#OS2 not paging to disk
4 messages in this thread
Rendering 3ds4 under Warp I get "Render out of Memory" when I exceed the 64 meg
ram installed in the computer. From a virtual Dos window without the settings
modified the Scene Info shows 65 meg memory allocated at time of error message.
On a session using proper settings adjusted for 3ds4 Scene Info shows 79 meg
memory allocated at time of error message.
In short, the computer won't page to disk after running out of ram while
rendering. I do not have this problem rendeing under Dos without OS2. After
ram is used 3ds4 pages to disk to complete the rendering.
Does anybody have experience with this problem? Advice appreciated.

Peter…
Up your memory limit in DPMI settings regardless of your physical ram
this should allow you to render assuming you have the hard disk space to page
out to…
Your message seems a little confusing to me but if it's paging to disk
and then tells you it's run out of ram (virtual at this point) it could mean
you've run out of disc space.(I'm sure that's not it … too silly… but I've
done it before now! )
As far as I know there's no upper limit to
OS/2's virtual memory size… Actually if anyone knows different I'd love to
know.
You might also benefit from not running in a window… IE go full screen
DOS session.

Thanks for the note John. I've tried upping the DPMI setting to more than 256
with the same results. I can't believe I'm out of disk space since 300 meg
minimum is sitting free. And I do run in full screen mode. Can you run in
window mode? Nothing seems to let the rendering complete excepet staring out
from DOS. Then I had more than 500,000 paging faults.
Thanks, Peter Landeck
Hi Peter
I'm not entirely sure I'm understanding your setup correctly but a couple
of suggestions spring to mind… (sorry if they are silly and you already
checked… and er no it isnt a good idea to run it in a window.)
There is a setting in OS/2 config.sys (I forget right now which I'll check if
you cant find it) that needs to be set to SWAP before OS/2 will swap out.
Is OS/2 doing any paging at all can you tell?
The other thing is I think there used to be a problem with Himem not
recognising more than 64Mb ram. I think that's for IBM dos V6.3 . (I seem
to remember seeing a fix on their UK BBS for this)
I'm grasping at straws for you here though…
I do have a good text file for optimising OS2 I'll take a look in there to see
if theres any help. (I could e-mail it if you want it or upload it if anyone
else wants it.)
