RE: [ActiveDir] Pagefile not being seen?
Thanks, Chuck. If I had more users on these Exchange servers, I'd buy
more memory. But, there are only about 300 users on each one, so I'm
thinking upping the pagefile will do the trick. But, as I wrote to
Kevin, I couldn't get the total pagefile on all drives to be 4GB unless
I split it up between 2 drives, which is not what I expected.

It's better to use 2x installed memory for Exchange as a
starting point. Splitting the page file on separate physical disks
should be OK as long as it is a total of 4 GB. Depending on the how
much messaging activity you have you might want to bump up the memory to
4 GB and then the pagefile would need to obviously be increased
substantially to about double the installed memory.

Check out this article for the Exchange memory settings. There
are a
few other tweaks in the registry.

Do you have any third-party apps running on your Exchange
servers? I
have seen memory leaks in third-party apps cause this kind of
virtual
memory issue.
2K3 Standard does allow 4GB on a drive. The way you have it set
up with
2048 on two separate drives will give you a performance boost if
they
are actually separate physical disks or RAID sets.
I have typically heard 1.5 times physical for virtual, but I
don't think
that is as much a best practice as a general rule of thumb.
Depending
on circumstances I have certainly set it lower or higher. 4 GB
virtual
should certainly be enough.
Sorry for the random order of my answers. I also have trouble
following
directions and don't play well with others.
Hope this helps

Subject: [ActiveDir] Pagefile not being seen?
Colleagues,
On two different Windows 2003 servers in as many weeks I have
seen a
popup when I logged in that says "Your system is low on virtual
memory.
Windows is increasing the size of your virtual memory paging
file.
During this process, memory requests for some applications may
be
denied."
On one server, I had 2048 pagefile on C. On the other, I had
4096
pagefile on C, but the note at the bottom of the screen showed
only
2050. Both servers have 2Gb physical RAM, and both are Exchange
2003
servers. I have now put 2048 on C: and another 2048 on F: on
both
servers.
So, I wonder if I have things set up right, so I have a few
questions:
1. Isn't the pagefile limit in 2K3 Standard 4Gb per drive as I
have
read? Or is it actually 2Gb per drive?
2. With 2Gb physical RAM, isn't 4Gb pagefile the standard?
3. With the /3GB and /USERVA=3030 switches set, which is what I
learned
to do in class, why do I still get the Event Log error message
that says
"The memory settings for this server are not optimal for
Exchange."?

RE: [ActiveDir] Pagefile not being seen?
Thanks, Kevin. Yes, I had read that article before I posted, but it seemed that I had things set right. When I put 4096Mb pagefile on one drive, hit the set button, and reboot, coming back to the screen just before you set the pagefile on all the drives, it still says 2050 total pagefile on all drives. When I set 2048 on two different drives, then I get the correct number, 4096 total pagefile on all drives. Still a mystery. And, what's more, when I changed from 4096 on drive C to 2048 on C and another 2048 on F, it took two reboots before the total pagefile on all drives went up to 4096 as expected. -- Larry Wahlers Concordia Technologies The Lutheran Church - Missouri Synod mailto:[EMAIL PROTECTED] direct office line: (314) 996-1876 > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Kevin Brunson > Sent: Wednesday, December 06, 2006 2:32 PM > To: ActiveDir@mail.activedir.org > Subject: RE: [ActiveDir] Pagefile not being seen? > > Check out this article for the Exchange memory settings.
