How can I find the base memory of my box

thanks in advance

If by base you mean physical memory than these first two will answer it.
1-go under SAM/Performance Monitors/System Properties and select the corresponding tab.
2-Or another way to get memory...run dmesg

Or for swap mem set up and used... run swapinfo -tm

Just a couple thoughts,

Hi,

If you mean 'How much memory does my system have?' then there are several methods:-

1) glance - if you have it 't' or 'm' screens
2) dmesg - providing it hasn't been overwritten gives you a 'Physical: nnnn Kbytes
3) STM tools allow interrogation of memory down to type and slot position.
4) echo 'phys_mem_pages/D'| adb /stand/vmunix /dev/kmem
will give you the number of 4Kbyte pages (on HP-UX 11) or:-
echo 'physmem/D'| adb /stand/vmunix /dev/kmem
will give you the number of 4Kbyte pages (on HP-UX 10.20

Pick one...

Regards,
John

Hi
Base memory , i thought was the on chip memory ,that is memory on the CPU.
Am I correct ?

Thanks and Regards

Base memory is the amount of memory installed in your system, just as in a PC.

To find out how much memory (cache) is on your CPU chips then you need to identify what type of server/cpu's you have. Or, use STM (xstm) it will tell you this info if you select a CPU then go to info report.

[Stefan Farrelly]

eg. on my little workstation I go into XSTM, select the CPU, then go to Tools -> Information -> Information Log and here is what it gives;

Product ID: CPU Module Type: 0
Hardware Model: 0x59d Software Model: 0x4
Hardware Revision: 0 Software Revision: 0
Hardware ID: 0 Software ID: 2009591309
Boot ID: 0x2 Software Option: 0x81
Hard Physical Address: 0xfffa0000 Soft Physical Address: 0
Slot Number: 8 Software Capability: 0x100000f0
PDC Firmware Revision: 6.1 IODC Revision: 0
Instruction Cache [Kbyte]: 512 Processor Speed: N/A
Data Cache [Kbyte]: 1024 Processor State: N/A
Instruction TLB [entry]: 120 Processor Chip Revisions: 5.1
Data TLB Size [entry]: 120 2nd Level Cache Size:[KB] N/A
Serial Number: N/A

As you can see, Icache (memory) is 512k and dcache 1Mb and no 2nd level cache.

/usr/sam/lbin/getmen fails when more than 2Gb are instaled.

My peer has develop a C program which call to pstat_getstatic funtion. See man pstat.

[Alan Riggs]

Carlos is correct, though I think the cutoff is even lower. I have seen /usr/sam/lbin/getmem report inaccurate information for anything over 512Mb.

One more option:
grep Physical /var/adm/syslog/syslog.log

Im sorry,you are rigth.
