Viewing amount of RAM

Ransom T. Scott — Tue, 15 Aug 2000 12:31:06 GMT

I once had a command that would allow me to see how much RAM our HP9000, but have since lost it. Can anyone help me with this.

Use this script;

#!/bin/ksh
if [ `uname -r` = "B.11.00" ]
then
echo "phys_mem_pages/D" | adb /stand/vmunix /dev/kmem|grep phys|tail -1|awk '{print $2/256 " MB"}'
else
echo "physmem/D" | adb /stand/vmunix /dev/kmem|grep phys|tail -1|awk '{print "Memory size = " $2 / 256 " Megabytes"}'
fi

or use; /usr/sam/lbin/getmem

The /usr/sbin/dmesg command shows amount of phisical memory in KB.

Ransom,
You can use SAM (if you like SAM)
Performance Monitors -> System Property -> Memory

Or run the information tool from STM on the memory

there is also the Memory Information in the dmesg output. someting like:
Memory Information:
physical page size = 4096 bytes, logical page size = 4096 bytes
Physical: 524288 Kbytes, lockable: 382468 Kbytes, available: 443616 Kbytes

Hi,
dmesg will show you the Physical memory installed on th e server, or vi /var/adm/syslog/syslog.log

Or you can just compile up the small program attached.

Many commands will show you the RAM on a system. "dmesg | grep -i phy" will show the physical memory. SAM will get the info and more (Performance Monitors -> System Properties), top can show you and how it is being used, etc.

STM from diagnostics could be an option as well.

All of the answers are correct. I like the approach Antoanetta posted. stm or xstm not only tells you how much memory you have, it tells you what memory modules are in what memory slots.
If a command tells you there is a GB of memory, is it two 512MB modules or four 256MB modules? If you want to add memory it's good to know if you have open slots to put it in.
