Massive insertions

Hi all.

I have the requeriment to massive load of data from CSV file to the database table. ~ 8000-10000 lines.
To achieve this, I have a View "tuned" for the inserted rows object.

However, the process becomes 'wait times' phase commit transaction.

How can I insert rows in the database but ADF BC? I'll put a progress bar o loading process the message, then performance is not a problem at the moment.
Which is the best way to make massive insertions in British Colombia ADF?
Can I block users in the application to change the information in the table while the massive load is underway?

Thank you.

Kind regards.

I also had a similar type of requirement. To be honest it is that no distinction between ADF BC sets in the complete filling of your condition. However, you can use batch on the BC layer validation operation. This means just to validate the files in batch processing. Do not wait until that to read the file integer svs and also try not to commit to the time. Then try to validate the data in a set of 10-20 records at a time. It will increase the performance.

I don't know that always he'll give performance problem.

Although this isn't a good approach if you use this feature frequently. Of course, it give error thread stack or maybe sometime it will work and sometimes not and also I want to say that any business (ADF BC or EJB) component is not appropriate to save as many records at a time. I know immediately that your condition is to realize this feature via ADF BC.

In addition, I also had the same requirement, but in our case, the file can contains data of 100000 or more. First I used ADF BC but it was allot of time. Later, I used oracle sql loader. you don't believe, but it's true that he used to stored data of size 100000 with 20 to 60 seconds.

Finally, I want to suggest, if you have the option to use sql loader then use it. It is always good to use sql loader if you deal with huge data.

Thank you

  • Performance problem, creating lines on viewobject

    Hello

    When a user pushes a button in my Oracle ADF 11.1.1.3.0 GUI.
    it triggers a method in my grain of support.
    This method is called insertNewForecastTable, which takes a (tree) card called forecastMap as input. (see below)

    (The key of this map is a Timestamp,
    the value of this card is a ForecastEntry object.
    A ForecastEntry consists of 10 ForecastParts, and each Forecastpart contains 4 long values. )


    {} private void insertNewForecastTable (map forecastMap)
    DCBindingContainer bc = (DCBindingContainer) getBindings ();
    DCIteratorBinding ForecastIter = bc.findIteratorBinding("ForecastViewIterator");
    DC DCDataControl = ForecastIter.getDataControl ();
    ApplicationModule am = (ApplicationModule) dc.getDataProvider ();
    ViewObject forecastVO = am.findViewObject("ForecastView");

    Set key = forecastMap.keySet ();
    Iterator keyIter = keys.iterator ();
    RowSetIterator it = ForecastIter.getRowSetIterator ();

    While (keyIter.hasNext ()) {}

    Long timestamp = (Long) keyIter.next ();
    Timestamp ts = new Timestamp (timestamp);

    Line r = it.createRow ();
    r.setAttribute (0, ts);

    ForecastEntry forecastentry = (ForecastEntry) forecastMap.get (timestamp);

    int j = 1;
    for (int i = 0; i < 10; i ++) {}
    ForecastPart forecastPart = forecastentry.getForecastPart (i);
    r.setAttribute (j, forecastPart.getHistory ());
    j ++ ;
    r.setAttribute (j, forecastPart.getForecast ());
    j ++ ;
    r.setAttribute (j, forecastPart.getTrend ());
    j ++ ;
    r.setAttribute (j, forecastPart.getLimit ());
    j ++ ;
    }

    forecastVO.insertRow (r);

    }

    am.getTransaction () .commit ();
    Configuration.releaseRootApplicationModule (am, true);
    }

    Problem is: 3360 entered in this table or viewobject, it takes 10 minutes (!) to run this code.
    Bottleneck is the loop for and forecastVO.insertRow (r);
    Schedules are up 15 ms initially at 500 ms at the end.

    Someone has some ideas how to improve my performance?
    I do something wrong to try to create and insert 3360 rows in this table?

    Thank you.

    For massive insertions, you use JDBC to avoid the overhead associated with the management of the entity. You can get a PreparedStatement via the module of the application JDBC connection using the DBTransaction.createPreparedStatement () method:


    ApplicationModuleImpl apm = ...;
    PreparedStatement stm =
    apm.getDBTransaction().createPreparedStatement("INSERT INTO FOO VALUES(?,?,?,?)", 0);
    stm.setString(1, value1);
    stm.setString(2, value2);
    ...
    stm.executeUpdate();
    apm.getTransaction().commit();

  • Insertion of massive photos in a template?

    Hi all!

    I hope someone can help me understand the logistics of a program, I'm trying. It's not new or original, so I don't know there must be a better way to simplify.

    My team and I are going to be an event, and we'll take a lot of pictures. We want a way to apply a model around these pictures very quickly. In this case, we make it easy to look at her as if the photos are the first page of a newspaper.

    I take the floor to one of the designers of my business, and he seems to think that we would have to do manually in photoshop 1 by 1, but I know there must be a better way. There are tons of apps iPhone (etc) to apply models/skins to photos.

    What is the most simple solution to my problem?


    I thank very you much in advance!

  • USB readers of reformatting to insert (intermittent)

    My MacBook Pro since the recent OS X install 10.11.6, now completely reformat my external USB drives when inserting (about 20% of the time). The problem affects WD MyBook 2 TB external drives (x 2), WD MyBook Duo 12 TB NAS, as well as memory cards SD and my digital SLR via a card reader Lexar CF. The problem is intermittent. Sometimes, when I insert the above discs they mount as usual and display the structure of HFS files and any content file, on other occasions, there is a slight delay (about 40 seconds) after inserting a disc, then the drive is mounted as if it were brand new, straight out of the box. the 'hidden' EFI drive mount on the desktop, as well as a now empty and reformatted HFS disk partition. All data on the disks disappeared.

    I tried to run apple on the disks disk utility are deleted. I tried to run "Disk Drill". These utilities simply see the re-formatted and declare that readers have no errors or problems detected. I zapped my PRAM, I ran FSCK, I updated permissions, run all the cron tasks, run "Clean My Mac", emptied all the caches, etc. Even after all of this interview, I've known this same player re-formatting on the insertion of external hard drives.

    I lose the MASSIVE amounts of data when this problem occurs (Luckily most of the data are saved elsewhere however). One of the 2 TB drives was my Time Machine backup, so all the backups in this timeMachine are now lost. The NAS 12 to drive is a server backup, but I'll now have to re - build this backup (which takes days to copy all the data back). Camera memory cards are my biggest concern: my cameras contain each, 2 memory cards whenever I take a hit on the camera, the file is written on two cards: I've recently returned from a shoot day professional, inserted my CF card via a USB card reader only to find he had been "cleared" by the operating system , then I crossed my fingers and inserted the 2nd memory card camera that fortunately does not remove.

    At this point I can't be sure if these disks will be reformatted arbitrarily by the operating system again, because the problem is intermittent and I can't find a way to reproduce the problem (not that I really want to replicate). So I am VERY worried and fear now to connect external drives of any kind to my main computer. I am now back to my MacBook Pro 2006 for any external USB use, like I can't trust my newer Mac totally up-to-date.

    Any help that can be provided would be greatly appreciated!

    Questionable computer features as follows:

    Mac OS X 10.11.6

    MacBook Pro 15 retina "(mid-2012)

    Intel Core i7 2.7 GHz

    16 GB 1600 MHz DDR3

    Various disks USB, NAS, USB, memory, card reader Lexar cards


    I can only speculate what the cause to occur, but a main suspect would be "disk utility" installed by Western Digital. These things have tended to cause spontaneous loss of data you describe. Products may go under the name of "Drive Manager", "SmartWare" or words to that effect. If you installed anything resembling this description, uninstall it according to his instructions.

    The first thing you should so when buying an external hard drive's format using disk utility, thus erasing all unnecessary garbage manufacturer could include with it. For example, Seagate drives also include similar to Western Digital utilities. If I'm not aware of cause them similar problems, their "disk utility" software should also be eliminated with extreme prejudice.

    I tried to run "Disk Drill". These utilities simply see the re-formatted and declare that readers have no errors or problems detected. I zapped my PRAM, I ran FSCK, I updated permissions, run all the cron tasks, run "Clean My Mac", emptied all the caches, etc.

    Stop doing these things. Do not use any what non-Apple "disk utility" regardless of the origin or apparent popularity. "Disk Drill" has been known to delete perfectly good disks. Uninstall 'CleanMyMac' according to his instructions. Like all software 'cleaning up' in the same way by category, it's a scam whose sole purpose is to take your money. Just a Mac unmodified by this ill-conceived garbage clears spontaneously hard drives.

    Leave the cache files and only cron tasks. The permissions are no longer a problem with El Capitan. Don't mess with them. Let your Mac works the way it was designed to work - without the maintenance that you seem to think it requires.

  • I downloaded CS4 Design Premium and asks me to insert the disc 1, but there is no disk 1... Help!

    I bought Adobe Design Premium CS4 and the disc has been destroyed, so I found the download on Adobe and downloaded. Then, instead of just run the file I downloaded, I extracted and burned it to DVD. When I ran the Setup and pick out what I wanted to install and he said: ' "Please insert the Adobe CS4 Design Premium 1 diskette in drive G:\ to continue the installation.".

    I have a serial number valid because I connected my Adobe and obtained from my account.

    I just need to name the DVD a number so that it works, or what I need to download the file again and just run it from the massive file, I download?

    I come to find the 2 original files I have downloaded and run the extraction auto app and it extracted all for Adobe CS4 Premium\Adobe CS4\Design and when I run Setup.exe, it worked fine. :-{)

    Thank you for all the time by reading this post and thanks kglad, but I thought about it on my own.

  • The absence of H264 is getting really annoying. SOUL is massively not reliable to me, and first load compositions AE takes forever.

    So for some reason any tech Adobe decided to remove the H264, although it is an industry standard for Vimeo, Youtube, stream delivery as Extreme Reach and local BluRay companies controlling companies such as Replicopy.

    I'm about two steps from dumping that whole program, because the lack of reliability of my work on end of Adobe's embarrassing for me. It takes me 3 - 4 times to return something for a customer view / approve him. Why 3 or 4 times? Because the SOUL definitely likes to remove audio, insert frame weird solarized, or just lock-up seeds and say it will take another 35 + hours to make a 90 minute video that taken after 12 hours to render the CS6.

    I won't have to make a file DNxHD for friends/customers to look at. Not practical when it is 18 x compression H264 Youtube size. 109 GB and 6 GB.

    I'm losing my patience here, and I'm out of ideas. I found no reliable way to make more leave After effects. The more reliable, but it is still a shot-in-the-dark, that's when I load up in the queue of rendering a file DNxHD or GoPro Cineform then then transcode with SOUL, that is a silly and useless workaround. I just converted a DNxHD 109 GB file into a file H264 of SOUL with glitches at random, once again. Other lost 90 minutes. I have no idea of f ' n what to do next, I'm out of ideas. Try again the GoPro? Make an another DNxHD and transcode to H264 and cross just my fingers that work 14 hours of rendering?

    In short, the question:

    Windows 7 computer, CS6 ran without any problems.

    Try to make the short clips for customer approval as well as compositions of 90 minutes of EI through SOUL (running in who just got dumped audio problems, executives spilled/solarized and the program just lock up).

    What do guys do? You guys how would export a documentary of 90 min for a master BR? They do not take GoPro or DNxHD. They take H264. All the world run into problems I described here? Y at - it a patch/solution? Is there another intermediate codec that isn't incredibly huge?

    Here is where I am:

    -Export of EI by SOUL directly to H264-> error City (sometimes missing audio parasites, randomly, or the program just locks up completely)

    --Exporter export of EI as DNxHD, then transcode to H264-> city of error. The random glitches. This makes 12 times today by changing the settings every time, never getting to work.

    -Export of EI as GoProCineform, then transcode to H264-> WORKED!

    Now, if this isn't some stroke of luck, all my customer previews must be made twice (via an intermediate codec that is MASSIVE, almost 30 x more big issues than H264) due to infinitely wise Adobe decision to drop the H264, which I'm sure makes sense for someone somewhere and was not a capricious bet made by two drunken programmers.

    Thanks guys for the input. I'll doublecheck different hard drives (on different connections as well) just for safety.

  • Problem with a massive delete operation

    Hello


    This matter is v10g Oracle.

    An array is used to store user login information and other connection related details such as IP address, the date of connection, connection time, time of disconnection etc from a web application.

    This table gets big enough (3 million documents +) and is purged once per month of all records of 3 days.

    The purge is made with a simple deletion based on the date of connection CDAT and column DISX (logout = True/False)
    DELETE FROM LOGTAB where CDAT < sysdate-3 and DISX='T';
    CDAT and DISX columns are indexed. This delete operation can tale up to 10 minutes.

    Sporadic during the delete operation when problems users to connect or disconnect: for users trying to disconnect, operation UPDATE, resulting on the table currently being deleted seems to hang.

    For users trying to connect, there may be a delay (as the INSERT is pending). In the worst cases, all sessions hang until the button DELETE finally committed thus making impossible any connection for the duration.

    There is no conflict between the data being deleted and the data are updated or INSERTED.

    DELETION should only lock the rows that match the WHERE clause, so where is the claim arising out of? This could be the index argument?
    Is there a better way to manage these massive cuts on these high transaction tables? Partitions?


    Thank you in advance.

    Have you thought about this table partitioning? Of course, this would depend on whether most queries are watching the columns you mention, but that would mean that you can truncate partitions over 3 days...

  • Massive role change

    Hello, I m new Oracle peoplesoft campus, I have a problem, I do not change the roles of the different users of the application but I want to do massively, it remains the way to go

    Thanks in advance

    Diego

    I think we can do this from the back-end.

    PSROLEUSER is the table involved in the role of mapping to a user.

    Create a script to insert into the PSROLEUSER. (this table have only 3 fields to insert).

    Thank you

  • Shorten the length of the blade according to the State of an inserted SWF file

    My question may be advanced.  I am using Captivate 4 for this project.

    I am trying to create a manual online that describes a technical system.

    I created multiple SWF files for the various components and inserted them into a master project of Captivate.  I use the table of contents in the main project to provide navigation components.

    My problem is that the SWF file to show the various components have a visible bar of 'control'.  Since it is an event (without audio) we slowed down (some say too slow) for slow readers.  But given the control bar allows readers 'faster' the ability to speed upward and etc.

    My question, so if a user it accelerates and reaches the end of the file SWF slide continues until the 'period' is over.  For example, I have an embedded SWF which is 66 seconds long, the blade must be 66 seconds long to allow it to play fully.  I tried to adjust various settings and the settings of the imported video, but no matter what the video should be 66 seconds before I can do anything with the slide that hosts it.

    Any ideas?  I do not control the imported SWF file (which is actually a published Captivate project) and I do not master the file SWF Captivate "accommodation".

    Main reason for which is "broken apart", is can I outsource the various resources so I individual file charges "on-demand" and does not have a massive SWF file.

    Before asking, I thought using the Aggregater, but it does not work in Internet Explorer (HTM file) and will not cross the Preloader and my audience does not flash drives as I do.

    Hi Ziqiel, hope I will find the solution.

    I use the same technique as you Captivate 3. I insert the SWF on a main project. So, I insert a clickable area with options to "Stop the project until user click ' and 'no action '. You place this box anywhere on your slide where the swf file. It shut down the main project, but your swf will continue to play until the user clicks a button to continue.

    It is clear to you? And is it useful?

  • ignore the insert errors in a merge statement?

    Hi all

    I wonder if it is possible, somehow, to ignore the failings of the insert statement in a merge statement of bulk? The error encountered is the violation of a primary key. What is happening is that the different transactions share the same plsql procedure. Therefore, it could happen that different transactions will try to insert two rows with the same primary key.

    MERGE INTO table
    Using the collection
    WE (table.id = collection.id)
    WHEN MATCHED THEN
    UPDATE...
    WHEN NOT MATCHED THEN
    INSERT...-> it may fail for duplicates here

    The only solution would be to use 'updated massive day + bulk insert (ignore errors)' instead of a merger in bulk?

    Any help is very appreciated,
    WF

    What about using [DML Error Logging | http://www.oracle-base.com/articles/10g/DmlErrorLogging_10gR2.php#merge]?

  • Just updated to Sierra and updated Pages at the same time. Now when I try to select a line of text I find myself with an insertion point where I stopped by selecting

    Today, I updated for Sierra and updated to the latest version of the Pages. Now I find that I am more able to select a line of text. When I try to do, I find myself with an insertion point where I stopped by selecting, but nothing is selected. This is a bug in the new version of pages or get my wrong settings?

    You use a Wacom tablet by chance?

    Solution: Press the shift key, just before stop selection. And Yes, that sounds like trouble in the Sierra.

  • Sort order in Photos when using insert pages

    Writing reports using Pages and photographs uploaded to the works of really good Photos. Except that I can't choose to launch Photos but must scroll to choose when I have to scroll again to access the correct album.

    I can work around the album by ensuring that it is at or near the top of the list of Photo albums but I find it really frustrating that I can't set default Pages to access the Photos, because it's almost the only thing that I need to "insert" in all documents.

    Any ideas or am I stuck with the option 'do scroll down and select "?

    I really don't understand why people don't use the Drag and Drop as Finder has many brilliant ways, transparent, flexible display and sort images.

    The notion that you need another application to hold all your gear (usually in a format incompatible and numbered from Apple), that to have Apple stuff that, everything for you in their next series of musical chairs of the Titanic, are so weird for me.

    All do as you are told just because they told you to do what you said and can't imagine doing anything else?

  • Can I insert a nano card into an iPhone 6 to activate and get him out?

    I got an iPhone 6 or 6 s one of my friends. He said that I needed to provide my own sim card. I know that you use a sim card to activate the phone. In my case I will not use the iPhone as a real phone but like an iPod. I understand that the sim card doesn't have to be an active card. But it can not be disabled or theft. But my main concern is: can I insert the nano for the activation of start card and put it, I can remove it and it will still work without it in?

    Note: I'm not 100% if the iPhone is a 6 or 6 s?

    Yes. It takes a SIM card to activate the device with Apple. Once activated, you can remove it and use the iPhone as an iPod touch.  Best thing to do is activate airplane mode, then go to settings, wifi and re - activate just wifi (this way the cellular radio stays turned off the power, since you do not in any case).

  • I downloaded a windows file. I want to work with the document. I want to insert the information. How can I do this

    How can I work with a pdf file of windows? I want to insert the information. Edit the file etc.

    You may be lucky with select all > copy > paste into a new document in a robust word-processing or text-editing application

    A PDF is designed to be READ (for the most part)-only "areas" can be "filled" and printed/saved

    After the first, you can then save it as a PDF from the application you are using - usually the function print rather than the Save as function
