Warnings on the use of virtual memory machine

Hello

Have a question about the difference between ESX 3.5 and vSphere 4. I have 4 vSphere ESX 3.5 and 2 4. On ESX 3.5, the memory usage is much lower, then the ESX 4 for the same machine virtual.

Example: SVR2003 TS with an average of 20 users defined, running the same application.

On ESX 3.5: HP ProLiant DL380 G5 with 16 GB of memory, two processors running on 3 GHz (4 logical processors without Hyperthreading)

Granted memory: 2.134.016 average KB

Active memory: 313.342,33 average KB

On 4 ESX (vSphere) HP Proliant DL380 G6 with 16 GB memory, Quad processors running on 2.8 GHz (16 logical processors with Hyperthreading)

Granted memory: 2.097.152 average KB

Active memory: average 1.987.864,5 KB

As you can see there is a big difference in the use of mem. We therefore always mistake alerts and warning of our Center Virtual whiel I can find nothing on the configuration of the virtual servers, as well as on the machine of vmware.

Does someone had the same problem, and what can we do about it...

THX

This was thoroughly examined several times.

See http://communities.vmware.com/thread/211585?start=90&tstart=0.

Make sure you have the hotfix mentioned in http://kb.vmware.com/kb/1014019 installed.

Use of the memory of the guest operating system may be overrated on systems Intel that supports technology EPT or AMD supporting IVR technology. This issue may cause alarms memory in vCenter falsely goes even if the client accesses not actively a lot of memory.

  • How to limit the size of virtual memory dedicated to the JDK 8?

    Hello

    I use JDK 8 on Solaris on x 64 box 11.1:

    Java $-version
    Java version "1.8.0_11".
    Java (TM) SE Runtime Environment (build 1.8.0_11 - b12)
    Java for 64-bit Server VM (build 25.11 - b03, mixed mode)

    I am running tomcat/xwiki on top of that. I set myself as a result of operating options to limit the use of memory in Java:

    CATALINA_OPTS = "" Server - d64 - Xms1024m-Xmx1024m - XX: MaxMetaspaceSize = 1024 m - XX: MaxPermSize = 196 m-Dfile.encoding = utf - 8 - Djava.awt.headless = true - XX: + UseParallelGC - XX: MaxGCPauseMillis = 100 ' "

    These params are from the same time project JDK 7 served so I left - XX: MaxPermSize here even if it is no longer supported and I just added - XX: MaxMetaspaceSize = 1024 m for JDK 8.

    My problem is that when I put server under a load to push new sound REST API to the XWiki pages, then I see RSS (in prstat) hovers around 1.5 GB, but the growing SIZE and the entire process to push pages on the server becomes slower and slower.

    The problem is that I am not able to detect any obvious memory leak using jconsole or using visual vm and the dump of the heap. They both claims that, all in all, my JDK consumes up to 2 GB of RAM. The only exception is jconsole, in his summary of the VM pane, tells me that the amount of "committed virtual memory:" occupies about 14 GB, which corresponds to the observation of the utility value of SIZE of prstat.

    I do not like the idea of JVM consumes more memory with possibility not to stop in this process, I would like to ask if there are any parameter which will allow me to set the memory hard limit can be used by any JVM?

    Any idea is appreciated here,

    Thank you!

    Karel

    Just a follow-up. It seems that this probably isn't problem with JDK se. The problem more and more memory is caused by Apache Solr, which uses the memory-mapped file access and this adds to the amount of virtual memory. It also explains why he is not counted in the amount of heap memory.

    In any case, some kind of help on this will be appreciated in either visualvm or jconsole. For example jconsole should at least add an indicator to virtual memory committed that it contains also the memory mapped files or something like that.

    Thank you!

  • How to set the use of video memory on the graphics card to my laptop cq56-110us?

    Hello

    I have a PC Compaq laptop CQ56-110us.  Windows 7 says is has 797 MB video memory shared from the main memory of 2 GB.  I want to reduce the use of video memory, i.e. 256MB.  Is this possible?  If yes how.  I would appreciate help with this.

    Thank you

    Don

    Don, welcome to the forum.

    Built-in memory is allocated by the system.  As more video memory is required, is allocated.  There is no way that you can change.

  • Impossible to change the settings for virtual memory by using Fusion 5 on MacBook Air

    I use VMWare Fusion 5.0.3 and I'm trying to start a picture.  The image complains that I need to reduce the virtual memory settings.  I go to settings: processors and memory and reduce from 4 GB to 2.5 GB image. There is no button Save, so I click on the red X.  I tried this several times using several ways to access the settings and that you can save them using any combination.  I started a VMWare image which has 2 GB configured 'work' and was unable to change these settings as well.  My MacBook Air has 4 GB of physical RAM.

    Okay - problem solved, but do not really exactly know how; but Dariusd started me in the right direction. I was at VMWare 4.1.x last week and recently updated to v5.0.3. I don't remember having these problems before. When I launched my VMWare image running in v4.1.x around v5.0.3, initially asked me if I wanted to move the VM and I said no.  I restarted the VM today (after having deleted all files and not pumped up the images once again) and responded yes, this time to upgrade. However, just after I tried to upgrade the virtual machine I got the error message "not enough of memory" again. So I then when in the parameters, as Dariusd suggested and changed the number of processor to 1 and changed the value of memory: However, it did not work. BUT, I did it again, changed the number of processors to 4 and then lowered the memory to 1024 as VMWare has suggested. IT WORKED! So I don't know if it was the attempt to upgrade the size of memory VM (which I doubt) or change to 4 processors as well as the update of the memory. Be it, I'm in place and thank you!

  • KB973687 - msxml3.dll msxml6.dll - services.exe uses excessive virtual memory, the performance impact on the first logon after restart

    Since the installation of fix KB973687, I had several SP2 and SP3 systems exhibit behavior that makes them unusable until after the first logon is completed, which can take up to 20 minutes.   I've identified the patch (KB973687) and DLLs, that it will update the origin of the problem, but uninstalling the patch does NOT return to normal operation.

    I need to understand how to upgrade these systems WindowsXP SP2 and SP3 to restore normal operation, reinstalling Windows, programs, and settings is an expensive solution.

    The performance problem is caused by services.exe slowly consumes about 1.5 GB of virtual memory, and then slowly releasing.  This seems to be triggered by the first logon after restart, this connection is very slow, the screen is blank for most of it, there might be failures of allocation memory during logon.  Once complete this opening of session and memory usage returns to normal levels, recording and return to work normally as do other operations until the system is restarted.

    Spent a lot of time working with SysInternals Process Explorer, trying to find what specific service might be involved, lightweight system for bare essential services with no luck.

    KB973687 seems to offer only two files msxml3.dll and msxml6.dll.  Uninstalling this patch, resettlement V3 and V6 of the XML parser fail to restore normal operation.

    Not all systems seem to have place still restrict the differences.  Systems that are appear to be the oldest, with Windows XP has been installed for at least a year, installed Microsoft Office and Adobe Acrobat.

    Looking for these forums and the Internet, I believe that many have encountered this problem, but have not is it this level of analysis, seem most attribute it to a virus, I see several start explorer.exe manually, I didn't know all the alternatives before reinstalling Windows.

    Found the solution, the following has been fixed in System Cleaner of Comodo 2.2.129172.4:

    "For some strange reason, after changing some settings of the system with the CSC LastGood.tmp Directoy began to constantly be read from my hard drive. This would occur up to about 90 to 99% of my memory was used and then stopped, begin to free the memory, and the system began to slowly to function normally.
    I used the process explore from sysinternals to help diagnose the problem with any process other than services.exe using memory.

    I used sysinterals filemonitor to see LastGood.tmp directory has been read repeatedly.
    After you have uninstalled CSC the problem has been resolved. »

    Even with the effort to find the solution, it was better to reinstall.  Hope this solution helps others.

  • virtualization of material assistance and the use of physical memory

    workstation6.5 use any technology hardware support? In addition, the virtual machine uses all physical memory? I find there's a .vmem file that I think it's a kind of memory for the virtual machine file. It would be even better to use the memory of phsicial, or Don't matter? I used Microsoft VPC and VMWare is new to me.

    Thanks in advance

    Yes. See products VMware and hardware support for virtualization (VT-x/AMD-V).

    Yes, indeed.

    I find there's a .vmem file that I think it's a kind of memory for the virtual machine file.

    This file contains the image of the memory of a suspended virtual machine.  When a virtual machine is suspended, it uses all of the physical memory.

    I did all the steps and my computer is a memory and it is already 735 and I changed it to 736 how high I can go

    * original title - virtual memory how high for Ko mine is 736 *.

    If you're referring to the size, you must configure the paging file, I recommend you leave Windows magage it. Generally, it must be set to 1.5 times the amount of RAM you have installed. See links for more information below:

  • UDP error 61 the cRIO - but the use of controller memory is < ~ 70%

    Hi all

    I'm having a problem with a program that runs on a cRIO-9074.

    My controller code has 3 parallel processes (for the 3 banks in my controller) that each contain 3 while loops. Reads an array of FXP in a FPGA DMA FIFO values and pushes this table in a queue. The following loop then reads the table from the queue, it throws in a string, split that string in size of the UDP and puts these substrings in a second queue. The final loop reads a substring from the second queue and forwards via UDP.

    Basically, a producer - consumer consumer/producer-architecture.

    Now this works very well in my development version of spaghetti with just a first level vi code. To make things more readable even if I compacted things into subvis, using global variables when it is necessary to connect them.

    My code is executed, but I get frequent errors during the broadcast channels UDP:

    «UDP - 61 error: the system could not allocate required memory.»

    I checked the memory usage from NOR distributed systems manager and my memory cRIO has a pretty decent amount of overhead. The sampling rate reduction - and corresponding memory use - does not make a big difference to the system time can go errors before. Even by reducing the sampling frequency straight down and disabbling that all except a loop (e.g. a Bank), I always get errors.

    How I debug this?


  • the use of virtual cards

    Hello!

    I'm working on a LabVIEW code that uses 5 cards OR (6503,6023,6023,6503,6704). I want to simulate these cards. So I created or daqmx simulated maps. When I run the labview program, I get the error-10401 when I try to use DIOconfig.vi. For more information, I use the traditional daq 7.4.2 driver.

  • Question about the use of EM on machine with 2 active instances

    Hello

    As a free workout, I created 2 instances on a single machine. The machine is, server and client. I'm running Windows XP SP2, Oracle 11 GR 2 (as seen in my handful of user) and using IE7 for MS.

    The URL of the first instance is:
    https://Oracle2Day1.john.local:1158/em
    The URL for the second instance is:
    https://Oracle2Day1.john.local:5500/em
    If I connect to one and the same instance, then everything works fine.

    When I log you at first, then in the second instance, and switch back to the tab of the first instance, I find myself back at the page "user name/password / Connect as", even I don't get the page saying that I was disconnected in the first instance.

    Of more, if at this time, I return to the tab of the second instance, I find myself on the page "user name/password / Connect as ' for this instance too.

    Basically, whenever I log in proceedings and switch to tab from one case to another, it brings back me to the log in page for both instances.

    If I connect in one instance and do not try to connect to the second instance then everything works fine.

    Any ideas as to why I can't be connected to two instances at the same time? (I myself can be connected in two cases, simultaneously using SQL * more without any problem) Is there something I can do to fix this or is it "normal"?

    Thank you for your help,

    John.

  • the use of an answering machine with a netconnection

    I'm using Flex and tries to call FMS3 via a netconnection. I want the machine to return values in Flex.

    Basically, I just call

    theNetConnection.call ("myFunction", new responder (hadSuccess, wasFailure));

    private void hadSuccess (returnedValue:Object) {}
    Alert.Show (returnedValue.toString ());
    }
    private void wasFailure (failed: Object) {}
    Alert.Show (failure.toString)
    }

    Then the server about...
    MyFunc = function () {}
    return "it worked."
    }

    The server is called and then it is called the machine successfully, but there is never any return value. What Miss me?

    I thought about it. Thought the problem seemed familiar. Pulled my hair out on this one before as well.

    But... I'll post the solution because I know I'll get the same answer again in a month;).

    In the FMS, I use components. When the client is added to the component, it implements the proxy/path to receive calls from the client.

    i.e.
    {myComponent.prototype.addClient (client)
    [.. Snip...]
    myproxy.someCallFromClient = function (var1, var2) {}
    this.mySomeCallFromClient (var1, var2);
    }
    [.. Snip...]
    }
    myComponent.prototype.mySomeCallFromClient (var1, var2) {}
    return "Hello Word";
    }

    See what I'm missing? Yah I'm still missing too...

    myproxy.someCallFromClient = function (var1, var2) {}
    RETURN * this.mySomeCallFromClient (var1, var2);
    }

    Always forget to add back to the proxy in the addclient! Grrr...
