Does JDK 1.5 support hugepages on Linux

JRockit JVM has the facility by which it uses hugepages if available to store its heap within the Linux kernel. I am trying to find a similar facility within Sun's JDK 1.5. Any clues?
Thanks
rh

The JDK has had large page support on Solaris for many releases but it is relatively new on Linux. There are a few issues with some older kernels and the feature is disabled by default. The -XX:+UseLargePage option is used to enable it. To use this option you need to be using 5.0u5 (just released), or a mustang (Java SE 6.0) build.

  • Does JDK (java development kit) already comes installed on the Macbook?

    Does JDK (java development kit) already comes installed on the Macbook?
    I was at the Oracle website and noticed they have a JDK version for Windows, Linux and Solaris, but I couldn't find one for Mac OS. How is possible to develop in Java if you are using a Mac? Does the JDK already comes with it?

    No.

  • Does the 6600GT-VTD128 support video capture?

    Hi,
    I recently purchased an MSI 6600GT-VTD128 video card.  The product information seems to suggest that the card has video input capabilities, and there is an adapter that plugs into the card that has a number of connections, one of which is labeled S-Video in.  However, I haven't been able to get any video capture to work.
    Does the card actually support this functionality?  If not, what are the video input connections for?  If so, is there some documentation as to how to set it up?  
    So far, I tried installing the video capture drivers that come with the card.  I checked the manual.  I checked the MSI web site FAQs.  And I searched the forums.
    Any help would be greatly appreciated.
    Thanks,
    Daniel

    Thanks Richard.  Yes I do have a breakout cable like that.  Actually, I described it in my original message.  So, I am guessing from your message that you believe that the card should have the capability to capture video.  
    In my original message, I asked if there was any documentation on setting up the card for video capture.  The manual does not describe the procedure, nor does the MSI web site.  
    There are drivers on the CD that claim to be for video capture, but they had no effect when I installed them.  In fact, there appears to be no way to tell whether the drivers were actually installed successfully.
    If anyone out there has successfully used this card for video capture, please let me know.

  • Does Sender Mail Adapter support "PayloadZipBean" module

    Hi everyone,
    I have a scenario where, I get the email with an zip file as an attachment and I need to extract this file and send across. There is no mapping transformation done here, only I need to forward the attached file to the file server.
    Zip file always contains 1 file and is a text file.
    so Its an Email to File Scenario.
    Can I send the zip file as it is without unzipping i.e., send the attachment as iit is to the file server?
    If I want to unzip the file, does the module "PayloadZipBean" support in case of sender mail adapter. ?
    Thanks,
    Varun

    Hi Varun,
    Use "PayloadZipBean " Module at Receiver Communication Channel  in the Module Tab Set the "Module Key.mode =  unzip"
    and Receiver communication Channel file should be "FileName.txt".

  • Get an Error window, The source folder does not contain any supported camera raw files

    I am using CS2 and it would not open up my latest RAW files, I was getting a warning Could not complete your request because it is not the right kinds of document. So, I checked the Camera Raw Plug-in and it says Version 3.7. I see that my camera an Olympus E-20 is supported. But it is not opening the Raw files, the day before I took jpeg and they have opened. I will not trash my Adobe Photoshop CS2 because it was a royal pain to install and I don't know where the CD is.
    I installed the latest DNG Converter and when I try to open up the folder which has all the RAW images that didn't open in Adobe, I still get an Error window that says, "The source folder does not contain any supported camera raw files." Why? It says it supports my Olympus E-20. I actually have the E-20n, I don't think that is the problem. My RAW icons usually show up as small image thumbnails and this time they are gray icons only with the incorrect date under the icon. Is there another product I can use without spending money? These images I took in RAW were special and I don't want to lose them. Please help!
    Esther

    Hello, I was using only CS2 with my Olympus E-20n for 5 years, no problem. It just started acting up in RAW this year. I downloaded Picasa that same day and now it seems to be opening up all of my RAW files that didn't open the other day. So, I think Picasa installed a new plug-in adaption to CS2 because now all my RAW icons have a new logo on them, the same one that's in Picasa. Strange, but it works now and I am not complaining anymore. I love CS2 and the many ways I can adjust RAW files, so I am using it, Picasa is a sideline now that I can take a look at many thumbnails and it organized all my photo files by the year and folders. Amazing free software. I have probably 60,000 images in my computer and an external hard drive and Picasa picked them all up and made a library, cool.

  • Does 10.5.6 Support Dual displays for Radeon 9800 Pro Mac Edition cards?

    Does 10.5.6 Support Dual displays for Radeon 9800 Pro Mac Edition cards?
    And is there driver updates for anyone using the all-in-ones HP printers...has anyone been able to use their scanners since the update? and has the dual screen support been added to avoid the blue screen on startup?

    The ATI Radeon 9600 PC/Mac edition 256 MB should work in the MDD G4. It has two DVI ports (one is dual-link and can support a 30" display). You will need adapters for ADC displays.

  • What versions of Xerces-J and Xalan-J does JDK 1.5 make use of

    Can any one tell me what versions of Xerces-J and Xalan-J does JDK 1.5 make use of.

    Hi all,
    I have a class which has a Vector<Vector> data
    member.
    I expect its collection to contain more collections
    hence the Vector<Vector> type.Everything is OK with your concept, except that you just declared a variable of type "Vector of Vectors". Instead, you need to declare it as "Vector of Vector of Objects":
    private Vector<Vector<Object>> coll;and initialize it with
    coll= new Vector<Vector<Object>>();

  • Is JavaMail 1.3.3 supported on z/Linux platform

    Hi, I would like to know are following libraries supported on z/Linux platform ?
    1) JavaMail 1.3.3 and
    2) Java Activation Framework 1.0.2
    Or can you please send me the known issues, if any ?
    Also would appreciate if could send me any info/link for 64 bit JVM support for these.
    Thanks a lot in advance / Rajan Kumar

    Java is supposed to be Write Once Run Anywhere. So I would assume that ordinary Java code would run on z/Linux, 64-bit or otherwise, until my tests proved otherwise.

    It's the default sort order. You can choose chronological order( ascending or descending) or by Import batch or by filename. Contrary to older versions, those sort orders are available not only in thumbnail view, but also in Folders view and albums. In albums you can sort as you like 'custom order'. No difference in Mac or Win.
