Maximum Memory Size & Memory Size

Will a server's memory automatically increase from Memory Size to Maximum Memory Size as the VM requires it? Or is this only valid for adding memory to the Memory Size value manually?

The max memory size just specifies the maximum amount to which you can manually adjust the memory of a running VM. I've now taken to setting the max memory size to the total available memory on my Oracle VM Servers, with memory size set to something reasonable. This way, I can adjust right up to the limit of physical memory without rebooting.

  • Maximum file size in picture ring?

    Hello folks!
    I am planing to use a picture ring with a quite big amount of data needed.
    My question: is there a maximum data size that i can embed in a picture ring (number of pictures or overall file sizes)?
    Thanks!

    If you have enough memory to keep all the images open simultaneously, then something like this might help.  Put all your images in the same directory on disk and have no other files in that directory. Then use List Folder from the Advanced File palette to get an aaray of the filenames.  Feed that array to a for loop where you open all the files and place the images into the pict ring.  I have written a "slide show" program which does this. Never tried it with 400 images though.
    If you do not have enough memory for all the images, then you need to manage the iamges much more carefully.

  • Maximum file size exceeded?

    Recently I've bought curve 9300 - so far it looks to be the best phoned I had so far.
    But yesterday I finally decided to install desktop software and check some other functions of the phone. And that's when I found a problem. I haven't installed ny media card, but there's some free space showing on the built memory. I've wanted to upload a couple of multimedia files ( .mp3 - using "file" button, I'm not using Itunes, Windows media etc) . I got an info that maximum allowed file size has been exceeded (I'm not sure it's excat phrase as I had to translate it from Polish). What's wrong? I'm pretty darn sure that file I wanted to upload is smaller than free space (mp3 of around 5MB).

    Hi and Welcome to the Community!
    Here is a KB that discusses that error:
    KB26221 "File exceeds the maximum file size of the destination or is too large for the system" appears when saving attachment files on the BlackBerry smartphone
    Hopefully it contains something useful! While it is written for the 9700, I suspect it applies to your BB as well.
    Good luck and let us know!

  • Maximum file size that OSB can handle for JMS

    Hi,
    We have a requirement to process 60MB xml files over JMS in Oracle Service Bus. While prototyping this we are facing heap space errors.
    Can somebody let me know what is the maximum file size that we can process? The scenario is as below.
    JMS --> OSB --> JMS --> OSB --> JMS
    Thanks

    if you don't need to access the entire content of the message, you can try using content streaming
    (see this OSB - Iterating over large XML files with content streaming discussion)
    See also here http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1110513 for best practices.
    Otherwise I have noticed myself that OSB is very hungry in memory when loading large messages. I had trouble even with a 5 MB binary file being loaded - this would take 500 MB RAM. in these cases I would rather look for ETL tools such as Oracle Data Integrator or Open Source Pentaho.

  • Maximum heap size for 64bit JVM

    where is this limitation coming from. How to set the heap size to 6g.

    You need to use the -d64 switch to request the 64-bit JVM. E.g.,$ java -showversion -Xmx6g HelloWorld
    Invalid maximum heap size: -Xmx6g
    The specified size exceeds the maximum representable size.
    Could not create the Java virtual machine.

  • How to set the maximum heap size on a deployed application?

    I�m running a fairly large java application and am getting java.lang.OutOfMemoryError. I could increase the heap size in my development environment to eliminate this error. However, I don�t know how to set this in a deployed application. We are currently using ant to build our software.
    Another question, when I execute a statement such as java �Xmx512M �cp app.jar. Is it correct to say that the application in app.jar will use to a maximum of 512MB of memory when running?
    Thank you everyone for your help!

    But first, when you say "a deployed environment" do you mean an executable .jar file? This is what I'm using.The term "deploy" is commonly used to refer to deploying an ear file or a war file on an application server.
    I would assume that there is some entry you can include in the .jar's
    Manifest.mf file to specify the maximum memory, but I can't find an example of the entry. <a href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6197671"></a>

  • Maximum Character size of Front Panel indicator in LabVIEW

    Hi,
    I have a simple question that I hope somebody can answer.  Is there a maximum character size that can be displayed in a Front Panel indicator in LabVIEW?  If so, what is it?  I have a VI that is continuously reading a serial port and updating a front panel indicator, and I need to know how much text can be displayed before it either truncates or throws an error.  This is for LabVIEW 2010 SP1.
    Thank you,
    J Korn

    A quick Flatten to string shows how LabVIEW stores strings {size-data} Size is a U32 so 4294967295 characters max.
    The big thing to remember is this memory must be contiguous (and the Indicator requires a COPY) so in practice the performance hit for constantly allocating larger and larger buffers for the data and available memory impose practical limits much lower than the 4294967295 Char maximum.  Probably better to log the data to a file and maintain only the last x characters on the indicator and use the file to look a history data

  • Upto how much I can set maximum Heap size for jvm?

    I am running application on 8GB RAM Windows 64 bits machine.
    I am running out of OutOfMemory (Heap Space). I want to increase the Heap Size for my jvm.
    But can anybody please tell me what is the limit by which I can set the maximum size for heap?
    Thanks in Advance,
    Jenish

    Max allowed memory per process is 2 raised to the 64th power. What maximum memory you can set depends on the memory available
    for your application. You may be able to set more than 8GB ram then it will use the swap space and it will slow down your application
    performance. So try different memory size and see which one works best for your application.

  • Is there a default maximum memory allocation ?

    Hi,
    I would like to ask if there is a default maximum memory allocation in the virtual machine?
    I know there are params for setting the initial und maximum size but I'm not sure if the vm will take as much memory as I have in my computer or not.
    thanks
    guenter

    Hi guenter
    Are you looking for the -Xmx parameter?
    According to the below link, the default maximum is 64MB

  • Is there a problem with maximum RAM size for Satellite 320CDT?

    I have a Satellite 320CDT with the latest BIOS (v8.00) and Windows 98 SE installed; there is 32MB base memory and a 32MB module in the single expansion slot. If I change this for a 64MB expansion module I can still only see 64MB total memory reported, not 96MB as expected; the spec for the machine states that the maximum allowable memory is 160MB (32MB base + 128MB expansion). Does anybody know if there is a problem with the maximum memory size for this model and whether there is a solution or workaround? I need to know quickly, in order to decide if I need to return the memory module to the supplier! Many thanks for any help, Peter

    Are you certain you tried the correct type of memory module? It sounds like you're maybe trying to fit an incompatible type.
    There's a few different suppliers below.

  • Maximum Message Size

    Hi,
              I have had to increase the Maximum Message Size on each of several weblogic server instances from 10,000,000 bytes to 30,000,000 bytes. The upper limit for this value is 2,000,000,000 bytes.
              What are the performance implications for the other server instances when this field limit is increased?
              Does anyone have a recommended initial value for this?
              Any help would be greatly appreciated.
              Thanks.

    Hi,
              This maximum message size helps guard against a denial of service attack in which a caller attempts to force the server to allocate more memory than is available thereby keeping the server from responding quickly to other requests.
              Secure value is 10000000.
              Go through the following link and find the needfull information on this issue.

  • BIOS SETTING, need help! MAXIMUM PAYLOAD SIZE? NEO4 PLAT SLI

    Hi everyone, this is my first post here, and hope someone will help me out.  I've searched the internet, posted on other websites and no one can help me with this question.  What does MAXIMUM PAYLOAD SIZE do?  What is the correct setting for this?  Curruntly I have it at 4096, but what should it be at?  Thanks everyone.

    Thats a good one (question)... as far as I know it could be similar to the old AGP Aperture Size, but the amount of data doesn't correspond; megabytes vs. kilobytes.
    It could be the logical data unit which is carried thru the PCI-E bus in order to feed the PCI-E devices, this is sounds better yet again would be something similar to the AGP Aperture Size: not amount of data being mapped at physical memory, but the size of the data units being transfered.
    Hope this helps... try the values to either side and test with a 3d Benchmark, if you see a diference then come back and tell us.
    Good Luck.

  • Security Services \ Outbreak Filters - Maximum Message Size to Scan?

    We still have the Maximum Message Size to Scan: set to 256K is that too low by today's standards?

    We have our set to 1M.  The only issue is that it will use more memory to scan.  Other than that, no issues for us when we change it.

  • Maximum Step Size

    Hi BlueOne,
    we a have baseless rumor here at our department that says the maximum step size is 6000.
    I have just done a 2PowerX Copy paste with the statment type.
    I have stopped pasting after 8192 steps inside the sequnce
    and let it run. Works - perfekt as assumed!
    So just to clarify. Is the there a maxium step size?

    Juergen,
    i have not found any information confirming or contradicting this officially. Fact is, that (as your quick test proves as well) i am not aware of a limit of "number of steps per sequence" in any TestStand version.
    Granted, maybe there has been a limit in the past, but i doubt that.
    I think the rumor originates by memory issues when loading tons of code modules for different steps on start of an execution.....

  • Is there a maximum memory allocated?

    Dear all,
    Anyone knows if there's a limitation to the maximum memory
    that labview can allocate in Win98?
    I cannot allocate more than ~ 19500 KB and my computer has
    1GB.

    It seems it is a problem with the working set size and locking of pages. We have developed under Win2000 and have a double buffer daq application. The problem was the application was too late in the loop to get the data from the driver so it gets overwritten. Think of calling AI Read in a loop and the loop stopped for some time.
    I suppose you have no documentation for the windows API so I give you some from the MSDN.
    VirtualLock is the function which locks memory into RAM.
    "The VirtualLock function locks the specified region of the process's virtual address space into physical memory, ensuring that subsequent access to the region will not incur a page fault.
    All pages in the specified region must be committed. Memory protected with PAGE_NOACCESS cannot be locked.
    Locking pages into memory may degrade the performance of the system by reducing the available RAM and forcing the system to swap out other critical pages to the paging file. Each version of Windows has a limit on the maximum number of pages a process can lock. This limit is intentionally small to avoid severe performance degradation. Applications that need to lock larger numbers of pages must first call the SetProcessWorkingSetSize function to increase their minimum and maximum working set sizes. The maximum number of pages that a process can lock is equal to the number of pages in its minimum working set minus a small overhead.
    Pages that a process has locked remain in physical memory until the process unlocks them or terminates.
    To unlock a region of locked pages, use the VirtualUnlock function. Locked pages are automatically unlocked when the process terminates."
    The SetProcessWorkingSetSize functions allows you to get more locked memory.
    "The SetProcessWorkingSetSize function sets the minimum and maximum working set sizes for the specified process.
    The working set of a process is the set of memory pages currently visible to the process in physical RAM memory. These pages are resident and available for an application to use without triggering a page fault. The size of the working set of a process is specified in bytes. The minimum and maximum working set sizes affect the virtual memory paging behavior of a process.
    The working set of the specified process can be emptied by specifying the value -1 for both the minimum and maximum working set sizes.
    If the values of either dwMinimumWorkingSetSize or dwMaximumWorkingSetSize are greater than the process' current working set sizes, the specified process must have the SE_INC_BASE_PRIORITY_NAME privilege. Users in the Administrators and Power Users groups generally have this privilege. For more information about security privileges, see Privileges.
    The operating system allocates working set sizes on a first-come, first-served basis. For example, if an application successfully sets 40 megabytes as its minimum working set size on a 64-megabyte system, and a second application requests a 40-megabyte working set size, the operating system denies the second application's request.
    Using the SetProcessWorkingSetSize function to set an application's minimum and maximum working set sizes does not guarantee that the requested memory will be reserved, or that it will remain resident at all times. When the application is idle, or a low-memory situation causes a demand for memory, the operating system can reduce the application's working set. An application can use the VirtualLock function to lock ranges of the application's virtual address space in memory; however, that can potentially degrade the performance of the system.
    When you increase the working set size of an application, you are taking away physical memory from the rest of the system. This can degrade the performance of other applications and the system as a whole. It can also lead to failures of operations that require physical memory to be present; for example, creating processes, threads, and kernel pool. Thus, you must use the SetProcessWorkingSetSize function carefully. You must always consider the performance of the whole system when you are designing an application."
    But these functions will not be supported under Win98. I know from some other function which was stated to be not supported under Win98 were supported under Win98SE.
    But thats the time to get an answer from NI personal with more insight into what NIDAQ and the lvdaq.dll does.
