how to know about memory available?

[bossuyt]

hi folks,

with which command can i know how much RAM is on the computer (ram, not swap), without using dmesg.

thanks

If you have DIAGS installed, can use the stm utility. top will also show.

Forgot about SAM as well. Go into System Properties.

[Rita C Workman]

When your system comes up it display the physical memory.
You can enter dmesg.
You can also check this via SAM/Performance Monitors/System Properties and then look under the Memory tab.....it's all there!

You can always look in /var/adm/syslog/syslog.log:
cat syslog.log |grep Physical:
vmunix: Physical: 524288 Kbytes, lockable: 441956 Kb
ytes, available: 472492 Kbytes

Hi,

look at this thread:

Andy Monks has attached a little C program for this issue.

Or you could use adb if you want to get the value into a shell variable:-

10.20
let MEM=$(echo 'physmem/D'| adb /stand/vmunix /dev/kmem | tail -1 | awk '{print $2}')
let MEM="(MEM+128)/256"

11.00
let MEM=$(echo 'phys_mem_pages/D'| adb /stand/vmunix /dev/kmem | tail -1 | awk '{print $2}')
let MEM="(MEM+128)/256"

In both cases, ${MEM} is in megabytes.

Use echo "mem_ptr/D"| adb /stand/vmunix
/dev/mem (gives in number of bytes).
Or

cat /var/adm/syslog/syslog.log|grep Phy*
This will show you the Physical; Lockable and Available memory in Kbytes

Instead of activating SAM you can also use the tool on command line. Type /usr/sam/lbin/getmem as root. It will display the physical RAM installed in MB.
