64-bit JRockit on Windows for EM64T

When will be available for download a version of 64-bit JRockit, which has support for Windows on 64-bit Intel Xeon processors (EM64T)?
Or, is it possible to download any beta for it?

It will be available for download within a month. Unfortunately, we do not have a public beta.
Cheers,

  • 32Bit Eclipse, 32Bit JRockit, 64Bit Windows OS - Maximum  Heap Space.

    Hi:
    My 32Bit Eclipse application tends to run out of heap space on big files. I have been using Sun JRE 6. JVM.
    Using the Sun JRE 6 JVM the maximum heap size I can achieve is 1.3GB
    My machine has 8GB of physical memory.
    I'm wondering if there is any advantage in moving to JRockit.
    1. Willl the 32Bit JRocket JVM enable me to have more heap space on 64Bit Windows XP.
    2. If (1) is possible what are some aggressive settings I can use to maxmiise heap space.
    Thanks
    Mark

    We run 2.75 GB ( -jrockit -Xms2816m -Xmx2816m ) in production all the time with 32-bit JRockit on Windows 2003 Server 64-bit. I had hoped to get it to 3.25 GB, but we occasionally run out of native memory and have to back down the heap size to 2.75 GB. I look into it when I get more time. Remember to set your min and max memory equal.
    The max your process can consume is 4GB (max addressable memory with 32-bits), so your JVM memory + Heap memory can't go over 4GB. If you use JRockit Mission Control, you can connect to the JVM and monitor the size of your virtual address space (looking at Mem Usage in Windows Task Manager kind of works too). I'd start with these JVM args:
    +(all args should be on one line)+
    -jrockit -Xms2816m -Xmx2816m
    -Xmanagement:ssl=false,authenticate=false,port=7091
    Connect to it with the jrmc.exe program in your JRockit bin directory and you can get a pretty good idea what is happening in the JVM. Also, if you haven't already, download the latest JRockit (google: JRockit download).
    Hope that gets you started so you can check out JRockit...

  • Mission Control for EM64T JRockit R27.3.1.1.5_11 (64bit)

    Does the JRockit EM64T R27.3.1.x (64bit) release not come with Mission Control? I have it in our 32-bit R273.1.x release but not in the 64bit version.

    The JRMC GUI is only bundled with the 32-bit JDKs for Windows and Linux, plus the 64-bit JDK for Linux EM64T. The reason for this is that it is built on the Eclipse RCP, and that toolkit is not available in a stable version for 64-bit Windows EM64T.
    The server side portion of JRMC is built into JRockit, so you can use the GUI from a 32-bit JRockit JDK to connect to any version of JRockit on any platform.

  • Any hope of getting 64 bit twain plug in for Windows 64 bit Photoshop

    Just what the title sez: any hope of getting 64 bit twain plug in for Windows 64 bit Photoshop? Frustrating to upgrade and have to do a work around to use your scanner. Will Adobe release this?

    Chris,
    I have a CanoScan 8800F plus CS5, both 32-bit and 64-bit versions installed. When I scan four slides in a holder, the 32-bit TWAIN driver/plugin gives me four images of one slide each. The 64-bit WIA driver/plugin gives me one image of the slide holder, with the four slides in it. Is this a limitation of the WIA technique in general or the particular WIA driver for my CanoScan?
    Best regards,
    Antero

  • HT204406 Please help!  I have downloaded the 64 bit version of iTunes for my Sony running WIndows 8.  I have iTunes running on 3 other machines (MACs) with no issue.  On the Sony with WIndowns everytime I turn on ITunes Match WIndows fails, everything shu

    I Have downloaded the 64 bit version of iTunes for my Sony running Windows 8.  Install went fine and I can get in to iTunes and see the music residing on this machine.  However, everytime that I try to run iTunes Match Windows crashes.  So frustrating.  BTW, this worked fine until a couple of weeks ago.  Anyone know what's going on?

    How big is your library?  I would recommend the following troubleshooting steps:
    - Backup your library.  Always a good idea before messing with things.  
    - Create a new library.   Refer to this article for details:  http://support.apple.com/kb/HT1589.  This won't delete your old library, you're just creating a new empty one.  Also refer to this article to get back to your old library later.
    - Add a few albums into this new library.  Not everything, just a small sampling, as a test.
    - Activate Match on this new library.  You shouldn't have to re-pay, it should just say "Add Computer" or similar.
    - At this point, Match should run again. With just a few albums it should complete in just a few minutes.
    If iTunes doesn't crash at this point, then likely there's something about your original library that Match doesn't like - what that is I don't know, but at least you'll know it's not your PC.   If iTunes still crashes, then if could be a number of other things, but probably not your library.   My next suggestion (if you haven't already done this) is to uninstall / reinstall iTunes.   If that doesn't work, then my next ideas you won't like.   

  • Why is there no Boot Camp support for the 64-bit version of Windows 7 on the 64-bit iMac that I'm using?

    The early 2008 24" iMac 8,1 has a 2.8 ghz E8235 Intel Core 2 Duo processor with a data width of 64-bits.
    I am straining badly to understand why Apple is only providing drivers for the 32-bit version of Windows 7 for the 64-bit hardware that I want to install it on.

    The 64 bit drivers are there, but there have been some installation
    issues depending on Windows OS and Apple hardware.  You may
    want to post on the Bootcamp forum to get more direct response to
    your issue.
    FWIW, at one point, I forget when, I found I needed to manually
    open the 64 bit versions of the drivers to install them that were created
    on the bootcamp driver install disk (image).  As I recall the was a
    64 bit .msi "global" installer but even at that there was an individual
    one that needed to be manually installed.
    Its been a while since I last did this since I have been doing everything
    in Windows virtual machines with Parallels.

  • How do I download the 64-Bit version of iTunes for Windows 7?

    I just got a new computer with Windows 7 O.S. I have downloaded the latest version of iTunes to the computer, but when I try to install it, I am getting a message telling me I need the 64-Bit version, but I have downloaded the 32-Bit version.
    I have tried to find the 64-bit version but am having no luck finding it. Can someone please point me in the right direction with a link to the 64-Bit version. Thank you very much.
    Joie

    Head to the downloads page, Joie:
    http://www.apple.com/itunes/download/
    Down at the bottom left (scroll down if necessary?), you should see:
    64-bit editions of Windows Vista or Windows 7 require the iTunes 64-bit installer
    ... click the *64-bit installer* text to go to a downloads page for the latest version of the 64-bit installer.

  • Some performance counter objects are not available for a 32-bit process on 64-bit versions of Windows Server 2012 standard

    When we try to gather performance counter information for a 32-bit process on a 64-bit computer that is running Microsoft Windows Server 2012, all our performance counter objects are not available with 32 bit perfmon application (C:\Windows\SysWOW64\perfmon.exe)
    I didn't notified any errors while registering our counter objects or while running Perfmon.exe
    Note: Same counter objects are available and working fine with Windows Server 2008 R2.
    for diagnostic our counters on WIN2012, ran command as follows:
     cd c:\windows\sysWOW64
     lodctr /Q
    I am able to see all our counter objects on response and infact all were shown as enabled, as shown below
    Appreciate quiclk response with solution or clues to diagnose it more details.
    Thanks & Regards,
    Sudhakar Rudra

    Hi,
    Thanks for your reply.
    I hope you understood our problem.
    same our system counter objects (ver x), we able to browse from Perfmon 32 bit app on Windows 7, Windows 2008 R2 (64bit) OS but not on Windows 2012.
    I am able to see all counter objects registered as follows (same at HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\HMI Alarm Class\Performance,
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\HMI Alarm Class\Performance
    and
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HMI Alarm Class\Performance)
    Only difference I observed that "Disable Performance Counters" were set to 4 in Windows 2012 OS unlike other windows 7 64bit OS and there is no differnece for remaining all entires.
    I tried setting that "Disable Performance Counters" value to "0", but some how they get reset to "4", no luck..
    I think "Disable Performance Counters" value either "0", or "4", should not matter for browsing our counters with 32bit bit perfmon applicaiton.
    Do you see any issues of registry entries. ?
    On what basis perfomance monitor list few enabled counters?
    How can we add our counters manually to perfomance monitor?

  • 64-bit version of Quicktime for Windows

    I'm running 64-bit version of Windows 7 via bootcamp.  I'm running 64-bit version of Microsoft Office 2010.  I have the latest version of Quicktime installed 7.7.3 something.  I can play the file on the desktop no problem, but when I try to insert the file into Powerpoint or play a file that I inserted previously into Powerpoint on a different system, it says either Quicktime unavailable or you need a 64-bit version of Quicktime in order to insert the file. 
    So, exactly where is a 64-bit version of Quicktime for Windows because apparently the one on the Apple website for Windows is not 64-bit.  Everyone keeps saying download the 64-bit version of Quicktime.  Great, tell me where it is.  There is no option for 64-bit on the website.  It doesn't even say it is 64-bit.  It just says its compatible with Windows 7.  Powerpoint 2010 64-bit MUST have a 64-bit version of Quicktime in order to insert or play any Quicktime file.  The OS doesn't give a rats @ss one way or the other.
    The file I previously inserted was playing on a system that apparently had a 32-bit version of Powerpoint installed.  That machine defaults to VLC player on the desktop.  It has no issues with the file.  It's the Quicktime Player mismatch on my machine that is giving me grief.  If I knew Office was going to be a PITA if I installed the 64-bit version I would have stuck with the 32-bit version.
    Ideas?  Where is the 64-bit version?  How do you tell it is 64-bit?  How do you force the installer to make sure it ONLY installs a 64-bit version of it?

    If Microsoft merely off their own decided that only a 64-bit version of QuickTime was going to be supported by them and did not both checking such a beast existed then this is perfectly believable behavior on the part of Microsoft and they should roast in **** for it.
    If Apple led Microsoft to believe that a 64-bit version of QuickTime was going to be released like a 64-bit version of iTunes for Windows has been released but then backed out then this is equally believeable behaviour on the part of Apple and then equally the guilty parties at Apple should roast in ****.
    It should be noted that the 64-bit version of iTunes is able to play videos via the 32-bit version of QuickTime. This suggests Microsoft programmers are weak with the force. This would tend to support my theory that Microsoft despite being the biggest software company in the world are better at making hardware than software.
    Moving on to trying to be more constructive…
    Clearly as things stand using the existing and only official version of QuickTime for Windows which is 32-bit only is not going to work in 64-bit Office. It might therefore be worth looking at trying the following.
    Uninstall completely Apple's 32-bit QuickTime for Windows (if installed currently)
    Install QuickTime Alternative - see http://www.free-codecs.com/download/QuickTime_Alternative.htm
    I have no idea if QuickTime Alternative is 64-bit, I have no idea if it will work in 64-bit Office even if it is 64-bit. However it does work in Internet Explorer for Windows, it is free and therefore will cost you nothing to try. If it does not work you can then always uninstall it.
    As another even more abtruse solution, you could try loading your PowerPoint file in to the free iWorks i.e. KeyNote via a free iCloud account. It will allow importing PowerPoint files and will even work in Internet Explorer.

  • Windows 8.1, iOS 8.1.3, Itunes 12.1 64 bit, constantly get 'waiting for changes to apply' when trying to sync my new ipod touch

    Windows 8.1, iOS 8.1.3, Itunes 12.1 64 bit, constantly get 'waiting for changes to apply' when trying to sync my new ipod touch. Downloaded latest version f itunes, and ipod software up to date. Really frustrated I can't sync my music! Please can someone help me

    Im having huge issues after updating to 12.1 on Win 8.1  x64. Choppy playback and so on.
    Try this since it helps in most situtation :
    Remove itunes but keep library files. Then download it again and install it.
    Also most likely you will have to restore ipod touch. I restored my iPhone 5 to remove waiting for changes to apply and Error 54.
    my iPad air still isnt restored (cant do it now) and it sometimes does same like iPhone waiting for changes to apply. And gives error 54 but sync DOES GET COMPLETED.
    Also may sound stupid but try to use USB 2.0 Ports. Not 3.0. I have troubles when using 3.0

  • ITunes: Installer is indented for a 32-bit version of windows. Please obtain a 64 bit installer

    I get this error message when installing the itunes64Setup.
    Installer is indented for a 32-bit version of windows. Please obtain a 64 bit installer from www.apple.com/support.
    Originally ,I copied my old 32bit files from Vista to a new windows 7 machine and then I  tried to reinstall iTunes  and got the error message.
    In addition, i tried to uninstall iTunes and it will not uninstall. Then I tried to clean it off manually and reinstall it. I still get the same message Installer is indented for a 32-bit version.
    Any suggestions.

    64bit architecture is a bit tricky, particularly when it comes to hardware. While I'm fairly sure Apple (like a lot of other companies) will work to support this in the future, the fact is that folks running 64bit right now are in a huge minority (less than 1/10 of a percent) and it's impossible to support everybody.
    There are probably about 10 times the number of folks running some version of Linux on their PCs (we're not talking Macs here right now) and yet they can't use the iPhone or a whole lot of other things. It's just the way of thw world -- pick something that isn't mainstream and you pay for being on the bleeding edge.
    It will catch up to you -- patience is indeed the key.

  • When will Apple develop a 64 bit version of Safari for Windows?

    I've been using this browser for a while now and absolutely love it!
    Features that stand out from the crowd are:
    Apples unique font smoothing technology.
    Best colour management available on any browser.
    Speed.
    Excellent web standards coverage.
    Most of the competitors are now developing 64 bit versions in preparation for the release of 64 bit Flash and Silverlight. Apple cites improvements for it's Mac OS version 64bit vs the 32 bit. If development isn't in the works then it should be for Windows!
