4gb file size limitation using java.io.* package in java stored procedure

Does anyone know about file size limitations when using java.io.* package inside java stored procedures. I have some java stored procedures that read and write to files. They error out when run as a java stored procedure within oracle on files over 4gb. I have no problems with these procedures when I test them outside of oracle.

I am using 10g Release 10.2.0.1.0, the java version returned by the Oracle JVM is 1.4.2_04
When I tested it outside of oracle I ran it using the java run time in ORACLE_HOME\jdk\bin and it works perfectly on files larger than 4gb.
Thank you for the UTL_FILE suggestion. I have considered using that but there is one method in Java that I can't seem to find a corresponding procedure for in PL/SQL.
RandomAccessFile.setLength()
This allows me to truncate a file. I have a need to strip bytes off the end of a file without creating a copy because I am working with large files and disk space may be limited. It is also much slower to read from the original file and writing the same bytes to a new file (minus the trailing bytes).
If anybody has any insight about the 4gb java.io limitation in Oracle JVM or has a workaround in PL/SQL for the RandomAccessFile.setLength() method in Java, I would really appreciate the help.
Thanks,
Thach

  • Is there a file size limitation to using this service?

    I am working on a large PDF file (26 mb) and I need to re-size the original and mess with the margins. I don't beleive there is an easy way to do this in Adobe Acrobat 6.0 Pro. It sounds like I have to convert the file back to a Word document, do the adjustments there and then produce a new PDF. I have two questions:
    Is there a file size limitation to using this service?
    Will a PDF to Word doc. conversion mantain the format of the orginal PDF?
    Thanks
    Tim

    Good day Tim,
    There is a 100MB file size limitation for submitting files to the ExportPDF service.  As for the quality of the conversion, from our FAQ entitled Will Adobe ExportPDF convert both text and formatting information?:
    Adobe ExportPDF is capable of exporting high quality information, but the quality of your Word or Excel document depends on the quality of the PDF file you start with. For instance, if your PDF file was originally authored in Microsoft Word or Excel and converted to PDF using the PDFMaker functionality of Adobe Acrobat®, your PDF file contains a rich set of information that can be captured by Adobe ExportPDF. This includes relative positioning of tables, images, and even multi-column text, as well as page, paragraph, and font attributes.
    If your PDF file was originally authored using simpler PDF generation methods, such as “print to PDF” or “scan to PDF” options, Adobe ExportPDF will convert any recognizable text and then use sophisticated conversion intelligence to preserve as much of the page layout as possible.
    Please let us know if you have any other questions!
    Kind regards,
    David

  • Nio ByteBuffer and memory-mapped file size limitation

    I have a question/issue regarding ByteBuffer and memory-mapped file size limitations. I recently started using NIO FileChannels and ByteBuffers to store and process buffers of binary data. Until now, the maximum individual ByteBuffer/memory-mapped file size I have needed to process was around 80MB.
    However, I need to now begin processing larger buffers of binary data from a new source. Initial testing with buffer sizes above 100MB result in IOExceptions (java.lang.OutOfMemoryError: Map failed).
    I am using 32bit Windows XP; 2GB of memory (typically 1.3 to 1.5GB free); Java version 1.6.0_03; with -Xmx set to 1280m. Decreasing the Java heap max size down 768m does result in the ability to memory map larger buffers to files, but never bigger than roughly 500MB. However, the application that uses this code contains other components that require the -xMx option to be set to 1280.
    The following simple code segment executed by itself will produce the IOException for me when executed using -Xmx1280m. If I use -Xmx768m, I can increase the buffer size up to around 300MB, but never to a size that I would think I could map.
    try
    String mapFile = "C:/temp/" + UUID.randomUUID().toString() + ".tmp";
    FileChannel rwChan = new RandomAccessFile( mapFile, "rw").getChannel();
    ByteBuffer byteBuffer = rwChan.map( FileChannel.MapMode.READ_WRITE,
    0, 100000000 );
    rwChan.close();
    catch( Exception e )
    e.printStackTrace();
    I am hoping that someone can shed some light on the factors that affect the amount of data that may be memory mapped to/in a file at one time. I have investigated this for some time now and based on my understanding of how memory mapped files are supposed to work, I would think that I could map ByteBuffers to files larger than 500MB. I believe that address space plays a role, but I admittedly am no OS address space expert.
    Thanks in advance for any input.
    Regards- KJ

  • 4GB File Size Limit in Finder for Windows/Samba Shares?

    I am unable to copy a 4.75GB video file from my Mac Pro to a network drive with XFS file system using the Finder. Files under 4GB can be dragged and dropped without problems. The drag and drop method produces an "unexepcted error" (code 0) message.
    I went into Terminal and used the cp command to successfully copy the 4.75GB file to the NAS drive, so obviously there's a 4GB file size limit that Finder is opposing?
    I was also able to use Quicktime and save a copy of the file to the network drive, so applications have no problem, either.
    XFS file system supports terabyte size files, so this shouldn't be a problem on the receiving end, and it's not, as the terminal copy worked.
    Why would they do that? Is there a setting I can use to override this? Google searching found some flags to use with the mount command in Linux terminal to work around this, but I'd rather just be able to use the GUI in OS X (10.5.1) - I mean, that's why we like Macs, right?

    I have frequently worked with 8 to 10 gigabyte capture files in both OS9 and OS X so any limit does not seem to be in QT or in the Player. 2 GIg limits would perhaps be something left over from pre-OS 9 versions of your software, as there was a general 2 gig limit in those earlier versions of the operating system. I have also seen people refer to 2 gig limits in QT for Windows but never in OS 9 or later MacOS.

  • File size limitation to import into imove

    I can't import a movie into imove that is 999 mb. Does this application have a file size limitation. The file is saved as a *.m4v. Thanks for your help using imovie 09.

    EyeTV should have an iMovie 09 Preset. That should make sure there are no extra tracks included.
    Another way to get files out of EyeTV3...
    Get MPEG Streamclip, which is free.
    IN EyeTV 3, right click on the recording, and Reveal in Finder
    Right click on the .eyeTV file in the finder and SHOW PACKAGE CONTENTS
    Drag the .mpg file into MPEG Streamclip.
    FILE/EXPORT TO QUICKTIME from MPEG Streamclip, choosing Apple Intermediate Codec.
    Import this AIC file, which will be in a .mov container, into iMovie.
    Note: You may need the Apple QuickTime MPEG2 Playback Component for this to work. MPEG Streamclip will tell you if you do. It costs $20 from Apple.

  • Android file size limitation?

    How can I package an Android app that is over the 50mb limit using Flash Pro CS6 and Air?  Google now allows for additional content to be downloaded separately ...

    OK ... so I called tech support on the phone and spent 15 minutes trying to convince them then Flash Pro CS6 could be used to create an Android app..  The conversation went nowhere.  Uhhhhgggg!!!
    Here's the deal ...  Flash Pro CS6 is advertised as being able to create Android apps.  The 50MB file size limitation may not be a big deal for many people right now, but give it a year or two.  Most phones coming out have HD screens.  How can you pack all the assets of large game into <50MB???
    So ... I'm going to continue to bump this thread (and the two other ones I have going) until I get a knowedgable response from Adobe. 

  • Premiere Pro CC 2014 file size limits?

    Hi a friend needs to create a 37hr uncompressed AVI file (by combining an avi of pictures and mp3 of audio of a performance) and is wondering if it can be done using Adobe Premiere Pro CC 2014, ie are there any file size limits? Any comments much appreciated.

    Would be interesting to know how you are going to store that. 37 hours of HD uncompressed in an AVI wrapper requires around 24 TB of free disk space on a single volume. That means you would need  something like 12 x 3 TB drives in Raid6 + 1 HS, requiring at least a 16 port raid controller for those 13 disks, just for the output file. Due to fill rate degradation, that is cutting it thin. Additionally at least a X79 or X99 motherboard with 2011 socket is necessary.
    Next question is, who would be crazy enough to marathon-watch 37 hours of a performance?
    You may consider another workflow, not uncompressed and not 37 hours.

  • Web.Show_Document - Is there a file size limitation?

    It appears that Web.Show_Document has a problem displaying large .pdfs.
    Example: A .pdf size of *2505 KB* would not display, however I compressed the .pdf to *1172 KB* and the report displayed using web.show_document successfully.
    I am displaying the .pdf in an Oracle forms using web.show_document. The user presses a button (View Report) and it displays the report. Except, now it is not displaying reports close to 2000 KB in size.
    The error says **"Exhausted Resultset"**
    Is there a file size limitation with web.show_document?
    Environment Background:
    Forms [32 Bit] Version 9.0.4.1.0 (Production)
    Oracle Toolkit Version 9.0.4.1.0 (Production)
    PL/SQL Version 9.0.1.5.1 (Production)
    Report Builder 9.0.4.1.0
    ORACLE Server Release 9.0.1.5.1
    Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production

    As already mentioned, WEB.SHOW_DOCUMENT has nothing to do with file size. This command simply sends a url to the system's default browser. There is no Oracle magic here.
    To the problem, you said:...The error says **"Exhausted Resultset"**Where are you seeing this message?
    Is Forms generating this message?
    Is this a custom message?
    Is this the complete message text?
    Is there an error number?
    This does not appear to be a Forms generated error message.
    I would suggest your store a large file in the same location as where your reports are located. The file should be of the same format (i.e. pdf). Open a browser and manually enter the necessary url to retrieve the content. I suspect the same problem would reproduce IF you believe the problem only occurs when the form calls WEB.SHOW. If it does reproduce then you have at least simplified the problem to a client browser requesting a document from a server.

  • ICloud File Size Limitation

    I recently updated my iCloud storage to 1 TB in anticipation of making better use of it once the new Yosemite OS was released.
    My first impressions of iCloud drive are not good.
    The free space on the drive is the same as the free space on my local computer hard drive.  It is working like Dropbox but there is no way to do a selective sync.
    I wanted to back up my iPhoto library from external drive to the Cloud and it said I didn't have enough room. My file is 166 Gig so in order to back it up I would need equivalent free space on my local drive.  Not Good.
    Then when I disabled icloud Drive on my Mac and tried to upload to the drive through the web I ran into the 15 gig max file size limit.
    So, after spending all this money for extra 1 TB storage it looks like I can't even use it to back up my iPhoto library or my iTunes library.
    Not impressed :-(.
    I hope that Apple has plans to remove the file size limitation very soon.
    If I have a 1TB cloud account I would like to use it like any other external hard drive without limitations on file size and I am hoping that Apple won't throttle the maximum number of files uploaded per day or per hour as other cloud services do.
    When I updated my storage to 1 TB a few months ago there was no indication that these limitations existed.  If they did I wouldn't have upgraded.

    So my frustration is that I am paying $20 a month for the larger storage and can't use it to back up my files.
    That storage is entirely separate than the iCloud Drive.  The following is from this Apple document: iCloud: iCloud storage and backup overview
    Here’s what iCloud backs up:
    Purchase history for music, movies, TV shows, apps, and booksYour iCloud backup includes information about the content you have purchased, but not the purchased content itself. When you restore from an iCloud backup, your purchased content is automatically downloaded from the iTunes Store, App Store, or iBooks Store. Some types of content aren’t downloaded automatically in all countries, and previous purchases may be unavailable if they have been refunded or are no longer available in the store. For more information, see the Apple Support article iTunes in the Cloud availability by country. Some types of content aren’t available in all countries. For more information, see the Apple Support article Which types of items can I buy in my country?.
    Photos and videos in your Camera Roll
    Device settings
    App data
    Home screen and app organization
    iMessage, text (SMS), and MMS messages
    Ringtones
    Visual Voicemail
    This was in place long before the iCloud Drive was introduced. 

  • AEBS File Size Limitation?

    I have a fat32 disk connected to a powered hub which is connected to my AEBS. I cannot copy or access files larger than 2gb. Any mp4 movie file over 2gb will not copy to/from Macbook or play in iTunes, Frontrow, or Quicktime.
    If I connect the disk directly to the Macbook the files copy and play in Frontrow and Quicktime without a problem.
    Is there a file size limitation on AEBS?

    OK. Here is what I got.
    After I roll back my AEBS firmware back to 7.0, I don't see any problem copying file larger than 1GB or 2GB or whatever even if with FAT32 any more.
    It is true that FAT32 limit file at 2GB but I guess it is not the main problem here. To me, it seems to be firmware 7.1 problem. Some may not see this problem but most of people see it.
    Here is how to roll back the firmware
    1. Make sure to unplug/disable all connection to Clients & WAN to be safe while firmware upgrading.
    2. Use MAC to roll back by hold "option" while click "Check for updates" then select firmware 7.0.
    3. After it is done downloading, select base station and click "Base station" menu -> upload firmware
    4. Choose 7.0 and wait until it done.
    Congrat!! you got 7.0 roll back. Dont' forget to disable automatic update.

  • Report file size limitation when printing?

    Does anyone know of a file size limitation when printing a .NET run Crystal report? We run a browser app, which opens a new browser when a report is printed. That works fine. When we PRINT, the ActiveX print dialog box appears. If the report is large (> 40 pages or so) it crashes our entire application. It works ok if we export to PDF then print, but I am trying to get to the bottom of why it is crashing.

    Hello,
    What version of Cr and .NET?
    Does your printer have limited memory?
    Is it local printer?
    Have you tried installing the latest Drivers for it?
    What Browser are you using and have you tried any other?
    40 pages not much local memory so it shouldn't be a problem.
    Create a new Printer and select File rather than port or LPT as the destination to see if it's a physical printer or network issue.
    Try a different printer altogether also.
    Also refer to Rule of Engagement posting before submitting your question so you provide as much info first.
    Thank you

  • 3220 Ringtone File Size Limitation

    Is there a file size limitation for this phone? My phone responds with file corrupt if i try to load anything above about 20k. All seem ok if under this size - all get reported as corrupt if above?
    Has anyone managed to use a ringtone with this phone using a file size of above 25k?

    Are you using the Nokia software to load the ringtones onto the phone? You cannot just copy midi files (".mid"), they have to be converted into a special format. Some midi files are copyright-protected and will not work, but I have added customised ring tones to my own, and my daughter's Nokia 3220's successfully. Next on the list is another 3220 for the other daughter, complete with her choice of ringtones !

  • PDF file size limited to graphics memory in Reader?

    I've created a form (in LiveCycleDS) that allows for an unlimited number of photos to be loaded into it. I put an image into a subform that is duplicated every time a user clicks a button thus creating an unlimited number of images that can hold photos. I then extended it with Reader Extensions.
    I'm running into a problem when I try to load a large number of photos into the form.  It gets to about 47MB of images when it locks-up Adobe reader.  I've been able to bring up other applications after the lock-up and when I switch back to Reader the artifacts of the other application are then displayed within Reader.
    What is the practical limit to the size of a file created with LiveCycle?  Is it tied to the amount of graphics memory a computer has?  My machine has 2GB of RAM while my video card has only 384MB.  I haven't been able to figure out if there is a file size limitation.

    It's entirely normal for file size to increase. PDFs are much more compressed than print streams. For some printers the print size is almost constant (a huge bitmap), for others, it's a collection of graphical items and the size varies enormously. Rarely anything you can do.

  • Upload File size limitation in AIR ???

    Is there any upload file size limitation in air application ? Can any one post me the related articles on AIR application Multiple file upload ??
    Regards,
    Rahul.

    Hi Rahul, i dont understand completly your question, but i was have a similar situation some years ago.
    The limitation is not by AIR, all local servers(wampp, xampp, etc) are limited in the command UPLOAD_FILES.
    This have by default 3 or 5 mb by each file to can be uploaded, only you have to do is change the default value in php.ini file to this line
    "upload_max_filesize".
    I hope this will help you
