Doc. told us the the min RAM for installation is 512MB so I can
install Oracle . Beside I can not install more RAM because My machine
is PIII . That the maximum for it .

Use the Crucial site, to determine whether the computer has memory
expansion options or not.
Depending on the vintage of the computer, there were some motherboards
with a 512MB limitation. Intel made a chipset once, where there were
three slots for installing RAM, a slot could contain up to a 512MB
capacity stick of RAM, and yet the overall machine was limited to 512MB.
This was a strategic error on Intel's part, intended to make customers
angry.
So check the system details, and see if it is possible to install more RAM.
When installing the RAM, the important things to remember are.
1) Turn off the power to the computer. Unplug the power cord so
there is no stray power inside the computer chassis. Do this
after doing a normal system shutdown (not standby).
2) Verify the notch in the DIMM, aligns with the key in the DIMM slot.
Also check that the dimensions and number of contacts on the module,
match the memory slot on the computer motherboard. Don't apply
downward pressure to snap the module into place, unless you're sure
the module will fit.
One "genius guy", bought memory for his computer, and the notch in the
memory DIMM, didn't line up with the key in the slot. Being clever, he
decided to take a hack saw, and cut a new notch :-( This is a bad thing
to do. The notch system is intended to prevent the wrong memory from being
installed, or it can also prevent the module from going in backwards.
If something isn't fitting right, ask questions first.

Apparently Doc. was wrong.

Then this machine can't have that software installed on it.
Really, how did you grow up without learning to combine pieces of information
to reach conclusions? Do you ever have trouble crossing the street? I can
just see you asking for help with street crossing:
Hello, I need to know whether there are cars coming from either
direction. I looked left and I saw three cars, two of them parked,
and one where I can see tail lights. I looked right and I saw one
parked car, and one moving with headlights on and facing me. Is
there any traffic coming?
If you'd just, you know, *think* about the information you have, and combine
it, you wouldn't have nearly as much trouble.

Or it wasn't the documentation for the version that's going to be
installed (or for a different OS). E.g. on the page with the re-
quirements of the "11g release 1" for Solaris
http://download.oracle.com/docs/cd/B28359_01/install.111/b32068/pre_install.htm#CHDCEBFF
it's stated that at least 1 GB is required (but then this might
again be the documention for a different version or OS).

Peter, do you really think that was necessary?

I don't know. I suspect it's pointless, but I have seen people who actually
started to think once they'd had it pointed out to them that they did, in
fact, have all the information they needed.
Not very often, but I usually try a couple of times before I plonk someone
for being ineducable.
No answer to any technical question will help him if he can't combine
information to reach conclusions. If he can learn that, he won't need
to ask 90% of the questions he posts today.

Can I increase other kernel parameters to make this barrier pass as an
alternative of increasing Ram ?

Let's review:
1. You ran the Solaris Software install program on this machine.
2. Solaris installed fine.
1. You ran the Oracle software install program.
2. The Oracle software install program failed, saying you need to
double the amount of RAM in your machine.
Why are you asking if there are settings you can tweak in the Solaris
kernel? Solaris didn't refuse to install in your machine. Oracle was
the thing that refused to install.
Why aren't you asking in the Oracle newsgroups?

Was the documented requirement of 512MB physical RAM, for the
release of software you were installing ?
I don't know the details of the Oracle installer. If it was
using a shell script, you could try commenting out the
test for physical memory.
There is mention here, of a "percentage of memory usage" parameter.
http://forums.sun.com/thread.jspa?threadID=5385455
Do you have an installation manual for the product ? I can't
find a reference to that parameter.

Replace your machine! PC's supporting 4GB of RAM are available. I
suspect that any of them will run rings around a Pentium III!!

If you do so, be prepared for extremely poor performance or refusal to
function at all! Your best bet is to install AT LEAST the minimum
memory recommended by Oracle. More is usually better! Also note that
Oracle has some pretty strict standards for number of disk drives and
number of disk controllers. I believe that the minimum is five disk
drives and two controllers. The systems I've installed Oracle on had a
good deal more than the minimum memory, two or more disk controllers and
eight or ten disk drives.
If Oracle is not the best database program around it's close. It *may*
be more database than you need. If you don't have an experienced DBA,
you should probably hire one or send one of your people to school to
learn how it's done! You might want to pay Oracle for the services of
one of their technical people to help get you and your people up to speed.
Joe Young
around with an old machine at home in order to see what can be done
then that should be encouraged I think. Yes, it's smart to look at the
output and then deduce what should be done. But, on the other hand, he
did ask if it was possible to tweak the installation procedure to get
round his limitations. And it is indeed possible. So his question
wasn't nearly as stupid as it has been made out to be by some of the
replies that he had. I think more fairness could be extended in such
cases.
Joe Young
I don't know if you're still reading this thread now that you've got
your answer, but if you are, you might want to pre-empt some of the
irritated replies that you're likely to get from technical folks and
geeks who place great store on attention to detail, by (a) explaining
why you can't do obvious things like buy a new faster machine (because
you've got no money) or fit more RAM. I see you did explain that by
showing that your machine doesn't support any more RAM. Well done.
You might understand perfectly well why you can't get a new faster
machine. But we won't know why not unless you tell us.
I hope you have a less irritable response to your next question.

If he is really fiddling around with a home system, his question is
"under specified". You *can* do a lot of things on a small home system
IFF you don't expect things to work to a commercial standard.
If a poster doesn't say otherwise, we have to assume that he's
installing Oracle for use as a real database that is expected to
function correctly and provide good performance!

If it requires 922MB of physical memory to *install* the program,
I hate to think of what it takes to *run* it. It's approaching the
rumored version of Windows 666 which requires a minimum of 4GB to
boot the first-level bootstrap, complete with 3-D movies of the
birth of Bill Gates to display during the boot process.
Yes, it's probably a good idea to warn if there isn't enough horsepower
to run the app you're installing, but preventing it on a system that's
upgradeable doesn't make sense.
A decent virtual memory system ought to be able to (but I suspect
this disqualifies most OSs out there) run with very little user-process
memory (although it will be far from fast). For example, if pages
are 4Kbytes or 16Kbytes, it shouldn't be panicing with 128Kbytes
of user-process memory, assuming the standard system library takes
2MB. You might get performance equivalent to a 1KHz processor out
of one that supposedly runs at 2GHz, and it might not be able to
keep up with a mouse or a 1-finger-typist user typing ahead on a
110-baud teletype. If the product has annual updates, you might
find it takes more than a year to install one of the updates.
One reason you might want to do this is to install the software and
set it up while waiting for approval for the additional memory, or
waiting for it to arrive.

Your Oracle requires 512 MB of free RAM. Your PC has 512 MB total RAM,
and the Oracle installer only could find 508 MB of free RAM. Thus, the
installation failed, as designed.
Richard B. Gilbert
The obvious solution is to install more memory! Many PCs will support
4GB of RAM (four 1GB DIMMs). It's not terribly expensive these days.
If, for some reason, the machine will not support more RAM you will have
to either get a machine that will support a minimum of 1GB or limit
yourself to software that your hardware WILL support!
I would suggest that you "MAX OUT" the RAM; 512MB is only the
*minimum*!! It will make a large difference in the performance of Oracle.
Also note that Oracle wants a MINIMUM of FIVE physical disk drives for
its exclusive use. More may be better. For best performance you may
want to install additional disk controllers.
If you were thinking of running Oracle on a typical desktop computer,
you are almost certainly thinking TOO SMALL. A *SERVER* type machine is
the way to go.
If you don't have an experienced Database Administrator, consider hiring
one. I'm not one but I've worked with a couple! It really helps to
have someone who knows how!!!
