The limitation of Virtual Memory

hi all.....
When exporting the huge data volume to excel, the process always terminated by time-out and dumps error.
I read a lots of post and SAP notes. I found the root cause of lacking of memory. I have 8GB memory on OS.The limitation of virtual memory in each process is 3GB after activating 3GB opotion in boot.ini, is that rigt?
If I want to use more than 3GB, I should upgrad to 64 bit machine, is that right?
OS : windows 2000 advanceed server on 32 bit
Physical memory : 8GB

just install additional dialog instance for your SAP system on any 64-bit platform as Eric said....

After upgrading to Lion, the Finder will increase the virtual memory while using external HD

after upgrading to Lion, the Finder will increase the "virtual memory size" while using external HD. I check it using Activity Monitor and found that "Finder" wll increase the "Virtual Memory Size" and "Private Memory Size". and then after a while. the system told me my HD is full and hanging there.
My External HD is 1TB. and I have installed new version Paragon NTFS for Mac V.9.01. I am not sure it is related or not.
but I attached my external HD. the "Finder" will start to increase the "Virtual Memory Size".
please help out this case and solve this issue.
thank you !!!

The one has nothing to do with the other. Virtual memory size and Private memory size are used by developers to analyze their software. it has nothing to do with anything related to the user.

How to change Virtual Memory in Windows 7 with SSD and 16GB RAM

I have SSD Samsung 850Pro with OS Windows 7 and have installed physical RAM 16GB.
In Adobe Help/Optimize performance/Photoshop written :
" To change Virtual Memory in Windows 7 and Vista, quit all applications and then do the following:
Choose Start > Control Panel, and double-click System.
Choose Advanced System Settings in the Tasks list.
Select the Advanced tab and click Settings in the Performance section.
Select the Advanced tab and click Change.
Deselect Automatically Manage Paging File Size For All Drives.
Click each hard disk letter to show the available space on that drive. Select a hard drive that has three times the amount of your computer’s installed RAM and doesn’t contain a scratch disk.
Select Custom Size, and type the amount of your physical RAM plus 300 MB in the Initial Size box. Type three times the amount of your computer’s installed RAM into the Maximum Size box.
Click Set, and then click OK. Continue to click OK to exit all dialog boxes.
Restart the computer: If you have applications open, select Restart Later, close your applications, then restart Windows. Otherwise, click Restart Now. "
Select Custom Size, and type the amount of your physical RAM plus 300 MB in the Initial Size box. Type three times the amount of your computer’s installed RAM into the Maximum Size box.
I have 16GB RAM
in the Initial Size box : 16384+300=16684MB
in the Maximum Size box:16684x3=50052MB
but in the description of SSD written :
" In order to address any potential lack of memory capacity, the Windows operating system automatically generates a block of virtual memory (pagefile.sys) on the C: drive. For example, a Windows® 7 64-bit system with 4 GB of physical memory would generate 4 GB of virtual memory at boot time.
In the past, before PC Memory (DRAM Modules) were available in high volume, PCs needed to utilize some HDD space to address any memory shortcomings. Today, with PCs featuring 4 GB of memory or more, it is possible to reduce or even eliminate the use of virtual memory. Additionally, using expanded physical memory, rather than creating virtual memory on the SSD, has performance and reliability advantages for the entire system. Some applications may require the use of virtual memory. In this case, please consider your specific application requirements before disabling this feature!!! ”..."SET virtual memory in the Initial Size Box :200MB and in the Maximum Size box: 2048MB"
what is the right choice ???
Please Help

Windows set to default virtual memory : 16348 MB =16GB !
But SSD program Samsung Magician wants virtual memory between in the Initial Size Box :200MB and in the Maximum Size box: 2048MB or 4096MB. If more than 8GB suggests that SSD will work slowly.
Perhaps the description in Adobe execution Help / Optimize / Photoshop is not correct or ?

Windows 8.1 RDP Virtual Memory Error

I just upgraded to Windows 8.1 and am encountering the same problem as mentioned here:
http://social.technet.microsoft.com/Forums/lync/en-US/068228a3-78da-4bcf-acb5-3cf5c63dee48/windows-81-preview-remote-desktop-failing-with-low-virtual-memory-error?forum=w81previtpro
I am trying to use RDP desktop version to connect to a site (which uses RD Gateway). It says "Initiating Connection" and then fails with no error or any notification (there is nothing in the event viewer)
If I try changing settings (removing sound from RDP, reducing resolution) I eventually get this message:
[Window Title]
Remote Desktop Connection
[Content]
This computer can't connect to the remote computer.
The problem might be due to low virtual memory on your computer. Close your other programs, then try connecting again. If the problem continues, contact your network administrator or technical support.
Connection worked fine on Windows 8 - is this a known 8.1 bug? It is pretty critical for me!
Thanks

Hi,
Since I cannot repro this issue, I considered that following factors may cause this issue:
Paging file value setting is too low.
RAM issue
First, I suggest we try following steps to check the issue:
Step 1: Increase page file size:
How to Change The Size of Virtual Memory (pagefile.sys) on Windows 8 or Windows Server 2012
http://blogs.technet.com/b/danstolts/archive/2013/01/07/how_2d00_to_2d00_change_2d00_the_2d00_size_2d00_of_2d00_virtual_2d00_memory_2d00_pagefile_2d00_sys_2d00_on_2d00_windows_2d00_8_2d00_or_2d00_windows_2d00_server_2d00_2012.aspx
Step 2: Run Memory diagnostic tool:
From Start, type mdsched.exe, and then press Enter. Normally, text that you type on Start is entered into the Apps Search box by default.
Choose whether to restart the computer and run the tool immediately or schedule the tool to run at the next restart.
Windows Memory Diagnostic runs automatically after the computer restarts and performs a standard memory test. If you want to perform fewer or more tests, press F1, use the up and down arrow keys to set the Test Mix as Basic, Standard, or Extended, and
then press F10 to apply the desired settings and resume testing.
When testing is complete, the computer restarts. You’ll see the test results when you log on.
If this issue still persists after above steps, I recommend you helping to do following test and let me know the results:
Start Windows in Clean boot mode, and open Remote desktop and see what’s going on:

Frequent low virtual memory on my A45-S120

I frequently get a flag warning of low virtual memory. I suppose I need more RAM. I am a novice at this. Can RAM be downloaded ? If I need to buy an item where do I get it? I live in Mazatlan Mexico.

According to the specifications at Toshiba's website, the A45-S120 came with 256 MB of memory, so it's no wonder that you are getting virtual memory alerts. You can increase the amount of virtual memory Windows allocates by following the steps in this article:
http://support.microsoft.com/kb/308417
If you feel like spending cash on that old machine, then upgrade it with more physical memory. For maximum compatibility, use Kingston KTT3614/512 or KTT3614/1G modules. Increasing the physical memory will generally make the computer more responsive.

Use Secure Virtual Memory - An observation

I recently noticed that my MacBook Pro, with a fresh install of Snow Leopard, had the item "Use Secure Virtual Memory" checked in the Security Preference Pane. A little research on these forums and I learned that was a new feature of Snow Leopard and it is on by default for portable computers and off by default for desktops.
The threads that I read in researching this touched on who needs this turned on and why as well as potential performance implications of having this turned on. The general message was that the load on the CPU would probably not be noticeable given the disparity between disk performance and CPU performance.
I had used my freshly rebuilt MBP with this option turned on for a couple of weeks when I noticed it and turned it off. While I'll agree that from a performance / response perspective I noticed no difference between it being on or off there was another measurement that did show a noticeable difference. I always run temperature monitor, including my CPU temperature, on my MBP, it ends up being sort of an early warning when something is beginning to make the CPU work harder than normal. Since turning off the "Use Secure Virtual Memory" option I can confidently say my typical CPU temperature has dropped between 6 and 9 degrees Fahrenheit for each working set of applications / activities that I do with my computer. So while there may not be a performance gain per se, clearly the CPU is working a little less with this option off.
Just wanted to share this for others to make an informed performance perspective decision on using this option.

It seems like the default for Mac Laptops is ON, while the default for Mac Desktops is OFF...

"Use secure virtual memory" doesn't encrypt swapfile

System: Fresh install 10.5 with full patches to 10.5.1 G4 iMac.
No matter what I did with the "Use secure virtual memory" option in System Preferences, the -E switch did not get passed to dynamic_pager.
Setting ENCRYPTSWAP=-YES- in /etc/hostconfig also had no effect.
So I forced it in /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist and verified that the -E switch is being passed to the dynamic_pager on startup. Guess what? The swapfile still appears to be in-the-clear.
So I thought the contents of /var/vm/swapfile0 might be left over from a previous boot so I booted into single-user and ran +rm -P /var/vm/swapfile0+ then booted normally. Still appears to be in-the-clear:
root# strings /var/vm/swapfile0 | grep -i password
2/Applications/Utilities/Open Firmware Password.app
*/Applications/Utilities/Reset Password.app
com.apple.openfirmwarepassword[
com.apple.OpenFirmwarePassword

Contents/Resources/PasswordReset.icns
Contents/MacOS/Reset Password
root# ps -ax | grep dynamic_pager
72 ?? 0:00.01 /sbin/dynamic_pager -E -F /private/var/vm/swapfile
The technical term for this is "BAD."
*Is encrypted swap a feature of Leopard or not?*
I've seen discussions that this also applies to Leopard Server. I haven't looked at Tiger client or server yet.

I was looking at this myself, more so because I was having performance issues and wanted to see if secure virtual memory was worth it. I encountered the same issues you had with the "Use secure virtual memory" checkbox. It seems that it isn't working. But then I spent like 5 minutes trying to understand the explanation in help:
Use secure virtual memory: Select “Use secure virtual memory” to erase any information from random-access memory written to the hard disk by virtual memory.
Keyword here is "erase" not necessarily "encrypt". This is my understanding of virtual memory. Let's say you have some application that uses a password. that application gets pushed to virtual memory. You access the application so it gets placed back in RAM. When this happens, and if you have secure virtual memory enabled, it will erase the information from the virtual memory. Without secure virtual memory that information still lingers in there till reboot and the swapfile is cleared. It's not necessarily encrypted though.
Now, why when you specify the -E option and it doesn't encrypt the swapfile I'm not sure. the man page is rather vague, but does say that -E encrypts the swapfile.

When playing games on facebook, I often get the message "virtual memory too low, is being increased" Is there something I can do to clean out the "virtual memory" to avoid this?

As mentioned in my question above, it happens usually during playing games. I wondered if there were someway to clean out the virtual memory, as opposed to it "increasing" continually and overloading my memory in general. You are speaking with a computer novice for the most part, so I am unfamiliar with a lot. I do do updates and general maintenance on the computer, but is that enough for this issue?

Physical memory is the memory that is installed on your computer as real memory. To be able to run programs that require more memory and more programs at the same time (via time sharing and task switching) it is also possible to move (swap) currently not needed code and data to disk to make room for other programs and data. The total memory available for programs is the Virtual Memory.
You can check the Virtual Memory settings here: Control Panel > System > Advanced > Performance > Settings (Advanced tab) 
Windows can manage more memory then is physical available and that memory is stored in a page file on your hard drive.
If the size of that file is not large enough and all available memory is in use then you get the Virtual Memory is low warning.
Make sure that you have at least 1 GB or the recommended setting for the Virtual Memory.
If you have less than 1 GB physical memory installed on your computer then if possible add more memory.

What the heck is going on with my Virtual Memory??!!

I'm not really sure why but when I check activity monitor and see my VM it says i'm using anywhere from 230-270 gigs of virtual memory. This is literally fresh out of restart when it says this much and never changes. I go through and check every process I see runing and create a quick estimate of the virtual memory being used, and it's definitely not over 10 gigs if even 5; honestly I think it's listing between 1-2.
What the heck could be causing this? Verified HD and came up clean. Should I be concerned? I'm not gonna lie this macbook isn't running the best it used to be. Watching videos, whether mp4, mkv, youtube, is pretty laggy. I'm aways sure to close all other processes to to try and maximize video performance, not that it helps much. I'm considering a fresh install and recovery via timemachine.

The merge process could not allocate memory for an operation; your system may be running low on virtual memory. Restart the Merge Agent.

I encountered this problem on our SQL2012 and I have tried different scenarios (see below) to no avail. I have decided to give up and check if someone here has encountered this and resolved it.
One thing I know, it's not a memory issue. Both servers we're using has lots of memory to spare and we monitor the memory as the replication goes through it's steps.
I hope someone can help me on this. Thanks!
The Error:
The merge process could not allocate memory for an operation; your system may be running low on virtual memory. Restart the Merge Agent.
Our Scenario
We're using SQL Server 2012 SP1. All subscriptions are pull based.
We're using direct Merge Replication (not FTP or web sync)
We already have 10 active replications with larger databases. Only 1 has this issue.
Database size is less than 5 GB
Rebuilding the publisher is not an option.
What have I tried?
There is no memory problem --- we have lots to spare
I have tried re-initialization of the database. Same problem.
I tried deleting the database and reinitializing it. Same problem
New snapshot. Same problem.
I tried changing the subscriber server but still same issue.
MCP, MCSD, MCDBA (ANXA)

Here is the result for the sp_configure on our subscriber. We're doing a pull on the server with the issue.

config_value
run_value
max server memory (MB)

2147483647
2147483647
In addition, I made a comparison between the working servers and the one with the issue -- there seems to be a difference in the service pack. Publisher has none but the subscriber is operating on SP1. But still strange as only 1 database is affected.

The old allowing oracle 3GB virtual memory on windows 2003 server question?

Hi all,
I have a 9.2.0.7.0 database on windows 2003 server (32bit). 4 dual core cpu's and 16GB of Ram.
I have set .use_indirect_data_buffers=TRUE and *._enable_NUMA_optimization=FALSE.
The db_block_buffers is set at 4GB.
Shared_pool 200MB
Large_pool 56MB
Java pool 56MB
PGA is currently at 400MB
AWE_WINDOW_MEMORY is set at 720MB (which is the lowest I can set it)
At the moment there are various jobs running on the database and no users logged on and the virtual memory is at 1.8GB.
The problem is as soon as the users logs onto the DB the virtual memory goes over 2GB and we see the error 'ORA-04030: out of process memory when trying to allocate 2416 bytes'.
Now I have edited the boot.ini with the following parameters:
multi(0)disk(0)rdisk(0)partition(1)\WINNT="UBS WSP - Wintel Server Platform with PAE" /fastdetect /PAE /4GT
because the /3GB parameter switch started the server with lots of errors.
The oracle.exe process still seems unable to go over the 2GB limit with getting 'ORA-04030' errors.
Can someone tell me if I have missed anything? Or a reason why oracle is not using the switch?
TIA
Eddy

Satish,
see metalink Note:1036312.6 : Utilizing Up to 3GB Virtual Memory on Windows.
it says :
"The 32-bit versions of the Windows® 2000 Advanced Server and Windows NT Server 4.0, Enterprise Edition, operating systems were the first versions of Windows to provide applications with a 3-GB flat virtual address space, with the kernel and executive components using only 1 GB. In response to customer requests, Microsoft has expanded the availability of this support to the 32-bit version of Windows XP Professional and all 32-bit versions of Windows Server™ 2003."
of course, we mustn't be mistaken with the AWE switch (/PAE) that is not available for standard edition.

How to change the optimal virtual memory

Hi, i use a tevra m2 1.8 GHz 512 MB laptop.
normally used for office work and not for gaming,
antivirus bitdefender consumes lots of memory so one has to be cautious on using memory.
so i was wondering if anybody knows how to configure the best the 'virtual memory' : min and max : about 1.5 and 2 times the RAM-size ?
Thanks in advance

Hi
Please go to:
System Properties - "Advanced" tab - Settings in the performance area - "Advanced" tab - "Change" button
There you will find the Virtual memory settings.
I would recommend setting the settings to "System managed size". In this case the OS will control the value automatically.

Thanks a lot.
HASPJava.dll is used by verification License and is invoked less and can't use a lot of native memory.
Our business is communicating between java and COM component. In order to implement it, we used JavaCom to generate java class for COM component.
Memory of COM component is little, but Native Memory is high.
Who used JavaCom and did you meet this problem?
Please give me some suggestions. Thanks a lot.

How can one use the physical memory of our system rather than virtual memory while running Labview?

We have a Windows NT system with 2 Gb of physical memory and would like to utilize the RAM fully using Labview. What usually occurs is that Labview uses a tremendous amount of page file space while a majority of the physical memory is unused. Is there a way to configure Labview (or our system) to overcome this problem? It seems that our processes would be much faster if they were mainly using the physical memory. Is it possible to trick the system, by creating a RAM disk and allocating this as virtual memory space?

LabVIEW the application doesn't know anything about physical versus
virtual memory. LV asks the OS for general purpose memory and goes
from there.
Drivers like DAQ and IMAQ will have a combination of general user
memory and page lo
cked physical buffers.
I'm not up on the details, but this is something that the OS is in
control of, so that is where you need to look for the solution. One
of the things to look at is the disk cache. By default, I think that
NT takes a percentage of the RAM to use for disk cache. With that
much RAM, this is probably unnecessary and is using too much.
Similarly, the OS may be attempting to keep the working set size
to a fraction of the total RAM to reserve space for other things.
It doesn't make sense to me, but then I don't work for MS.
