The command for memory information is....?

I've forgotten the command to find out my memory information on my Nclass, I thought it was MEMMAP or somthing of the sort. PLEASE HELP!

What kind of memory info:

swap:

swapinfo -tam

page, active, virtual

vmstat

shared mem:

ipcs -mo

Or use glance to get all of this in one place.

HTH.

You can use adb....or this handy script called hpmem:

echo "phys_mem_pages/D" | adb /stand/vmunix /dev/kmem | grep phys | tail -1 | awk '{printf "%.0f MB\n",$2/256}'

i can't test that it is correct but it looks ok! :-)

As long as you have diagnostics loaded on your system (which you should) this little one liner, will map what's in the memory slots.

# echo "selclass qualifier memory;info;wait;infolog" | cstm

Hi

I'd also add that if you want to find the amount of free memory on your system you can use the following:
# vmstat 1 2 | tail -1 | awk '{printf "%d %s\n", ($5*4)/1024, "MB" }'

This will give you the amount of free memory in MB. Alternatively you can use glance if it's installed ('m' option).

Cheers
