What is the best way to treat 500 million data

Hi guys,.

I have

Any help would be much appreciated.

Do not use bulk slow processing. Despite the term "in bulk', it remains online treatment. Which is slow. Not perfect.

Use single read / write cursors (as oppose a reading, PL/SQL and a slider to writing).

Use parallel processing. PQ or DBMS_PARALLEL_EXECUTE.

Also consider partitioning if you have permission. This feature is well suited to deal with VLTS.

  • What is the best way to treat the pf24 Canon files?

    I'm working on a project shot mostly with pictures of Canon DSLR (1080 p, 24 fps) but now I would like to add some images from a Canon, recording in AVCHD format camcorder. It seems that most presence of shooting at 24 fps or as Canon calling pf24. The question is, is first or media encoder able to interpret images of canon and good converting 3-2? Or should I save in 30 frames per second (or pf30) and to convert the 24 frames per second in media images encode before adding it to my project? Don't forget that I can not just shoot everything in 30 p because most of the project is already shot in 24 p. Also, I use CS6. Does anyone have experience with this? Thoughts?

    OK looks like I found the solution. You must take the pf24 images in After Effects and use the interpreter image drop-down list, and then click proposal 3:2 pulldown button. Right click on the file again and choose the make-up of the selection mark. Then render the composition in a full resolution AVI (1920 x 1080, 23.976 fps) and put it in your timeline. Disappointment is that you must do this for all files and the files are large (approximately 8 gb per minute), but given that your choice of output is limited after effects avi files full resolution are the best choice to maintain the quality.  Adobe really needs to add a hypothesis 3:2 pulldown button in preview to interpret footage dropdown. It was much more difficult to.  Here again, I guess that canon created the problem in the first place. Thank you very much Canon.

  • What is the best way to read this binary file?

    I wrote a program that acquires data from a card DAQmx and he writes on a binary file (attached file and photo). The data I'm acquisition comes 2.5ms, 8-channel / s for at least 5 seconds. What is the best way to read this binary file, knowing that:

    -I'll need it also on the graphic (after acquisition)

    -J' I need also to see these values and use them later in Matlab.

    I tried the 'chain of array to worksheet', but LabView goes out of memory (even if I don't use all 8 channels, but only 1).

    LabView 8.6

    I think that access to data is just as fast, what happens to a TDMS file which is an index generated in the TDMS file that says 'the byte positions xxxx data written yyyy' which is the only overload for TDMS files as far as I know.

    We never had issues with data storage. Data acquisition, analysis and storage with > 500 kech. / s, the questions you get are normally most of the time a result of bad programming styles.

  • What is the best way to transfer the file to a new larger internal drive?

    I am running win 7 ultimate.  I had two hard drives of 500 GB.  C is partitioned to 120 GB (not enough) I just installed a 1.5 terabyte drive.  What is the best way to transfer my data? I would keep the 500 GB (now C: and D :) and add the 1.5 to, I also have a 2 external to that I tried to move my libraries at, but I'm confused my system.)  I don't know much about indexing or mapping.

    \

    Consider transferring all the files that are currently in the second partition of 500 GB drive that is hosting the C: drive (you have referred to as D :) on the new drive.

    Once you have done this, you can then delete the D: partition since this 1 hard drive. This would then extend the C: drive to actually use all the 500 GB drive. Finally change the drive letter for the 1.5 terabyte disk d: it in disk management ( Diskmgmt.mscRun)

    So in the end you have a 500 GB C drive and a 1.5 TB drive D.

    When it comes to move libraries Windows has a utility to do it for you. If you click on your username at the top right of the menu start all your user profile directories are displayed. If you right-click on each one and select Properties, those that support this feature will have a tab 'location '. In this tab, it displays the current location of the file, but has a button "move". You move the folder and all its files and subfolders in a new location and update the references, the system uses for this folder.

    So if you created a folder on the D drive say 'Juli-year' and you right-click on Favorites, some properties, then on location you can move this summary folder in C:\Users\username\Favourites to D:\Juli-An\Favourites. Not all folders in the user profile supports this but all the c library files and a few others.

    Of course if you did as I suggested and ended with a 500 GB C drive you may need.

    Hi Bill,

    Can you just check to see if the report actually adds the ID attribute for each TD. In a normal report, if you include the ENAME field, for example, all TD in this column have an ID = "ENAME". If this is the case, you can use document.getElementByID ("ENAME") to retrieve a collection of these - this would be faster browse this collection through the rows/cells.

    In addition, if possible, you should only perform research and calculations once. You have mymonths [j] several times in loops - create a variable to hold this for each iteration of the loop and refer to the variable. You also n = l_Rows.length in loop definition - put this above the loop that you only need to calculate this time.

    You can also find more efficient to perform ObjectName. style.display = 'none' * instead of the html_HideElement() method as it is easier.

    If FF3 was a bug in which does not hide the NECK tag columns, I suggest using those rather--it would mean the creation of a new report template, but it would have been the quickest method as you can style an entire column to style her NECK tag (drawback, it's that the NECK tag cannot be created dynamically so it should appear in the report model).

  • What is the best way to buy an iPhone Unlocked 7?

    Hi all

    I am currently using T-Mobile and want to get the new iPhone 7. Since there is no option for a sim-free iPhone, what is the best way to buy the new iPhone? Should I get the T-Mobile one full fare? I know that he will be released version but it will come with a T-Mobile sim so what will do with the sim card? Put it away or give it to T-Mobile? Or should I wait for the version without card sim to appear, which I don't think that will come out until November, and I don't want to wait that long.

    Thank you in advance.

    If you do not want to wait to pay full price for the model from T-Mobile.  You can do whatever you want with the SIM card.

    The best thing for you to do is to make a backup of your Firefox profile. It is a folder that stores bookmarks and Add-ons that you can then add to the reinstalled Firefox on your new operating system.

    The easiest is just to copy the whole profile.

    Close Thunderbird

    In windows Explorer, select all and copy.
    just stick on a thumb or other portable media to read/write (not the CD or the DVD)

    on the new Machine to repeat the troubleshooting and close the steps to get the current profile folder

    This time all the portable media stick in the profile to replace what is there

    What is the best way to manage applications if tat I can use them, but no pork then my mem space?

    y at - it an app that manages the apps?  should I delete and re-download a few apps later?

    I would like to take advantage of many more applications that I believe I have space for.

    You can see how much storage resumes via the settings app > general > Manage Storage - this screen lists each app space (the application and its content), total by selecting an app on this screen should tell you how much space the application content (files, documents, etc.) resumes.

    y at - it an app that manages the apps?

    No, iOS is a sandbox environment, apps can control or manage other applications.

    should I delete and re-download a few apps later?

    Depends on the app. deletion of an app will also delete its content, if it is an application where its content is important (such as documents), and that content is not stored elsewhere (e.g.)  Dropbox or cloud server), you may lose this content by deleting the app.
