Shiv,
here is a small script courtesy Stephan Farrely
-----------------------------------
#!/bin/ksh
# Find total memory claimed by system.
# With help of Stefan Farrely
count=0
for input in `UNIX95= ps -e -o vsz=Kbytes -o ruser -o pid,args=Command-Line | sort -rnk1 | grep -v Kbytes | awk '{print $1}'`
do
count=`expr $count + $input`
done
print "Total memory claimed : $count Kbytes \n"
----------------------

thanks

Shiv,

Depends on the OS version you are using.

For 10.x use:

# echo physmem/D | adb /stand/vmunix /dev/kmem

For 32-bit 11.x use:

# echo phys_mem_pages/D | adb /stand/vmunix /dev/kmem

For 64-bit 11.x multiply the output below with 4096 for total memory in bytes:

# echo phys_mem_pages/D | adb /stand/vmunix /dev/kmem

with SAM...

SAM -> Performance Monitors -> System Properties -> Memory

cheers!

Sorry correction multiply the output of each of the above commands with 4096 to get the total memory in bytes or simply use SAM.

hope it helps!!!

Hi Shiv,

To get the total physical memory on a system
grep -i physical grep -i physical /var/adm/syslog/OLDsyslog.log

or

Memory:

echo 'phys_mem_pages/D' |adb -k /stand/vmunix /dev/kmem

Multiply the above with 4 to get it in KB.

hi,

aside from pulling out the top of yr server ....

try this:

# dmesg|grep Physical
for total physical memory

if u r running make_tape_recovery, run print_manifest command for other hardware, software and kernel info.

or use sam -> Performance Monitor -> System Properties -> Memory tab


regards.

[Muthukumar_5]

You can get it by,

1> sam -> performance monitor -> system properties -> memory tab

2> dmesg | grep 'Phy'

3> If ignite-ux installed,
print_manifest

4> If o/s version is 11.23 then,
machinfo

hth.

Hi Shiv,

You can use dmesg or glance plus or stm all will give you system memory.

Cheers!!!

Shiv

easiest would be to fire up glance
or
dmesg | grep -i physical

and the like

Hi Shiv,

The most common procedure for the same are following three.

#dmesg |grep Physical

to know total memory installed in the ststem.
For detaled information regarding various physical modules installed in the system try.

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

HTH,
Devender

Hi Shive

1. #dmesg |grep physical is one of way of knowing physical memory in system

2. #top can also give you an idea on system memory
