Get Win32 Total Physical Memory & Available Physical Memory stats
Hello. I've checked CPAN and have searched the net as well and have not been
able to find a Perl script or module that will get me the Total Physical
Memory and Available Physical Memory stats for a remote system, much less an
NT utility. The one utility I found, SYSTEMINFO.EXE can't be used to get
info on an NT4 system and I have plenty of them. I've found some scripts
that provide task mgr types of info but that's too much.

How would you go about converting a virtual memory to a physical
I'm doing a device driver and our company has developed a Common
Driver Design (CDD). One of the requirements is to convert the user's
virtual address of their buffers to a physical address. The driver
then uses that address to perform DMA operations on a PCI devices.
We have devloped this CDD for Windows and Linux with great success. I
now need to do it on a Solaris 10 OS.

I know memory mapped IO is about mapping device/controller registers to
memory space in order to reduce the number of processor instructions
(and simplify device driver writing) . My question is: are device
registers mapped to virtual memory or physical memory? I suspect the
former, and I have looked up a number of texts but everyone just seems
to skirt about the issue.

in sam (or as well in top) I can see two different parameters, one is
called physical memory and the other one is real memory. So far I used
these terms equally. I still assume that physical memory denotes to the
hardware mem chips I put in the server, but was is real memory?
The "memory management whitepaper". should give you some information
Once it was in /usr/share/doc/mem_mgt.txt; don't know whether this
exists in actual versions (And I do not pretend, that I understood it
completely ;-) ).
As far as I remember real memory is basical...shared memory segments
We have an application ( running under control of CICS) running under
AIX 4.3.2 . Parameters can be set which specify amount of memory
allocated for different usages. I think that the memory is shared
memory. The application is also running oracle, which uses shared
memory also. How can I be sure that changing the size of memory used
for 1 of these usages doesn't overlap memory used for another usage?
Specifically, three of the usages are for a Region Pool, a Task
Private Pool and a Task Shared Pool
.. The documentation for setting the size of the Task Private Pool

Does the addressable physical memory range depend on which slots are
occupied by the memory?
Say, I have a 32-bit CPU and 128M RAM, and the motherboard has 4 slots
for plugging the RAM in.
My question is if the following statement is correct:
No matter which of the 4 slots is occupied by the RAM, CPU can always
address the physical address range from 0-128M. In other words, when
CPU reads/writes data from/to the address 0x000000FF, it will always
succeed, no matter which of the 4 slots is occupied by the RAM.
Is this correct? Any help will be appreciated.

I need to find how much physical memory an hpux system has.
I'm familiar with Tru64 vmstat -p, but ux doesn't seem to have the -p
Any advice appreciated.
dmesg | grep Physical

I have a new db2 server and we are moving to V8. The box is running
W2K and has 12 gig of memory. The operating system is only showing 4
gig of it and that is one thing but when I pulled up the configuration
advisor from control center when it asked how much of the physical
memory to use for DB2 it only showed me 2048 not even the 4 gig the os
sees. I thought that Version 8 was past the 2 gig limit? I installed
fix pack 5 but still dont' see any more memory. Am I missing
