performance issues when you use adapter jena setSessionQueryDOP / oracle 12 c

Hello

When I create a ModelOracleSem instance with the command:

Model = ModelOracleSem ModelOracleSem. createOracleSemModel (oracle, modelName);

Everything works fine (the creation of the instance takes less than 1 s), however if I use: oracle.setSessionQueryDOP (8), the establishment of the Forum is very slow over 15 years. I do not suffer this situation before migration to 12 c

Am I missing something?

Hi Arnaudz,

Use 'DEGREE = 8' should be a little more effective than the "DOP = 8" because that parallelism is defined at the level of education with degrees setting.

Your material is quite impressive!

Thank you

  • Performance issues when you use HTML5-Articles

    Hello world

    We build an application where we use HTML5-sensitive inside objects.

    On older iOS Devices (iPad2 iPad4 for example) and the performance is so bad that it is not really usable. Take for example up to 15 seconds of opening an Article downloaded until it is fully restored.

    We have a lot of photos and videos inside but inside the browser OS, it works a lot better.

    Is there anyone who has had the same issues or any idea how to optimize performance (especially on older devices)?

    Thanks in advance and best regards!

    Lars salvation,

    The control of the OS used to display content on iOS is a different rendering than the OS browser technology and has different performance characteristics. In particular, it is slower on older devices, such as the iPad 2.

    Based on your description my guess is that your image size is driving performance issues. Take a look at what size in pixels are your images and aggressively, re - compress. I had successful scaling of images to 50% of the size I think I need and then save them in JPEG format at a quality level of 7 (or even 5) in Photoshop.

  • In the face of slow performance issues when you use Microsoft applications.

    Original title: The Office Windows and student 2010

    Windows is slow to opening any windows file (ms word, excel, windows live mail, etc.), and more when you type in one of these applications, there is a striking shift. I did all the diagnostics repair in programs and features, troubleshooting, disk cleanup, defragmentation, etc. I ' don't know what to do next. As I type this question, it is not a lag in typing.

  • Performance issues when you use TimeWarp

    Hello

    I'm trying to understand why a CS6 updated AE to date is to have performance on a generation problems relatively high-end. I'm trying to use the time warp effect to make the scenes of idle but AE runs very slowly once that I was drag in a clip that its unusable.

    I were read stimulating performance article which shows how to increase the hard drive cache (I'm under it an SSD in passing) and adjust the amount of RAM and the number of cores is used, has no effect.

    Here is my card of build:

    CPU: i7 3770 k @ 4.2 Ghz

    RAM: 16 GB 1866 mhz Corsair Vengeance

    SSD

    GPU: 2 x GTX980

    OS: I tried it on Windows 8.1 and Windows 10 Technical Preview, no difference. Both fully implemented to date.

    I also tried the Cloud creative trial version to see if it gets better, here, it works more slowly.

    Any help or contribution is appreciated.

    It might be the film.  Things like AVCHD, mp4, h.264, and mpeg compression interframe - not every image has complete image information... just things that have changed from one image to the other.  If you mess with time use, AE must rebuild the incomplete frames first, and THEN it must mess with time.

    The fix - use a good intra-image codec.  I love quicktimes ProRes 422, Photo JPEG, PNG or animation.

  • Performance issues when you build a large crossroads

    Hello

    I have a performance issues when you build a large crossroads.

    So here's my situation:

    We use Discoverer Plus 10.1.2.45.46c
    Database Oracle 9.2.0.6 on Windows 2003
    OAS 10.1.0.3
    1.5 GB of RAM on my PC

    -J' planned a workbook with 1 single worksheet that takes 2 minutes to run. The table generated in the database to store the results from 19 columns and rows to about 225000 (I know that's a lot, but it is what the customer needs).

    -When I opened the workbook, it takes about 2 hours to recover the data. The data is retrieved in groups of 1000 and at the beginning, the lines are read much faster than at the end. There are also 15 minutes more to build the crosstab. So overall, it takes 2 hours and 15 minutes for the crosstab display on my screen.

    Can someone explain to me:
    -Why does take so long?
    -What can I do to improve the execution other than changing the application or displaying the results in a regular tab? Is there some setting that I can do on the database of the Oracle Application Server?

    Note: I have reproduced the worksheet in a simple tab and demand it. The table generated in the DB to store the results is the same and it takes only 2-3 minutes to open this spreadsheet and extract all lines.


    Thank you!

    Mary

    Hi Mary
    If you have 225 000 lines in your basic spreadsheet, then it will take a lot of time to produce a crosstab. The reason is that Finder can not calculate how many buckets he needs until he has read all the data. I can almost guarantee that with 225 000 lines to read and manipulate that you are short of memory.

    You might be better suited someone create and populate a table with the results you need rather than try to get the discoverer to calculate values in crosstab on the fly. If the final result of the crosstab is a few lines of aggregated data, then this is what is right for your table. The advantage of using a table and a few SQL (or PL/SQL) is that you will not be using your local computer during the aggregation / sorting phase. Don't forget a crosstab also sort based on the values in the left columns, the columns you have aggregations (buckets) you will have and most necessary sort. Using a table, you can index or even partition the results that will make for a much faster recovery.

    As a tip, recommend Oracle, confirmed by myself during the exhaustive tests, no do not build large paintings to double entry due to the performance of touch that you will have. The tables are much more efficient because you can pull back x lines at once. You can't do that with a crosstab and all values must be read before that whatever it is is displayed.

    Does that help?

  • MainStage "lag" when you use the SPACEBAR as 'play '.

    Hi all, I'm relatively new to Mainstage (V3), and I'm hoping to use it for the first time this weekend to play the extra backing with a band tracks

    The issue I'm having, is that with the SPACEBAR of laptops on 'PLAY '. It is often "lag". or simply does not start the song. I have to wait a second, then hit again, it will work.  It is almost as if in Performance mode, when you use the down arrow key to select the next song, the 'focus' is on the list of patch, and if I click in the background where are playback buttons and stop, THEN that will work. I have not, however, been able to reproduce this particular behavior on a consistent basis.

    Everyone knows the same thing? Or why it is so 'all or nothing '?

    And a question important much donor... I gave all my reading titles to the waveform appropriate the other night (so I could visually see the waveforms above the attenuator as offers of backing track model), however, once I was moving songs in a different order, which stopped working. No idea why?

    Thnaks in advance

    About the offset by hitting the space bar, a thought occurred to me.

    How Mainstage allocates 44.1/16 bit wave files used in the reading plug-in? Which means, when a song is selected, which uses, for example, to separate the 5 cases of reading, one can assume that these audio files used in that song would need to "load" first.

    Anyone know if this is how Mainstage works?

  • Performance issues when coming out of sleep

    I recently built a gaming PC. On Christmas day, I finished putting the thing together. It has an Intel i7-4790 CPU running Intel HD Graphics, 8 GB of Corsair Vengeance RAM, an Asus Z97 - A Mobo and a 2 terabyte Seagate HDD. I installed Windows and put everything in place. Then a week later, my MSI GTX 970 arrived in the mail.

    So, I take the thing to sleep and decreases the performance of the whole thing. Videos YouTube stutter, simple as games fight of World of Tanks to run at its usual rate of 60 fps. To avoid this, I simply restart my comp and then it works fine. performance is back to normal.

    A few weeks, Windows gave me a message on one of the Nvidia drivers causing performance issues when you wake up from sleep. I don't think a lot of it and rejected it. I'll try to reinstall all my Nvidia drivers. I uninstall the Intel HD graphics driver a few days ago and has not changed anything. I would appreciate an answer to this problem because I would like to continue to use the "sleep mode" because it consumes less energy and prolongs the life of my case of LED. Thank you!

    A few years ago it was recommended to remove the battery of the laptop if the AC adapter is plugged. What keeps the constant charge battery
    New age of batteries are better you can leave the battery in the Bay it s ok and it should not affect the performance

    However, sooner or later each battery would die it s only a matter of time, you know
