Does anybody know how Oracle load large N-Triple file into Oracle 11g R1?

Does anybody know how Oracle load large N-Triple(NT) file into Oracle 11g R1 by using sql*loader according to their benchmark results?
Their benchmark results indicate they have over come the large data set problem.
http://www.oracle.com/technology/tech/semantic_technologies/htdocs/performance.html
It means they have loaded LUBM 8000(1.068 Billion+ Triples) into Oracle successfully, but there is no detailed steps provided. For instance, 32-bit or 64-bit platform they used, only one NT file being used corresponding to one dataset or several NT files?
Is there any exception occured during the loading process if the NT file beyond 60GB? When using jena to generate NT file against LUBM(8000), the size of the NT file would definitely beyond 60GB.
We are dividing such large NT file into several small ones? Is it a good approach? I'm hesitating to do so!

A Linux 32-bit platform was used for bulk-load of LUBM-8000 1.106 billion (before duplicate elimination) RDF triples into Oracle.
Multiple gzipped N-Triple files were used to hold the LUBM-8000 data. zcat was used on all these files together to send the complete data into a named pipe. SQL*Loader used this named pipe as the input data file to load the data into a staging table in Oracle. Once the staging table was loaded, the sem_apis.bulk_load_from_staging_table API was used to load the data into Oracle Semantic Store.

  • Does anybody know how to solve this font problem?

    Hello everyone,
    I have had this font problem for weeks now and I can't seem to get it solved. There are a number of fonts that won't load properly in Illustrator, PS, and InDesign. They are loaded in the system, but refuse to show up in the list. I've installed them in the home directory/library/fonts. These are commercial opentype fonts and one homemade opentype font. Sometimes the font that I created will appear, other times it does not, but many other fonts refuse to show up in the font display lists of these 3 software packages.
    I've cleared the font caches with FontNuke, everything looks like it should work properly, but it does not. Also, with Font Book, I've resolved any duplicate font problems. Does anybody know how to solve this problem? Is this a known CS4 bug?
    Any help would be greatly appreciated. I'm using the latest Mac Mini and CS4 software.
    Thanks in advance.

    Hi,
    How do I check if the fonts have the correct creator and so on?
    Anyway, I've spent the better part of today validating and removing suspect
    fonts. Why does the right click choice for resolve duplicates and the
    validate font behave completely differently in Font Book? I discovered that
    when this is investigated further with the validate font command, I found I
    had a massive amount of duplicates that according to font book cause minor
    errors. I thought that would have been sorted out with the resolve duplicate
    command, instead I ended up check marking and manually removing the fonts
    that had minor errors.
    I still have many commercial fonts plus my own font not showing up in
    Illustrator or PhotoShop. If I copy and paste the font directly into
    InDesign's font folder, my font shows up. I also tried removing my font to
    see if this would fix any of the other problems. It doesn't. I did type in
    my font name in the console dialog box and this message is displayed for
    this font as well as mine and many others.
    10-04-06 5:21:09 PM Font Book[12940] ##### ERROR:  The font system thinks
    the font
    file://localhost/Library/Fonts/Voluta%20Script%20Pro/VolutaScriptPro-Regular.otf
    is active, but the file no longer exists!
    Then I went back to font book to check to see if it is there and it is
    enabled. For my font the caution triangle appears with the multiple copies
    of the font is installed. Resolving duplicates doesn't solve this problem.
    Any ideas of how to fix this problem?
    Thanks

  • Installed Yosemite and now lost apps and also my App Store does not open. Does anybody know how to fix the problem?

    Some weeks ago, I installed OS X Yosemite, as shown on my App Store, that was a "System Update available for my IMac 2009". Followed all the steps, normally and installed it as I did many other times ago (with the Maverick, Mountain Lion, OS X).
    Just after the installation, I noticed that every single folder or program that depends on "Apple", stopped working.
    Examples: Office package opens normally, so as Firefox. But, IPhoto, ITunes, Safari and App Store itself do not.
    That is causing me fear, because even trying to reinstall Yosemite or return to the one I had before, using App Store became impossible. Even the "Apple Icon" on the top left corner does not work. I click, it flashes, just IF it was ready to open, but nothing happens, seams that have something stopping the "loading process" of the softwares.
    Does anybody know how to fix the problem, please?
    Thanks in advance. Regards.

    Thanks for your attention.
    I Tried before, but the Mac App Store was not responding either, and worse, after 5 years, There is no free phone support
    I ended up solving it by reinstaling the Yosemite pressing "comand + R"
    thanks anyway
    Regards

    How Restore Deleted or Missing OS X Components
    A few of the basic OS X installed applications can be restored from the Optional Installs installer located in the Optional installs folder on your Installer DVD.  However, if what you need is not there then follow the instructions below.
    How to Use Pacifist to Restore Deleted or Missing OS X Components
    Insert the OS X Installer DVD into the optical drive.  Use a simple utility like TinkerTool to toggle invisibility so you can see invisible items.  Alternatively, open the Terminal application in your Utilities folder and at the prompt enter the following:
    defaults write com.apple.finder AppleShowAllFiles Yes
    Press RETURN.
    To turn off the display of invisible files repeat the above command substituting No for Yes.
    The install packages are located in the /System/Installation/ folder on the DVD.
    Download the shareware utility Pacifist. Use it to extract a fresh copy of the missing item(s) from the file archives on your OS X installation DVD. The file archives are in the /System/Installations/ folder (use Go to Folder option in the Go menu of the Finder.)
    Here are Four Basic ways to use Pacifist (courtesy of George Orville.)
      A. Drag a .pkg icon onto the Pacifist window .....proceed to step 7.
      B. Click on “Open Package ....” and navigate to package desired and click “Open” in
           the open/save window.....proceed to step 7.
      C. Insert Mac OS X installer CD and when it mounts, navigate to .... Menu->Go->Go
           to Folder. In the path field enter or paste ....
    /Volumes/disc name/System/Installation/Packages (where disc name is the name of the CD/DVD that you inserted.)
    Click on the  "Go" button ..... • Drag a .pkg to Pacifist..... proceed to step 7.
    The package you'll need will have to be discovered by trial and error, but for most applications you should start with the Essentials.pkg and/or Additional Essentials.pkg.
    D. Insert your Mac OS X install disk 1 .... and open Pacifist.
    1. In Pacifist, select "Open Mac OS X Install Packages" ... dialog may appear asking for disk 2, then disk 3 and finally disk 1 again.... {if DVD is not used)...If “Stop Loading” is selected...the procedure will stop!!!
    2a. When loading is complete, a new window appears, click the triangle to display contents of each package...Select item and proceed to step 7.
    2b. or click the “Find” icon in the Pacifist window and type the name of the software you need.
    3. In the list that comes back, click the top most entry for the item that you want. ..... that is the one for the English language.
    4. On the top of the Pacifist window, click “verify” .... you will probably be prompted for your password.
    5. Enter checks for.... “verify permissions” and “verify file contents.” and click “verify” ....enter password when prompted.... you will get back output which may look like this:
      20 files were scanned. 20 of 20 files were present on the hard disk. 0 of 20 files had file permissions that did not match those specified in the package. 0 of 20 files had checksums that did not match those specified in the package.
    6. Click “close”. Go to step 7.
    Extract or Install........
    7. In the Toolbar (upper left), you now have the option to extract or install. Click a file in the lower list and those two icons will be enabled.
    8. If “Extract to...” is selected.... navigate to the location where the file will be placed, select “choose”, select “extract” in new dialog that appears,authenicate , if prompted, click “OK”.
    9. In the next dialog, click “Extract”.
    10. If “Install” is selected... dialog will appear with the location/path of the installed software. Click “Install”
    11. Type in your password, click “OK”
    Pacifist will begin to extract files.
    12. In steps 8/10ß.... you also have the choice to “cancel”
    Notes: Pacifist may find that a file it is installing already exists on the hard disk. Pacifist will present you with an alert panel....
      • Stop
      • Leave original alone
      • Update .....
      • Default selection
      • Replace .... (Replace option should only be used on full install packages)

  • Page numbers displayed incorrectly in TOC in new Pages - does anybody know how to fix this?

    I'm working on a multi-section document with a single TOC for two sections. Section one uses lowercase roman numerals (i, ii,...) and section two arabic numerals (1, 2, ...). The page numbers are displayed correctly on the pages themselves, but in the TOC the first two headings from section two (pages 1 und 3) are displayed as "i" and "iii". This only started after the update to pages 5, everything was fine before that. Does anybody know how to fix this? I already tried deleting the TOC and inserting a new one and changing the numbers to uppercase letters and back, to no avail.
    thanks for any input

    Go back to Pages '09 inside the iWork Folder inside Applications.
    There are so many problems with Pages 5 it is difficult to know where to begin.

  • I need to erase the contents of my phone and restore to factory settings. Does anybody know how to save your texts so you don't lose them?  Can I back those up to iCloud?  My phone was very likely hacked (Apple's advice was to call the police!)

    "I need to erase the contents of my phone and restore to factory settings. Does anybody know how to save your texts so you don't lose them?  Can I back those up to iCloud?  My phone was very likely hacked (Apple's advice was to call the police!)"
    That was all I could put in the initial "box."  Then it brought me to this page with instructions on how to write a good sentence.
    Proceeding ...
    After going back and forth between Apple, AT&T and the police (all telling me to go to the other two) I took AT&Ts suggestion and got a new number. One tech warned against doing a backup, especially on my Mac, saying if my phone had been hacked then whatever bug was there would then invade my computer. But nobody knows how to determine if the phone has been hacked or a virus was planted there. Unfortunately I know who would have reason to do such a thing and all I can say is that he is at the top technologically and could easily do it. Almost impossible to prove, however.
    So I need to preserve my text messages and my emails as well. I backed up my photos to that Microsoft product (One-Drive) and it froze (Surprise, Surprise) with four short videos to go, and no way of stopping that (when I tried it crashed repeatedly) so I'm in crisis mode here.
    Help ...

    Thanks!

    Betty I don't know if you fixed your hacking problem but I feel your pain. I've seen some strange things going on between my iMac and my iPhone and Apple has told me the same thing, call the police which I have done. The hackers have stole 500.00 out of my checking account have access to every internet account I use and no matter how often I change the password their right back on the account. I closed my FB account 3 times only to have someone reopen it. Right now I've got a link in my reading list (Safari) that if I click on it, it allows me to log onto my FB account anonymously.
    I've seen a green folder come out of no where while I was trying to delete my passwords out of keychain when that green folder was put into the key chain I was immediately locked out. I than went into system preferences to try to make changes to my security settings, when I clicked on the icon it wouldn't open. I've seen log files of automator receiving commands and sending out my personal information thats on my computer.
    I have a legitamate program called iExplorer that allows you to look at the contents of your iPhone back ups and saw a transaction someone made at the Apple store for some full length movies, some albums, ibooks and other apps but when I called the iTunes store and they said none of those items were showing up on my account. If their not on my account how can they be on my iPhone 6? One day someone was using my gmail account and unknowingly used google maps to search for an Italian restaurant, than a Mexican restaurant than a coffee shop and their search showed up on my iPhone but I didn't have my gmail account installed on my iPhone 6. Using my computer I logged onto my gmail account and looked at the maps history and sure enough there were the searches when I'd hover my curser over the link it gave me the longitude and latitude of the where the hacker was when he was using google maps. I know whoever reads this thinks Im crazy but I've documented everything and can prove the things that I have mentioned in this post actually happened.
    One day I had my laptop (pc) and my iMac next to each other as I was using both. when I clicked on airport it showed that my laptop and my iMac had made a connection and were actually communicating with each other. I know I didn't do it I don't know how. The iMac was logged into my iCloud account while my laptop wasn't. I have formatted my iPhone at least a dozen times, Apple and an Apple retailer have formatted my hard drive not to mention the numerous times I have formatted it but the hackers keep getting on my devices. Im formatting my lap top at this very second because during the course of the night I left the ethernet cable plugged into it and they locked me out of my c: drive, and configured the system so I can't download any updates from Microsoft, overtime I type in www.microsoft.com it changes to ww38.microsoft.com which takes me to a blank page. I right clicked on the page I was redirected to and read the java script and couldn't believe that someone had actually configured Internet Explorer to redirect me to a blank page when I tried to go to Microsoft. Apples answer to all this is there was nothing wrong with my iPhone or my iMac and if I thought there was a problem to call the police which I have done.
    Theres no doubt the hackers are reading this while I type it or will read it and I simply don't care anymore. I no longer email anyone, don't use my iCloud account and have taken precautions to protect my credit but if I ever find out who has invaded my privacy to this extreme the police are going to want to talk to me because Im going to hurt them like they've never been hurt before

  • I have 2 iPhones - one for personal use and one for work. They are currently connected with the same Apple ID. I would like to separate the two accounts. Does anybody know how to do this?

    I have 2 iPhones - one for personal use and one for work. They are currently connected with the same Apple ID. I would like to separate the two accounts. Does anybody know how to do this?

    Just create a new AppleID for your work.
    As Allan suggested, items purchased on one iTunes account cannot be moved to the other account.
    However, you can put items purchased on on account onto the other iPhone.

  • I just got my dads old iPhone 4. I restored it to factory settings and set it up with my apple id. The albums in my music are fine in iTunes but on my phone the albums are split and each song is its own album. Does anybody know how to fix this?

    My dad has recently gotten a new phone and I got his old one. With his permission I restored it to factory settings and set up the iPhone 4 as a new phone with my apple id. Everything has downloaded fine but I have had many problems with my music. First it was where my phone didnt recognise my apple id, but I  figured that out. Then it was where iTunes took one of my albums and split it so all the songs where their own albums. I fixed the album split on iTunes but its still like that on my iPhone. I have looked online everywhere and I still haven't found a solution! I'm getting super frustrated! Does anybody know how to fix this?

    No it's not stealing. They have an allowance that you can share with so many computers/devices. You'll have to authorize her computer to play/use anything bought on your acct. You can do this under the Store menu at top when iTunes is open on her computer.
    As far as getting it all on her computer....I think but I am not sure (because I don't use the feature) but I think if you turn on Home Sharing in iTunes it may copy the music to her computer. I don't know maybe it just streams it. If nothing else you can sign into your acct on her computer and download it all to her computer from the cloud. Not sure exactly how to go about that, I haven't had to do that yet. I wonder if once you authorize her computer and then set it up for automatic downloads (under Edit>Preferences>Store) if everything would download. Sorry I'm not much help on that.

  • Hey, does anybody know how can i have two different apple ids on my mac imessages, because i have two mobile phones with different ids and i would like to be able to send imessages from both accounts on my mac. Tnx

    Hey does anybody know how to set up 2 apple ID on mac imessages? Because i have 2 different iphones and i would like to send imessages fron both accounts on my mac...

    Associate your mobile numbers with your Apple ID, if you haven't already done so.
    Sign out of iMessage on the Mac:
    Messages ▹ Preferences ▹ Accounts ▹ Sign out
    and on the iPhone:
    Settings ▹ Messages ▹ Send & Receive ▹ Apple ID ▹ Sign out
    Then, on the phone, tap
    Use Your Apple ID for iMessage
    Sign back into iMessage on both devices and test. If there's no change, you may have to wait for a change in network conditions.

    This is the best I can do. This way you can use the 2011 MBA way to do things.
    Look for the post from @jacktourist. (on page 2 about half way down) This seems to be the easiest.
