Memory on 11x boxes

[Prasad Karpur]

What is the command to check the memory on a 11.x box?

[RAC_1]

grep -i physical /var/adm/syslog/syslog.log

echo "memory_installed_in_machine/D"|adb -k /stand/vmunix /dev/kmem

[Michael Tully · Accepted solution]

There are several:

# dmesg | grep -i phys
# echo "selclass qualifier memory;info;wait;infolog" | cstm
# grep -i phys /var/adm/syslog/syslog.log

Hi,

Check as in test or how much ?

How much
# echo "selclass qualifier memory;info;wait;infolog" | cstm | grep 'Total Configured'

Test fire up stm
# xstm

There are several:

1. adb:

echo "phys_mem_pages/D" | adb64 -k /stand/vmunix /dev/kmem \
| tail -1 | awk '{print $2/256000 " GB"}'

2. # dmesg | grep -i phys
physical page size = 4096 bytes, logical page size = 4096 bytes
Physical: 12386304 Kbytes, lockable: 9504664 Kbytes, available: 10918860 Kbytes

3. Glance
hit "m" for memory

4. # /usr/contrib/Q4/bin/kmeminfo

shows memory in pages (4096 bytes).

there are probably more ways!

You can also find the memory information from SAM -> performance monitors -> system properties. Also, look at cstm, stm and mstm options for more detailed memory slot information.

All good suggestions given above. However, be careful with the easiest solutions of examining "dmesg" or "syslog". "dmesg" buffer may have rolled off so the memory info is not available, and "syslog.log" may have been truncated and also not have the info. So I would trust the other methods more even though they're slightly more "complicated".
