Memory system cache on windows server 2003 standard 64-bit is too hign

Hi,
I have an issue with one of the server - OS is windows 2003 standard 64 bit. Total memory installed on the server is 16GB. When I go to task manager>performance tab, Total physical memory is 16 GB, available memory is around 500 MB almost all the time,
System cache is greater than 13.5GB. When I take a look at all the processes that are running, and if I sum those memory usage it will be around 2 GB. So all the memory is consumed by system cache. Checked the perfmon > memory> system cache resident
bytes and it is showing greater than 13.5 GB. I have gone through some articles that tells me to use RAMMAP to find which is using more system cache. But RAMMAP is not designed to run with windows 2003 version. Please can you help with a way/tool to find what
is using system cache in windows 2003 server
Thanks in advance

It is supposed to do this. Windows can be very aggressive in caching data and code. This data is released as soon as the system needs memory for something else, but when it is unused, the system uses it to cache all sorts of stuff. It utilizes the memory
which would otherwise be unused. Leaving it unused would basically be a waste.
So in other words, nothing is wrong. It is windows which decides to try and be more efficient. As soon as a request for more memory comes in, it just drops whatever is needed from the cache immediately.
This is one of the reasons that in later versions, the memory is reported differently in task manager, because people kept trying to stop the system from caching because they wanted to see more 'free' memory.

  • Windows server 2003 Standard edition RAM Upgrade

    We are using Windows server 2003 Standard 32 bit edition in our office With HP ProLiant DL580 Generation 5 hardware , We are trying to upgrade RAM to 8 GB from 4 GB but it is not taking, It is detecting 8 GB RAM while booting but not showing in my computer
    property. 
    Same thing we tried with Windows server 2003 Enterprise edition and it is working fine there.
    Is there anyway to upgrade it ?

    It is normal. You simply need to use a 64 bit OS.
    You need to re-install the OS to be running a 64bit version as no in-place upgrade is supported.

  • Oracle 10g on Windows Server 2003 Standard 64bit

    We are running Oracle 10g on Windows Server 2003 Standard 64bit Edition. I am NOT a DBA, so forgive my ignorance.
    We have 16GB of physical memory in this server. I was told by a DBA that Oracle runs on "a single process", and because of that, he said that Windows Server 2003 Standard will only allow 2GB max for a single process.
    Can anyone confirm this? Thanks.

    This sounds more lika a Windows issue. If both Windows and app is "64-bit", I would expect the user virtual address space (per process) to be in the TiB range, if not larger.
    (The said 2GiB limit applies to a 32-bit system.)

  • Issues when Sharepoint Services 3.0 OS upgraded from windows server 2003 standard to windows server 2003 enterprise

    In my sharepoint 2007, I have upgraded the OS from windows server 2003 standard to windows server 2003 enterprise R2 SP2. After the OS upgrade when I run the central admin it's showing this error "Microsoft Windows Sharepoint Services 3.0 Error 2908
    error has occurred" screen shot below of the error. 
    Any help?

    Not sure I can help.  In general MS does NOT support the upgrade of the Underlying OS without re-installing SharePoint.  Many of the prerequisites that were installed when SharePoint was installed are OS specific.  You can either contact
    Product Support and see if they can provide any assistance or re-install SharePoint from scratch and re-attach/migrate all the existing databases with content into the new system on the new OS.

  • Is there a limit for SGA_MAX_SIZE on windows Server 2003 Standard Edition

    I have a 9.2.0.8 Standard Edition running on windows Server 2003 Standard Edition. I cannot set SGA_MAX_SIZE to more than 1.7G. I have total of 3G RAM on that machine.

    In order to use memory over 4 GB the /PAE flag must be set and Oracle must be tuned
    accordingly. As mentioned above, for using memory over 4 GB and less than 16 GB, the
    /3GB flag can be set as well. Oracle uses memory above 4 GB by taking advantage of
    the AWE (Address Windowing Extension) feature built into Windows 2000, Windows
    2003 and Windows XP.
    In order to use this memory, the Oracle administrator account (either LocalSystem or the
    domain user that installed Oracle) must have the “Lock memory pages” privilege set. In
    addition the AWE_WINDOW_MEMORY parameter must also be created and set. This
    parameter specifies how much of the 3 GB virtual memory space allocated to Oracle
    should be used for mapping database buffers. The default value of 1GB should be
    sufficient and increasing this value could be detrimental, since you only have 3 GB of
    virtual memory to use. The higher the value of AWE_WINDOW_MEMORY that you
    have set, the more likely it is that you will experience user memory issues. Start with the
    default value of 1 GB and tune upwards only if you need to.
    Once these steps have been completed, larger memory can be set by configuring
    DB_BLOCK_SIZE and DB_BLOCK_BUFFERS initialization parameters. When using
    Very Large Memory (VLM) you should use DB_BLOCK_BUFFERS rather than
    DB_CACHE_SIZE in order to configure memory.

    Hi:
    Not the usual thing in forums to use all caps, but no offense taken.
    For password reset, try this:

  • Installing CF9 on Windows Server 2008 Standard 64-bit

    Hi-
    I'm attempting to  install a new ColdFusion configuration with a host who is useless  regarding the support that they offer (for now, they shall remain  nameless).
    It's a Windows Server 2008 Standard 64 bit VPS  configuration. MySQL is already installed so I'm on the hook to  configure ColdFusion 9 with IIS (7.5, I believe). There are numerous  settings which the installer does not seem to address so I've had to  address several Module Mappings which failed during the install....
    Can  anyone point me to an installation doc for the above configuration?  Will the CF installer eventually handle these issues or are we on our  own to support this?
    Thanks in advance,
    Rich

    My advice is to get out now and go to a site like hosting.com that has a solid track record hosting CF. There are several others to choose from. If they are starting this rough you will have constant problems.

  • System Refresh On Windows Server 2003 ( Oracle )

    Hello Gurus,
    We are having ecc5.0 production server on windows 2003 server ( oracle as an database ).
    We want to perform system copy.
    can somebody guide me the procedure on windows server.
    Server Information
    ECC - 5.0
    Window Server - 2003
    Oracle ( 9.2.0.8.0)
    I have one doubt should we use SAPinst for export/import procedure or backup restore from our production server to dev server  
    regards
    Shishir

    Hi Shishir,
    I have one doubt should we use SAPinst for export/import procedure or backup restore from our production server to dev server
    DEV System is your original System never refresh DEV System with Production. It is recommended to do System refresh on QA system or any other stand alone system (Test System).
    Also see the below points.
    1. If you have large database then use the backup restore process. this will help you to reduce your downtime.
    2. You can go for the export/import process i.e R3load using SAPinst.
    For more information see the system copy guide as suggested earlier.
    Thanks,

  • Running 10G as a non local system account on Windows Server 2003

    Hi,
    I have an Oracle 10G database running on Windows Server 2003, SP2. I have created the database and it all works fine while the service is running as the default local system account. However, when I change the user that the service runs as to a different account the database starts and opens, and I can log on as SYS using a bequeath connection but I am unable to log on as any other user going through the listener. The listener responds to TNSpings, and all seems to be OK. When I switch it back to the local system user again it all works fine.
    Can anyone offer any advice or help?
    Thanks,
    Rob

    That's probably because the listener is still running as the local system account. Have you tried to change the listener service to run as the same account as the Oracle service?

  • More than one SAP systems on same Windows Server 2003 - Oracle 10g

    Hello Experts,
    We have Windows Server 2003 with 32 GB RAM, 2 quadcore CPU, plenty of space. Already running with NW 700 AS Java on Oracle 10g.
    Now we need to install a seperate NW 700 AS Java central instance - so please help me in clarifying following doubts - we don't want to use MCOD.
    1. Do we need to install Oracle 10g software again or we can use the existing Oracle 10g installed files. If yes then will the Oracle Home for both the SAP instances will be same - any steps needs to be done for that.
    2. Any other steps which needs to be taken care before and after the second instance installation.
    3.SAP Note 98252 - speaks about changes in oraInst.loc before the second instance installation - Does it applicable for Windows - Oracle environment also. I am not able to find out this file.
    Listener and Tnsnames file changes mentioned in this note seems to be applicable on windows platform also.
    Pointers to related documentation would be highly appreciated.
    Thanks

    Hello Davinder,
    > 1. Do we need to install Oracle 10g software again or we can use the existing Oracle 10g installed files. If yes then will the Oracle Home for both the SAP instances will be same - any steps needs to be done for that
    Theoretical you can use the same ORACLE_HOME, but i would really recommend to install the database software again in a different ORACLE_HOME. It will make a lot of things easier
    > 2. Any other steps which needs to be taken care before and after the second instance installation.
    The same as by the first installation, but keep in mind of the listener port - you will need to specify a different one.
    > Does it applicable for Windows - Oracle environment also. I am not able to find out this file.
    On windows it is a registry key (for more information please take a look at metalink note #564192.1)

  • Msi K9N2 Platinum SLI and Windows Server 2003 r2 32 bit edition

    Does anyone know or have tried to get this board to work on server 2003 32 bit edition. I seem to get past the raid part but the realtek 8211bl and audio are giving me fits. Any links to good drivers would be appreciated.
    Spec of system:
    Amd 9950 Quad
    4 gig memory
    Msi K9N2 Platinum SLI
    2 500 gig sata

    Ok overall solution this board works awesome with Windows Server 2003 Enterprise R2 with Sp 2.
    Here are a few tricks for the Co processor controller, Sm Bus, Audio and finally the networking controller.
    When you finally get windows loaded. Make sure you put Service Pack 2 or 3 on before u install drivers.
    The raid drivers are simple for the 32 bit version use the xp ones and load both raid drivers during setup. Requires 2 floppys or Slipstream disk.
    http://global.msi.com.tw/index.php?func=driverfile&dno=7067&i=2
    Once you get windows loaded and Sp 2 or better on. Stick in your windows vista driver disk in. Once there do not install anything.
    Goto device manager and update drivers on all that are with the yellow ? excpet the networking drivers and just do an automatic search and boom your done. It will also ask you if you want to enable your audio at this time. Do so but do not reboot untill u finish installing all drivers but networking. Than reboot pc
    Last part is for networking card. We need you to be in safe mode for this. So once u install all drivers and start reboot hit F8 and goto safe mode. Once in safe mode take out vista driver disk and put in xp driver disk. Goto device manager and update driver on network controller and let it do an automatic search and it will installl it. It will say it needs to be rebooted to work. Go ahead and reboot and your networking card will work.
    Probably simpliar solution. But just wanted to give my help.
