Use SAM -> Performance Monitors -> System Properties
Tab to memory and view values.

Can also use swapinfo -tma

dmesg | grep Phy will give the amount of Phtsical Memory on the system as well.

Checking dmesg is good as long as the message buffer hasn't wrapped.

Another way, is via a small program which I've attached. Just compile and run

make phys_mem.c
./phys_mem

This is just a clarification on some of the other messages. dmesg is probably the best way to see your total physical memory. It will also show you lockable memory. However, info in dmesg is just coming from the startup sequence and can get overwritten by other errors. If this occurs than you can grab it out of the kernel with adb debuggers. See Knowledge Base Document KBRC00001146.

Finally, someone mentioned that swapinfo -tma will show you this. This is FALSE. The MEMORY line in swapinfo is the amount of memory that is being used for pseudo swap. This can be as much as 75% of your total physical memory. This is not hard to comfirm. Just compare the output of swapinfo with dmesg.

Yet one more way is to use the Support Tools Manager. There are character and GUI versions. I prefer the GUI.
Run xstm for GUI or mstm for character. Highlight the Memory icon or cursor to the Memory line. Then go to Tools > Information > Run to get a report. It gives you more information on the physical memory in your system. Shows what size memory module is in what slot. It helps to know if you have any slots available before you buy additional memory.

One further way:

Check /var/adm/syslog/syslog.log, the same message that dmesg can contain
is 'permanently' written to syslog on boot. Plus, by default non-root users can
read syslog too.

Hi,
Try any of the following.

1. #dmesg |grep -i phy (may not work if the message buffer is filled up with some other messages)

2. # echo "mem_ptr/D"| adb /stand/vmunix
/dev/mem (gives in number of bytes)
3. SAM --> Performance Monitors --> System Properties ---> Memory

You can also use /usr/sam/lbin/getmem
which gives you the RAM im Megabyte. As this is a commandline tool you can use it very easy in your own scripts.

Just one command; /usr/sam/lbin/getmem (results are in Megabytes)
