.

HTH,
S.

Memory Stat total used avail %used
physical 6142.0 4648.3 1493.7 76%
active virtual 2311.2 2143.4 167.8 93%
active real 2102.9 1975.4 127.5 94%
memory swap 6142.0 3223.8 2918.2 52%
device swap 8192.0 2526.3 5665.7 31%

Actually, the one that coolmar attached should really be compiles for your system,

Here's a c program (just compile it with the native HP-UX compiler) called memdetail:

# memdetail
Memory Stat total used avail %used
physical 14240.0 12606.9 1633.1 89%
active virtual 15227.2 4860.9 10366.3 32%
active real 10316.3 3063.5 7252.8 30%
memory swap 11139.4 1788.3 9351.1 16%
device swap 26528.0 14599.9 11928.1 55%

Hi,
you cam use swapinfo. But maybe you can also use Glance to get this information.

run glance and choose "m" for memory report.

Another (for HP-UX 11.x):

echo phys_mem_pages/D | adb -k /stand/vmunix /dev/mem | tail -1 | awk '{printf("%.2f MB\n",$2*.004096)}'

Answer's from HP professional:
echo phys_mem_pages/D | adb -k /stand/vmunix /dev/mem

Ordinary people:
dmesg |grep Physical
