Documentation of the detailed process of transactions?

Hello

I work currently on a project based on "Oracle . NoSQL" as head hierarchical storage I'm just curious, how ONDB handles their transactions." I have scoured the attached documentation unsuccessfully. The only thing I could find were all titles or phrases of marketing (as 'Flexible ACID transactions, a Berkley DB')

NoSQL Oracle database transactions

NoSQL of Oracle database (Version: 12cR1.2.1.57 Enterprise Edition, 2014-01-10 06:21:46 UTC)

Oracle Berkeley DB Java Edition | Oracle Berkeley DB

http://Indico.CERN.ch/GetFile.py/access?resId=0 & materialId = slides & heats = 159716

In the documentation of Berkley DB J’ai found a section arguing that BDB handles their transactions through JTA. From ONDB is based on Berkley DB Idid assume that transactions will be processed the same way. Please correct me if I'm wrong.
However, it is not the result I'd do it love to hear. are there any detailed documentation for the transaction treatment?


If anyone of you have an idea or a tip where I could find such a thing?


greeting

Sascha

I think that the best thing that can be for you to read the source code (available in CE version).

In src/oracle/kv/impl/api/RequestHandlerImpl.java's executeInternal, you will see him call beginTransaction and commit().

Then, in src/oracle/kv/impl/api/ops/Execute.java's execute() you'll see how it sorts by key operators and then executes each of them.

IHTH.

  • When Mozilla online banking does not permit me to see the details of a transaction so that Internet Explorer will allow it. Mozilla has been done, but not now.

    I do my banking online with Bank of America, usually using Mozilla Firefox. Recently I noticed when I clicked on a banking transaction to see the "details" or print only this particular operation, it only allows me to see the details.

    Previously, whenever I clicked on a transaction, to see the image of a control I wrote for example, he always brought to the top of an image of the cheque. Now, he won't do it.

    If I use Internet Explorer, I can click on a specific bank transaction and see the details, exactly how I used to be able to do this with Mozilla Firefox.

    Therefore, the problem is with Mozilla and not the website of Bank of America, right?

  • Documentation of the painting process: stamp Visible, move to layer together and hide

    I love to capture my screen painting and when I'm actually I make a GIF animated these shots '' process. '' I am trying to automate the process and I managed to find that meets my needs:

    #target photoshop

    app.bringToFront ();

    Stamp the visible layers

    var idMrgV = charIDToTypeID ("MrgV");

    var desc2 = new ActionDescriptor();

    var idDplc = charIDToTypeID ("Dplc");

    desc2.putBoolean (idDplc, true);

    executeAction (idMrgV, desc2, DialogModes.NO);

    Move the active layer for the background of LayerSet 'process '.

    var activeLayer = activeDocument.activeLayer;

    processFolder var = activeDocument.layerSets.getByName ("process")

    activeDocument.activeLayer.moveToEnd (processFolder);

    Now I would like to add a condition to check, whether or not the 'process' layer-set exists, and if not, create it. It should look like this:

    Process Image capture

    V 0.3

    Stamps PEAK Visible (creates a new layer that combines all information visible in the flattened form) and who moves to a 'process' Layer Set.

    Layer is then hidden.

    If the defined layer is not there, it will be created.

    #target photoshop

    app.bringToFront ();

    Check the 'process' layer-Set on the root. Create, where it is not present.

    If (! activeDocument.layerSets.getByName ('process')) {}

    activeDocument.LayerSets.add ();

    activeDocument.LayerSets.name = "process";

    }

    //

    / * {else}

    }*/

    Stamp the visible layers

    var idMrgV = charIDToTypeID ("MrgV");

    var desc2 = new ActionDescriptor();

    var idDplc = charIDToTypeID ("Dplc");

    desc2.putBoolean (idDplc, true);

    executeAction (idMrgV, desc2, DialogModes.NO);

    Move the active layer for the background of LayerSet 'process '.

    var activeLayer = activeDocument.activeLayer;

    processFolder var = activeDocument.layerSets.getByName ("process")

    activeDocument.activeLayer.moveToEnd (processFolder);

    activeDocument.activeLayer.visibility = false;

    The condition seems to be causing the problem, but I have no idea how to solve this problem. If anyone can help?

    OK, here's the script that performs the Act, it requires an additional function to catch what getByName() returns.

    Process Image capture

    V 1.0

    Stamps PEAK Visible (creates a new layer that combines all information visible in the flattened form) and who moves to a 'process' Layer Set.

    Layer is then hidden.

    If the defined layer is not there, it will be created.

    #target photoshop

    app.bringToFront ();

    Check the 'process' layer-Set on the root. Create, where it is not present.

    If (! hasRootLayer ('process')) {}

    var addedLayer = activeDocument.layerSets.add ();

    addedLayer.name = "process";

    }

    Stamp the visible layers

    var idMrgV = charIDToTypeID ("MrgV");

    var desc2 = new ActionDescriptor();

    var idDplc = charIDToTypeID ("Dplc");

    desc2.putBoolean (idDplc, true);

    executeAction (idMrgV, desc2, DialogModes.NO);

    Move the active layer for the background of LayerSet 'process '.

    var activeLayer = activeDocument.activeLayer;

    processFolder var = activeDocument.layerSets.getByName ("process")

    activeDocument.activeLayer.moveToEnd (processFolder);

    activeDocument.activeLayer.visibility = false;

    Function to check if the 'process' layer exists, passes result returned as a Boolean value

    function hasRootLayer (layerName) {}

    var hasProcessLayer = false;

    try {}

    hasProcessLayer = (typeof activeDocument.layerSets.getByName (layerName)! = "undefined");

    } catch (e) {}

    Return hasProcessLayer;

    Hi there is community,

    just guessed myself. The solution is mentioned in the documentation - look @ https://docs.oracle.com/middleware/1213/soasuite/develop-soa/bpel-transaction-semantics.htm#SOASE85811 table 13-2 BPELCaller called BPELCallee that has bpel.config.transaction set to requiresNew.

    What I did:

    1A added another BPEL to call my the original (as mediator)

    2. my original BPEL has been configured with bpel.config.transaction = requiresNew. What original BPEL processes is to start its own global transaction, other than the one initiated by my caller process that has been suspended.

    3. in my original BPEL in the case of exceptions or abnormal situations I launch/recovery flaws of the company. According to the documentation, this cancels the new transaction (from my original BPEL). The exception is caught by the calling process and appropriate response is generated on my composite consumer. The data is correctly saved (not) in the DB.

    See you soon,.

  • STOP: c0000221 {Bad Image Checksum}. The image rpcrt.dll is possibly corrupt and recovery XP says error during the extraction process. Details of error: path not found___

    My friend turned on their laptop packard Bell recently and had the following problem. Windows XP screen loads but is then followed by a blue screen that says STOP: c0000221 {Bad Image Checksum}. The image rpcrt.dll is possibly corrupt. The header checksum does not match the checksum calculated.

    I can't the laptop to go further. I have accessed the Microsoft recovery Panel and try a non-destructive recovery as there are some precious photos that need backup. However, when you select 'no profile' to begin the recovery, I get the message:

    Error during the extraction process. Details of error: path not found

    I'm a bit of a novice when it comes to this sort of thing, but if someone can provide step by step help giving rise to lose photos, I'd be willing to give it a try. I also have XP Home Edition disk that came with the laptop but has never been opened. Any help would be appreciated. Thank you

    You hear your message said something about rpcrt4.dll?  It is important to relay the exact message you see.

    Please provide additional information on your system:

    What is your system brand and model?

    What is your Version of XP and the Service Pack?

    Describe your current antivirus and software anti malware situation: McAfee, Norton, Spybot, AVG, Avira!, Defender, ZoneAlarm, PC Tools, MSE, Comodo, etc..

    The question was preceded by a loss of power, aborted reboot or abnormal termination?  (this includes the plug pulling, buttons power, remove the battery, etc.)

    The afflicted system has a CD/DVD drive work?

    You have a true bootable XP installation CD (it is not the same as any recovery CD provided with your system)?

    You use some CD to access this Panel of Microsoft recovery where this "no profile" option is?  I don't know what all this means if it isn't some CD shipped with your system, in which case, I would use it for a coaster instead of something to fix your system.

    If the c:\windows\system32\rpcrt4.dll file is missing or afflicted, you do not start in the last good known Configuration.

    You also will not start in any kind of Mode safe no more.

    Even if you could boot mode safe, you would find that sfc/scannow does not work in Mode without failure in all cases (never).  If you try it, you'll see a message like this:

    Windows file protection could not initiate a scan of protected system files.

    The specific error code is 0x000006ba [the RPC server is unavailable.].

    Failed to start the RPC mode server safe either.

    I can't recreate your error exactly, but it is easy to replace the rpcrt4.dll file.  Looks like you have a working CD drive, so put yourself a Hiren boot CD and when you started on this, you can copy your precious files to a USB device for safety.

    There should be a backup copy of rpcrt4.dll already on your system, here or here:

    c:\Windows\System32\dllcache

    c:\windows\ServicePackFiles\i386

    You need to rename or replace the rpcrt4.dll file which is in c:\windows\system32 and replace it with one you will find the backup copies.

    There should be a backup copy of rpcrt4.dll already on your system, here or here:

    c:\Windows\System32\dllcache

    c:\windows\ServicePackFiles\i386

    When you get the Hiren's CD's, you can use to replace the missing or suspicious file.  If you need help with that, first get the Hiren's boot CD made and start over, then we can continue.

    Do you have a Hiren BootCD you can download here:

    http://www.hirensbootcd.NET/

    On the left, click on download, scroll down, choose the latest version, the download link is a little hard to see.  It is at the bottom of the page, above the drop for older versions and looks like this (click this component to download the ZIP file):

    Direct HTTP mirror + Torrent, Torrent Magnet

    Click the "Live HTTP Mirror" link to start the download and save the ZIP file on your desktop of somewhere that you can remember.

    The ZIP file is large, so the download will take probably some time to complete.  Then unzip the download to extract the Hirens.BootCD.ISO file that will be used to create your new bootable CD.

    Create a bootable CD. ISO file is not the same as simply copying the. File ISO onto a blank CD.  You must use software that includes how to burn a. ISO to a CD to create a bootable CD.

    File ZIP the Hiren is the file BurnToCD.cmd that you can double-click to launch it.  The BurnToCD.cmd will use the file BurnCDCC.exe to burn the. ISO file onto a blank CD using your existing CD burner.  You can also use your own burning software as long as your software is able to create a bootable CD. ISO file.  More modern burning programs can create a bootable CD. ISO image.  Create a CD from an ISO image bootable is not the same as just the file on a CD burning.

    If you need a simple and CD burning, this is a free software popular software:

    http://www.ImgBurn.com/

    Here are some instructions for ImgBurn:

    http://Forum.ImgBurn.com/index.php?showtopic=61

    It would be a good idea to test your new bootable CD on a computer running.

    You may need to adjust the computer BIOS settings to use the CD-ROM drive as the first device to boot instead of the hard drive.

    These adjustments are made before Windows tries to load.  If you miss it, you will need to restart the system again.

    When starting on the Hiren's CD, you will see a menu of options.  Choose Mini XP.  It will appear while Windows is loading and you will be presented with a desktop computer that has the look and feel of the interface of Windows Explorer, you are already accustomed to using.

    Using the Mini XP, you can access Internet, maneuvering around your system, search for files, copy files, replace the files and run the scans for malware, edit the text files (like the c:\boot.ini) etc.

    There are dozens of free and useful tools included in the CD that can be used to repair your system or copy your important personal files on another device (like a USB device or an external drive) in the case where you just give up and decide to reinstall your XP (I hope that you will not make this decision)

    Do, or do not. There is no test.

    I need YOUR voice and the points for helpful answers and propose responses. I'm saving for a pony!

    KasunA

    Found a workaround.  The problem is that, before the 7695070 patch is applied, the installation program backup directory/apps/fs2/FMW_Home/webtier/jdk in /apps/fs2/FMW_Home/webtier/jdk_backup_existing_version, but then it clears. / jdk - the patch fails because it can't find it.  I had to rename the directory of the jdk for jdk2, and as soon as it gets deleted quickly and rename jdk2 jdk.  Then he applies the patches without problem.  A symbolic link would do the same thing.

  • In the bpel process one-way transaction management

    Hello

    I created a one-way bpel process with oneWayDeliveryPolicy property - property Sync and transaction - required. When I exposed this service as a SOAP service, I see well The Participation of Transaction in the Web Service adapter in the way of exposed Services configured as EVER. Is this to say that BPELCallee would not participate in the same transaction as the appellant BPEL?

    Aditya

    Hello

    Properties refer to the support of different transactions "contexts", as you can see in the documents below. The bpel.config.transaction refers to the semantics of Transaction BPEL Process Manager, while the 'Participation of the operation' refers to WS-AT , which provides interoperability of transaction between Oracle WebLogic Server and transaction of other providers services... I've never tested it myself, but I guess that if you process BPEL transactions, the bpel.config.transaction will prevail...

  • Documentation of the API for CWIMAQControls

    I am a software developer with several years of experience in medicine and other sciences, but now is working on a software project using National Instruments IMAQ customer in .NET and have no prior experience with image processing.  The only I can find the API documentation is a help file with the product intalled.  Then this under did a good job explaining the service inputs and outputs, it is light on the explanation in a real retail functions actually do.  Under .NET (not my favorite but this is what I got), I can get a good summary of the objects and their properties / methods, which is useful.  I see there are a lot of good material in this forum, but what I need right now is good basic documentation.  I also noted a plethora of PDF files in the directory of installation but found nothing there or on ni.com which gives me the level detail fo I need.  When I think that the documentation of the API, I expect something as complete what Sun Microsystems offers with any JDK Java - it seems that the doc API IMAQ assumes a certain level of ease and does not for someone like me come with literally no background outside a lot of math (algebra of vector fortunately!) and science in College courses.

    Am I missing something?  I see that there are many examples of programs and I can get what want from those, I guess, but I do not charge my client for all the time it will take, if there is a more ready fo source information.

    Now, I realize that the field of the treatment of the image is large and it would be difficult to develop a software of this nature without a learning curve.  So I have

    I studied through two web queries image processing and having bought the book 'Digital Image Processing (Gonzalez, wood).

    Specifically, I was put to zero in on what is needed for the task at hand: "blob detection" and "blob tracking movement."  It seems pretty clear to me, some have become familiar with the image processing basic terminology and methodologies that have been developed for tracking, and image recognition of movement IMAQ software can do what it takes.  At this point, I can do basic things with objects presented in .NET.  It is analogous to maybe ask a kid who just the definition of an equilateral triangle to solve differential equations.

    In this case, what I really need is one or more examples of programs that perform functions similar to what I want to do.  Is there any suggestions in this regard?  My research on ni.com revealed evidence of the items of "blob detection" and "blob motion" and I see that these were used for tasks as complex as the particles of follow-up and the counting of blood components.  I don't see and od you expect not to see any object, follow also specific methods than what I need to do - which is in fact quite abstract - and chart the path of the blob more to light to the camera image gained when it moves in real time.

    It's a strange feeling to have been programming for decades, and then enter a field where the customer needs require me to act as a nini who has not done its homework.  But it's the nature of the job.  The pointers will be appreciated.  If I missed something obvious I don't even mind being reprimanded to be unobservant or lazy.

    Thank you very much in advance for any assistance that may be provided.

    tsfarrell-

    Have you looked at the manual of the Vision Concept?  (it should be in the form of PDF in the documentation directory, or you can see it here) It has a more detailed description on what our algorithms.

    We also ship many examples for .NET - those of the 2. Functions\Binary analysis file dealing with blob detection and may be useful.

    Good luck to you on your application!

  • Is there a documentation about the configuration of the function keys (program)

    Is there a documentation about the configuration of the function keys (program).

    Dell Dimension 1400, model XP SK8110 keyboard.   Yes, I know there are 7 years old, but running like a champ.

    Hello

    You can use various function keys to activate certain features and commands only. The following list details the current functions keys, what they do, and when you can use them.

    Three keys can be used when Setup is loading and when you are prompted to press the F6 function key to install some third-party small computer system interface () SCSI and host controller drivers:

    • F5 - for computer type or hardware abstraction layer (HAL) selection
    • F6 - to install the SCSI controller drivers and third-party host
    • F7 - to run Setup without Advanced Configuration and Power Interface (ACPI)

    When the "Welcome" screen is displayed, the following function keys can be used:

    • F2 - to automatically start the process (ASR, Automated System Recovery).
    • F10 - to bypass the menu screens and to load the Recovery Console

    During the GUI (GUI) - Mode Setup, the following function keys can be used:

    • SHIFT + F10 - to enable access to a prompt during the installation in graphical Mode
    • SHIFT + F11 - to display "old" wizards that give more detail.

    Thus, it is not possible to configure the function keys to perform this task. However, you can use your favorite search engine to perform this task.

    Warning: Using third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

  • Failed to initialize for the logon process

    My phone displays the following message when I turn it on (the screen is black, but this message shows): failed to initialize for the logon process
    The interactive logon process initialization has failed.
    For more details, please see the event log.

    Clicking OK doesn't do nothing, the message just keeps reappearing.  I tried stopping and starting Windows up in Mode without failure.  The message appears in Safe Mode, as well.

    Hello berniesun,

    You can give the Startup Repair to try to clear this error. I've included the steps located in the help section on all versions of Windows Vista. If you want to print these instructions for yourself, you can go to help & Support in the Start Menu and type the Startup Repair in the top search box.

    Check back with us and let us know if this solves your problem.

    If you have a Windows Vista installation disc, you need to restart (boot) your computer using the installation disc. If you do not restart your computer from the disk, the option to repair your computer will not appear.

    If you have a Windows Vista installation disc:

    1. Insert the installation disc.

    2. Restart your computer.

      Click the button start , click the arrow next to the button lock , then click on restart.

    3. If you are prompted, press any key to start Windows from the installation disc.

      Note

      • If your computer is not configured to start from a CD or a DVD, see the documentation provided with your computer. You may need to change your computer's BIOS settings. For more information, see BIOS: frequently asked questions.

    4. Choose your language settings, and then click Next.

    5. Click on repair your computer.

    6. Select the operating system you want to repair, and then click Next.

    7. In the System Recovery Options menu, click Startup Repair. Startup Repair can invite you to make choices as it tries to solve the problem, and if necessary, it may restart your computer, because it makes the repairs.

    If the Startup Repair tool is an option of recovering preinstalled on your computer:

    1. Remove all floppy disks, CDs and DVDs from your computer and restart your computer.

      Click the button start , click the arrow next to the button lock , then click on restart.

    2. Do one of the following:

      • If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then stop and restart your computer.

      • If your computer has more than one operating system, use the arrow keys to select the operating system you want to repair, and then press and hold F8.

    3. In the Advanced Boot Options screen, use the arrow keys to highlight repair your computer and press ENTER. (If repair your computer is not listed as an option, then your computer does not include startup as a preinstalled recovery option repair).

  • Select a keyboard layout, and then click Next.

  • Select a user name and password, and then click OK.

  • In the System Recovery Options menu, click Startup Repair. Startup Repair can invite you to make choices as it tries to solve the problem and, if necessary, it may restart your computer, because it makes the repairs.
